Amazo is a recurring DC Comics antagonist who first appeared in The Brave and the Bold #30 (June 1960). The Amazo robot was created by Professor Ivo as a means for immortality and to showcase his intellect. Amazo was sent by Ivo to destroy the Justice League and beats the entire League on its first encounter with its combined abilities. Amazo nearly succeeds in destroying them, but was defeated by Batman when he exploits the android's newly acquired weakness to Kryptonite. Amazo remains a constant threat to the superheroes ever since. Amazo's synthetic body was built with "absorption cells", which duplicate the powers and abilities of metahumans in his proximity, such as Superman's strength and flight, Flash's speed, Martian Manhunter's telepathy and intangibility. Later on, it could create objects the heroes use such as the Green Lantern's power ring and Wonder Woman's lasso.
