"Let the past die. Kill it, if you have to. That's the only way to become what you are meant to be."
The son of Han Solo and Leia Organa, Ben Solo was seduced by the dark side of the Force and renamed himself Kylo Ren, becoming the First Order’s champion and Supreme Leader Snoke’s student. Ultimately Ren was determined to extinguish the light side within himself and destroy the last traces of the Jedi Order, fulfilling the legacy of his grandfather, the Sith Lord Darth Vader.
The Force was strong with Ren; in addition to his Jedi training and knowledge of arcane dark side lore, the bloodline of the most powerful Jedi and Sith flowed through his veins. He was the embodiment of conflict due to his immersion in both sides' teachings, but it was through discord that he derived power, channeling anger into strength. The master of the Knights of Ren, he conquered much of the galaxy during his reign as Supreme Leader of the First Order.
He eventually renounces his adopted persona of Kylo Ren and is redeemed.
