Avengers #206

« Fire in the Streets »: An industrial saboteur, seemingly killed by his own bomb to ensure his silence, instead becomes the superhuman Pyron the Thermal Man. The bomb starts a chemical factory fire that even the Human Torch fails to extinguish. When the Avengers try to penetrate the blaze, Iron Man is frozen into immobility by his armor’s cooling units, and the Vision must remain intangible to survive the heat. Their teammates battle Pyron, who plans a huge gas explosion that would destroy his former employers and most of New Jersey, until the Wasp hurls a chemical foam capsule into his face, negating his powers.
