Tauras

Tauras, also known as Rexasalonolan (Rexx for short), was a Time Lord and one of the Adherents of Ohm, a secret society that worshipped Omega. Eventually, he gave up his body to be taken over by Omega himself.

Omega, posing as Tauras, became Adjutant Coordinator of the Celestial Intervention Agency. (AUDIO: Intervention Earth)
