Character Design: His name was chosen poorly, but this is due to the translation of the game rather than the actual character design. And he's a mushroom man...I don't recall ever seeing such a design in any other game, making him rather unique.
Combat Usefulness: Having never really used him, I cannot say.
Tilt: He's a mushroom man! But, thing is, he's just a random character. He just changes because you give him a mushroom. He has no purpose in the game other than to be there.
Now if he'd been given a purpose, he'd be more interesting, but without it...
Final Grade: D.
