Kylo Ren's lightsaber

Kylo Ren's lightsaber was a lightsaber built and utilised by Kylo Ren approximately thirty years after the Battle of Endor. The lightsaber had a main red blade, as well as two smaller red blades that projected from the side of the weapon as a crossguard. The lightsaber's blades have a different energy form compared to other blades, as the blade funnels like fire and static electricity instead of solidifying. Kylo used this weapon while working with the Knights of Ren and the First Order.

Behind the scenes
Kylo Ren's lightsaber was introduced in the first teaser trailer for Star Wars: Episode VII The Force Awakens. The 88-second trailer, released on November 28, 2014, showed Ren walking through a snowy forest and igniting the lightsaber. The introduction of the lightsaber was well-publicized in the media, including on The Colbert Report and @Midnight on Comedy Central. The lightsaber was also the subject of a number of pieces of fan art released in the days after the trailer premiered.

It appeared twice in the second trailer that debuted at Celebration Anaheim 2015. The trailer showed Ren swinging the lightsaber, and later holding it in his left hand while he holds out his right, as if he was ordering an attack.

The concept of a crossguard lightsaber was first introduced in Star Wars Legends, previously known as the Expanded Universe. The lightsaber, which had two beams rather than three, made its first appearance in the 2004 comic Star Wars: Republic 61: Dead Ends.
