Polaris Real Name:  Lorna Dane (this is the name her adoptive parents gave her.  Her real name has not been revealed)
Height:  5'7"
Weight:  115 lbs
Hair:  Light Green
Eyes:  Dark Green
First Appearance:  X-Men (Vol 1) #49
Mutant Powers:  Polaris has the ability to manipulate magnetism.  Although she has the potential to use her powers in all the ways that Magneto does, her powers are not as strong as Magneto's.  It should be noted though, that she has not trained in the use of her powers as much as Magneto.  Polaris can levitate metallic objects or create force fields to suspend people or objects or to prevent them from harm.  She can also overload or short-circuit electrical circuits.  With concentration, she can perceive the world around her in terms of magnetic and electrical auras.  She can also use this ability to identify people by their magnetic auras.
History:  Lorna's parents are said to have died in a plane crash only weeks after she was born.  She was adopted by the Dane's, who are said to be her uncle and aunt.  She was never told of her true parents as it was thought this would traumatize her.  She did not learn the truth about her parents until she was nearly twenty years old.
    Lorna was born with green hair, which her foster parents dyed brown, so she would not be thought of as different.  She also had the latent ability to manipulate magnetism, but due to a genetic anomaly, would not have been able to use these powers.  However, following the intervention of Samuel "Starr" Saxon, this was changed.
    Saxon had constructed a robotic copy of Magneto, who was believed to be dead at the time, and a small army of androids with strange powers.  He planned to use this androids to accumulate wealth, while the world believed them to be mutants.  Saxon decided he needed some real mutants to lead this army, while he remained behind the scenes.  He recruited the hypnotic mutant Mesmero, and decided a mutant with magnetic powers would be very useful in controlling his robotic army.  He acquired a "psyche-generator" similar to the X-Men's Cerebro.  Mesmero used this machine to summon mutants with latent powers, the nearest of which was Lorna Dane.
    She was captured and placed in a genetic stimulator, which altered her genetic make-up to allow her to access her magnetic powers.  While she was undergoing these changes, Mesmero brainwashed her to be sympathetic to the false Magneto's cause.  She became convinced that she was Magneto's daughter and had inherited her powers from him.
    Mesmero dropped his mind control of Lorna, assuming she would follow her father under any circumstances.  However, when the X-Man Iceman revealed to Lorna her true parents origin and their plane crash, she joined the X-Men in battling Mesmero and Magneto.
    Lorna and Iceman formed a relationship, though she later fell in love with Alex Summers (Havok).  While neither of them wished to live a life as super heroes, they discovered they had a mutual interest in geophysics, and began doing doctoral research into the subject.  Spending most of their time out of the view of the public, Lorna no longer bothered to dye her hair.  Neither Lorna or Alex have ever been full-time members of X-Men, though they were both willing to help the team in an emergency.
  Polaris seems to have a natural weakness against mental domination, having been controlled by Mesmero, Davan Shakari (a Shi'ar agent) and Malice (a member of the mutant assassins the Marauders).
    Later, she encountered her alleged sister, Zaladane, a sorceress from the prehistoric Savage Land.  Zaladance stole her mutant powers, which lead to Lorna developing alternative powers including superhuman strength and durability.  She also gained considerable height and mass during this period.
    She eventually regained her magnetic powers, and returned to the United States, resuming her relationship with Havok.  Here they joined the government sponsored team X-Factor, where they both served until Havok was believed to be killed in a plane explosion, which lead to the disbanding of the team.
    Lorna believes that Havok is still alive, and recently encountered the X-Men after a run-in with the alien shape changing race, the Skrulls.
