Crimesmith

Golden Age Origin
Crimesmith was a murderous criminal genius who made extremely advanced weapons for organized crime syndicates. He was eventually caught and served time in jail, but he continued to keep up on advances in science and technology. When he was released, he developed the Hand of Horror to kill those who had sent him to prison, including the arresting officer, Harney, Judge Wight and science expert Mr. Roberts. However, Doll Man, a friend of Roberts, stopped the Hand and followed it back to Crimesmith's lair.

Crimesmith was a technological genius, capable of creating advanced robotics. He claimed to have been more of a physical threat in his earlier career.
