Doctor Who: 10 Most Unlikely Allies Of The Daleks
4. Mavic Chen
Featured in 1965-66's epic twelve-part story The Daleks' Master Plan, Mavic Chen was the Guardian of the Solar System and a traitor to humanity.
Siding with the Daleks and swaying the delegates of the Galactic Council to join with them, Chen and his allies from Skaro planned to use the deadly 'time destructor' to help conquer the Solar System. Using Chen's authority, the Daleks were granted access to the solar system where they assembled an invasion force.
When the First Doctor and his companions intervened, Mavic Chen pursued them throughout history with the Daleks and time destructor in tow. This included a stand-off in Ancient Egypt and a battle in the Daleks' base on Kembel where the Varga Plants patrolled.
A vain and twisted despot, Chen slowly began to forget that he was working with the Daleks and instead believed that they were working for him. Going above his authority and forgetting how powerful the Daleks were, the Daleks soon realised that he had outlived his usefulness.
Mad with power and exhibiting a God complex, the Guardian of the Solar System proclaimed himself to be immortal - even as the Daleks gunned him down.
