|Occupation||Founder and Owner of McFist Industries|
|Spouses||Mother McFist (assumed)|
|Children|| Terry McFist|
|First Episode||McOne Armed and Dangerous|
- McFist talks about his dad in "Fart-Topia," mocking Terry because he isn't the strong businessman that their dad was. Terry retorts that he never wanted to end up like his father.
- In a flashback in "McOne Armed and Dangerous," Hannibal, as a little boy, watches his father make McSquiddles, the product that began McFist Industries, in a factory.
- Like his son Hannibal, Father McFist has a robotic arm, and whether or not it came from the conveyor belt which he warns his son about is not confirmed.
- Father McFist is the first parent of the main cast shown in person in flashback.
- His hat and suit were possibly inspired by the Mad Hatter's from Alice in Wonderland, though it is more likely that he simply mocks the idea of a stereotypical nineteenth century "robber baron" (with a steampunk twist in regard to his arm).
