Yeah, its sort of a let down. Unless the frail looking body is just a kind of metamorphasis. When he's giving out his Charka kind of like Choji at high levels he loses weight. But then after the recievers (or the opposite) are removed he looks normal. I hope that is the case and he is kickass fighter. But i was right about the tower thing and how they would figure it out. Would have been nicer to be wrong at this point tho.
