Mince is Chief of the Churrasco Tribe. He is revealed to Meat's long-lost father during the Gruesome Threesome Arc, specifically during Mantaro's fight with Bone Cold. It is at this point when he is murdered by Bone Cold, although this was changed in the 4Kids dub to a 'broken hip'. Mince reappears at a later date as a spirit/hallucination to other characters, while an image of him appears in the Ultimate Chojin Tag Tournament as the computerized image of his ancestor (who shares an uncanny resemblance).
He appears at the Superhuman Council Assembly Hall on Planet Kinniku, where he engages Mantaro in a discussion, alongside other important characters of the older generation.  He often witnesses the matches, such as the match with Fork the Giant, and he is respectful to Check Mate and offers him a seat beside him to watch the match. 
Mince also appears on the beach, between the match with Hanzo and Bone Cold, where he momentarily bonds with Meat and asks him about his life.  It is revealed Mince is on a most-wanted list, with Bone Cold out to assassinate him.  Mince is kidnapped by Bone Cold and held hostage in Shuri Castle in Okinawa, and placed in the jaws of a stone dragon, which Bone Cold elbow drops upon whenever Mince tries to hide his secret. It is during the Mantaro Kinniku vs. Bone Cold match that Mince reveals he knows Bone Cold's secret, implying that he will speak it should Bone Cold force Mince to reveal his secret, and - afraid of his upbringing being outed - Bone Cold threatens to kill him.  Bone Cold reveals that Mince is Meat's father, after having sold his son to the Kinniku family for money, and - as Mince tries to stop the revelation from going further - he is stabbed in the stomach by Bone Cold. 
Mince reveals to Meat that Bone Cold was partially telling the truth, but that he loved Meat very much, and that they only gave Meat away so that he could protect the universe.  Mince reiterates that he loves Meat and always watched over him, and he can pass happily knowing his son became such a great Chojin, before he dies in Meat's arms.  Mince's body is taken to a chapel of rest. 
- The Italian dub keeps Mince (called Master Minch) alive, but makes clear that - while he will survive - he will likely be crippled for life.
