David Karpagnon
From Tardis Wiki, the free Doctor Who reference
David Karpagnon was a resident at a children's home after his parents had abandoned him. He had a dissociative personality disorder which caused him to think he was a DeathBorg 400 on a secret Earth based mission.
Thinking himself as Karpagnon the DeathBorg 400, he plotted to escape the house and destroy it including all of the occupants, with a specific hatred for a Doctor Petrie. However the voice of The Doctor (fictional character)|the Doctor]] helped keep him right. This voice was also from within his brain, and when he realised his reality, he went back inside the house and went to bed. (PROSE: The Terror of the Umpty Ums)
