Conrad Finch

From Tardis Wiki, the free Doctor Who reference

Conrad Finch was a convict who was sent to a colony planet (later named Basingstoke) where he worked with Nerena Cargill). He wanted to kill the creature that Buchan Foster had become and decided to accompany the Eleventh Doctor to figure out the answer to the mystery. He pulled a gun on the Time Lord, but the Doctor blasted it apart with his sonic screwdriver and sent Finch unconscious. (COMIC: Supernature)
