Captain Phasma

Captain Phasma was a female individual who was the commander of a division of stormtrooper forces in the First Order. She wore a chrome stormtrooper outfit and a cloak. During the Battle of Starkiller Base, she was captured by Chewbacca and forced by Han Solo and Finn to shut down the shields on the Starkiller Base so the Resistance T-70 X-Wing pilots could attack. After that, she was dumped down a garbage chute into the Base's sewage system. It is likely she was killed in the destruction of Starkiller Base but there is a possibility she survived.
