Berbils (also known as Ro-Bear Berbils) are a band of small robotic bears from the planet Ro-Bear. They crash-landed on Third Earth a long time ago and now live in the village of Berbils. They produce a variety of Berbil fruits including meat fruit, bread fruit, veggie fruit, and candy fruit that help feed the Thundercats and other Third Earth inhabitants. The Berbils helped the Thundercats to build the Cats' Lair. Their elder is Ro-Bear-Bill.
