2. Dust (128 Points, 2 first place votes)
Dust is a mutant from Afghanistan. She was taken into captivity by slave traders who planned to sell her off as a mutant slave. When her capturers attempted to remove her headdress she lashed out at them, turning into her Dust form and stripping the flesh from their bodies. It was Fantomex who initially discovered her to rescue her. Wolverine had also been out to locate her, and assisted in killing the remainder of her would-be capturers and getting her to the safety of X-Corporation headquarters in Mumbai. While Wolverine was sleeping and allowing himself to heal she turned into her dust form, hiding all around the room. Jean Grey recognized telepathically that she was there and attempted to comfort her, but she would only say one thing: Turaab (meaning "Dust").
While at the Xavier institute, she befriended and joined the Hellions. Instead of wearing a traditional X-Uniform, she decided to keep her traditional clothing, an abaya and a niqab.
She was placed in Xorn's and when he asked her to join his new group and she refused, he controlled her dust form and forced her to destroy Cerebra.
Ater the effects of M-Day, Dust was one of the few students who didn't lose their powers. The depowered students and staff were sent home; however their bus was bombed by anti-mutant religious zealot Reverend William Stryker. Subsequently, Emma Frost had the surviving students engage in an all-in brawl, with those deemed to be the best performers assigned to a new team of trainee X-Men. Dust was among those students who made the grade.
Sooraya became a target of William Stryker's crusade against the Xavier Institute. Icarus gave her a note, which X-23 told Sooraya not to trust. When Icarus visited the church of William Stryker he was shown why Dust was his next target. Nimrod had a vision of an altered future in his memory banks which showed Dust killing all the Purifiers by turning into a sand storm and ripping the flesh from their bones. After entering the church of Reverend Stryker, she was shown being shot down, though it was revealed to be X-23 dressed in one of her burquas. When Stryker's team infiltrated the school, Dust reappeared, surprising Stryker and playing a key role in defeating his Purifiers.
Dust helped fend off Belasco, which she does for a while with Mercury. While fighting Belasco, he states that her dust form is resistent to magic, as is her friend Mercury's mercury form.
Dust fought the Hulk with the other New X-Men in World War Hulk: X-Men. She was quickly taken out by the Hulk when he lifted a pipe from underground, spraying her with water.
During Messiah Complex, Dust stays behind, choosing not to take part in attacking the Purifiers without permission. She then helps in the final battle taking out Exodus, the leader of the Acolytes with help of Emma Frost
After the X-Men "disbanded", Dust returned to Afhganistan, and as seen in the first issue of the new series, Young X-Men, protects a small village from invading members of the Taliban. She is then recruited onto the new team along with old friends such as Rockslide by Cyclops.
