Ulik

Ulik is the mightiest of the Rock Trolls, a fierce subterranean race native to the realm of Nornheim who have long warred with Asgard. Driven by hatred of the gods and an insatiable hunger for conquest, he repeatedly challenges Thor as the champion of his brutish kind.

Few villains in the Thor mythos hit as hard — literally — as Ulik, the fearsome Rock Troll who first crashed onto the scene in Thor #137 in 1967, conjured into existence by the legendary Silver Age duo of Stan Lee and Jack Kirby at the height of their cosmic Marvel mythmaking. Born into a pantheon of gods, monsters, and warriors, Ulik has spent nearly six decades as one of Asgard's most persistent and formidable threats, sharing pages with Thor Odinson, Odin, Sif, Loki, and even Iron Man across titles like Thor, Avengers Next, and Marvel Knights. With 70 catalog appearances and a key-issue credit to his name, he's no mere footnote — Ulik is a cornerstone bruiser of Marvel's mythological corner, the kind of classic antagonist that keeps collectors and fans coming back to those Kirby-crackled pages again and again.
