Polaris (Lorna Dane) is a Marvel Comics superheroine, a member of the X-Men.
A mutant, Polaris can control magnetism. She has a long-held suspicion that Magneto is her biological father. She has had a complicated long term relationship with the X-Man Havok, to whom she was engaged. As the daughter of Magneto she is the half sister of the Scarlet Witch and Quicksilver.
Created by writer Arnold Drake and artist Jim Steranko, Polaris first appeared in X-Men #49 (October 1968).
Lorna Dane met the original team of X-Men while still a student. When the villain Mesmero used his "psyche-generator" to summon mutants in North America with latent powers, Lorna found herself compelled to travel to San Francisco, where Mesmero was. There she encountered the X-Man Iceman, who tripped her with a piece of ice and convinced her to come to his apartment. Soon after she discovered the X-Men, and they in turn learned that she was a latent mutant. Mesmero and his android Demi-Men captured her and took her to their desert headquarters, with the X-Men in pursuit.
