Hargreaves (Aquitaine)
- You may be looking for a human butler of the same name.
Hargreaves was the robot which ran the HMS Aquitaine.
He had multiple humanoid bodies which each had different functions. His butler body was described as tall and wore a bowler hat, and his medic body had a screen on its chest. (AUDIO: Aquitaine)
The Doctor disconnected Hargreaves' head from his butler body and used it by patching it directly into the TARDIS to help save the crew-members of the HMS Aquitaine. This event is similar to how he would do the same thing with Handles. (TV: The Time of the Doctor [+]Loading...["The Time of the Doctor (TV story)"])
