Pavo 1 (The Black Hole)

Pavo was a constable of Chapter 9, the Time Lord police force. Pavo was pursuing and caught up with him at a research station. However, the Monk shot him with Pavo's own baton. The Monk then stole Pavo's perception-altering ring in order to impersonate him. The Monk thought that he had killed Pavo, but with the help of the Second Doctor and Jamie McCrimmon, he was able to regenerate into a new incarnation. (AUDIO: The Black Hole)

Appearance
This incarnation of Pavo was described as a bald man. (AUDIO: The Black Hole)

Behind the scenes
Although not explicitly stated in the story, Simon Guerrier intended for the two Pavos to be earlier incarnations of the Master. "Pavo", Latin for "peacock", was chosen to fit the Master's personality. Hints towards this identity in the story include the "curious silver baton" wielded by Pavo as a weapon, as well as the hypnotic abilities she displayed. The Master had earlier been suggested in the novella Time and Relative to have originally been an agent of Time Lord law enforcement tasked with tracking down Renegades, much as Pavo does in The Black Hole.
