Captain Phasma: Who is she?

Captain Phasma is one of the storm trooper captains for the First Order in Star Wars: The Force Awakens. Leading up to the release of the movie, the hype seemed to be very high for this character. Once the movie came out, fans noticed that Phasma did not make many appearances or do much of anything important to the plot of the movie. The purpose of this post is to fill in for the lack of detail provided by the film about Phasma. Hopefully I can answer the question, Who is Phasma?

Captain Phasma is a female captain for the First Order. Her first appearance in the Star Wars movies was in the most recent addition, The Force Awakens. She worked as an unofficial commanding triumvirate for the First Order and their Starkiller Base. She took command of the stormtrooper soldiers of the First Order. Phasma serves alongside Kylo Ren and General Hux in their struggle against the "Resistance". Under orders from Supreme Leader Snoke, Phasma found herself on Jakku. She, alongside Kylo, attacked a small village called Tuanul. After capturing Poe, Phasma orders her storm troopers to kill the survivors. After this encounter on Jakku, Phasma is seen again when the stormtroopers unload off of the transport. She tells Finn, the newly introduced stormtrooper character, that he is to submit his blaster for inspection. She also scolds him for taking off his helmet without permission. After Han Solo and Chewbacca infiltrate Starkiller base, they take Phasma captive and force her, under the threat of death, to lower the base's planetary shield. Han Solo asks Finn if there is a trash compactor, referencing his incident with the trash compactor in episode four. It is believed that Phasma was left in the trash compactor before the destruction of the base.
