Wow, that Metroid item would be cool. You could pick up a containment test tube thing w/ a Metroid in it and it could go and suck the life out of other players! For characters, they need to add Megaman, Banjo and Kazooie (not going to happen now), Sonic, Tails, Knuckles, Wario, and a Waluigi clone of him (like Mario and Luigi are in the game), a realistic and cel-shaded version of Link, Samurai Goroh, Baby Bowser, Mr. Resetti, Captain Olimar, and Star Wolf. Thats all I can think of now.
