Charonid
From Tardis Wiki, the free Doctor Who reference
The Charonids were a race of large brown, mutant-like creatures with giant pincer claws for hands and two-toed feet. They were capable of body-swapping over a distance, causing a change of eye-colour to red and changes in personality. The Doctor and Amy Pond encountered a Charonid on board a prison ship. It had escaped and stunned the crew, taking Cormac's and later Amy's body as a host. It was eventually trapped in its own body by the Doctor, who held it in a force field. (COMIC: About Face)
