Kylo Ren (Ben Solo)

Kylo Ren (real name Ben Solo) was the founder of the Knights of Ren and skilled in the Dark Side of the Force, along with being the son of Leia Organa and Han Solo. Leia and Han sent Ben to train with Luke Skywalker and become a Jedi, but he betrayed Luke and he and his Knights of Ren massacred Luke Skywalker's new Jedi Order. Ben then joined the Dark Side, being trained by Supreme Leader Snoke. He was named Kylo (by Snoke) of the Knights of Ren, which quickly became Kylo Ren. He aimed to finish what his grandfather Darth Vader (Anakin Skywalker) started, and to destroy the Jedi. Kylo Ren was tempted by the Light Side, but took the last step to the Dark, slaughtering his father, Han Solo. During the Battle of Starkiller Base, he severely injured Finn in a lightsaber battle; he was then defeated in a lightsaber duel by the force-sensitive scavenger Rey, but was thought to escape with General Hux before Starkiller Base exploded.
