The Death's Head Guard appear to be similar in design to the Death's Head Unit created in the future of Earth-6216. However, how these units ended up in the Earth-616 reality is a mystery. Some 300 of these unit ended up passing through the Great Portal over the planet Sakaar some years ago and were used by Red King Angmo-Asan to win the so-called Spike War. He later used them to be his elite guard following the war.[​2] The Death's Head Guard were mostly used to keep slaves in line and stop insurrections on the planet.
