Owl (Mortal Beloved)

Owl was the robot protector of an old mansion called Stormlight House, which floated in space. He lived there along with Violet and her master Wesley Sparks. He first encountered the Tenth Doctor and Majenta Pryce when they came to visit. The Doctor fixed his television and he joined the Doctor in looking at the Holograms. When a bug hit the system the Holograms turned on them. Owl's legs were later taken off by Violet and replaced by wheels. Owl (under the control of Wesley) fired at the Doctor but was then reprogrammed by him and freed from Wesley's control.(DWM: Mortal Beloved)

After the Doctor and Majenta had left, Intersol, enemies of Majenta, came to Stormlight House to look for them. In a archive clip Owl and Violet were seen with their hands in the air. (DWM: The Crimson Hand)
