Duncan Mills is a Belgian porn actor, and yet another wrestler in some Gachimuchi sources.
Japanese fans gave him the nickname "Kamata Gosaku" (鎌田吾作) after some misheard dialogue. It also led to another nickname from his "given name", "539", from "go" (5), "sa[n]" (3) and "ku" (9).
He appeared in several films, such as "Workout" (where he wrestled with Billy and was defeated), "House of Detention" (where he was tortured in Van's dungeon), and another video where he got himself a pet for Christmas.
Role in Gachimuchi Edit
Due to his line "How do you like that?" being misheard in Japanese as "kani ni naritai" (蟹になりたい, "I want to be a crab"), fans depicted him as either aspiring to be a crab, or being a crab himself.
