Little is known about the man who became Powderkeg. He was a mercenary hired to steal high-tech circuitry for Brazilian crime lord Kristina Ramos. He ran afoul of Captain Marvel (Monica Rambeau) who had thought she lost her powers after stopping a mutated Marrina. She encountered Powderkeg and used her new powers to defeat him.
Powderkeg fought the Avengers during a failed mass prison escape occurring at the Vault. During the incident, he followed the lead of the breakout, Venom. Teamed with Mentallo and Vermin, they temporarily defeated Iron Man and Hank Pym. The entire breakout was soon neutralized by technological means, with energy pumped through Mentallo.
Powderkeg was later recruited by Doctor Octopus to join his incarnation of the Masters of Evil during the Infinity War. The Masters of Evil confronted the Guardians of the Galaxy in the Avengers Mansion. Everyone became embroiled in a fight against evil doubles of both teams. Magus, the villain behind the Infinity War, had recruited an army of superpowered doubles to defeat and absorb Earth's superpowered resistance.
At some point, Powderkeg was again captured and imprisoned, where he later teamed up with a number of other captured villains against the She-Hulk, although they were defeated.
Powderkeg later appeared as one of the patrons of a bar catering to villains, and years later was caught by Aero after trying to steal antiques from Myanmar.
