Midgard Serpent

The Midgard Serpent — drawn from Norse mythology as Jörmungandr, the massive world-encircling serpent and offspring of Loki — is one of Thor's most ancient and formidable foes, a colossal beast whose very existence is bound to Asgardian prophecy.

Few creatures in Marvel's cosmos carry the mythological weight of the Midgard Serpent, the colossal beast that slithered onto the page in Thor #127 back in 1966, conjured by the legendary duo of Stan Lee and Jack Kirby at the very height of the Silver Age. Born from the same thunderous creative partnership that reshaped superhero mythology, this ancient terror has haunted the pages of Thor for nearly six decades, sharing its dark corner of the Marvel universe with the likes of Thor Odinson, Loki, Odin, and the warrior Hogun. With at least one key collector's issue to its name and appearances stretching all the way to 2023, this is a character whose presence signals that the stakes have been raised to a truly cosmic scale. If you love Marvel's mythological grandeur at its most primal, the Midgard Serpent is an icon worth seeking out.
