Zephon (The Daleks' Master Plan)

Zephon was the Master of the Fifth Galaxy, having gained the title after overthrowing the Embodiment of Gris in 3932. (BFA: Neverland) He represented his home galaxy when he allied himself with the Daleks in their plan to conquer the Solar System, and persuaded Beaus and Celation to join as well. Bret Vyon knocked him unconscious and The Doctor impersonated him, stealing the Time Destructor's taranium core while doing so. Zephon was later exterminated by the Daleks for his failure.
