#1: I don't think it's really fair to say the original, since, you know, pretty much every major Nintendo protagonist to have a game in their series released at that point was in, obviously it wins. Outside of that, I'll go Wii U/3DS, Brawl, then Melee. Brawl would be ahead were it not for Meta Knight.
#2: Again, original's a bit unfair to do it on since it was the first...
Melee: Mewtwo, Ice Climbers, Zelda
Brawl: ZSS, Ike, King Dedede
Wii U/3DS: Robin, Villager, Greninja. I'd love to put Lucina on there but no points for being a Marth clone.
#3: I'll go ZSS, since she was my main in Brawl and will probably be my main again for Wii U/3DS. Ton of fun to play with once you get the gist of her playstyle. Has a couple of terrible MUs that are no fun at all (Falco blargh), but outside of those she's an absolute blast.
