Farmworld Martin, referred to as Finn's dad, is an alternate version of Finn's biological father, Martin, who appears in the season 5 premiere "Finn the Human" and "Jake the Dog." He is one of the only known characters who lives in Farmworld.
Farmworld Martin appears to be a normal human being with peach-colored skin. He wears torn up blue jumpers, an old long-sleeved red shirt, and an old pair of black boots. He has a bald head with one curly hair on the top and a shaggy light brown beard which covers his mouth and loops behind his ears, similar to Martin. He also appears to be a bit muscular and is much thinner than Martin.
- He was involved with the Destiny Gang somehow, which is why Finn is trying to sell Bartram to pay them.
