Magma

Mike Morgan was once a prize-winning physicist until he became the molten powerhouse known as Magma, the leader of the Terrific Trio.

History
Mike Morgan had a prospering life. He had a successful career, and was engaged with his beloved Mary Michaels. However, Morgan also had a treacherous friend ― Dr. Hodges. Hodges, who had long coveted Morgan's fiancée, plotted to take Morgan out of the picture. Morgan was double-crossed and consequently transformed, along with Mary and Stewart Lowe, into a super-powered being. The trio would later become the government-sponsored team, the "Terrific Trio". Magma became the group's most disenchanted member, due to his grotesque appearance. During a successful hostage rescue, Magma realized how much he had lost upon seeing the fear in the face of the little girl he had just saved. The frustration of not being able to touch his loved one, combined with the sense of confinement, Magma broke into Dr. Hodges' lab and stole their latest DNA scan. While he hauled himself away, Batman intercepted him, but the hero was no match to the superior strength of Magma.

Magma then headed back to the Trio Tower and showed his teammates proof that their DNA was deteriorating. At that moment, the Tower was attacked by General Norman, who was pulling the plug on the whole project. Magma punched his way out to the hangar, where the Trio used an aircraft as a decoy while they escaped underground.

The Trio confronted Hodges with the proof of his involvement in the accident. Out of grief, they tried to replicate it, destroying the city if necessary. When Batman tried to appeal to Magma's heroic side, he retorted that he was no hero but merely an accident, because he was never given a choice. Magma prevented Batman from hitting the abort button, and blocked Hodges' way out. Then, Batman doused him with water, causing his magma makeup to solidify. Magma presumably was killed or captured.
