"Sad Tony"

From Tardis Wiki, the free Doctor Who reference

"Sad Tony" was an alien who appeared on a missing poster displayed in what appeared to be a backalley in Cardiff, but was actually an image generated onboard the Abzorbaloff's ship in 2009. Sad Tony was infact onboard the ship whilst the Tenth Doctor confronted the Abzorbaloff and the Krakanord. (WC: The Genuine Article)
