Professor Anthony Ivo (pronunciation: Eiy-voh) is a fictional character, a mad scientist in DC Comics.

Professor Ivo first appeared in The Brave and the Bold #30 (June 1960) and was created by Gardner Fox and Mike Sekowsky.

Anthony Ivo grew up with a crippling fear of death. The thought of his life ending was so great that he even avoided his own mother's funeral. For Ivo, avoiding death became his life's obsession. Ivo took to studying cybernetics and soon became an employee of the criminal organization Locus, where he gained new insights through the dissection of one of the Appellaxians. He used this knowledge to build Amazo. Pre-Crisis on Infinite Earths, his desire to perfect Amazo was so great he had little qualms with killing his own father and a complete stranger in the benefit of the mental and biological templates he needed to create the android. In any case, both Pre- and Post-Crisis, he had Amazo attack the JLA in the hope of using their powers to imbue himself with immortality. Pre-Crisis he tried to use Amazo to steal long-lived creatures. He captured the JLA, save Batman and Superman, in gas filled cylinders, stole their powers and placed them in Amazo. The powers enabled him to make a potion that would allow him to live for 500 years, and when needed he can make more of the potion. He then told Amazo to remove their memories. However Green Lantern recharges his ring, having used the yellowish-greenish gas he had inhaled, then exhaled to protect him from the ring, and draws the powers out of Amazo and back to their rightful owners, also giving them back their memories. Ironically at the end of the story Ivo is sentenced to 500 years, while Amazo is stored in the trophy room.

Years later, Ivo discovered an immortality potion and drank it, but found that the immortality brought with it horrible disfigurement that made his skin scaly. He blamed this on the JLA and drifted further into insanity as he attacked the League on numerous occasions. Ivo built duplicates of himself to keep him company. These duplicates were repulsed by the insanity of their creator and locked him away, then carried out his dreams of revenge by attacking the new Justice Leaguers (Vibe, Gypsy, Steel and Vixen) and killing Vibe.
