Lorelei wonders if she has made a mistake, but Loki assures her that she will succeed where her older sister, Amora the Enchantress, has failed.

Fafnir instead hypnotizes Lorelei, and places her in a trap near the workplace of Thor's alter-ego, Sigurd Jarlson.

Thor, as Jarlson, finds and rescues the unconscious Lorelei, and fights Fafnir until the dragon flees.

He falls asleep and Lorelei exits the apartment, leaving a note offering to cook dinner for him next weekend.

At her apartment, she is changing into something comfortable when Jarlson takes a phone call and suddenly has to leave, turning into Thor in a nearby alley.

Melodi answers a knock on the door and is kidnapped by Malekith the Accursed, ruler of the Dark Elves of Svartalfheim.

Malekith reveals his deception and demands that Thor bring him the Casket of Ancient Winters in exchange for Melodi's return.

Malekith has managed to open the Casket, so with winter raging around them, Thor, Lorelei, and Willis return to Earth.

Loki has Lorelei drink the elixir of Lofn; when Thor inhales it, he falls so deeply in love with her that he does whatever she says.

[15] Amora tries to educate her sister on love and not to waste it after Daillus storms her castle to see if Lorelei is really as beautiful as everyone says and she turns him to stone.

The Destroyer (which, unknown to Sif and Balder, is occupied by Lorelei's soul) stops them, declares that it has overthrown Hela, and attacks them for having mortal forms.

She prepares to unleash its ultimate power of disintegration, but is delayed when she accidentally collapses a wall on to herself,[21] and Sif and Balder escape.

Kurse sees Thor; believing him to be Malekith, he calls forth dead monsters from Hel and Nifleheim to attack him.

[25] While Amora and the other the Asgardian gods work to recover their true identities, Seth restores Lorelei to life.

Amora begs Lorelei's forgiveness for not being a very good older sister, and releases her from Seth's spell, destroying her body.

[27] In Asgard, Pluto, Lord of Hades, promises Lorelei earthly power and dominion if she wields a spell to create a Valkyrie for him.

Pluto manipulates the magic and transforms Lorelei into a Valkyrie as well, and sends her to Earth with little memory and unable to speak.

The two fight to gain control over the Valkyrie while the Defenders destroy Pluto's temple, allowing his denizens of the dead to pour through to Earth.

Asgardian flesh and bone is about three times denser than similar human tissue, contributing to her superhuman strength, durability and endurance.

In battle against Seth and his minions, she was depicted as firing mystical force bolts, similar to her sister's.

[30] Lorelei's great beauty and seductive manner enable her to persuade virtually any male god or mortal to do whatever she wants.

After Loki defeats Thor, reduces all the gods to their knees, and becomes the new master of Asgard, Lorelei returns to the castle and wants payment for helping him achieve his newfound status.
