He was the sinister leader of the Black Arms and the creator of his kind. For thousands of years, Doom planned to impose terror on the earth and use the local human population as a livestock for his minions. Black Doom is presented as a highly ruthless, sadistic, manipulative, and power-hungry tyrant. He regards humans as pathetic creatures that will lead themselves to their own extinction, and always looks down on them and their technology. He has neither affection nor sympathy for anybody.
