Word to the wise, never go up against Tien in a Tien/Krillen argument. There is
no way to win.
But I'd like to say that Kid Buu never really used his maximum potential against anyone, if he had then Goku and Vegeta would have been screwed.
As it was Kid Buu just played with Krillen for a few seconds before letting him go, with Tien the other Buu used enough energy to knock him out for good.
Anyway, to stay on topic, do Oolong and Puar really count as human? I mean ones a cat and the others a pig. Besides for that Master Roshi was stronger than both of them put together.
(**waves Krillen flag** Go Krillen!)
