Cormac
From Tardis Wiki, the free Doctor Who reference
Cormac was a crew member aboard a prison ship that was transporting a Charonid. When the creature escaped it body-swapped with Cormac and knocked out the remaining crew with a stun-gun. The Eleventh Doctor and Amy Pond’s arrival resulted in Cormac being returned to his own body and the Charonid being restrained once again.
