Obsessed with defeating the Justice League Professor Ivo created an android with special absorption cells that could take on the powers of any super-powered being it came into contact with, dubbing the construct Amazo.
Ultimately the android has no interest in battling the Justice League, but when reactivated after numerous defeats it attempts to fulfill the original programming to destroy the heroes so that it may ultimately be at peace.
