Leader of the Caligars—a reptilian race living in Subternia—Ceratus defended his homeland against former allies Lord Dactys and the Speleans. Fiercely strong, he fought with a unique bone club, throwing blades, and his spiked tail. He harbored a deep hatred for another Caligar, Whiplash, whom he regarded as a traitor. Ceratus joined other leaders as part of the Eternian Council at the Royal Palace.

Classics bio
Shortly after the Great Unrest ended the Caligars and Speleans returned to their kingdoms to find their homes had been destroyed while they fought with Miro on the overside. Blaming each other for the destruction, both species were plunged into a war that would continue to ravage their kingdoms for decades. It was not until the threat of Skeletor and King Hssss emerged that Ceratus, leader of the Caligars, put aside his differences with the Speleans and joined Randor's new Eternian Council. In addition to serving in this political group, Ceratus also fought as a member of the Masters of the Universe during the Second Ultimate Battle Ground. Leading a battalion of Caligar warriors, Ceratus fights for the freedom of Eternia.
