Phasma

Phasma, a human female stormtrooper captain of the First Order, grew up as a member of the Scyre clan on the nuclear-ravaged world of Parnassos, where she became a formidable warrior, eventually becoming the clan's military leader. Seeking passage offworld, Phasma helped the First Order General Brendol Hux find his ship, in the process betraying her own brother, Keldo, and the rest of her clan. After being rescued, Phasma joined the First Order, abandoning her former life.

Over the years, Phasma rose through the ranks of the First Order, eventually becoming the leader of their stormtrooper training program. She conspired with Brendol's son, General Armitage Hux, to assassinate her former benefactor, resulting in Brendol's former protege, Cardinal, attempting to kill her after the assassination was carried out. Having consolidated her position within the First Order, Phasma became part of an unofficial triumvirate consisting of Armitage and the dark warlord of the First Order, Kylo Ren.

As a senior officer, Phasma commanded First Order forces in their struggle against the Resistance, and, under orders from Supreme Leader Snoke, their search for a galaxy map that would lead to the last of the Jedi, Luke Skywalker. During the search, Phasma participated in a massacre at one of the many villages on Jakku, an atrocity which eventually inspired a First Order stormtrooper named FN-2187 to defect to the Resistance.

Following the Hosnian Cataclysm, Phasma was ambushed by FN-2187, alongside the smugglers Han Solo and Chewbacca, at Starkiller Base and was subsequently forced to let down the base's shields, eventually resulting in the base being obliterated. Surviving the subsequent battle, Phasma framed Lieutenant Sol Rivas for the base's destruction and led a mission to hunt him down after he had discovered the truth. During the pursuit of the Resistance fleet, Phasma once again fought FN-2187, now named Finn, aboard the First Order flagship Supremacy, which had recently been devastated by a hyperspace ramming. During the battle, Finn and his companion, Rose Tico, were able to overpower Phasma, resulting in her falling to her death, plunging into a fire that was consuming the stricken ship.
