In the aftermath of the Battle of Exegol, Rey buried the famed lightsaber alongside Leia Organa's lightsaber, on Tatooine, the desert homeworld of Anakin and Luke.
There, Rey unveiled her finished, single-bladed weapon after burying the two lightsabers of her mentors, Luke Skywalker and Leia Organa, at the ruins of the Lars homestead—the former place of residence of the Skywalker family.
Skywalker used the green lightsaber to defeat his father, Darth Vader, on the second Death Star. That night, he turned himself in to the Endor Imperial garrison at their base, and the lightsaber was confiscated by the Imperial officer, Commander Igar. The weapon was then given to his father, Darth Vader.
Luke Skywalker used to wield a green lightsaber before declaring himself a Jedi, so he nearly killed his father. After deciding to stop using the green lightsaber, he finally chose to put it away. After the king died, he rediscovered it. This saber weighs about the same as the older version of the lightsaber.
Whereas Obi-Wan buried both Anakin's and his own lightsaber, Rey buried Luke's and Leia's while creating a new one for herself. She lived in a different era, when Jedi light was re-emerging and she had nothing to fear. Her decision to bury Luke and Leia's lightsabers was an attempt to give them a new legacy.
That Rey finishes her arc with a yellow lightsaber is noteworthy. The Sentinels who made the color famous were masters in both combat and Force use, were often excellent spies, and made for exceptional defenders of the Jedi order.
She wielded it in defeating Kylo Ren, then brought it to Ahch-To and offered it back to Luke. When he refused it, Rey carried the ancient weapon herself. The lightsaber sheared apart when Rey and Kylo struggled for possession of it aboard the Supremacy, but Rey reforged it as she continued her Jedi training.
After losing his father's lightsaber on Cloud City, Luke Skywalker constructed a replacement with a green plasma blade, its hilt similar to that of Obi-Wan Kenobi's weapon.
However, this has fans questioning why Luke returned to his blue lightsaber for his confrontation against Kylo Ren in The Last Jedi. After losing his hand, Luke's lightsaber was replaced by his green one in Star Wars: Return of the Jedi.
During his final duel with Grievous, Kenobi lost the lightsaber but eventually reclaimed it when it was given back to him by Clone Commander CC-2224 "Cody." He would also use this lightsaber to duel his fallen apprentice Darth Vader on Mustafar and would continue to wield the weapon during his exile on the planet ...
It's because of his mastery of sorsue (sorry for my bad spelling.) Well if you want the ACTUAL reason it because in the original 3 films the Green Light Sabre didn't exist until after Obi Wans death.
The lightsaber's redesign was a byproduct of the bleeding process that damaged its kyber crystal, rendering it dangerously flawed and unstable, and necessitating the lateral vents were meant to prevent the cracked kyber crystal from overloading.
In The Last Jedi, during Rey and Kylo Ren's confrontation in Snoke's throne room, Luke's original lightsaber was split in half, and as shown later on in the movie, the crystal had been divided too, but in The Rise of Skywalker, which takes place one year after the previous movie, Rey is shown to have rebuilt it.
Anakin's lightsaber also acted like a vergence when Rey came into contact with it, granting her insights from the past when she touched it in the Takodana Castle. The Skywalker lightsaber served as an heirloom of the Skywalker family passed from father to son and later to the last Skywalker, Ben Solo.
A crystal embodies the Jedi as the heart of the lightsaber, and pure kyber has no color until it's bonded to the Force user. This process likely resulted in Rey Skywalker's lightsaber being yellow.
At the end of the film, Rey returns to Luke's home on Tatooine, where she buries Luke and Leia's lightsabers, then reveals her own—decked out with a golden-yellow blade, a hilt that looks like it might've been crafted from her staff, and a cigarette-lighter-looking switch that turns it on.
Leia Organa's lightsaber was a blue-bladed lightsaber powered by a kyber crystal in the core of the hilt. It was silver and copper in color and featured mother-of-pearl inlays. Organa's weapon was considered a work of art, having an elegant symmetry with silver and gold hues that evoke to her upbringing on Alderaan.
Luke Skywalker eventually had the lightsaber in his possession after Yoda's death in 4 ABY. Five years later, he offered the weapon to Grogu in a choice against obtaining beskar armor. However, Grogu chose the beskar armor over the lightsaber and went back to Din Djarin.
Encased in a distinctive silver-and-copper hilt, Leia's lightsaber used a naturally-occurring blue kyber crystal, much like Luke's original saber that he had inherited from his father by way of Obi-Wan Kenobi.
After his sacrifice, it is mentioned that the caretakers on Ahch-To took care of Luke's possessions, including his "weapon". This suggests that, despite not making an appearance, the green lightsaber is in their possession – at least during The Rise of Skywalker.
The main reason for the change was that during the filming of Return of the Jedi, the crew realized that the blue saber did not look right during the battle with Jabba the Hutt. When shot in daylight, the blue would blend with the color of the sky, so George Lucas and his crew decided to make the change.
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. With the advent of the Great Jedi Purge, the blade again fell into the possession of Kenobi, who went into hiding on the planet Tatooine.
By the end of The Rise of Skywalker, Rey had become the last known Jedi of the Skywalker Saga.
The fate of Luke Skywalker's old lightsaber appeared to be symbolic of his philosophy; it was shattered in a Force tug-of-war between Rey and Kylo Ren. Even its Kyber Crystal was broken.
confirmed that what Finn wanted to tell Rey was that he's force sensitive!" Abrams apparently revealed Finn's Force sensitivity after the Q&A, when fans "wanted to talk and take pics," ren clarified in a follow-up tweet. When "one person asked about what Finn wanted to say," the Force-sensitivity answer "is what J.J.
