Charizard!

[Dark Jaguar]

Did you see the latest Nintendo Direct? Behold all their majesties.

We got Yoshi back, we got Zero Suit Samus and Sheik. Charizard's in there, and so is newcomer Greninja.

So what else is new? They've officially ditched the concept of "multiple characters in one". The basic idea is to make things a bit less complicated than they were starting to get, with the need to switch between movesets and playstyles mid fight all the time. Zelda and Sheik have been split into two characters, as have Samus and Zero Suit Samus. This frees up their Down+B specials to be new moves.

As for Pokemon Trainer, it appears there's been a sacrifice. Charizard has gotten too rebellious and struck out on its own, leaving the trainer (and Squirtle and Ivysaur) behind (as opposed to make those two unique characters as well).

There's also some other new Pokemon character. How many Pokemons will this game have...

Otherwise, when playing as Zelda/Sheik I usually would stick with one through each match, but removing the option of switching is kind of unfortunate; it removes some strategy. Having one more move each should be nice, though. Another reason they might have done that, though, is because it lets them "increase" the character count without actually doing anything... :p

As for replacing the Pokemon Trainer with Charizard... eh, why not. Charizard is one of the better Pokemons anyway.
