Captain America #342
During his first mission, he joined Cobra and Copperhead as they poisoned Washington D.C.'s water suppy, turning the citizens into horrifying snake-like creatures. He and Copperhead were quickly dispatched by Captain America, but Cobra was able to escape.Boomslang continued to serve with the Society, but when he was sent to watch over Diamondback, he was confronted by Captain America. Boomslang quickly fled, but ran into a gang of teenage thugs. They shot him numerous times, and Captain America immediately brought him to the hospital. He has not been seen with the Serpent Society since, and has possibly reformed after his near-death experience.
