Kylo Ren / Ben Solo

Ben Solo, formerly known as Kylo Ren, is the central antagonist of the Star Wars sequel trilogy, later turned into the deuteragonist during the events of Star Wars: The Rise of Skywalker. He is also the protagonist of his own comic mini-series released by Marvel Comics, set six years before Star Wars: The Force Awakens, telling the events leading to Ben's fall to the dark side. Ben is the son of Han Solo and Leia Organa, the nephew of Luke Skywalker, and the grandson of Anakin Skywalker/Darth Vader and Padmé Amidala. After turning to the dark side, he becomes the apprentice of Supreme Leader Snoke, and later renames himself Kylo Ren upon becoming the Master of the Knights of Ren. Kylo Ren wields a unique crossguard lightsaber that he constructed himself, being the rival of Armitage Hux and a leading member of the First Order under his master's guidance. Throughout the sequel installments, he develops an intimate and intricate relationship with the protagonist Rey, as they progressively fall in love with each other despite being enemies. She is later revealed to form a dyad in the Force with him. In Star Wars: The Last Jedi, he kills his own master to save her life, and takes the title of Supreme Leader of the First Order for himself. In The Rise of Skywalker, his parents' and Rey's love and forgiveness bring him back to the light, and he fights beside Rey in the final battle against the revived Emperor Palpatine.
