Bennett (The Rescue)

Bennett was a 25th century murderer who passed himself as the alien "Koquillion" in order to escape justice.

Profile
While a passenger on a ship en route to Astra, Bennett murdered a fellow passenger and was caught. When the ship crashed on Dido, Bennett killed the rest of the passengers and the Didonians to cover up his earlier murder.

[Vicki Pallister]], who hadn't attended the meeting between the humans and Didonians, was unaware that Bennett had killed anybody, and he planned to use her innocence to protect himself from the authorities. He told her that the Didonians had wiped out the others, and pretended that he had been paralysed below in the attack. He also claimed that he was protecting them from a native named Koquillion who was actually Bennett in a Didonian ceremonial mask. Bennett's crimes were exposed by the Doctor, whom he attempted to kill. Before he could do so, he was confronted by two surviving Didonians, and while backing away from them, fell from a rock ledge to his death. (DW: The Rescue)
