The leader of Third Earth's tribe of Berbils, Ro-Ber Bill acts both as a gentle authority figure and the spokesperson for his people when interacting with the other races on the Berbils' adopted planet. Ro-Ber Bill is possessed of a typical personality for a Berbil, being friendly, generous, thoughtful and reliable. Like all Berbils, Ro-Ber Bill is clever and hard working, and is always a firm friend to the ThunderCats in times of need.
