- "You'll see Iron Man rendered obsolete. By the next generation in offensive weapons. By me... the Melter!"
Bruno Horgan was the owner of a start-up robotics company and developed a suit similar to Iron Man's Iron Man Armor. Horgan's presentation to military officials was a failure, as the power source of the suit literally melted it, and later chances to show his creation were negated, even after claiming his creation was finally ready.
Sometime after the Battle of New York, Horgan attacked Iron Man during a press conference in front of the Stark Tower. After a quick victory Horgan announced that he would be selling the designs of his technology in a few days.
Two days later Horgan attacked, and with some effort, secured a victory over War Machine, leading both Stark and Rhodes to confront Horgan together. Horgan was promptly defeated and placed into U.S. military custody.
