====Intro [itro] ====

Well to be honest I had a VERY hard time w/ the final boss form of Sigma, so I
spent plenty of time nearly perfecting the bosses and sigma forms. Yes the game
has been out for years, but I'm playing on the newly released 'MegaMan X
collection' on the PS2. My way is not the best for ALL players, but I hope that
it helps w/ everyone's playing exerience. I have been a fan since the NES days,
and loved when the X series arrived. My "style" for writing may not be for
everyone, but if you think somthing could use a little "ammending" lemme know.
Also I will not be using the attacks 'official' name, but if your familer with
the attacks, you'll know what I'm talking about. And yes that is my FIRST EVER
text graphic (the title). I'm sure it's lame compared to others, but you gotta
start somewhere.

====Boss Guide====

I will list the order in a normal playthru that you 'should' encounter them, as
according to what I found best/easiest.

==============
X [x4_bg]
==============

Playthru-- Web Spider >> Split Mushroom >> Cyber Peacock >> Storm Owl >>
Magma Dragoon >> Frost Walrus >> Jet Stingray >> Slash Beast

Final Stage-- At this point it really doesn't matter, I started at the bottom
and just went to the closest transporter from there, getting some life at the
top if needed. Now that you have all of their weaknesses, do them in whatever
order you wish.

Comments: I suggest getting X's upgrades (like always) they help things
tremendously in the "weapon energy" dept. Since finding them can take some real
time and effort, I'm only going to list what stage the upgrade capsules are on.

++++Web Spider [x4_ws] ++++

--Playthru-- Your first boss. A little tough since you have nothing, so your
health is somewhat low and no weakness or weapon upgrades. However, it's still
pretty easy. He'll drop the the top, usually not low enough to hit u w/ his
body if ur on the floor, he'll pause a second and then let a electric web go
that will float ur way. You can jump and get a slash in before it fires a web.
Two ways to doge these webs: 1) if ur on the left side of it when it fires one,
dash to the right side, underneath the web and it will miss, just don't let it
get too close, and 2) climb a wall, and jump over it towards the middle and it
should miss. Those are easily dodged either way, just be wary of the timing of
ur jumps, if u ARE caught in one, dash, jump, attack and move to get free, it
will damage u while holding u in place. Once it has lost about half of it's
life, it will come down in the middle of the screen and make a 4-wide web space
to crawl all over. at this point he stops disappearing (yay!) but attacks more,
and has a new attack (boo...sorta). now u have to be more careful not to run
into it. it will still let out electric webs that can hold u in place, u have
less of an area to move around in, but still pretty easily dodged. It's new
attack: it will stop like it's going to let out a web, but it's
"back/butt/whatever that thing is" will open and throw 4 mini-spiders up and
onto the floor. they will land, and pause for a second, hopfully you're
'charged up', if so then let it out and take out all 4 spiders. If you missed
any tho they will either run left or right, and up the walls till the
disappear. You'll be busy dodging and trying to get attacks in, just keep your
buster charged up and let it out when there's an opening. If you're charged up
before he comes out of the tree, you CAN hit him twice. Once before he shoots
out the web/mini-spiders and once just before he retreats. Once he is half way
down on his life, just watch out for when he pauses and lets out the
web/mini-spiders, because you have no double jump and need to use the walls.



++++Split Mushroom [x4_sm] ++++

--Playthru-- Good news: you have his weakness with web shot. Bad news: you
don't have the weapon subtank, and you may need it. But with that being said, 
it's still not that bad at all. Your web shot is his weakness and if you're 
very quick, you can make this fight very easy and fast. He will jump to midway
up the wall and let off 6 clones of himself, you can jump on the opposite wall, 
jump to the middle of the room, and let out a web shot. If done quickly enough 
it will hit him before he lets off a clone. If not dodge the clone(s) that he's 
made. He'll then drop the the floor and flip to the other side of the room and 
jump up and start the same thing. If he happen to get out the 6 clones and he's 
not hit imediatly, then he'll jump to the top center of the room and make a 
copy of himself. If that happens, just follow the 'solid' one (the 'copy' will 
be semi-tranparent till it lands) and hit him with a web shot, they will then 
flip and switch sides (you don't need to jump or do anything, they'll jump over 
you). Just do hit him 2 more times and he'll go back to making clones of 
himself. If you do run out of web shot energy, just charge up your buster and 
lay into him before he can get those copies off. Unless you're really bad at 
hitting him with web shot, you should only have to hit him a couple of times 
with the buster.



++++Cyber Peacock [x4_cp] ++++

--Playthru-- This guy sux. He's weak to soul body, the new attack from split 
mushroom. But almost garunteed you'll run out of weapon energy too soon. It's 
tough but you can beat him with ONLY soul body. When you use the attack, it 
makes a "mirror" or "shadow" of you that disrupts Cyber Peacocks 'data' and 
forces him to disappear again. The key here is you need to hit him twice per 
'shadow'. Unlike other attacks, the shadow does not go away when it hits a 
target (or at least Cyber Peacock for that matter). He will either appear on 
the left or right sides of the room, about midway up and launch an aimed laser 
at you. You can jump and hit him with a soul body easily here, which will make 
him disappear. Now for the most of the battle he will try to appear on your 
space, or just infront of you and let out an attack. He will either appear with 
his 'feathers' spread out 180 degrees (which is a 'stabbing' attack that has 
pretty good distance because of where he appears) or with this 'feathers' 
spread up and donward (if he does this, he'll jump up and have a beam in the 
gaps of his 'feathers' with a short distance, but it can still hit if you are 
too close). The key here is to keep dash back and forth, but don't changed 
directions unless you just hit him or he just disappeared. It tricky but if you 
can hit him with soul body quickly, and then before it goes away hit him again, 
this will make you be able to use just the special attack. Just keep in mind 
that you need to keep "double hitting" him or you will run out. If you do run 
out of weapon energy, keep your distance, charge up, and let off attacks when 
it's clear. 



++++Storm Owl [x4_so] ++++

--Playthru-- The hardest thing about this fight will be your use of the newly 
aquired laser beam attack you got from Cyber Peacock. It can seem very akward 
at first but you will get used to it. When you have it equipped pressing up or 
down will move the "crosshairs" up and down, this way you can move left and 
right like normal. You can only fire a laser when an enemy/target is in the 
crosshairs, so wait till the old Owl gets close. He doesn't move TOO fast so
predicting about where he'll be and firing the laser is pretty simple. It does 
a very good amout of damage and is very easy to hit. For once, don't worry 
about your weapon energy (after this fight I barely had 1/3 less than a filled 
bar). When he is hit he'll flash black and white stripes and fly off. He'll 
re-enter the room at one of the 4 corners. You can move a little to make 
hitting him a little easier and faster. You may get hit a couple of times, but 
unless you're nearly dead before this battle, it shouldn't be too hard. Here 
are his attacks listed, just in case you need it.

  1) he will stand or hover in one of the 4 corners of the room and let out 4 
green orbs, one at a time, they seem to go to random locations but after they 
all get there he will take off across the screen and leave, but once he starts 
moving so do the orbs, they will come after you. very tough to dodge, and 
they're invincable, just do ur best. If you can get him in your "sights" try to 
let off an attack, if it's blocked by one of the orbs it'll do you no good, but 
it's worth a shot, you just may get it thru and help move things along.
  2) he will stand on the left or right side and make 3 tornados appear around, 
and on, you. You can see them forming below you before they actually hit, so 
you can dodge out of the way pretty easily. If you pre-aim and then dash to 
avoid the attack, you can easily counter attack quite effectively.
  3) he'll fly in on the left or right and fly slowly to the other side of the 
screen, usually go back and forth if u don't attack. if you jump, he'll swoop 
down and grab you, then slam u into the ground, then he'll fly off. You can 
reach him with the laser without jumping, so as he goes back and forth just 
nail him with the attack to make him fly off.



++++Magma Dragoon [x4_md] ++++

--Playthru-- Unlike Zero, you now have the only weakness for Magma Dragoon: 
wind slash (from that Owl guy). That attack alone makes him a cinch! The attack
will go out from your sides, and begin to angle upwards. When you first start 
just hit him with wind slash, don't worry if you're hit, soon you won't worry 
about that. Once he's hit he'll jump to the edge of the platform and try to 
launch an attack, simply walk a couple of feet over and hit him again. Continue 
walking back and forth hitting him when he lands and he'll go down in no time. 
If you have the buster upgrade you can charge an attack that will go directly 
left and right of you, without going upwards, but truly it doesn't do more 
damage.



++++Frost Walrus [x4_fw] ++++

--Playthru-- **note** There's an easy heart tank early on in this stage, but 
you can only get it when you have the fire uppercut, which now you do. Just 
make sure to take the lower path at the begining of the level and you will come 
across it. **end note**

Can be a little tricky but not hard. Keep in mind that you can practially walk 
and stand under his chin and not get hurt. Since your new move (fire uppercut) 
is his weakness that is somthing you should keep in mind. So therefore you CAN 
hit him very easily with the move without getting hurt. For the first part of 
his life bar he will get hit, which burns off his icy teeth and other things, 
and then slide back to the wall behind him, at first that's pretty far, but 
then it should only be a few feet. Then he will slowly slide forward across the 
room in a VERY poor attempt to hurt you. Just climb on the wall he is sliding 
towards and wait till he gets close. Keep in mind that his BODY, not his hand, 
will hit the wall, so just time you're dash-jump right and you'll easily avoid 
him. remember landing on hands will not hurt you. Now for the second half of 
his life bar. Once you hit him with the flaming uppercut he will still slide 
back to the wall, but will now stand up (you can't hit him at this point yet) 
and blow cold air out to make a giant icicle. It will fall to the ground and 
shatter into smaller icicles that go outward. All you need to do is go to the 
other wall and wait for the icicles to fall in front of you harmlessly. Then 
just walk over and hit him again, and walk back to the wall. Yes it's that 
easy. If you're having a problem with the icicles, you can find a spot in 
between them where you are safe so you don't have to make it back to the wall.



++++Jet Stingray [x4_js] ++++

--Playthru-- Weakness: Ice shield, which you just so conviently got from that 
big walrus guy. This may be a little tricky to get on the "rythm" but you 
should still not have TOO many problems with this. The most tricky and damaging 
part in this battle is getting him on the 'routine'. He will usually hover down 
to the opposite side of the room when you begin the battle. From here he'll do 
two things, either quickly swoop down across the floor and come up, or pause 
and let out mini-stingrays that go along the water, hit the wall and go down 
following the wall and floor. Once he's let out 4 of them he'll swoop across 
the floor. You're best idea is to wait to see what he does. If he swoops just 
dash-jump over it and get back on the left side of the room. Once you see him 
coming down jump. At the peak of your jump use the ice shield. That will freeze 
him and he'll bolt off upwards. Just stay on this side he won't change sides. 
Continue jumping a hitting and he'll go down pretty soon. I will list his 
attacks and how to counter/dodge them.

  1) room swoop. he will hover for just a second above water and then swoop 
down and across the room. if your on the opposite end of the room from him you
can either try to land the ice shield on him or dash-jump over him.
  2) blue mini-rays. he will hover at water level and let out 4 mini-rays that 
will go across the water, down the wall, and across the floor. Once the 4 are 
out, he'll do a room swoop. You can hit them all with a charged shot and beat 
them, but watch out for the big boss. 
  3) red mini-rays. same as blue ones but they will not wait for the wall
before they come down, they will come down whenever they get above you. so if's
very hard to dash under them. he will still room swoop after the 4th one of
these as well. Use the same technique as the blue ones here, but they're harder
to hit. 
  4) vertical dash. he usually does this very late (ie: low on life), if he
does it at all. I only saw him use this attack as Zero, not as X. He will dash
(like after he breaks the ice) downward, and then almost immediatly, upward.
just dash from one side to the other, try not to "back track" over your own
dashes to quickly or he may be rising right behind you. IF you get this attack,
just work on dodge it, don't try to counter it's too sparatic and difficult,
you'll just be wasting weapon energy.



++++Slash Beast [x4_sb] ++++

--Playthu-- Weakness: ground shot. yes you just got it from Jet 
Stingray.....starting to see a pattern here? Yay, I hoped so. The only hit you 
should recieve is possibly at the begining. If he opens up the fight with his 
"double slash" attack then you may get hit, if he does his usually "growl" then 
you should be more than fine. Equip your ground shot and let one out. The shot 
will float slowly to the ground and move pretty quick. Be prepared after you 
let out a shot and it hits him, here's why: as soon as he's hit, he'll pause 
for a second (like with most bosses when hit with weakness) then do his dash 
slash attack (he will lift his hand, and it will have a purple-ish "star" 
flashing.), but he'll only go to the other side of the room, no back and forth 
action when he does this (if he does his 'dash slash' attack without being 
provoked, it's a back and forth attack). It's very easy to dodge, jump, and 
either hover or dash over him. Now's a really good time to turn around and let 
out ANOTHER attack. He'll dash, you'll dodge, and eventually, he'll die....err 
explode. INCREDIBLY easy.



++++Colonel [x4_cl] ++++

**Note** This fight was done with only 6 heart tanks and no subtanks *end note*

Pretty easy, but no weakness, just like most of the final bosses here. With 
that being said, I'll list his attacks and how to dodge and/or counter them. 
Most of this battle will be spent on the wall.
  1) invis-a-slash: he'll have disappeared from somewhere, and reappears 
infront of you, where ever you are and slash imediatly. After a few of these 
you can get the timing down VERY easily. Unfortuanly X's jump isn't quite high 
enough to avoid the hit, so either stand a few feet from the left wall and time 
it so you dash away from him as he appears, or climb up the left wall and stay 
at least a quater of the way up the wall. After this he'll usually invic-dash
to the far right for his next attack. If your quick, and very quick at that, 
you can get a clean charged up hit on him before he dashes away.
  2) invic-dash: usually after the invis-a-slash, he'll dash to the far 
right (or left, basically AWAY from you). While he does this he's completely 
invicible. So don't waste a charged up shot now.
  3) hi-low slash: he usually does this the whole screen away. The first 
slash is hi, second one is low (hence the name). First one is too high to jump 
over, so use the wall to climb up. I don't recomend dashes under it because the 
second one is low and dashes to it can be hard. So just climb the wall till he 
disappears and does another attack. The only way to counter this one is to hit 
him JUST BEFORE he starts the attack. If you do it too early he'll just block 
the attack and no damage to him. If you wait to long you'll get hit by the 
slashes. So try to time it that he gets hit right when he starts to slash.
  4) floor bolt: he'll appear in the middle of the room and hold his 
sword up and charge electricty. It will then travel into the floor, which can 
hurt you, and then shot upwards. Easy to dodge, and your favorite attack to 
counter. As soon as he sticks his sword up, nail him with a charged shot. Now 
climb the wall, and wait for the electric balls to form on the floor. They 
won't be there long, but long enough for you to see where they're gunna go 
(they do this the exact same way each time too). Now just jump from the wall 
and hover in between where the electric is coming up. Once it passes go back 
and climb on the wall. He likes to do the invis-a-slash after this attack.
  5) jump slash: he'll start to do this after about 1/2 his life is gone. 
He doesn't do if often, but be wary of it. He'll slash like his other slash 
attack but will jump about 3/4 up the wall, this attack also lets off a pink 
slash that goes out. You should be on the wall so you may never even know this 
attack happened.
  This can be a long battle because you have to time your attacks and 
dodge almost all of his. But just keep dodging and he'll go down.

**note** Don't give up if you come into this fight with very little life. 
I entered and won this battle with only 2 bars of health. Just a statement, i'm 
not bragging **end note**

++++Double [x4_dl] ++++

*Note* This fight was done with only 6 heart tanks and no subtanks *end note*

Another no weakness battle, but his pattern is pretty simple and you'll beat 
this faster than the Colonel. Once again I'll list his attacks and what to do 
to dodge/counter.
  1) "danger": he says that before he launches a spinning blade-thing at 
you. It will stop for a little bit when it get to you and it's too big to 
simply jump above it. Best thing is to jump to wall, and over it so you can let 
a charged shot out.
  2) swoop-sweep: he'll jump and hang on the wall next to him, then 
'swoop' to about the midway point on the floor, pause, and then 'sweep' to 
whichever side you're on. just dash away from him when he swoops, and then 
hover above him, or close to him and he'll 'sweep' under you. Once he does 
that, just let out a charged shot. 
  3) huge slashes: he will let out a huge slash that moves kinda slow, 
but covers 3.5/4 of the screen, vertically. Dash under the first one, then head 
to the wall and quickly climb it and stay in the very top corner to dodge the 
next one.
  Once you get his pattern and attacks down, it'll go even quicker, just 
make sure to dodge above all things, because he does give you quite the 
opportunity to hit him.



++++General [x4_gn] ++++

*Note** This fight was done with only 6 heart tanks and no subtanks **end note*

Not that bad at all with X. I found his most common attack to be the "hand 
launch". He'll let out his hands, that separate from his body and cruise back 
and forth, left and right, while blue orbs fire from his arm sockets that his 
hands were in. Unless the hands smash you against the wall or you touch the 
blue flame coming out of the back of them, they don't hurt. So mostly you need 
to dogde the blue orbs. They will launch at you, so don't stay in the exact 
spot for too long, and don't too quickly back to a place that you were just at. 
Just charge up your buster shot and let it rip where his tiny head is. You 
probably won't actually SEE his head, but you should know about where it's at. 
You'll also know when you hit it by the flashing of his body and lowering of 
his life gauge  :D. He may also come over to the left side of the room and 
shift up and down, and may even launch a laser attack. You should be completly 
safe from any attack he does on that side by just staying in the top left 
corner. After a little bit, he'll go down, quite an easy boss for so late in 
the game.



++General Tips for Final Battle [x4_gt] ++

OK now is the infamous "fight all 8 bosses and final boss" stage. Now is the
last chance, and a good time, to get the missing armor pieces, heart tanks, 
and/or subtanks you've been missing. It's possible you'll need them all except
the weapon tank (if you get the head upgrade). Make sure to go fill up your
subtanks and lives at the Snow Base stage (Frost Walrus). Honestly some of you
might take 8 or more lives to do this (like me BEFORE my MMx break). Others may
be able to do it on your very first shot (like me AFTER my MMx break). If you
feel yourself getting to "stuck" and just plain frustrated, I suggest taking a
break, maybe playing a different type game for a few hours, or a day or so, then
come back and slaughter Sigma, trust me it can work that way. Last note, I will
not be covering the Bosses the second time around, really if you need to see how
to beat them, look above, there's really no change in stragey this time around,
and it's possibly easier because you have everyone's weakness.



++++Reaper Sigma [x4_rs] ++++

Very easy, make sure to NOT LOSE health with this first of four forms. He'll 
appear above you, just use 'fire uppercut' and it'll burn him and he'll
disappear again. He'll reappear and do that one more time. Once he disappears 
for the second time you have two choices on how to dodge his next attack. The 
attack is: he will appear on the opposite side of the room from you, up high, 
and slash across the room with his sicle. It's too low to dash under, but with 
your leg upgrade you can hover above it and under him to dodge it all. Or the 
other option: once he disappears go to any side of the room and climb up the 
wall. Wait near the top and as soon as he slashes jump, and air dash over him 
and fall to the ground. Whichever way you dodged it, just wait on the ground 
for him to start appearing again. This is actually easier than it sounds. Trust 
me.



++++Sigma [x4_sg] ++++

You don't have to get too close to him, wich will help this fight. since this 
second out of four form has so many attacks and they HAVE to be countered I 
will list them and how to counter them.
  1) boom-a-sicle - He'll jump, pause, then throw the sicle to whatever 
wall he's facing, it will go out, down the wall, under him, and slightly behind 
him and then back to his grasp. You can hit him 2-3 times here. First when he 
jumps, second after you dash under him and jump and hit his foot, third just as 
the sicle comes back to him.
  2) sicle combo - this attack will vary on difficulty all depending you 
where the sicle lands, and where it lands is up to you. He'll jump and pause a
second like in boom-a-sicle, but this time the sicle will go out and stab into 
whatever surface it lands in. You WANT this to be in one of the walls, trust 
me. He'll do this attack after the boom-a-sicle so you'll know it's coming. 
Climb on a wall and wait till he's NEARLY thrown the sicle (timing can be hard 
to get down), then jump up and over it, but land in front of sigma on the 
ground. The sicle will stab into the wall and make electricity shoot along the 
whole wall, don't touch it. Sigma will now land and jump back into the corner. 
Once he does that, you need to dash jump, or jump then hover at the highest 
point and go over to the wall behind sigma. Do this quickly because sigma lets 
out some old fashion evil laser eyes along the ground (thus the only safe place 
is in the air, where you can't be long enough, and on that back wall). Once 
here just wait for him to finish, he'll jump to the center of the room and 
retrieve his sicle. You can also hit him a few times: right after he lands from 
throwing the sicle to the wall; before he starts the laser eye attack, but once 
he's in the corner; as he jumps back to get the sicle; and finally, when he 
lands from getting the sicle.
  Remember to let out a charged shot AFTER he stops blinking from the hit 
before. Otherwise it really doesn't count. I will now list his attack pattern 
if you don't do what i said for his second attack (sicle combo), basically you 
DON'T WANT THIS AT ALL COSTS. It's better to take a hit and have the sicle 
stuck in the wall, then to dodge it and have it stab in the ground.
  3) sicle combo (bad version) - just listing this because it can happen, 
but i don't know any good way to avoid massive damage. If this does happen, 
just work on dodging, and forget attacking, I won't even list how to counter, 
just how to dodge. The sicle is now in the ground and so you can't land there, 
so you have the two walls and sigma in the middle near the ground. He'll now 
let out 4 real boom-a-rangs (this is like 'Outback Sigma' i guess lol), they'll 
float above him for a second then start, one by one, to come at you. Once they 
get to where you are, or were, they'll stop till all four have done this. Like 
any good boom-a-rang all four will come BACK at you to your new location. But 
this time not stopping and going off screen. This all doesn't sound THAT bad, 
but you have to try to dodge them while staying on the wall, in the air, and 
dodging sigma's big self too. Oh and don't forget you can't touch the ground. 
If this attack happens you WILL get hit, and it WON'T be fun.
  Once the second form is done get fall down the floor and walk to the 
life capsule and Alien Sigma will appear, next 2 forms up now....



++++Alien/Head Sigma [x4_as] ++++

OK the FINAL HUGE FORM of sigma. Since he has so many parts and so many attacks 
I'll just list them and how to dodge/counter the attacks. Also, there's Alien 
Sigma, Head Sigma, and 3 colored robot heads, I'll cover all 3 'forms' in the 
order they appear.
  Alien Sigma: his head is the part you must hit, if you played (or read 
his boss guide) as Zero, it's a different stragey here. He'll be in the top 
right corner of the room. He's got 2 attacks.
  1) "The end": he'll say it before he attacks to clue you in. It's a 
small laser that goes from wall to wall, only along the floor and once it 
disappears from his gun, the floor has a small explosion. just stay up on the 
floating heads on the left and let out a charged shot, you'll only get one 
here.
  2) multi shot: this time he'll stick around for a while. the yellow and 
blue heads kinda form a 'stair', just stand on the blue head and jump and let 
out a charged shot. once you get the timing of it down, you can make him shoot 
above you while you stand charging, then jump and hit him again, he'll just 
keep shooting above you (sucker). if that doesn't happen, or work out that 
well, just work on dodging the laser beam, it'll make a long triangle coming 
out of the gun, so the closeer you are to the gun, the easier it is to 
dodge....in a sense. With this attack, you should get quite a few shots off.
  If he does the second attack quite a bit, you'll defeat this form 
before the other. Also don't stay on the ground too much, as soon as he appears 
on screen just climb up the heads on the left side, either they'll help you 
dodge the only attack or help set up your multi-hit session. either way it's 
the way to go.
	
  Colored heads: ok 3 heads in the set, and you CAN destroy them, but it 
does you very little good because on the next "cycle" they all come back to 
life, so to speak. here they are in no particular order:
  Red head: it will appear on the left side and follow you vertically 
only, he will spew 4 sets of 4 fireballs. the yellow and blue heads are on the 
right. when u see him appear, or the blue and yellow appear, just stay on the 
ground until the first set gets close, then climp the heads on the right and 
get to the very top corner. the first to sets should pass below you quite 
easily. then drop down to the ground just behind the 2nd set. this will make 
the last 2 sets pass over you without worry.
  Blue head: possibly the easiest of the 3. it appears on the right side, 
red and yellow on the left, and spews ice frost to the ground. the key is to 
jump on top of his head. either double jump, or dash-jump off the red and 
yellow heads. just stand on top of him till they all disapper. just becareful 
not to fall onto any frost that hasn't disappeared yet.
  Yellow head: they hardest of the 3, but still able to dodge it all. 
this one will appear on the top, center of the room, red in the bottom left 
corner, blue: the bottom right corner. it now begins to launch electric spheres 
toward you, and when they hit a surface, you guessed it, they send out electric 
waves along the floor or wall. here's what to do: stand in the middle and as 
the first sphere comes at you, dash-jump to the left or right, landing on top 
of the head, then jump and cling once to the wall, and jump over the next 
sphere coming at you and you should be falling just in front of the 
next-to-last sphere. the last one will/should go towards the head or wall where 
u just came from and can either be dodged by standing still, or simply clinging 
onto the opposite wall as now his attacked would have stopped, and they begin 
to disappear. this can be tricky, but it's very possible to do this one w/o 
damage as well. 

  Head Sigma: No more x-buster here, whip out your "ground hunter" attack 
(you know, the one from Jet Stingray). Now it's kinda tricky how you have to 
hit him, but it's semi-easy. you need to jump and let it fall and hit him in 
the face area, if it hits him from running along the ground it's no damage, and 
if it's to high/far back no damage again. He's in the far left corner of the 
room, try to be in the far right corner of the room (just not touching the 
wall) before he fully appears. There's a 'visual' precursor for each attack, 
I'll also list them. Now here are his attacks:

  1) suck in: red head appears in the far right corner and the blue one 
in the middle of the room, they'll both have spikes on the left side of them. 
as soon as the appear, he'll suck you and debris in his mouth. Stand on the 
right of the blue head and just attack the debris flying from the right, it's 
hard to dodge this attack, and hard to hit him too. Once the 'sucking' is done, 
jump and dash to the top of the red head and climb, quickly, to the top right 
corner. Stay here to avoid all the debris. It's pointless to try to attack as 
the ground hunter will hit either the blue head or debris try to get to sigma. 
This attack is all about dodging.

  2) blow out: NOW is when you can attack. Someone said if you dash 
toward sigma when he appears he'll do this attack, I found he did the attack 
more often if I was standing very close to the right wall. All the heads will 
appear on the roof, and a wall of 'insta-death' spikes will appear all along 
the right wall. As soon as you see this, dash toward him and jump and let off a 
hunter. Then proceed to dash you heart away so you don't get blown into the 
spikes. You may not be able to get off a clean shot while he's blowing, but 
once he's done he'll pause for a few seconds which will give you a chance to 
hit him once or twice more.

  If you can avoid the debris when he does the 'suck in' attack, you 
should be pretty good. Make sure you have quite a few lives left and USE THEM! 
Don't go using your subtanks too early. "But there's full life tanks before I 
fight Sigma!"  Yes there are, but if you didn't notice, you will now, that 
they're only good to fill up your CURRENT life bar, NOT your subtanks. It will 
only fill an amount equal to a large life capsule in your subtank, so you will 
feel ROYALLY giped. So use your lives. If you feel the battle is going pretty 
good and you have the attack patterns down quite well then use a subtank. My 
personal advice, only use a subtank when 1 of the final forms of Sigma is dead 
(or VERY VERY close to being dead. And don't use one subtank, if you use one, 
then commit to the whole battle and use your second one when needed. If this
is your first time, don't get frustrated, just use a few lives and then a
subtank, trust me you'll save a lot of time. I really can't stress this point
enough.

**tkrausse says:**
I just discovered a useful tactic for Sigma's final form that you may want to
include.  When he does the head on the ground, always stay toward the right
wall. If he starts to blow, follow what your guide says, and Ground Hunter him.
However, if he decides to suck, being by the right wall should put you on the
opposite side of the Blue head from him. Now, if you have the Plasma shot arm
upgrade (not the multishot, but the plasma shot), you can shoot charged blasts
through the head, and into his mouth. The plasma has the added bonus of
destroying most of the debris that he spits back at you, making that section
much easier.  You might still take some damage, but probably less than I did
trying to dodge...

==============
Zero: [z4_bg]
==============

Playthru-- Web Spider >> Split Mushroom >> Magma Dragoon >> Cyber Peacock >> 
Storm Owl >> Frost Walrus >> Jet Stingray >> Slash Beast

Final Stage-- There really is no order at this point. You have all the
abilites you can get. Just go randomly or make some weird pattern, it won't
really matter. The biggest difference is that you should have all the sub-
tanks and heart tanks so that'll help. Other than that, no real difference.

Comments: Yes I have Magma Dragoon listed before Cyber Peacock for Zero and not 
for X because Cyber Peacock's weakness is Rising Flame Sword for Zero and Soul 
Body for X.

++++Web Spider [z4_ws] ++++

--Playthru-- Since u have no enhancements yet, this can be a little slower, and 
trickier, but still esstially pretty simple. He'll drop the the top, usually 
not low enough to hit u w/ his body if ur on the floor, he'll pause a second 
and then let a electric web go that will float ur way. You can jump and get a 
slash in before it fires a web. Two ways to doge these webs: 1) if ur on the 
left side of it when it fires one, dash to the right side, underneath the web 
and it will miss, just don't let it get too close, and 2) climb a wall, and 
jump over it towards the middle and it should miss. Those are easily dodged 
either way, just be wary of the timing of ur jumps, if u ARE caught in one, 
dash, jump, attack and move to get free, it will damage u while holding u in 
place. Once it has lost about half of it's life, it will come down in the 
middle of the screen and make a 4-wide web space to crawl all over. at this 
point he stops disappearing (yay!) but attacks more, and has a new attack 
(boo...sorta). now u have to be more careful not to run into it. it will still 
let out electric webs that can hold u in place, u have less of an area to move 
around in, but still pretty easily dodged. It's new attack: it will stop like 
it's going to let out a web, but it's "back/butt/whatever that thing is" will 
open and throw 4 mini-spiders up and onto the floor. they will land, and pause
for a second, now's ur chance to bash 'em, and then will either run left or
right, and up the walls till the disappear. Slightly tedious battle, but dodge 
those attacks and hit when there's an opening and u'll be good.

--Final stage-- Nothing much changes here, but his 'weakness' is your 'dash-
slash' attack. Unfortunatly there's no real use trying to use it as he stays
too high to attack him with it anyways. He's still easy tho.



++++Split Mushroom [z4_sm] ++++

--Playthru-- Weakess is naturally ur new electric thrust attack. there's two 
ways to do this, and i will explain both and why. if you get the timing down 
you can defeat him without taking a single hit. he will jump up to a wall and 
let off about 6 copies of himself, once all six hit the ground they take off in 
different directions and will hurt. the key is once the 5 once drops let off ur 
electic thrust, the sixth one will fall on it so don't worry about it. it u 
timed it right, ur saber will return as Split Mushroom drops to the ground. 
that's the plan. he'll now jump to the top of the center of the room and after 
a few seconds, SPLITS! (yes, hence his name) Now one will be slightly 
transparent as it falls to the ground, that's the fake one, don't hit that one. 
the other one, that was solid as he came to the ground, is the real him. now 
simply turn to him and hit w/ ur electric thrust. it will stun him for a second 
and then the two will jump and switch sides, just keep ur eye on the real one, 
and hit him again once he lands. they'll switch sides one more time and then 
the copy will disappear and he will start the "cloning" process all over again. 
simply lather, rinse, repeat as desired. yes it's that easy. if u do get hit, 
it's ok, it's very easy to get into the "timing" of things and finish him off 
w/o any more damage.

--Final Stage-- This time around it's pretty much the same, but w/ ur double 
jump and upgraded attack you can get him some hits when he first starts to make 
the clones, and also a hit or two in when he jumps to the very top and makes a 
copy. essentially follow the first guide above ^^ and you'll be done even
sooner w/ these new little tips. again, a very easy 'no damage' battle.



++++Magma Dragoon [z4_md] ++++

--Playthru-- In my opinion the hardest boss (aside from final sigma) in the 
game for zero. that's not to say it's not possible to beat him w/ minimal 
damage. he has no real weakness, ur new jumping attack will help w/ all battles 
in the future but it's no one's "real" weakness. the key to this battle is 
dodging his attacks, that's what i will explain, you will have to fight him to 
get the feel on how to run everything and do it all in battle. he doesn't have
THAT many attacks, but he exacutes them pretty quickly. I'll list them there w/ 
stratagies for each attack.
  1) the "hadooken" (a la Ryu and Ken), he will fire a high (head level) 
fire ball, or a low (ground level) fireball. he will also alternate between the 
two and can do up to 3 of them (just keep in mind that he won't repeat one of 
the same level back to back. so if he fires one high, the next will be low, or 
he may do another attack, but he will not do another high one RIGHT AFTER a 
high one, same goes for a low fireball). he usually did this while i was on the 
wall, and normally only did 2 of them, so once the first is done, jump and land 
right after the 2nd is launched and lay into him.
  2) fire jumping upcut (a la Ryu and Ken, again). he'll go a little 
forward as he goes up, so u can dash underneath him. careful as he will come 
back down rather fast. Lay into him w/ a combo as he comes down, or hit the 
jumping attack.
  3) lava fire. he will make a large ball above him and hurl it into the 
opposite side of the screen, it'll make the lava rise up so you cannot hang on 
the wall w/o some damage, plus the risk of falling into the lava and dying. in 
other words, avoide it like the plague. not much to do here, but if u can hit 
him while he holds the ball above him, do it, because he will pause for a 
second, leaving a big opening for a combo or so.
  4) firey jump kick. he will jump upwards and then comes down at an 
angle w/ a flaming jump kick. you can dash underneath it, but that can be hard, 
or dash away from him. caution, this is a very quick attack. if u can see it 
coming jump attack him or hit a combo as he lands, carful to not be too close 
or u'll get hit.
  5) fire breath. this is a long attack, but u'll see it coming a mile 
away. he goes to the edge of the platform and faces the opposite side. then he 
flashes red and opens his mouth. at this point go climb the wall that he's 
facing toward and scale it upwards. wait till u can see him again, he has the 
tendency to do this attack back to back, so be careful. a great counter attack 
for this is jumping behind him. you can jump on the wall behind him and attack 
or stand on the ledge behind him. there looks like there's no room, but you can 
actually stand there w/o being hurt. so do that and lay a combo or 2 into him.
Last note, watch the small lava pits, that spells instant death. Also just keep 
dogding and attacking, just make sure to do the jump attack or 3 hit combo, 
don't wanna waste ur hits. 

--Final Level-- This time around it's easier to get behind him, hang on the
wall and wail on him. The more hits you can get on him being on the wall, the
easier this battle will be.


This FAQ should only be found on www.gamefaqs.com or www.supercheats.com.


++++Cyber Peacock [z4_cp] ++++

--Playthru-- Well u just got his weakness from Magma Dragoon: rising fire 
attack. This is another possible "no damage" battle. He will teleport 
everywhere on the screen, but there's an easy pattern to it. he will pause a 
second (while invisable) and appear at ur location, so as to damage you. but if 
you dash while he is invisable he'll likely appear behind you. the tricky part 
here is u need to turn around and hit him w/ the rising fire attack quickly 
before he lets off his attack. his 2 attacks when on the ground are: 1) 
feathers spread out in a 180 degree shape: the feathers will then stab outward, 
but will only hit if ur close enough, and because of the speed of this attack, 
you usually are. 2) feathers spread upward and downward: he will jump into the 
air and disappear again. pretty simple to dodge those attacks, but it can be 
tricky to turn and hit him w/ rising fire. the other chance you have to hit him 
is when he appears on the either side of the room, by the wall about midway up 
in the air. this is a VERY easy time to hit him w/ the rising fire attack. 

*NOTE* everytime he is hit w/ rising fire, it will "disrupt" him and cause him 
to stop what he's doing and disappear again. *end note*

--Final Stage-- None of your upgrades/abilites help here because it's mostly
reaction anyways.



++++Storm Owl [z4_so] ++++

--Playthru-- Use newly aquired weakness: giga attack. This is really the only 
"good" use of this new attack. There is a downside to it tho, there's only 4 
attacks to a full bar, the good side is that when u take damage it fills up 
some. So as u guessed it, this cannot be a "no damage" boss battle, but close 
to it. If you hit him w/ anything but giga attack, he'll get a green 'sheild' 
around him, and tends to counter attack when u do this w/ green orbs. try to 
let him get close, or dash to him before using the giga attack, it should take 
5-6 attacks to beat him but be careful because those green orbs can block the 
giga attack from hitting him. his attacks and ur counter attacks to them are as 
follows:
  1) he will stand or hover in one of the 4 corners of the room and let 
out 4 green orbs, one at a time, they seem to go to random locations but after
they all get there he will take off across the screen and leave, but once he 
starts moving so do the orbs, they will come after you. very tough to dodge, 
and they're invincable, just do ur best. do NOT giga attack now, u'll usually 
waste it, and there's no need to try.
  2) he will stand on the left or right side and make 3 tornados appear 
around, and on, you. you can see them forming below you before they actually 
hit, so you can dodge out of the way pretty easily. this is a pretty good time 
to hit him w/ a giga attack, just make sure to be near him.
  3) he'll fly in on the left or right and fly slowly to the other side 
of the screen, usually go back and forth if u don't attack. if you jump, or use 
rising fire on him now, he'll swoop down and grab you, then slam u into the 
ground, then he'll fly off. this is a good time to use the giga attack. in fact 
this is the most times i use it, because he's moving, and when he moves he 
doesn't attack.
  When you hit him w/ the giga attack he flashes black and white patterns and
then flys off. this is stop any attack he has going and also makes him fly off 
so he doesn't do any attack till he flys back.

--Final Stage-- Naturally not much has changed, same tactic as before but now
you should have the weapon tank, so you actually do this with minimal damage.



++++Frost Walrus [z4_fw] ++++

--Playthru-- Weakness: rising fire (naturally). pretty simple fight here as the 
rising fire will make him lose his "ice teeth" and toss him to the ground. but 
once he is on the ground (kinda looks like he's crouching) he'll slowly slide 
across the room at you till he hits the wall. it's not to fast to dodge, but 
he's so big and long you need to time ur jump. just hang on the wall and wait 
for him to nearly hit it, then dash-jump off of it and land on his other side. 
he'll then stand up, 're-freeze' himself and begin walking at you again. as 
soon as he starts to move once his teeth are back, use rising fire again. 
lather, rinse, and repeat till he has half life.
  Once at half life he begins a new attack pattern, he will now (after you
'fire' him) blow freezing cold air and form a large icicle, it will drop in
front of him and shatter into smaller icicles, but these ones will nearly cover
the screen. you can either dash to the other side of the room to avoid them, or 
just jump attack to easily destroy them. then dash back to him and use rising 
fire again. rinse, lather, repeat until he bits the ice (as opossed to 'dust'). 
Once again a very possible "no damage" battle.

--Final Stage-- Not much has changed but you may avoid his dashing attack
easier w/ the air dash move.



++++Jet Stingray [z4_js] ++++

--Playthru-- Weakness: Ice stab. Once you know how to fight him, it's simple 
and quick, but getting there can be a little tricky. First off know that there 
is a "sweet spot" it's right up against the wall, both sides of the room. the 
thing that makes it sweet is you can hit him w/ ice stab even before he lets 
off any attack. the key is to be on the same side as him. now when u first 
start the battle he usually slowly hovers down to water level and then jets 
under and over across the room, coming upard when he get to the other side. 
it's easy to try to hit him when he does this, but just focus on getting to the 
sweet spot first. when he does that swoop across the room, he'll come down from 
the side he flew towards. go to that side of the room before he comes down. 
make sure ur pressed up against the wall and when u see him coming down double 
jump and ice stab him. it will freeze him for a second, then he'll break it and 
fly upwards. he ususally comes back down on the same side, so simply repeat 
until he's done. if you do it well enough he won't ever get an attack off. 
since that IS tricky i'll list his attacks and how to counter them.
  1) room swoop. he will hover for just a second above water and then 
swoop down and across the room. if ur on the opposite end of the room from him, 
you can time it and ice stab him mid-flight, just don't be over him when he 
breaks the ice or he'll hurt u.
  2) blue mini-rays. he will hover at water level and let out 4 mini-rays 
that will go across the water, down the wall, and across the floor. a jumping 
attack will defeat them easily. but as soon as he lets out the 4th one he does 
a room swoop. so watch out. 
  3) red mini-rays. same as blue ones but they will not wait for the wall 
before they come down, they will come down whenever they get above you. so you 
cannot dash underneath them. he will still room swoop after the 4th one of 
these as well.
  4) vertical dash. he usually does this very late (ie: low on life), if 
he does it at all. if you flowed my first stratagey you may never know he has 
this attack. he will dash (like after he breaks the ice) downward, and then 
almost immediatly, upward. just dash from one side to the other, try not to 
"back track" over ur own dashes to quickly or he may be rising right behind 
you. don't try to ice stab him here either, it's nearly impossible.

--Final Stage-- once again not much change, you should be used to ur double 
jump and attacking more now, so that may make the "sweet spot" stratagey 
easier. Just to let you know, once i found out how to do that 'sweet spot' it 
became a "no damage" battle for me. just be quick in hitting him, try to hit 
him high above the water, and you'll have no problem.



++++Slash Beast [z4_sb] ++++

--Playthru-- no real weakness. this battle CAN be a "no damage" one, but that's 
more dependent on him, not you. Since there is no real weakness i'll list his 
attacks, and how you counter them.
  1) growl. or what i like to call his "bark". >_< He will simply stand 
and bark at you, doing nothing more. it's not a set up, or precursor to any 
move, it's just there, possbily because the developers wanted him to 
sound....well stupid. while he does this just lay into him, best bet is either 
jumping attacks or 3 hit combos. 
  2) air slash. it's 2 green slashes, medium size, that go across the 
room. one i horizontal at about head level, the other is at an angle upward 
diagnally. He reminds me of Guile in street fighter w/ the flash kick move. 
it's done VERY quickly, and since zero is so close when attacking it's very 
hard to avoid this move. you cannot dash underneath it, and u have to double 
jump over it, just be careful not to jump too high and hit the 2nd one. this is 
the attack that will determine if you get "no damage" or not.
  3) slash dash. he will lift his hand, and it will have a purple-ish 
"star" flashing. then he will dash to one wall, pause, then dash to the other 
wall all while slashing low to the ground w/ that flashing hand. it's very easy 
to dodge, just dash-jump/jump dash over him; or cling to a wall and wait for 
him to finish. if you're quick enough you can sneak in a few hits while he's 
dashing. 
  4) claw jump. he will jump to right above you, and then slash downward 
w/ his claws. quite easy to dodge really, often times he'll do this twice in a 
row. another attack easily dodge and countered.
He will also jump to the far end of the room, this can also be confused as the 
"claw jump" if ur standing near the edges. What makes this a possible "no 
damage" battle is all dependent on HIM not YOU. his air slash is VERY hard to 
dodge if you're on the offensive, and as zero, u usually are. you should be 
able to dodge all of the other attacks w/ very little difficulty. Overall not a 
hard battle tho. 

--Final Stage-- not much has changed, you only have all heart tanks and
subtanks now (or should have them) but nothing really to help w/ the battle.
Just hit him hard, and fast and you may be able to beat him before he uses the 
air slash much.



++++General Tips for the final stage [z4_gt] ++++
This tip is for before the 'Final Stage' meaning the bosses again too. If 
you're having massive trouble beating the Final Sigma form heed this advise: go 
to Snowy Base and fill all your subtanks and get all 9 lives up. Don't use any 
subtanks until you're on the last form of Sigma. If you're having trouble 
timing things or just getting the 'feel' of some things, use some of those 
lives before you use a subtank. The "full energy" capsule before Reaper Sigma 
will NOT fill up a subtank (not sure if that's a glitch or the way it's 
supposed to be). So ONLY use a subtank if you're on your last life or pretty 
certain you will beat him.


++++Reaper Sigma [z4_rs] ++++

simple. a very easy "no damage" battle. just stand there, and when he appears 
use rising fire. he'll do that twice, once you hit him for the second time go 
climb a wall, any wall at all. he will appear on the oppsite side of you and 
slash across the room w/ his sicle. now just jump-dash/dash-jump over him as he 
crosses the room. **note** if you HAPPEN to be on the ground when he slashes, 
you can jump over the flashing sicle and thru the bar of it. that can be risky, 
and it's easy to climb the wall, so i don't advise it. **end note** Do that 
about 4 times (a pair each time) and he'll go down.



++++Sigma [z4_sg] ++++

This is a tough/tricky battle but can be easy w/ good timing. Try your best to 
not use a subtank, it'll be highly needed for the final battle. He will start 
by jumping and throwing his sicle like a boomarang, it will go to the wall, 
come down and slightly below and behind him, then return. you can get a jumping 
attack in before he throws it, and usually before it returns, but it's 
important to dodge above all. he will then turn to whatever side you are on and 
jump again, this time the sickle will get lodged into the wall or floor, it all 
depends on where you are. he throws the sickle this time at you, so if ur on 
the ground it will go there, if ur in the air or on the wall there's a good 
chance it will go there. the trick is to be slightly high in the air when he's 
ready to throw, best thing to do is hang on the wall and when u see him throw 
it jump over it onto the floor, but land in front of Sigma. Here's why: if it 
lodges into the wall it will send out electric waves along that side, and sigma 
will jump to the opposite corner and begin to shoot out lasers from his eyes 
along the ground. the key here is to jump over sigma and slide down the wall 
and when ur low enough slash him. don't worry there's room to slash and then 
jump back up along the wall and slash again. you won't take a single hit doing 
this, unless u jumped too low getting to the wall. once he's done w/ the lasers 
he will jump back to the center of the room, get his sickle and repeat. not too 
bad eh?  if the sickle gets lodged into the floor, however, this is going to 
be ROUGH. Sigma will land on the floor and let out 4 boomarangs (they really
look like they're from the land down under too) they will hover above sigma for
a second and then, one by one, come towards you. they will go towards you and 
stop, until they are all out. then they will come at you AGAIN, this time not 
stopping, but disappearing. you can receive quite a bit of damage if this 
happens. just dash, jump, do whatever you can to avoid the 'rangs. while ur 
jumping around, you can take a few hits at sigma. that's really all there is to 
it. make sure to get the sickle lodged in the wall and it will be MUCH easier, 
and possibly a "no damage" battle. :D  Good luck.



++++Alien/Head Sigma [z4_as] ++++

Hardest battle of the game. there is no weaknesses to speak of, only tactics. 
This is a 2 part boss, that means 2 life gauges to empty. very long and 
difficult. it's BEST to have both subtanks for this battle. Yay! you get a 
energy pill before this battle starts, just a comalation prize really. Since 
there's actually 5 parts to this boss i'll list them, their attacks, and 
tactics below. keep in mind that the colored heads can be "beaten" but will 
regenerate like they were never beaten in the first place. Here is the overall 
pattern: colored head --> sigma head --> colored head --> alien sigma --> back 
to colored head. when Sigma head or Alien Sigma is beaten, the pattern is 
shorter (i'll use sigma head for the example): colored head --> sigma head --> 
back to colored head. Ok now i'll break down their patterns:

  Red head: it will appear on the left side and follow you vertically 
only, he will spew 4 sets of 4 fireballs. the yellow and blue heads are on the 
right. when u see him appear, or the blue and yellow appear, just stay on the 
ground until the first set gets close, then climp the heads on the right and 
get to the very top corner. the first to sets should pass below you quite 
easily. then drop down to the ground just behind the 2nd set. this will make 
the last 2 sets pass over you without worry.

  Blue head: possibly the easiest of the 3. it appears on the right side, 
red and yellow on the left, and spews ice frost to the ground. the key is to 
jump on top of his head. either double jump, or dash-jump off the red and 
yellow heads. just stand on top of him till they all disapper. just becareful 
not to fall onto any frost that hasn't disappeared yet.

  Yellow head: they hardest of the 3, but still able to dodge it all. 
this one will appear on the top, center of the room, red in the bottom left 
corner, blue: the bottom right corner. it now begins to launch electric spheres 
toward you, and when they hit a surface, you guessed it, they send out electric 
waves along the floor or wall. here's what to do: stand in the middle and as 
the first sphere comes at you, dash-jump to the left or right, landing on top 
of the head, then jump and cling once to the wall, and jump over the next 
sphere coming at you and you should be falling just in front of the 
next-to-last sphere. the last one will/should go towards the head or wall where 
u just came from and can either be dodged by standing still, or simply clinging 
onto the opposite wall as now his attacked would have stopped, and they begin 
to disappear. this can be tricky, but it's very possible to do this one w/o 
damage as well.

  Alien Sigma: i list this one first b/c it's eaiser than the final form. 
when you see/know he's coming jump and cling to the top left wall (on the 
yellow head when it comes out from the wall) and wait to see which of the 2 
attacks he does.
  1) he will appear for a second, and then the 3 heads will come in, the 
blue and yellow on the left and red on the bottom right. if the blue and yellow 
form a flat wall, he'll say "the end!" and shoot a laser beam along the whole 
ground. just jump and cling to the top corner on the left, on the yellow head. 
he will disappear after this, which leaves no real chance to hit him.
  2) this one the blue head will be closer than the yellow head toward 
the middle. making a raised platform. this will be the "open a can of fire 
fury" on him time. now he'll let out a triangular shaped laser out of his gun. 
all you need to do to avoid this stand JUST under the gun to the right of the 
laser beam. now let out ur rising fire attack. it should hit, and possibly 
destroy the red head, which has spikes sticking out so don't get too close. 
near the top of ur jump u'll start nailing the head area, which is the only 
area that can be harmed. land, move back to the left some (under the gun) and 
let it off again. in one round of this you should be able to get about 1/3 of 
his life off. in other words, 3 times of seeing this pattern, and he's done.


  Sigma Head: Now for the REAL hard stuff. here's a pre-stratagey, when 
he appears, and before the heads do, you should be on the right side of the 
room, and dash toward him. that CAN make him use attack #1, which is GOOD for 2 
reasons: you won't get damaged, and you can damage him. the 2nd attack is 
basically the opposite of that.
  1) the wall on the right will turn into spikes and the blue and yellow 
heads will drop down and hang on the ceiling while the red head will be in the 
top left corner of the room. now almost as soon as the heads appear, he'll 
start blowing wind, really powerful wind that if you continue to dash you won't 
get too far, but you won't really be pushes back either. the key here is to 
continue to dash and stay close to his head and use ur dash slash attack. hit 
dash and near the end of it's "dashing" hit triangle (or w/e you set ur 
'special attack button' to) and hit him. you should be able to hit about 3 of 
those. then he'll stop blowing but not disappear yet. this is ur chance to open 
up a 3 hit combo or jumping attack. if ur quick u can nail 2 jumping attacks 
before he disappears again. remember while he's flashing from damage, he won't 
take any more damage till he's done flashing so ur electirc saber thrust 
totally sucks.
  2) this is the attack you DON'T want. he will begin to suck in debris 
and you. the backfire to dash at him is that he could do this attack and you'll 
get stuck in his mouth. so the debris WILL damage at this point. as he starts 
to suck things in, the red head will pop up on the botton right corner w/ 
spikes sticking out of the left side of it. and the blue head will pop up in 
the middle of the room, on the bottom, just left from the red head, w/ spikes 
on it's left side. you can easily use the blue head for protection for being 
sucked in, but the hard part is destroying all the debris flying at you. once 
he's done sucking he will pause for a QUICK second, u can use this time to 
double jump on the red head and climb to the top of the right wall. if you stay 
in the top right corner no debris will hit you, but be carful jumpin up there, 
it's easy to get hit by the red head's spikes. this attack is also bad because 
you have to worry so much about being hit, that you simply can't damage him. 
trying to destroy all the debris that is coming at you is insanly hard, just 
jump to the corner like i said and wait for the next round to try to get him to 
do the first attack.

If you can avoid the debris when he does the 'suck in' attack, you should be 
pretty good. Make sure you have quite a few lives left and USE THEM! Don't go 
using your subtanks too early. "But there's full life tanks before I fight 
Sigma!"  Yes there are, but if you didn't notice, you will now, that they're 
only good to fill up your CURRENT life bar, NOT your subtanks. It will only 
fill an amount equal to a large life capsule in your subtank, so you will feel 
ROYALLY giped. So use your lives. If you feel the battle is going pretty good 
and you have the attack patterns down quite well then use a subtank. My 
personal advice, only use a subtank when 1 of the final forms of Sigma is dead 
(or VERY VERY close to being dead. And don't use one subtank, if you use one, 
then commit to the whole battle and use your second one when needed. If this is 
your first time, don't get frustrated, just use a few lives and then a subtank, 
trust me you'll save a lot of time. I really can't stress this point enough.



====Secrets [scts] ====

Zero's Black Armor (confirmed)--at character select screen hold R1, press Right 
6 times, release R1, hold in O, and press start.

Ultimate Armor for X (unconfirmed)--at character select screen press O twice, 
left 6 times, hold L1 and R2 till you start the first level (press start to 
begin). Then once you beat the intro level, go to the Jungle stage and find the 
leg upgrade to give you the full armor.

Easy Subtank refill and extra lives--Once you have the Double Jump or Air dash 
(possibly done w/ just a wall-dash), go to Snowy Base stage, right at the start 
of the level either take the left wall up and jump over to the right wall, OR 
double jump to the right wall and take that up. there's a mini path up there w/ 
a couple of small snowmen baddies, and a big ape baddie, along w/ several 
energy tanks, a few weapon tanks, and a 1-up. once you clear that area (and the 
boss) don't jump down, just exit the level and rinse, lather and repeat as 
nessicary. 




====Final Thoughts [flth] ====

I saw there was no boss guide for X4, and I just got the MegaManX collection,
so I thought I'd help out. This is also my first walkthru, so don't nit-pick 
TOO much. Please contact me if there is a glaring problem and I will fix it, 
but if it's somthing that can easily be overlooked, don't worry about it. I'd 
be REALLY nice to get positive feedback, so please if you liked this and found 
it helpful, lemme know. Hopefully you can enjoy the X series like I did/do. I 
look to do a few more in the future, hope ya'll enjoyed the ride!  Laterz.


====Thanks/Credits [crds] ====
