Scary Jimmy is a bull who works as a janitor at T.U.F.F. As his name suggests, he is a very suspicious and strange person. He is implied to be somewhat of a shut-in, mentally unstable, paranoid, and potentially harmful. He even claims that he can memorize the backs of people's heads looking behind them or not.
Despite his large and gruff appearance, he actually has a light voice and sounds very nervous. He seems to be concerned about the voices he hears in his head, and it is implied that he has a habit of breaking things whenever he gets angry, such as his mop. He also appears to prefer working in the dark, as well as using only a few lights for when he is in his house.
- He is one of the few newly introduced T.U.F.F. agents to appear more than once.
- He is also one the few "minor" characters to appear twice in a row after his introduction, as he appeared in both Mud with Power and Legal Beagle, which were part of the same full episode.
- He is shown to have a knife and pike on his table at home for some strange reason, as well as having a picture of a skull on his wall.
- He actually has some small differences in his design in Legal Beagle: he has no hair on his face, his horns are much thinner in width, and his eyebrows are now straight and have a shine compared to his previous hairy eyebrows. This is odd considering that this is his second appearance within the same full episode pair.
