Arthur Stengos
Arthur Stengos was one of the finest angrometists in the galaxy. He passed away, however, and had himself placed into suspended animation at Tranquil Repose on Necros. It was not like him at all to place himself in suspended animation in the vein hope that someone would come up with a cure for the organic breakdown of his body.
The Doctor and Peri arrived on Necros for the funeral, but Stengos' daughter, Natasha Stengos, with the help of a doctor friend, Grigory, broke into Tranquil Repose after she couldn't get her father's body from the Courts. She was part of a group that were trying to find out if the Resting Ones were being taken out of suspended animation, and when they opened Stengos' casket, a manniquen was inside.
She later found him: Arthur Stengos' head was placed into a Glass Dalek and he was slowly being changed into a Dalek, going in and out of a Dalek-mindset as he spoke to her. She killed her father at his request and the Doctor never saw the state he was in. (DW: Revelation of the Daleks)
