Ben Solo was a human male Jedi Padawan and the primary antagonist of the sequel trilogy. He was the son of smuggler and Rebel Alliance General Han Solo and Rebellion leader Princess Leia Organa, and the nephew of Jedi Master Luke Skywalker, having been born shortly after the Galactic Empire's defeat. As part of his uncle's new generation of Jedi, Ben trained under him, but was eventually seduced to the Dark Side by Supreme Leader Snoke, a puppet created by a revived Emperor Palpatine / Darth Sidious, the last Sith, and sought to become a Sith Lord, as powerful as his late grandfather, Darth Vader (Anakin Skywalker). Following the destruction of Luke's New Jedi Order, Ben adopted the Kylo Ren persona and became a commander within the First Order, as well as the leader of the Knights of Ren, an organization of fellow Force-wielders. He later killed his father when he unsuccessfully tried to redeem him, and formed a unique connection with Rey, the last Jedi and Palpatine's secret granddaughter, called a "dyad in the Force". After killing Snoke, Ren took over as Supreme Leader of the First Order, until ultimately being redeemed by his mother, who died in the process, and helping Rey face Palpatine, giving his own life to save hers.
