Inferno

Inferno is a Marvel villain who debuted in the 1999 one-shot Juggernaut #1, operating alongside similarly named threats including Conquest, Tempest, Decay, and Stonecutter. The group clashed with the Juggernaut and crossed paths with the Avengers.

Bursting onto the scene in 1999's Juggernaut #1 courtesy of Joe Casey and Terry Shoemaker, Inferno is a Modern Age Marvel creation with a footprint that stretches across nearly two decades. Though their catalog appearances are select rather than sprawling, this character has rubbed shoulders with a striking cast — Conquest, Tempest, Decay, and Stonecutter among them — and earned a place in the pages of Avengers and Avengers Assemble, Marvel's premier superhero real estate. The kind of character who rewards the deep-diving collector, Inferno even merited an entry in the All-New Official Handbook of the Marvel Universe A to Z, a sure sign that the House of Ideas considers them worth cataloguing for the ages.
