Enhanced Abilities: Inferno has upper level super human strength, durability and endurance.
Heat Generation: Inferno can increase the amount of heat he radiates at will, and can project molten steel from his body. He also appears semi liquid and can allow bullets to partially pass through. Due to the Uru flake imbedded within Inferno's right palm he is also endowed with Mjolnir's energy re-directing properties and can also absorb and re-direct electrical energy such as he did with Iron Man's armour.
A worker at a Pittsburgh steel mill once visited by Thor. Joseph Conroy found a flake of the Thunder God's magical uru hammer, incorporating it into a good luck charm keychain. Damaged battling the Destroyer, this fragment of Mjolnir was accidentally left behind when the mortal forges were appropriated in its repair.
Falling under Maggia control a few years later, Conroy threatened to expose the mill's crooked puppet boss, Mr.Paretta, to the police. Paretta ordered another employee to push Conroy into a vat of electrified, white-hot liquid metal. Originally thought incinerated, Conroy's ever-present uru chip instead mutated him into a superhumanly strong creature composed of flaming molten "living slag", capable of radiating intense heat and draining energy from available sources.
