Thermite

Thermite burst onto the scene in 1986's Squadron Supreme #10, a creation of the legendary Mark Gruenwald and Paul Ryan during one of Marvel's most ambitious Copper Age projects. With only a handful of catalog appearances, this is a rare, deep-cut character whose value lies precisely in that exclusivity — sharing pages with the likes of Hyperion, Mink, and Stanley Stewart within Gruenwald's richly imagined alternate universe. Collectors hunting the corners of the Squadron Supreme saga will find Thermite a compelling piece of that world, preserved in the celebrated Gruenwald Omnibus and even catalogued in Official Handbook of the Marvel Universe: Alternate Universes 2005 — a mark of genuine canonical standing. If you love the texture and ambition of that landmark series, Thermite is exactly the kind of discovery that rewards a deep dive.
