Professor Ivo is a mad scientist and an enemy to the Justice League. His obsession with prolonging life lead to a career in cybernetics, and he achieved immortality through a special serum. This had the unfortunate side effect of giving him a monstrous appearance, because he used turtle DNA. The most famous robots he created include Amazo and Tomorrow Woman. He has also been a member of Locus and the Secret Society of Super-Villains. Professor Ivo was created by Gardner Fox and Mike Sekowsky, first appearing in The Brave and the Bold #30. (1960)
