Finney

Finney was a burglar who attempted to steal the Doctor's TARDIS and use it to break into banks. He posed as a fellow scientist to case the Doctor's house, then later entered the cellar, but was confronted by the Time Lord. When Finney tried to distract him with a smoke bomb, he accidentally started a fire, forcing the Doctor to take him with him into the TARDIS. Upon dematerialising, the ship was transported to Skaro by the Daleks, who planned to turn the Doctor into a humanoid Dalek. After they escaped from the Dalek city, Finney aided the Doctor in using of a herd of dinosaur-like creatures to destroy the Daleks, and was then returned to Earth in the TARDIS.
