Patrick has a very clueless expression on his face, with stubble covering his chin and red, mopey hair covering his head. He typically wears an equally red shirt with loose overalls and a black belt. He also wears a white pith helmet (now dark gray) and gray pants, though he now wears blue pants instead, especially in the Tales of the Adventurers comics and the fan video Thank You Mustache Maniacs.
In his cold weather outfit, his red shirt is swapped out for a dark gray suit with white undershirt. He also wears a red bow tie and a superfluous medal in this outfit.
Patrick is Lord Sinister's dumbest henchman who somehow finds his way out of situations in order to unwillingly torment his boss with his stupid comments another day. According to some dialogue at the beginning of Johnny Thunder and the Secret of Marco Polo, Patrick was part of a team led by Nevada Smith that was looking for the tomb of King Ramalamadingdong. When they were locked inside, they resorted to cannibalism, with Lord Sinister rescuing them a few days later. Indebted to him, they joined his team. In A Very Patrick Christmas, we learn that Patrick's parents are named Patricia and Porkins.
- Patrick is named after the character Patrick Star from the animated TV show Spongebob Squarepants. The characteristics of Patrick were influenced by that character as well.
- According to official Mustache Maniacs Film Co. canon, Patrick and his family have the last name of Hooligans.
- His red shirt allows him to stand out from the other pith helmet-wearing characters from the Johnny Thunder films.
- Originally created to be a one-time character for Johnny Thunder and the Secret of Marco Polo, Patrick has become Lord Sinister's longest-lasting henchman.
- Patrick now appears on a line of fashion and personal products called "Patrick, Shut Up! Collection." The collection is currently available through Mustache Max's Merchandise Market.
