Along with other Berbils forced to leave the tiny planet Ro-Bear behind in order for their race to expand and survive, Ro-Ber Bob and his shipmate Ro-Ber Bert are resourceful and clever, having had to learn to survive on a remote island on Third Earth along with the "new" ThunderCats. It is not known exactly what became of the two Berbils when Lynx-O, Bengali and Pumyra joined the other ThunderCats, but it is assumed that they rejoined their fellow countrymen in the Berbil Village on Third Earth.
