|Prof. Emil Hamilton|
|Appeared in|| Superman: Legacy|
Justice League Unlimited: CADMUS Crisis
|Actor|| Victor Brandt|
Professor Emil Hamilton is a former friend of Superman's who felt betrayed when Superman went rogue, so joined Cadmus.
Hamilton retrofitted Superman's Kryptonian ship to be spaceworthy again.
As one of Superman's closest allies, Hamilton was perhaps the most affected when Superman turned rogue, after being brainwashed by Darkseid. Even more unsettling to the scientist was when Superman escaped custody and brought a severely injured Supergirl to Hamilton for medical treatment. When Hamilton confessed that he was reluctant to do for fear of being charged with treason, Superman, in a flash of angered desperation, threatened him into cooperating. Although Superman immediately apologized for his rash act, Hamilton was shaken by the revelation that, even when free of the brainwashing, Superman was still capable of such wrath.
When Superman confronted Hamilton inside a Cadmus facility, Hamilton refused to deny or defend his actions, insisting that the world needed protection from the likes of Superman. However, there were sometimes indicators that Hamilton felt remorse for what he had done, especially when he saw the ruthless and deceptive methods of his superiors. During the above confrontation, as soon as Superman left, Hamilton sagged, as though exhausted. Likewise, just before Galatea left Cadmus to lead an attack on the Watchtower, she hugged Hamilton and said, "Goodbye, Daddy". As she left, his face clouded, as he realized how low he had sunk: creating a sentient being for the sole purpose of being a weapon.
During the attack, when Amanda Waller realized that Luthor had double-crossed Cadmus and stolen much of its cutting-edge technology, Hamilton made a quick examination of the technology and realized that it enabled Luthor both to frame the Justice League for attacking the earth, and to build himself an android body that would give him superpowers. Afterward, Luthor's plan was thwarted and Cadmus was disbanded. Hamilton's activities after that are not known.
