Unta Mathos was a Jeridian. Her home world became more warlike in answer to the Monaxi threat. She fought against the Monaxi along with Mem-Brain, Sunzberro, Tony and Effrid Blunk, their leader, for a long time. (COMIC: Medicine Man)

Unta was one of the people transported into the Arena of Fear by a time bridge. She was under Ebonite's control and attacked the Tenth Doctor and the rest of his group, but was freed when Ebonite was defeated. She continued travelling with Effrid's group afterwards. (COMIC: Arena of Fear)
