Kylo Ren, a Force-sensitivehumanmale, was a dark side warrior who ruled the First Order as Supreme Leader during its war with the Resistance. Given the name Ben Solo, he was born in 5 ABY, one year after the Battle of Endor, on the planetChandrila to PrincessLeia Organa and GeneralHan Solo, whose busy lives left Ben with feelings of abandonment. He was a scion of the Skywalker bloodline on his mother's side, and therefore possessed raw strength in Force which ultimately attracted the attention of a dark side practitioner known as Supreme Leader Snoke. Though Organa hoped to help her son by sending him away to learn the Jedi arts under his uncle, Jedi MasterLuke Skywalker, Ben Solo's inner turmoil was exploited by Snoke in an effort to tempt him to the dark side of the Force. He destroyed his fellow Jedi students and became Snoke's apprentice as well as a Knight of Ren, and was given the moniker of "Jedi Killer" among the First Order ranks. Ren idolized his grandfather, the fallen Sith LordDarth Vader, and hoped to finish what Vader started: the elimination of the Jedi. As a leading member of the First Order, he represented its mystical side and had authority to command its armies, leading to tense competition between Ren and First Order officers, particularly GeneralArmitage Hux.

Kylo Ren was the embodiment of conflict. Ren himself strove to bury his past, though the painful experiences and emotions from his youth were nonetheless something he could channel in order to further his own power. He ultimately hoped to build an immunity to the light, and to succeed where Darth Vader failed. Like Vader before him, Ren believed it was his destiny to rule over the weaker beings of the galaxy. He idolized his grandfather, but only the dark parts of Darth Vader—not the light of Anakin Skywalker. To Ren and the Supreme Leader, it was not poor strategy or arrogance that brought about the fall of the Galactic Empire. It was the sentimentality Vader held for his son, Luke Skywalker, which led to Vader's redemption—a foolish error in judgment and a momentary lapse in an otherwise great life. Ren believed that if Vader had not succumbed to the light, the Empire would have prevailed. 

Similar to his father, Han, Ren had a sarcastic sense of humor.

Kylo ren must sound like his voice actor, Adam Driver. With or without the mask is fine. I can just edit your voice in audacity.
