This is pretty much how I feel towards the majority of SSF2's newcomers. It's much like how many fan movesets try to cram as many references as possible without actually thinking of what the move's purpose is.
Isaac doesn't really have a theme sticking his jumbled mess of moves together, his tilts are specially bad.
Mega Man has a terrible weapom switching gimmicky and his merging of the Smash Mega Man didn't help him at all.
Black Mage has the same issues as Isaac, all of his specials are useless too.
This applies to pretty much everyone in the roster except Bomberman and, ironically, the anime characters.
Bomberman's moveset is simple yet effective, nothing in it feels out of place.
The anime characters probably work so well because most pf their moves are taken from official games but at least they have themes for their movesets: Naruto has his clones, Luffy is his big time range and Goku has whatever Goku does.
And Ichigo, who is "big sword with flash steps", is easily my favorite character in that entire game despite me never having watched or read Bleach.
Moral of the story? McLeodGaming should just make an anime Smash fangame.
