Bruno Horgan

Bruno Horgan is driven into bankruptcy when a government safety inspection team proves that he is using inferior materials, with the defense contracts awarded to his competitor Tony Stark (the alter ego of hero Iron Man). Discovering that one of his faulty devices is capable of generating a beam capable of "melting" anything composed of iron, Horgan redesigns the device so that it can be strapped to his chest, and after donning a costume adopts the alias the Melter. As the Melter, Horgan becomes a professional criminal and embarks on a campaign of industrial sabotage against Stark, hoping to ruin him, eventually encountering Iron Man after Stark is told he could lose his government contracts, though when he first met Stark he succeeded in knocking him out. Despite damaging the hero's armor and forcing Iron Man back, the Melter is defeated when Stark builds a temporary duplicate armor composed of aluminium, but leaps into the sewer, though Stark is unaware whether he was killed or not.^[7]

The Melter reappears as an employee of master villain Baron Zemo (who has upgraded the melting beam to affect all metals) as part of supervillain team the Masters of Evil. He helps spray Adhesive X over the city. The Melter meets Iron Man as the Avengers first meet the Masters, but Iron Man knocks him away using his magnetic repulsor. The Masters were defeated with the Melter being jailed after Iron Man drenches him with water, preventing his beam from working.^[8] The Radioactive Man was deported back to China, while the Black Knight and Melter are placed in a cell with bars chemically treated so they cannot be melted. The Masters of Evil have a second encounter with the Avengers after the Black Knight and Melter are broken out of jail by the Enchantress and Executioner. The Melter nearly finishes Iron Man after welding his boots to a roof, but he is stopped by Thor using his uru hammer, which the Melter cannot melt. The Masters of Evil are eventually defeated after Thor transported them and the Avengers to another dimension, with different scientific laws which meant their weapons rebounded. The villains are bound and returned to Earth.^[9] The character upgrades his weaponry and battles Iron Man once again,^[10] before reappearing as part of the next version of the Masters of Evil, although the villains are defeated when betrayed by the Black Knight.^[11] The Masters of Evil - with the Melter - also accidentally encounter the Avengers during a parade and during the battle are defeated when surprised by the superheroines the Lady Liberators.^[12]

The Melter has several battles with Iron Man: at the direction of other-dimensional villain the Black Lama, the Melter joins fellow villains Whiplash and the Man-Bull to form the team the Death Squad and attempt to kill the hero;^[13] upgrades once again and attack before being defeated;^[14] and reappears, with many other villains, as an employee of criminal mastermind Justin Hammer. At Hammer's direction the Melter and fellow villains have a series of encounters with Iron Man in an unsuccessful attempt to neutralize the hero.^[15] After another attempt to sabotage the company Stark International^[16] the character makes a brief appearance with other villains in an unsuccessful attempt to kill Fantastic Four member the Thing.^[17]

Eventually, the Melter manages to augment his melting ray's power to its peak, but before he can employ it, he is surprised and murdered by the Scourge of the Underworld, who is disguised as the villain's laboratory assistant. The Scourge destroys the latest melting ray right afterwards.^[18]

Christopher Colchiss

The second Melter character first appears in Dark Reign: Young Avengers #1 (July 2009) and was created by Paul Cornell and Mark Brooks.

Christopher Colchiss later adopts the Melter name and is recruited to lead the "Young Masters", a teenage super team opposing the Young Avengers. This Melter has inherent melting super powers and does not require artificial aids. Unlike the original Melter, his abilities also extend to humans.^[19]

Melter has serious doubts about the moral conviction of most his teammates, and twice he has made mistakes with his powers that killed people - his parents when he was young and more recently an old lady who maced him in the face thinking he was a mugger. Melter also caused a subway station to collapse by melting its supports by accident, though without causing any serious casualties. These incidents have resulted in making him extremely hesitant to use his powers in combat. Melter desires to be a hero, but is unsure just what he needs to do to be one.^[20]

Colchiss was later recruited by Mandarin and Zeke Stane to assist the other Iron Man villains in taking down Iron Man. Colchiss received an upgraded suit from Mandarin and Zeke Stane.^[21]

During the Avengers: Standoff! storyline, Melter was an inmate of Pleasant Hill, a gated community established by S.H.I.E.L.D.^[22]

Christopher was welcomed into the mutant-only nation of Krakoa and given a clean slate. For unknown reasons, he began destroying parts of the island trying to spy on council meetings coming into conflict with Professor X. Despite claiming he only wanted to help him and his nation and being given two warnings, he was thrown into the Pit of Exile for breaking the "Respect the sacred land of Krakoa" law. Once in the pit, he along with the other new prisoners were greeted by its original resident: Sabretooth.^[23][24] While at first he tried to hunt them down, Third-Eye eventually used his powers to break the illusion and convince Victor that they weren't the ones he wanted to hurt, so he changed the illusion to make them all prison cellmates with Xavier and Magneto as the wardens.^[25] Sabretooth then taught the other prisoners how to channel their consciousnesses through the island to manifest themselves above-ground in artificial bodies. He sent all the prisoners on missions to recruit people to their cause except Christopher who he held back because he could sense he still felt loyalty to Xavier. Sabretooth attacked him in his mental world, then, when he was left a bloody pulp, explained his plan to him, but while he was explaining Christopher was able to gain enough control over his body to touch and melt Victor's body.^[26] The destruction of Sabretooth's body almost kills everyone in the pit because it was controlled by his mind, but Third-Eye saves everyone by dragging their consciousnesses to the astral plane while Krakoa fixes their bodies. Melter find himself in an evolved body in a recreation of Sabretooth's childhood home with the other prisoners, they find Sabretooth there waiting for them. After having dinner together they all discussed what they did to get thrown in the pit and whether they deserved to be there.^[27] Shortly afterwards they met with Cypher who informed them that Sabretooth had betrayed them and escaped The Pit on his own. He offered them their own releases on two conditions, that they take fellow prisoners Nanny, Orphan-Maker, and Toad, who had been hiding back in Sabretooth's Hell where they had originally entered from and that the assembled team hunts down Sabretooth so he can be punished for his crimes. The team of exiles then sails away from Krakoa on a boat created by Madison Jeffries.^[28]

Melter joined the other Exiles on a journey to find Sabretooth that lead to him joining them as they infiltrated a series of mutant prisons and experimentation centers established by Orchis. In this time he formed an unlikely friendship with Orphan-Maker, who due to his new look, mistook him for the Human Torch. After Orphan-Maker was kidnapped and manipulated into taking off his armor by Doctor Barrington, meaning his potentially world ending powers were no longer contained, Third-Eye took them all to the Astral Plane to buy time while Nanny and Jeffries built him a new suit. Melter had to maintain the facade that he was Johnny Storm to keep Orphan-Maker calm after he woke up thinking he was in Hell.^[29] After Nanny and Jeffries built him a new suit, the team escapes with the freed Orchis prisoners on their boat which Maddison used debris from the destroyed base to turn into a vessel big enough to contain them all. Sabretooth decides to enact one last plan for revenge against the Quiet Council by turning all the young mutant prisoners against Krakoa, he is interrupted when the team arrive at the final, underwater Orchis base and are hit by a tidal wave. During the commotion Sabretooth is again abducted by Orchis, telling his team to come looking for him before disappearing. The rest of the team, alongside Dr. Barrington and her creation are trapped in the base with the kids who instinctively attack them out of fear that they are there to perform more experiments. After Nanny shuts down the brains of everyone except herself and Orphan-Maker, the team all wake up on the ship except Nanny and Orphan-Maker, Dr. Barrington and her creation and Sabretooth who all left to pursue their own goals, Nanny and Orphan-Maker taking all the mutant babies with them.^[30]

Unnamed criminal

Roderick Kingsley later sold the original Melter costume and gear to an unnamed criminal. Melter was present with Hobgoblin (who was actually Roderick Kingsley's butler Claude) when he led his forces into fighting the Goblin King's Goblin Nation. After Hobgoblin was killed by Goblin King, Melter was among the villains that defected to the Goblin Nation.^[31]

Following Spider-Man's victory over the Goblin King, Melter was among the former Hobgoblin minions at the Bar with No Name where they encounter Electro.^[32]

During the AXIS storyline, Melter was among the supervillains that Missile Mate assembled to join the side of Phil Urich (who was operating as Goblin King) and the remnants of the Goblin Nation upon claiming that Roderick Kingsley "abandoned" them.^[34]

Melter was among the villains that appeared as a member of Swarm's Sinister Six at the time when they attacked Spider-Man and the students of the Jean Grey School for Higher Learning. After Hellion defeated Swarm, Melter and the other villains surrendered.^[35]

Melter and Killer Shrike later beat up Ringer to serve as Black Cat's warning to anyone that steals from her.^[36]

When Iron Man returns to his brownstone in his beaten-up armor, he finds that Melter has melted his Dodge Aspen and starts to taunt him. After punching Melter, Iron Man picks his body up and flies it into the sky. He tosses Melter and then rescues him much to the irritation of the bystanders.^[37]
