Paranoid Cowboy uses the skin dwmylc1, which is a blue and black plaid button-down shirt with a white T-shirt under it, dark blue jeans, a black cowboy hat, brown cowboy boots, and black sunglasses. He also sometimes talks to Mr. Trenchcoat, making a few strange remarks both in conversation and if a player interacts with him. He appears to exhibit the same paranoid behavior as Mr. Trenchcoat.
Serial Killer Theory
There is a theory stating that Mr. Trenchcoat and the Paranoid Cowboy are allies, working together to murder people. This theory however is not real, as Mr. Trenchcoat and Paranoid Cowboy are both normal pedestrians, and will attack the player only if the cheat is activated.
As the name implies, the Cowboy is extremely paranoid, and has a high chance of attacking the player if they annoy him. The pedestrian is also known to get into fights.
