Lorelei is a femme fatale Asgardian seductress from the Marvel Cinematic Universe. She was portrayed by Elena Satine.
Lorelei is an Asgardian with the power to enslave the wills of men through the sound of her voice. She was previously imprisoned in Asgard, and a collar placed around her neck to prevent her from speaking. When the Dark Elves attacked Asgard, she was able to escape her prison and make her way to Earth through one of Loki's hidden portals.
Lorelei arrived in Death Valley, California, and took control of newly wed Jimmy McKenzie. He took her into Nevada, where she took the Dogs of Hell motorcycle club under her spell. The bikers took Lorelei to their hangout, a bar in the Nevada desert, where she amassed a small army of enthralled bikers and Nevada State Troopers. Her servants committed robberies throughout the area, hitting jewelry stores and gun stores to outfit her growing army.
Lorelei's actions caught the attention of S.H.I.E.L.D., who sent out a team led by Phil Coulson, further aided by the Asgardian warrior Sif. Although she lost all of her servants in the ensuing battle, she took one of S.H.I.E.L.D.'s agents, Grant Ward into her spell, and the pair rode away from the bar to Las Vegas, where they ended up having sex.
When Coulson had her hotel room in Caesars Palace raided, Lorelei and Ward infiltrated his plane, taking scientist Leo Fitz under her spell as well. As no one knew she was on the plane, or that Fitz was under Lorelei's control, he tricked Sif and locked her in the Cage. From there she was ejected through the dorsal airlock.
Although the S.H.I.E.L.D. agents on board tried to stop her, Lorelei made her way to the Cage to retrieve Sif's sword and the collar that made her powerless. However, Sif had been clinging to the outside of the plane, and after re-entering the Cage, fought Lorelei to a standstill, ultimately holding her nemesis with her sword to her neck. Refusing to go back to prison, Lorelei attempted to goad Sif into killing her by reminding her of how she took pleasure in using Sif's former lover, only for Sif to place the collar around her neck. Silenced, Lorelei's spell over Ward and Fitz was broken. Per Odin's orders, Sif took Lorelei back to Asgard alive.
