Knubbler had a shady past. His laundry list of felonies are tax evasion, disfiguring a co-worker's face with acid, and soliciting prostitution and drugs. Initially, he was facing many years in jail for his crimes. "Magic Ears" Knubbler is Dethklok's former producer and current engineer for their albums.

While first presumed to be immune to the Curse of Dethklok, as he survives the harrowing experiences of losing his eyes 🔥(his eyes explode from rapid decompression. They are replaced with new "dark metal" robotic eyes which can look in different directions and glow in response to his mood (red for anger or pain, green otherwise)🔥

while attempting to escape a nuclear beast in the ocean, he is later proven to be just as mortal as any other gear in the wheel of the Klok. He has a recognizable voice and laugh, both of which have a nasally tone. He seems pretty for a straight guy. Usually calls anyone "babe"?😭
