Kylo Ren’s helmet was a combat helmet worn by Kylo Ren, the master of the Knights of Ren who turned to the dark side of the Force after renouncing his place in the Jedi Order. Patterned on the battle gear of the Knights of Ren, the helmet’s theatrics granted Ren a more imposing appearance and concealed his former identity as Ben Solo, son of Han Solo and Princess Leia Organa. He removed his helmet upon encountering his father, who entreated Ren to turn away from the dark side, during the Battle of Starkiller Base. Ren, who struggled to resist the pull to the light side of the Force, killed his father in hopes of completing his journey to the dark side. However, this act of patricide failed to impress his master, Supreme Leader Snoke of the First Order, who saw Ren’s actions as a sign of petulance rather than strength.

Displeased with his apprentice’s failings, Snoke insulted Ren’s helmet and ordered him to remove it. He berated Ren for becoming emotionally unbalanced, to the point where he was defeated by Rey, a Jakku scavenger with no prior experience in lightsaber combat. Having lost the approval of his master, who now regarded Ren as weak, sentimental and unworthy of his grandfather Darth Vader’s legacy, Ren destroyed his helmet in a fit of rage and plotted to regain the status he lost as a result of his duel with Rey. However, the helmet was ultimately repaired sometime after Ren’s ascension as Supreme Leader and the Battle of Crait.
