Mewtwo is the obvious choice Unfortunately the developers choice is Lucario on the other hand it would be cool to see a non humanoid pokemon show as a playble charecter imagine Tyranitar, Gengar.... . .. ... .... ..... ...... ....... ........ ......... !!!!!!!!! we must have Gengar! Gengar! I vote Gengar all hail the king of ghosts the titan of competitive the sweeper of ages! physical moves (a moves)could be based on shadow punch shadow claw, poison jab sucker punch etc all could provide inspiration for the ghosts techniques. for special moves (b moves) shadow ball(b) sludge bomb shadow ball focus blast dazzling gleam... it has so many options!
and the mega adds an obvious smash trap and eliminate style...
Anyone wonder how Zoroark's Illusion mechanics would translate into a fighting game? I mean, straight up taking the image of another fighter wouldn't really do anything (the point of Illusion is to get the foe to hit Zoroark with something that won't kill him. No one is going to hit Zoroark with a different move just because people think he's Captain Falcon), but would that mean... shadow cloning? Or something?
Although, even if he was done right, he'd probably still be used as a punching bag for Lucario players.
Characters i hate but know would get put in: Salamance garchomp mewtwo again lucario again charizard again plus mega blaziken plus mega
others that would fit: Lopunny (type wild) Gardevoir plus mega (popularity *sigh* and type wild) Gallade Gengar (type wild and ghost enhancement) Sawk and Thro The hitmons any of the starters Mew victini
