The Evil Renegade

"The Evil Renegade" was allegedly the chosen title of a malicious renegade Time Lord with whom Chris Cwej, and many other companions, travelled at some point before entering the employ of the Great Houses in the lead-up of the War in Heaven. In actuality, it was with the Doctor that they had all travelled, but when recruiting some of the Doctor's former companions for their own purposes, the Houses brainwashed them to believe they had been experimented on by the Evil Renegade instead, to ensure their undivided loyalty.

History
The Great Houses were accustomed to indoctrinating members of the lesser species into willing service through "briefings" and other forms of brainwashing, (PROSE: The Book of the War) and many of the Evil Renegade's former traveling companions proved to be particularly adequate agents. (PROSE: Judy's War)

While working for the Houses, Chris Cwej believed he had been kidnapped by an insane renegade Time Lord, a mad scientist and criminal mastermind who called himself "the Evil Renegade" and carried out experiments on Chris and other captives in the laboritories of his timeship. He also sent Chris's friend to be killed in the middle of a war. (PROSE: Dead Romance) In reality, Chris' travels with the Doctor had been voluntary, (PROSE: Original Sin, et al.) and Roz Forrester joined the war against the Doctor's advice. (PROSE: So Vile a Sin) Cwej knew that, before or after he travelled with Chris Cwej, the Evil Renegade had travelled with his companions into sphinx-space, where he waged a "one-man war" against the Kings of Space. According to Cwej's edited memories, after multiple spaceship battles and the destruction of the Gods' worshippers' cities, the Evil Renegade escaped, leaving his human slaves behind; however, he kept the Gods' bottle universe, which was ultimately confiscated by the Great Houses when they "caught up with him". (PROSE: Dead Romance)

According to Cwej's memories, "the Evil Renegade" was the title the renegade had chosen for himself. After hearing Chris' story, Christine Summerfield doubted that anyone would call themselves "the Evil Renegade"; she correctly suspected that these memories had been implanted by Chris' superiors to help control him. (PROSE: Dead Romance) Another name used for the same purpose was "the Defector". (PROSE: The V Cwejes)

Helen Greyridge also had memories of "a strange little man with an umbrella, some sort of evil renegade." (PROSE: Judy's War)
