Identity theft
From Tardis Wiki, the free Doctor Who reference
Identity theft was the criminal act of assuming someone else's identity. On Gharusa Prime in 3764, the Ninth Doctor was arrested by Gharusan police on the grounds that he had taken the identity of the Doctor, protagonist of the holovid series Doctor Who?. In reality, "the Doctor" was actually Slist Fayflut Marteveerthon Slitheen, who wore a synthetic skin suit based on the image of the Ninth Doctor. (COMIC: Doctormania)
