Baris
Baris is 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 One he helped the Doctor ecape and save Donna. During this he was chased around the planet by the hunters thinking himself to be the Doctor. (NSA: The Doctor Trap)
