Corruptor

Jackson Day was a chemical plant worker whose exposure to experimental compounds gave him the power to corrupt others' minds through skin contact, bending them to his will — a dangerous ability that brought him into conflict with the Hulk and other Marvel heroes.

Crawling out of the Bronze Age Marvel universe in The Incredible Hulk #263 (1981), brought to life by the legendary creative team of Sal Buscema and Bill Mantlo, Corruptor is one of those deliciously dangerous figures who makes the Marvel universe feel genuinely unpredictable. Over nearly four decades of appearances — spanning The Incredible Hulk, Invincible Iron Man, and New Avengers — this villain has crossed paths with some of Marvel's heaviest hitters, sharing pages with Spider-Man, Captain America, Hawkeye, and Ms. Marvel. With 14 catalog appearances and a key issue to their name, Corruptor may not be a household name, but that's precisely what makes discovering them such a rewarding deep dive for the dedicated collector who loves unearthing the Bronze Age's most compelling corners.
