Ulik

Ulik is a villain that fights the Marvel superhero Thor.

History
Ulik is the strongest and fiercest Rock Troll. He was born millennia ago in Asgard. Other than that, not much has been revealed of his early history. The only other information known about Ulik is that his parents are known to be killed by Frost Giants, and Ulik has watched over his brother Horth ever since.

Thor met Ulik when the Troll King Geirrodur's attempted takeover of Asgard. While that was happening, Ulik attempted to steal Thor's hammer for the Trolls.
