Catbug is a creature who is half cat and half ladybug. He has a very childish personality and exists in two dimensions, the "normal" dimension and the See-Through Zone, a place where the Courageous Battlers where imprisoned. He is the show's breakout character.
When Beth was shifting through dimensions in the episode, "Hammer Priest", one of the dimensions was a universe ruled by Catbug. He is very rude and demanding and likes to drink from his mug called "Big O'l Beer".
