Baris (The Doctor Trap)

Baris was the Doctor's number one fan. He spent most of his life searching for his "hero". Before he met the Doctor he had mega plastic surgery to make him look just like him, from voice to even having a second heart fitted. During the events on Planet 1 he helped the Tenth Doctor escape and save Donna Noble. During this he was chased around the planet by the hunters thinking him to be the Doctor. (NSA: The Doctor Trap)
