Origin

As a child, Anthony Ivo developed a crippling fear of death. This fear remained with him into adulthood, and drove him on his obsessive quest for immortality. As an adult, he became involved in the study of cybernetics, and found work with Locus, a criminal organization. Locus enabled him to further his research when he dissected an Appelaxian. Using the knowledge obtained from his research, he was able to create the android Amazo.

Creation

Anthony Ivo was created by Gardner Fox and Mike Sekowsky.

Major Story Arcs

Amazo

Using his android creation, Ivo attacks the Justice League, hoping to utilize their powers to create an immortality serum. He fails, and is defeated by the League.

Immortality

Several years after his encounter with the Justice League, Ivo discovers an immortality serum, and drinks it. The serum worked, but has the side effect of disfiguring him, and causing his skin to become hardened and scaly. He blames the Justice League for his disfigurement, and retreats into insanity, frequently lashing out at the League. He creates a number of duplicates of himself to alleviate his loneliness, but his own creations turn on him, locking him away and carrying out their own revenge missions on the League. Ivo reappears a year later, with a private island filled with robots he has created, including the Amazoids, which as similar to Amazo but are capable of absorbing only one power each. These Amazoids succeed in stealing a number of powers, and return to Ivo, who intends to use them to commit suicide. He has realized that the scaly skin was not a side effect of immortality, but the immortality itself; he is slowly becoming a living statue, completely immobile but still capable of feeling the immense pain of his condition. His Amazoids fail in their task of killing him, but he is cured by Ice, who, taking pity on him, unintentionally uses a Green Lantern ring to cure him. Despite his experience with the painful results of immortality, he later willingly takes the serum, fully aware of the ultimate consequences.

Legends

While Amazo has continued to be a recurring threat to the Justice League, Professor Ivo has created other androids that have plagued the League besides Amazo. His androids were responsible for the deaths of the two members of the JLA, Vibe and Steel. Vibe was killed outright by one of the androids during the Legends crossover. In the same storyline Steel was critically wounded, comatose and put on life support.

Tomorrow Woman

Ivo forms a vitriolic working relationship with fellow mad scientist T.O. Morrow. Together, the two men create the android Tomorrow Woman, with Ivo working on her body and Morrow creating her brain. Within her body they conceal an EMP bomb wired to go off at a specific time and kill the whole Justice League. Though the two work well together, their personalities clash, and they bicker constantly, frequently exchanging insults. When Tomorrow Woman gains free will and refuses to kill the Justice League, Morrow secretly rejoices, as he feels this proves once and for all that he is the more intelligent man. Later, when they are imprisoned together, Morrow reports Ivo's escape plans after growing weary of Ivo's boasting. Despite this, they maintain a friendship of sorts, and Ivo appears to hold no grudge.

Ivo is also involved in the creation of Genocide, as he is the one sent to Auschwitz to collect soil for her.

Following the Final Crisis, he is a member of the third Cheetah's Society.
