Bostock

"He may smell like rotting flesh but he's an excellent squire."

- Orcini

Bostock was the squire to Orcini of the Grand Order of Oberon. Bostock had unfallable instincts and the only time Orcini didn't listen to him resulted in Orcini receiving an artificial leg.

Bostock's philosophy was to do as little about his personal hygiene as possible. Though Orcini believed that things should be honorable, Bostock believed that things should just be done, as when Orcini insisted on using his weapon which jammed during its last use and Bostock insisted on using a pistol.

Bostock and Orcini were hired by Kara to assassinate The Great Healer (Davros). They both broke into Tranquil Repose on Necros and tried to kill Davros. When they destroyed a "fake Davros", the real Davros revealed himself to them and they came under attack from his Imperial Daleks. They were both wounded.

Bostock tried one final time to kill Davros, but shot his hand only. Davros screamed in pain as a Dalek exterminated Bostock. Orcini, using the bomb given to him by Kara, who had told him it was a transmitter, triggered an explosion while holding Bostock's body, destroying the catacombs of TR and the Daleks in hibernation.
