The Wii Fit trainer being in the game is garbage.
at Olimar returning. Never liked him.
In addition to Bowser Jr and Waluigi, I would like to see Toon Zelda in the game and similar to how regular Zelda can transform into Sheik, I would like Toon Zelda to have the ability to transform into Tetra.
Would be awesome. And I only recently just found out that Toon Zelda was going to be planned to be in Brawl along with some other characters but was cut: http://super-smash-bros.wikia.com/wiki/Unfinished_Code
