Mal is a blue-collar industrial farm employee. He has faced discrimination all his life for originally being livestock before he was super-domesticated and turned into an animalian citizen. He was pressured into taking a job like this. Being forced to slaughter his own kin for the empire just to prove he's better than livestock, has taken a brutal toll on his mental health.    

His voice claim is: "General Chungus" from "The Minecraft Movie"
