The Evil Renegade

"The Evil Renegade" was allegedly the chosen alias of the renegade of the Great Houses with whom Chris Cwej travelled. However, this was actually the Seventh Doctor: the "Evil Renegade" framing was part of the brainwashing the Great Houses used on former companions of the Renegade during the War in Heaven, so as to ensure their undivided loyalty to the orthodox Great Houses. (PROSE: Dead Romance, Judy's War) Another name used for the same purpose was the Defector. (PROSE: The V Cwejes)

While working for the Great Houses, Chris Cwej came to believe that he had once been kidnapped by an insane renegade Time Lord who called himself "the Evil Renegade". This renegade carried out experiments on Chris and other captives in the laboratories of his timeship, and killed Chris' friend by sending her into the middle of a war. (PROSE: Dead Romance) In reality, Chris' travels with the Doctor had been voluntary, (PROSE: Original Sin) and Roz Forrester had joined that war against the Doctor's advice. (PROSE: So Vile a Sin) After hearing Chris' story, Christine Summerfield doubted that anyone would call themselves "the Evil Renegade", and suspected that these memories had been implanted by Chris' superiors to help control him.

Likewise, Helen Greyridge had memories of "a strange little man with an umbrella, some sort of evil renegade." Many of the Evil Renegade's former traveling companions proved to be adequate agents for the Houses in the War. (PROSE: Judy's War)
