Burner was recruited by Magneto alongside four other mutants which included Lifter, Slither, Peeper and Shocker. Magneto and Captain America responded to a newspaper ad that stated a mutant needed sensitive persons or agencies equipped to help provide a home environment and care. Both men met a man that had possessed a tiny, minute mutant he called Mister One inside his wrist watch. Magneto attempted to steal this mutant because it possessed great mental abilities but came into conflict with Mister Two who was Mister One's bigger protector. Magneto returned back to his base and told his mutant band his plan to steal the tiny mutant and called it Operation Grab. Burner and the rest of his fellow mutants attacked Mister Two and Captain America when they were outside the SHIELD medical facility. Burner displayed his mutant ability to induce combustion by surrounding Captain America and Mister Two in a ring of fire. Burner and the rest of the group retreated when SHIELD members appear but it allowed Magneto the diversion he needed to steal Mister One from the SHIELD medical lab. Burner would engage with Captain America and Mister Two when they infiltrated Magneto's lair. Burner ignited Mister Two with his powers and killed his foe when it suffocated to death. Mister One activated a bomb where Burner and the rest of Magneto's mutant squad had disappeared after the explosion.
After Magneto abandoned his team they re-named themselves Mutant Force, Mandrill employed the team in order for them to help aid him in his planned to dominate the U.S. During this they battled Valkyrie, Hellcat, Wasp, Yellowjacket and Nighthawk. Burner then fought the Hulk with Mutant Force, after being enlisted by the government into government service. The group then changed into The Resistants and Burner changed his name into Crucible.
