to restore his original height. The League defeats Amazo and then new team member Zatanna restores the Key to his former state. After the Justice League of America disbands and reforms as a small team of mostly new heroes based in Detroit, Ivo reactivates Amazo to attack this less experienced, "weaker" League. The android defeats all the new members but is finally stopped by Justice League founding members the Martian Manhunter and Aquaman. A different Amazo model is later activated and battles the superhero team the Conglomerate. This updated Amazo searches for Ivo and encounters the hero Aztek, who succeeds in reasoning with the android rather than overpowering it. This Amazo model also briefly battles the Resurrection Man before finally being destroyed. Before his destruction, the second model of Amazo is summoned into the future by the android hero Hourman, who wishes to meet his "ancestor". This Amazo copies Hourman's time-warping "Worlogog" artifact, becoming "Timazo" in the process. Timazo wreaks havoc with his new ability to manipulate time, but is defeated by Hourman and returned to his place in the past so his history can run its course. Another, similar model of Amazo later has several more encounters with Hourman. Another model of Amazo is activated that can wield multiple powers at once and is programmed to automatically upgrade its abilities to match those of all active Justice League members. Initially not understanding this upgrade, the Justice League calls in reserve members to help defeat Amazo, which only results in its power increasing. On the Atom's advice, Superman (active team chairman at the time) announces the League is officially disbanded. Programmed only to mimic the powers of active members, this Amazo is suddenly depowered and easily deactivated. Years later, Batman and Nightwing discover a partially built Amazo android in a weapons shipment and destroy it. Another Amazo participates in a massive attack by a group of villains on the city of Metropolis, but is destroyed by Black Adam. It is eventually revealed that after perfecting Amazo's absorption cells, Ivo combined this technology with human ova and DNA to create a "son" of Amazo who grows up as Frank Halloran, unaware of his heritage. Years later, Frank is a philosophy student dating a young woman named Sara when his powers are awakened prematurely. Rather than emulate his villainous "father", Frank hopes to be a hero called "Kid Amazo". Slowly becoming mentally
