Varga

Varga is an Ice Warrior who pilots Iraxxa's ship in Season 15.

Role
Varga makes his first appearance in the fourth episode of Season 15, where he follows the Doctors (without the Sixth Doctor) around the deserted building on the planet Kyllon. Once the Doctors see him, he explains that he is not there to kill them, but is there to gather some intel for Iraxxa. He then leaves the Doctors alone.

Varga later returns in the next episode of the season where, after picking up the Eleventh Doctor who was shot into space in a small canister containing a USB stick, he pilots Iraxxa's ship over to the cave where the Sixth Doctor is still moping about his constant outbursts.

Varga then helps Iraxxa and Captain Azaxyr in rescuing the other Doctors from the Daleks and stopping their plan to infect every life form in the universe with Dalek nanogenes.
