Like the other Children of the Vault, Fuego was not a homo superior (mutant) or homo sapiens sapiens (regular human being) but the member of a completely different human species that had evolved biologically, culturally, and technologically over the course of six thousand years. His people's advanced technology allowed him to have superhuman abilities in the form of a special suit he wore; once the battery ran out, however, he'd be powerless.

He was able to create and manipulate fire. He took great pleasure in burning people alive.

Although he'd previously absorbed Iceman's energy, apparently "killing" him, Fuego froze to death when Iceman pulled himself back together and froze him.
