Kylo Ren, portrayed by Adam Driver, is one of the most complex characters in the Star Wars saga. A key element of Kylo Ren’s identity is his distinct crossguard lightsaber. The weapon itself reflects the internal struggle and chaos that defines the character. Unlike the traditional, stable blades of the Jedi or Sith, Kylo Ren’s lightsaber stands out for its volatile design and fiery instability. This weapon is not just a tool of combat; it is a symbol of Kylo Ren’s fractured nature.
The Construction of Kylo Ren’s Lightsaber

Kylo Ren’s lightsaber is unique within the Star Wars galaxy. Constructed using an unstable kyber crystal, the blade emits a fiery red hue, indicative of the dark side of the Force. Unlike most lightsabers, which have a smooth and consistent energy flow, the blade of this weapon flickers violently, as if it is barely being contained. This instability is a result of the cracked kyber crystal housed within the hilt.
The lightsaber features a distinctive crossguard design, with two smaller blades, known as quillons, emerging from vents on either side of the main blade. These quillons are not ornamental; they are exhaust ports that redirect the excess energy generated by the fractured crystal. The unique design is both functional and symbolic, representing the volatile and destructive path that Kylo Ren has chosen.
The Kyber Crystal’s Origins
Kylo Ren’s lightsaber was not constructed from scratch. The hilt originally belonged to an earlier Jedi weapon, which Kylo Ren modified after embracing the dark side. The kyber crystal inside the lightsaber was bled, a dark side ritual that involves pouring negative emotions into the crystal to turn it red. This process cracked the crystal, causing the instability that defines the weapon. The fractured crystal mirrors the internal conflict that Kylo Ren experiences throughout the Star Wars sequels.
A Connection to the Past

The lightsaber’s hilt design is an ancient one, tracing its origins back to the Old Republic era. Crossguard lightsabers were once used by Jedi and Sith as far back as the Great Scourge of Malachor. Kylo Ren’s weapon revives this ancient design but adapts it to function in a modern context. This connection to the past reinforces Kylo Ren’s obsession with legacy and his determination to emulate his grandfather, Darth Vader.
However, unlike Darth Vader’s weapon, Kylo Ren’s lightsaber is raw and untamed. The fiery, unstable blade reflects a sharp contrast to the polished and deadly precision of Vader’s crimson lightsaber. This distinction highlights Kylo Ren’s inability to fully live up to the legacy he idolizes.
The Role of the Lightsaber in Kylo Ren’s Journey
Kylo Ren’s lightsaber is not just a weapon; it serves as a narrative device that evolves alongside its wielder. During the events of Star Wars: The Force Awakens, the weapon is used to convey Kylo Ren’s ferocity and impulsiveness. The chaotic blade mirrors the rage and emotional instability that drive the character. In key moments, such as the confrontation with Han Solo on Starkiller Base, the lightsaber becomes an extension of Kylo Ren’s inner turmoil.
In Star Wars: The Last Jedi, the weapon continues to symbolize the conflict within Kylo Ren. The raw, unstable energy of the blade reflects the push and pull between the light and dark sides of the Force. This duality is further emphasized during the throne room battle, where Kylo Ren briefly allies with Rey to defeat Supreme Leader Snoke’s guards. The lightsaber, with its unpredictable energy, embodies the tension between these conflicting loyalties.
Kylo Ren’s Lightsaber Form and Combat Style

The lightsaber is wielded with an aggressive and unrefined combat style. Drawing from Form V: Djem So, Kylo Ren’s technique emphasizes raw power and relentless strikes. Unlike the fluid elegance of Jedi masters or the precision of Sith Lords, Kylo Ren’s fighting style is brutal and chaotic. The crossguard design adds an extra layer of lethality, allowing the quillons to be used for parrying and inflicting additional damage.
The weapon’s instability affects combat as well. The unpredictable energy of the blade makes it dangerous not only to enemies but also to the wielder. This inherent risk underscores the recklessness of Kylo Ren’s approach to both combat and his own identity.
Symbolism and Legacy
Kylo Ren’s lightsaber is more than a tool of destruction; it is a reflection of his journey and inner conflict. The weapon’s fiery instability mirrors the constant struggle between light and dark within its wielder. Unlike the refined weapons of the Jedi or Sith, this lightsaber feels unfinished, raw, and chaotic—just like Kylo Ren.
Adam Driver’s portrayal of Kylo Ren adds depth to the symbolism of the lightsaber. The weapon becomes a visual representation of the character’s fractured psyche and his attempts to forge a path in the shadow of the Skywalker legacy. Whether on Starkiller Base, in the throne room of Snoke’s ship, or on Exegol, the lightsaber is a constant reminder of Kylo Ren’s internal battle.
The legacy of Kylo Ren’s lightsaber lives on as a symbol of conflict and chaos in the Star Wars saga. Its distinctive design and unstable blade continue to captivate, standing as a testament to the complexity of its wielder.
