"None may challenge Hela's will."

..." Thou must hand him to me, for he is MINE."

The Goddess of Death, Hela has become one of The Mighty Thor's most enduring foes. She has also occasionally allied herself with (and fought against) other Marvel villains such as Loki, Mephisto, Amora the Enchantress and Thanos, as well as played an antagonist role to such Marvel heroes as The Avengers, the Guardians of the Galaxy, the New Mutants, and Angela.

Hela first came to the Allfather Odin's attention when the Norns (the three Goddesses of Fate) warned him that she would pose a great threat to the Nine Realms. Odin, in response, cast her down to Hel and appointed her as the Goddess of Death when she reached majority. Since that time she has frequently come into conflict with both Odin and his son Thor as she has schemed and plotted to conquer Valhalla, Asgard, the Nine Realms and even the universe as a whole.
