Kylo Ren

Kylo Ren, born Ben Solo, also known as Darth Tantrum or Darth Vader Jr. and often mistaken for Darth Revan, was a human male Sith Lord wannabe  who lived approximately thirty years after the Battle of Endor and the son of Han Solo and Leia Organa. He wore a black hood, cloak and a dark mask, because he wanted to be like his grandpa and Revan. He wielded a lightsaber of a special design which projected a main red blade, with a red cross guard projected out of its sides. He is well known to destroy expensive pieces of equipment when he's angry.

Biography
As a child Ben loved history and his favorite person from history was Revan. Originally he liked the light side Revan but then one day all his history books simply vanished as if there was no history at all. Ben got really pissed and turned to the Dark side and started a Sith Cult where he murdered many people and blew up some planets.

Behind the Scenes
Kylo Ren was created because Disney thought nobody liked the EU, then when they heard a character named Revan was super awesome and everyone wanted him to be canon they said “Oh shit we need to make a character that looks like that guy Revan, but we cant let anyone know that's what we did”
