Silver Age Origin

Demo was one of the Warlord's most formidable agents. He had an underground lair, an assistant named Satanna, and an army of humanoids called sub-men. In his first appearance, he sent his sub-men to steal some chemicals but, they were stopped by NoMan. Later, he stole Dynamo's belt, NoMan's cape, and Menthor's helmet; briefly gaining the entire team's powers.
