One of my favorite parts of Kabuto was his fighting style. He just gave off an aura that gave you the feeling that he can't be messed with and if you tried, he'd beat your ass as if it were nothing. But with Kiva, I still don't see Wataru being in that suit since he's so small and the mannerisms come out of nowhere.
Kamen Rider Watermelon? Some jackasses from RB must have come up with a retarded name like that.
