Perhaps to drive a more in depth story, and to really feel like a "Legend". Perhaps a big battle with it, but made to not be able to be caught. Almost solely like a boss. Make it super over powered and make it the one Pokemon out of our grasps?
I doubt this will ever happen, but how would you feel if it happened? --- 3DS : 2079-6838-1883
I wouldn't mind one that you couldn't catch first time and had to return post game to get.
Like Dialga, in P:MD Sky.
Or Black/White Kyurem in B2/W2.
But no. Just no. They just brought back the "Gotta Catch 'em All!" slogan, they're not gonna pull a stunt like that. --- http://pokefarm.org/_ext/user/110trainer#0 http://www.fanfiction.net/s/9247960/1/404-Error http://imageshack.us/a/img189/1407/jh6l.gif
You'd have to be able to get it eventually? Otherwise, the whole premise of "Gotta Catch 'em All" would be moot if there is one you can't actually never catch. --- Donnel is my # 1 bro. We fist bump, slay some risen, eat some chicken strips, bomb the Valmese and steal sugar from Gaius on a daily basis. Like a Boss. FE:A
Maybe not uncatchable, but make it so you fight it once, and can't catch it then. It runs off after the fight. In order to catch it, you have to beat the Elite 4, catch the minor trio of the land (like the Lake Guardian trio, or Legendary Cat trio) go to a tower of some kind, reach the top, getting a special item at the top, then fight your way through a post game cave to a special room.
Only there can you use the item with the trio in your party to summon the Legendary.
Not uncatchable, but certainly very difficult to do, a quest worthy of catching a Legendary.
