No, Obi-Wan Kenobi never wielded a purple lightsaber in the Star Wars canon. Throughout his appearances in the films, television series, and novels, he consistently used blue-bladed lightsabers, which represent his role as a Jedi Guardian. The purple lightsaber is famously associated with Mace Windu.
During his years as a Jedi, Obi-Wan Kenobi fought with three lightsabers. His first had a blue plasma blade and a hilt similar to that of his master, Qui-Gon Jinn. Obi-Wan used this weapon until Darth Maul kicked it into a deep shaft on Naboo. He then constructed a new, blue-bladed lightsaber with a similar design.
Mace Windu's lightsaber emitted a purple blade. As one of the most notable members of the Jedi Order, Jedi Master Mace Windu carried a Jedi lightsaber distinguished by its unique purple plasma blade. Its distinctive color served as warning to adversaries that the Jedi Order's greatest champion was ready to fight.
The rarest lightsaber color is arguably black, embodied by the unique Darksaber created by the first Mandalorian Jedi, Tarre Vizsla, with only one ever existing; however, white (Ahsoka Tano's purified crystals) and purple (Mace Windu's) are also exceptionally rare, symbolizing unique paths outside the typical Jedi/Sith dichotomy.
The Origins of Mace Windu's Purple Lightsaber
Essentially, it allowed Windu to place immense focus and concentration on the fault lines of the Force and perceive different possibilities and their results, providing him a glimpse into the future and the consequences of actions.
Form VII (Juyo), the "Ferocity Form," was banned by the Jedi Order because it required channeling aggression, anger, and other intense emotions to fuel its wild, relentless, and unpredictable attacks, which closely skirts the dark side and risks corrupting the user, a direct violation of the Jedi Code's emphasis on peace and emotional control, even though Mace Windu later adapted it into the controlled Vaapad variant for a select few.
Tràkata is a rare and cunning lightsaber technique built on deception and misdirection. Jedi like Kao Cen Darach and Cal Kestis used it to gain surprise advantages in battle, while Sith like Qimir mastered its lethal precision.
Mara Jade, with her iconic magenta lightsaber, stands as a pivotal character in the Star Wars expanded universe.
In 19 BBY, the lightsaber was lost when it was dropped out of the window of Supreme Chancellor Palpatine's office prior to his death. In 18 BBY, Duros salvagers recovered it and sold it to Senator Sano Sauro.
The Acolyte's sixth episode reveals Qimir was once a Jedi, making him a formidable dark side user.
By the time of the New Sith Wars, the Sith Blademaster Kas'im had mastered Form III as well as the six other forms. Kas'im trained several apprentices in the style, including Fohargh, who used it against Bane's Form V. Bane himself possessed considerable skill in the Form, training his apprentice, Darth Zannah, in it.
Usage and history
Jinn used this lightsaber until the Battle of Naboo, where he was mortally wounded by the Sith Lord Darth Maul. Qui-Gon's apprentice, Obi-Wan Kenobi, then used the same lightsaber to defeat Maul after losing his own. After the battle, the weapon was later returned to the Jedi Temple.
Form VI, or Niman, is a balanced lightsaber style that blends previous forms into a practical, Force-integrated combat method. Used by Jedi like Cin Drallig, Anakin Skywalker, and Sith like Darth Sidious, it emphasizes harmony, adaptability, and moderate bladework.
So: which lightsaber is the most powerful? The answer depends on what you value most: the devastating raw power of Kylo Ren's unstable blade, the symbolic might of Anakin Skywalker's blue saber, the balance reflected in Rey's yellow lightsaber, or the legendary authority behind the Darksaber.
Darth Maul is the weakest. Bane was strong : he killed all the Sith and lots of Jedi.
In Star Wars lore, Order 37 was a grim Clone Trooper contingency plan to capture a wanted individual (often a Jedi) by taking a civilian population hostage, locking down the area, and threatening mass execution if the target wasn't surrendered, making it a horrific tactic used by the Empire to force Jedi compliance. It was considered more brutal than Order 66 because it targeted civilians directly, forcing Jedi to often turn themselves in to save innocent lives, as seen on planets like Bellassa.
Darth Sidious
We'll start things off with the most powerful Sith in the Star Wars universe. Darth Sidious has been a character in many storylines over the years, most notably in the Old Republic comic books.
Both Exar Kun and Ulic Qel-Droma were Sith and used non-red lightsabers (blue and green if I remember correctly), as depicted in the Legends Tales of the Jedi comics.
The Ghostfire Kyber Crystal is one of the rarest in the galaxy, known for crafting silent, nearly invisible lightsabers with ghostly afterimages. Found in remote Outer Rim peaks, it features in Star Wars Legends as a weapon of stealth and illusion.
