If you don't know him he's GB Mario but not the one you're thinking he's from the "Mario's madness deluxe" his song is "golden land retake" (just listen it's fire) his origin (i'ma make it quick) was he was a normal entity in a bootleg copy of Mario land 2:six golden coins his creator "Christine hermer" was abusive to GB putting him in painful "coding" experiments so GB had ENOUGH and killed Christine when GB turned black and white (but in this chat he's just green and greenish) and GB would kill anyone who finds him
