[8] Lorna Dane debuted in The X-Men #49 (October 1968),[9] created by writer Arnold Drake and artist Jim Steranko.

When the X-Men attempted to rescue her, Magneto revealed himself as the leader of the group behind her abduction—and, more importantly, claimed to be Lorna's father.

[39] For the most part, Lorna and Alex remained in civilian life for a number of years, settling in New Mexico and completing their college degrees.

Temporarily regaining control of her own mind, Lorna was able to place a phone call to the X-Men in Australia for help, but they arrived too late.

[49] Shortly after her arrival, Lorna joined the Muir Island X-Men team formed by Moira and former X-Man Banshee.

The Shadow King used Polaris as a gateway to allow him access to the physical world from the astral plane, causing a worldwide increase in anger, hatred, and violence in the process.

[54] Polaris was then asked to join the newly formed X-Factor by Valerie Cooper, and, tired of hiding out on Muir Island, she accepted.

[65] After recovering from her injuries, and learning that Havok's "terrorist" activities had been a front for his true undercover work, Polaris forgave him, although she rejected him romantically.

However, during their first team meeting, she could only watch as Havok was seemingly killed in the explosion of a faulty time machine constructed by the mutant from the future, Greystone.

During the encounter, Magneto, another member of The Twelve, discovered that he could use Lorna to tap into the Earth's magnetic field with incredible force, effectively hiding the reduced state of his powers at the time.

Magneto launched a full-scale assault on Carrion Cove, the last city opposing his rule, to gain access to technology that would restore his full abilities.

[71] Although Quicksilver was discovered and forced to leave Genosha, Polaris maintained a low profile to covertly transport refugees from the war to other nations, as well as monitor Magneto's actions.

[75] When Polaris rejoined the X-Men, the extremely traumatic experience had left her with a darker, more ruthless personality, even killing some members of the anti-mutant Church of Humanity.

Havok broke up with Polaris after they were about to be married, leaving her at the altar for nurse Annie Ghazikhanian with whom he had an affair while he was in a coma using telepathy.

Polaris eventually was forced by circumstance to accept that her powers were gone and admit the fact to the rest of the team—whereupon all the other members of her squad, except her would-be-paramours Iceman and Havok, revealed to her that they had already guessed it.

She then left the mansion with Havok to "search" for her lost powers, irrationally convinced they lay with an alien named Daap, a seeming twin to the deceased X-Statix member Doop, who she had seen on a recent mission in space.

[84] After being rescued from an anti-Apocalypse cult by the new team, Polaris agreed to join Professor X, Darwin, Havok, Marvel Girl, Nightcrawler, and Warpath on their mission to stop Vulcan.

Polaris seemed to finally show concrete signs of forgiving Havok, telling him to "just shut up and kiss me" after the team won their first battle against the entire regiment of Shi'ar soldiers in their beginning struggle against D'Ken and in support of Lilandra.

[85] Although Havok initially rebuffs her advances, hesitant to "start up again after" everything that happened between them, Lorna says that he needs to "blow off some steam" and the scene ends with them kissing.

[89] Polaris and the Starjammers played a large role in the War of Kings storyline, which also featured Vulcan, The Inhumans, Nova, and The Guardians of the Galaxy.

As the energies of the two planets inched closer to impact cascade and send chaos through the streets, Magneto and Polaris are taking the fight to this "other" Earth, battling the parallel Sentinels sent after them.

[106] During the Secret Empire storyline, Polaris breaks in on a prison in New Tian when Havok is about to attack the time-displaced Jean Grey and Jimmy Hudson.

[109] Polaris is seen with Magneto as he explains the process of resurrection for mutants involving the combined powers of The Five (Hope Summers, Goldballs, Proteus, Eva Bell and Elixir).

[122] Maite Molina of ComicsVerse noted the popularity of Polaris among comic book fans, saying, "She does not believe there is a point in one’s heroic journey where you have to establish yourself.

"[123] Lukas Shayo of Comic Book Resources called Polaris one of the best female X-Men characters, writing, "Lorna Dane is a force to be reckoned with in the field, and she is remarkably creative with her powers.

"[124] Polaris was the winner of a popularity contest held by Marvel Comics in 2021,[125][126] which served to determine who would be the final member of a new X-Men team that would debut during the Hellfire Gala storyline.

Polaris, Quicksilver and the Scarlet Witch were considered royalty in this reality, and Lorna eventually develops a close relationship with her father.

[133] Polaris is framed for killing dozens of people with her powers during a rescue mission, and imprisoned in the Triskelion of the Ultimates with mutant terrorist Magneto.

Originating from Earth-8149, she is seemingly killed in battle with a group of Sentinels engineered to destroy her, but is plucked out of time moments before her death to join the Exiles.

[137] In the end Polaris finds out Magneto her father has turned to the side of good because of her death to avenge her murder at the hand of Sentinels.
