I think most people that have sen DB hated Krillin from the beginning
And obviously, all characters are below Popo. That just goes without saying. I mean, even in canon, he was taking attacks from Super Saiyan Goten and Trunks when he was trying to keep them from leaving the tower during the Buu Saga. Kinda makes you wonder why he just didn't go and beat Frieza himself... I mean, he is immortal, right?
