Mr. Nasty is a character that materializes from Benton Tarantella's show Angry Nasty People. He is the embodiment of Eustace Bagge's cruelty and mean-spirited nature. He starred in Tarantella's show until he turned to his new star, Courage. Mr. Nasty went on to create his own talk-show with Eustace, whom he swindled out of 95% of the profits.
Appearance[]
Mr. Nasty looks identical to Eustace except that he wears black-lens glasses and emits a dark blue glow, giving the semblance of what Eustace would look like if he was possessed by another demon (different from the Mattress Demon). His attire somewhat resembles what his clothes looked like when Muriel didn't wash them for a year (see McPhearson Phantom).
Despite his cruelty and heartlessness, Mr. Nasty does have redeeming features and isn't an irredeemable villain. He is very sensitive to being betrayed by Benton, has some politeness, and a few comedic moments i.e. acting like a monkey and pointing out the truth that Eustace can't grow hair or plants, and even calling Eustace "Stupid Farmer", similar to Ma Bagge calling him "Stupid Boy".

Trivia[]
- His name could be a reference to an incident that occurred in London in 1994 where a man named Tom Halloran, known as Mr. Nasty, was caught selling banned horror videos such as Faces of Death to children. The tabloid newspaper News of the World reported the story with the headline "Mr. Nasty Sells Death Videos to our Kids". The title of the episode he appears in could also be a reference to this, as both events have something to do with videos and filming.
