Kenny Gargan was an industrial saboteur who was hired by the AIM Agenda to infiltrate Project Cadmus and sabotage their attempt to clone Super-Soldier. He managed to trigger an explosion that claimed the life of Peter Parker and prematurely awoke the clone who would go on to become Spider-Boy.
The explosion also exposed Kenny to harmful radiation and he left Cadmus with severe radiation poisoning. The AIM Agenda treated Kenny's illness with a scorpion-DNA serum before putting him in an armored containment suit (called the Scorpi-Con suit) to shield everyone around him from the radiation he was emitting.
Kenny named himself Scorpi-Con after the armor he now wore. Suffering altered percerptions due to his radiation poisoning, Scorpi-Con mistakenly believed that Spider-Boy had exposed him to the radiation, and now his mission in life is to destroy the young hero.
Scorpi-Con has the proportionate strength of a scorpion and the ability to channel his radiation into energy blasts.
Scorpi-Con's containment suit gives him invulnerability and features a cybernetic scorpion tail.
