Star Wars - Episode VII: The Force Awakens
Captain Phasma is the commander of the Stormtrooper squad that accompanies Kylo Ren to Jakku in search for the missing part of the map leading to the location of Luke Skywalker, who has not been seen for almost thirty years. Her stormtroopers attack swiftly, rounding up the villagers and burning down their huts. After Kylo Ren murders the village elder Lor San Tekka, Phasma asks how they should fare with the villagers. Ren tells her to kill them all and Phasma gives the order, causing her stormtroopers to murder every villager. However, stormtrooper FN-2187 does not participate in the massacre. After returning to their flagship, Phasma speaks to 87, who is having a panic attack and took off his helmet. She tells him to have his blaster checked, referring to him not following her orders on Jakku, and tells him to put his helmet back on.

After FN-2187, now known as Finn, has deserted the First Order she is called before General Hux. She tells them that it was the first time that Finn defied orders and that no one could have expected this betrayal. Phasma is present when Hux addresses the First Order before using Starkiller Base to destroy the Hosnian System.

When the Resistance later starts their attack on Starkiller Base, Han Solo, Chewbacca and Finn infiltrate the base to shut down the base's shield generator. As none of them has an idea how to do that they ambush the next best stormtrooper who turns out to be Finn's old captain Phasma. Finn mocks her for him now being the one in control and they force her to deactivate the generator. To prevent her from alarming anyone, Han, in reminiscence on his adventures on the Death Star, proposes to throw her into the base's trash compactor which the group supposedly carries out.

Phasma was found and evacuated before the destruction of Starkiller Base and the planet.

Personality
Like every stormtrooper Phasma is very loyal to the First Order and follows orders without question. She has no tolerance for disobedience and questioning orders. She bashes her stormtroopers even for petty acts like removing their helmets.
