Geirrodur

Few villains feel as deeply woven into the mythic tapestry of Marvel's Asgard as Geirrodur, who first menaced the pages of Thor #137 in 1967 — a Silver Age debut courtesy of the legendary Stan Lee and Jack Kirby at the absolute height of their cosmic Norse world-building. Over nearly five decades, this formidable figure kept some of the most storied company in Marvel's pantheon, sharing adventures with Thor, Odin, Sif, and the fearsome Ulik across Thor, Thor Annual, and Tales of Asgard. With a key issue already marking his legacy and a presence that endured from the Silver Age well into the 2010s, Geirrodur is exactly the kind of deep-cut antagonist that rewards the curious collector — a creature of the realms who reminds you just how rich and strange Kirby and Lee's Asgard truly was.
