Emaciated Master

The Emaciated Master (Also known as Peter Pratt) is the first incarnation of the Master to appear in "The Doctor Who Figurine Adventures", first appearing in the sixth episode of Season 6.

Role
The Emaciated Master is first seen when Lady Cassandra tells him about the Doctors releasing the Teller from his life as a prisoner and how crafty the Doctors are. The Master replies by saying that it is to be expected before saying that he wishes to see the Doctors die in shame and dishonor. He spends the rest of the season hunting down the Doctors and their friends and trying to kill them. But each time they encounter him, they outsmart him, even when he opens a pit to unleash the Beast.

In Season 7, the Master locates the First Doctor, who thinks that he's someone in a Halloween costume. The Master tries to kill the First Doctor, but he thinks that his attempts to kill him are trying to help him. In the Season 7 finale, Rassilon shows up to help him. The Master then shoots and kills D84 and Chantho and takes the First Doctor hostage.

In Season 8, the Doctors manage to save the First Doctor from the Master's clutches. Unfortunately, the Master manages to separate the Eleventh Doctor's consciousness from his body, leaving the Eleventh Doctor as a blue hologram.

The Emaciated Master does not appear again until the end of Season 10, where he convinces Harold Saxon to join his own army. Throughout the rest of the series, he accompanies Harold Saxon in recruiting the rest of the Masters into their army so they can destroy the Doctors and conquer the universe.

Personality
This incarnation of the Master feels a very strong hatred for the Doctors and their allies, but is still willing to have a civil conversation with any of the Doctors when it suits him.

While he states that nothing he does is pointless, he seems more comfortable with killing people for the sake of it, even showing a sadistic pleasure when killing.

The Emaciated Master has stronger telepathic powers and willpower, proclaiming that "only [his] hate [keeps him] alive."

Meticulous in his schemes, the Emaciated Master plans for every obstacle imaginable and putting in place a counter for it.
