The Mastah

The Mastah is one of the antagonists of Doctah Who. He is a Time Lord, like the Doctah, and has the ability to regenerate. Interestingly, the Mastah appears to only regenerate in between his normal self and Ajit Pai, unlike other Time Lords who regenerate into different people each time. Not much is known about his background, but most of the plot line takes place in The Mastah's House. He appears to be the only character that is aware that Doctah Who is a webseries, although how he learned this is not known. He used to be called the Master in Doctor Who, but has since changed form and name; why he regenerated before settling down in The Mastah's House is unknown.

Description
The Mastah does not have any special clothing that stays consistent throughout the show, except perhaps his glasses and his hat. The Mastah also seems to be very good at playing the vibraphone, as demonstrated in Season 2 Episode 2, and capable of holding up to ten mallets at a time and playing sounds that even a vibraphone cannot normally make. He is also friends with many of the Ohtarians, as he used to play Magic: The Gathering with them and the Buildah. The Mastah is also apparently a Trump supporter and also supports repealing net neutrality, which could be a consequence of regenerating into Ajit Pai. The Doctah's political affiliation is unknown, although he has shown resentment towards Ajit Pai.

Story
In the first episode of Doctah Who, the Mastah is defeated by the Doctah in a very action packed battle at his front door. He then regenerates into Ajit Pai. He then was next seen in Episode 4: The Doctah Falls, but this was not actually him; instead, it was an Ohtarian who had assumed the form of the Mastah.
