Android created by Professor Ivo to assist him in collecting the oldest living animals on Earth in an attempt to distill from their essences an elixir that would grant Ivo immortality.
Amazo has the ability to mimic the superpowers and other abilities of anyone within a certain range.
In his quest to collect the oldest living animals, Amazo acquires the powers and abilities of Aquaman, The Flash, Green Lantern, the Martian Manhunter and Wonder Woman of the Justice League of America. He also somehow produces exact duplicates of Green Lantern's power ring and Wonder Woman's magic lasso. The League subsequently regain their powers and defeat Ivo and Amazo (The Brave and the Bold No. 30, Jun/Jul 1960: "The Case of the Stolen Super Powers").
Amazo returns to battle the JLA many times over the years, as well as facing Superman in solo combat.
