C'rizz

C'rizz was a male Eutermesan from Bortresoye.

Biography
C'rizz first encounted the Eighth Doctor and Charley Pollard when they entered the Eutermes zone on Bortresoye. The Doctor had been exiled to Bortresoye's universe from his own, and deprived of his TARDIS. Furthermore, a sinister entity known as the Kro'ka has been sending the Doctor and Charley across the various zones that Bortresoye was divided into for reasons that, at that time, were unexplained.

When C'rizz met the Doctor and Charley, he was grieving the loss of his mate, L'da, whom he had left behind when he had escaped the Kromon biodome. With the Doctor and Charley, he returned to rescue L'da and free his people from the Kromon. He succeeded in the latter, but was forced to kill L'da, who had been transformed into a Kromon queen. Still coming to terms with what he had done, he asked to join the Doctor and Charley when they went to the next zone in search of the Doctor's TARDIS and the answer to the mysteries of the universe they were in.

Eventually, it was revealed that C'rizz was an adept of the Church of the Foundation, which believed that all things must die, and had murdered in its name before he had met L'da and left the Church. It was also revealed that the Eutermesans were more than physical chameleons, but emotional and mental ones as well, shaping their personalities to those around them but also making them easily manipulated.

When the Doctor and Charley returned to their own universe, C'rizz came with them, as he trusted the Doctor to keep him stable and himself. They emerged on an Earth conquered by the Daleks, who unsuccessfully tried to brainwash C'rizz into becoming their new Emperor. The Dalek attempt added to C'rizz's deteriorating mental state; he would continue to hear, in his mind, the voices of the people he killed. (BFA: Terror Firma)

C'rizz once attacked bystanders in King's Cross Station. The Doctor and Luke Tillyard managed to render him unconscious and took him back to the TARDIS. (ST: Salva Mea)

C'rizz was later granted massive psychic powers on a planet that resembled Hell, with citizens who had been turned to demons save one domed city, eventually transforming into a physical form that Charley likened to Lucifer. The Doctor theorised that the Eutermesans had genetically engineered C'rizz to house their souls in some mad bid for immortality. C'rizz eventually gave up his new form and powers by restoring the planet and its citizens to their original forms. This exhausted C'rizz, who thanked the Doctor for healing his emotional wounds (save for L'da's death) and called Charley his sister before dying, his body turning to ashes. (BFA: Absolution)

The impact of C'rizz's death was felt by the Doctor and Charley for some time afterwards. (BFA: The Girl Who Never Was)
