Major Story Arcs
Driven mad by Lex Luthor's constant theft of his ideas, Hamilton is briefly held in a mental institution where he recovers from the stress. Upon his release he takes up residence in the Suicide Slums and becomes involved with Superman as the superhero's scientific adviser. During this time he provides numerous technological supports to aid in his adventures, including the Phantom Zone Projector, powered suits, and robots.
Death of Superman
When Superman comes under attack by Doomsday, Hamilton attempts to aid the hero. He creates a laser cannon which he and Bibbo Bibbowski use against the creature. The cannon hurts Doomsday, but it is destroyed shortly after its inaugural use, when Doomsday falls onto it. After the two combatants have exhausted each other and Superman lies apparently dead, Hamilton attempts to revive the hero with a CPR device. His efforts fail and Superman is declared dead. Hamilton is overcome with guilt because of his inability to save his friend.
The Fall of Metropolis
During the chaos of the Fall of Metropolis, Hamilton is tasked by Superman to attempt to reverse engineer one of the helmets belonging to Team Luthor soldiers. After the release of the hallucinogenic gas over Metropolis he is attacked by one of the affected citizens and shot in the arm. Despite his injury he is able to enact his plan to disperse the hallucinogen by dumping enzymes in the bay. Assisted by Superman, he manages to disperse the cloud. Despite Superman's best efforts to get him adequate medical care, the wound to his arm is too serious, and it is amputated. He later creates a cybernetic arm with which to replace his lost limb.
Upon the arrival of John Henry Irons to Metropolis, Hamilton begins to feel that he is superfluous to Superman, who now has Irons to rely on for technological support. During the B13 Event he vanishes from the city, resurfacing some time later as Overmind, leading a cult that is planning to resurrect Brainiac. Following the defeat of the gang he claims that the Brainiac technology in his cybernetic arm was responsible for his actions. As this is apparently the case, he soon returns to his position as friend and assistant to Superman.
Becoming convinced that Superman's presence on Earth was slowly draining the Sun of energy and would eventually lead to the destruction of the Earth, Hamilton takes on the persona of Ruin and begins attacking Superman's loved ones. He also dedicates a great deal of time to framing Pete Ross, one of Superman's close friends and the current President of the United States. He ultimately reveals his true identity to Superman and attacks the hero, apparently killing Mr. Mxyzptlk in the process. The pair fight, and Superman is ultimately able to defeat his erstwhile friend and rescue his hostages Ross, Lana Lang, and their child. Defeated, Hamilton is then imprisoned
Hamilton, still going by Ruin, joins Alex Luthor's Society of Super-Villains and aids them in carrying out Luthor's plans.
