Demon Bear

A monstrous supernatural entity manifesting as a massive demonic bear, this creature had a dark spiritual connection to New Mutant Danielle Moonstar, haunting her with a deeply personal threat rooted in her Native American heritage.

Few villains in Marvel's Bronze Age arrived with the raw, primal dread that Demon Bear brought to The New Mutants #3 in 1983, courtesy of Chris Claremont and Bob McLeod. This lurking supernatural menace has haunted Marvel's pages for over four decades, crossing from the formative early days of the New Mutants into the darker corners of titles like Uncanny X-Force and Deadly Neighborhood Spider-Man, sharing those shadowed adventures with the likes of Wolfsbane, Roberto Da Costa, and even Peter Parker himself. With appearances stretching all the way to 2026, Demon Bear is no footnote — it's a persistent, brooding presence that refuses to stay buried. If you're drawn to the stranger, more gothic edges of the Marvel Universe, this is exactly the kind of creature worth tracking down.
