Varx

In an alternate timeline, Varx was a looter in Kiria City on Urbinia when the Daleks invaded the planet with the Time Destructor. Varx and his partner-in-crime Piril used the evacuation as an opportunity to loot the abandoned streets, where they encountered Jamie McCrimmon and Katarina. After Varx threatened both of them, Jamie knocked Piril unconscious to protect Katarina and sent Varx fleeing.

At the end of the invasion, the Second Doctor averted the change in the timeline by ensuring his previous incarnation arrived on Kembel to prevent the Time Destructor's completion. (AUDIO: Daughter of the Gods)

Behind the scenes
Ian Crowe gave Varx a voice inspired by from filmed adaptations of Oliver Twist. Max Keeble, who voiced Piril, played off Crowe to portray the characters as a kind of double act. (BFX: Daughter of the Gods)
