So if Awakening gets a rep, I was thinking that to represent the game, Chrom and Lucina would both get in, but paired up. However the FE board gave me an idea on how that could work. One character is playable at a time but can switch around not unlike the Ice Climbers. Also it took a lot of work to not make them clones of each other or Marth or Ike.
Chrom draws from his class trees for his move set
B Bowfaire: representing his archer class tree, Chrom pulls out a bow and fires an arrow. Unlike Link's it is not charged and it flies straight. However there is a delay to pull out the arrow.
Side B Aegis: represents his cavalier tree. Chrom pulls out a lance that absorbs all damage from projectile attacks.
Up B: Aether: represents his lord tree. On the ground it is a slash upward that restores a bit of health while following up with a charge that deals major damage and breaks shields. No knock back and slow but powerful.
Down B: Dual Guard: Usable only on ground. Lucina jumps out of the background and guards an attack while Chrom jumps into it.
Lucina draws her move set from her potential mother's skills
B Galeforce: represents Sumia. Fires a weak but fast moving fireball that if it connects, Lucina quickly pulls out a lance, and warps to the enemy for a strong attack.
Side B: Renewal: represents Maribelle. A strong but slow slash with an ax. Heals 30 percent if opponent is KOed
Up B: Luna: represents Sully. Pulls out a lance and charges dealing major damage with no knock back and breaks shields. A forward charge on the ground, upward in the air.
DownB: same as Chrom.
Final Smash: Dual Strike: Current character uses Aether on the opponent while the other does a leaping critical hit almost guaranteed a KO.
And how would you switch between them?
It's the down B that switches
Aaaah, got it. I thought it was just a simple block, or something.
Overall the moveset is solid as far as the attacks themselves go, but some of the effects seem to me as if they'd be overpowered, though I might be misunderstanding your intention. Even without my criticisms being addressed I'd give it a 6/10, possibly more if you clarified any point that I maybe misunderstood.
Final SSB4 prediction/wishlist before E3 2013
But it says not unlike the Ice Climbers. Thus it's like the Ice Climbers. They can't switch their leader mid match. Other than that, I do think this seems like a pretty good idea, but Chrom + The Avatar seems more likely and could do a lot more interesting things IMO.
Palutena, Isaac, Ridley, King K. Rool, and Anna for SSB4
