Characters:
Isaac: The guy is cool and he has Synergy. Perfect for Smash. If he does get in they better not make him anoher damn sword user.
Krystal: Not a furry or anything, she deserves it. StarFox got hit in the groin in this game, so yeah Krystal would be cool. It's obvious they axed Wolf inmediately so I won't try. But if they make Krystal another fastfalling blaster wielding speed side b fire up b reflector wielding character I'm going to Japan to kill those fools who though it was a good idea.
K Rool: this game gives an entire disrespect to all heavy weights by not having a single heavyweight newcomer. Plus, K Rool has a lot of options for a moveset.
Mewtwo is in.
Ice Climber: That right Ice Climber, being a Olimar-Alph dinamic with Popo and Nana, a single climber with no stupid gimmicks, good moveset and no chaingrabs. Done.
And yes, I don't support Squirtle, Ivysaur, Roy, Wolf, or Lucas. They were surely ditched inmediately. Neutral towards Bandana Dee and Impa.
Stages:
Fountain of Dreams, Dreamland64, Hyrule Castle64, Saffron City, Pokemon Stadium Melee, Pokefloats, Fourside, Yoshi's Island Melee, and Meta Krystal64(even though is what not playable and P:M did it already).
