Chemistro

Chemistro is a Marvel villain who wields an alchemical gun capable of transmuting matter, using it to commit crimes and clash with heroes including Iron Man, Spider-Man, and others. The Chemistro identity has been used by multiple characters in the Marvel universe.

A Marvel villain born in the Copper Age, Chemistro made his mark debuting in Iron Man #251 in 1989, the creation of the legendary Dwayne McDuffie and Herb Trimpe. Over nearly three decades, this character has crossed paths with some of Marvel's heaviest hitters — Spider-Man, Wolverine, Captain America, and Ms. Marvel among them — popping up across landmark titles like New Avengers and Invincible Iron Man. A relatively rare presence in the catalog, Chemistro is exactly the kind of deep-cut Marvel figure that rewards the curious collector willing to dig past the A-listers.
