After Count Dooku severed the right arm of Anakin Skywalker in the opening battle of the Clone War, a mechno-arm was grafted to what was left. Luke Skywalker had much of one grafted to his wrist after Darth Vader severed his hand at Cloud City.
Many fans declare that Luke won the confrontation because he nearly killed Vader, but that's technically not true. Vader was far more powerful than Luke and easily could have bested him. So, knowing that Vader wasn't allowed to kill Luke drastically changes the equation.
History. Like many Jedi did for hundreds of years, Yoda built his lightsaber under the aegis of Professor Huyang, an architect droid who had been with the Jedi Order since its nascent days. As a first step, Yoda acquired a kyber crystal from the icy caverns of Ilum, a mission that proved to be very eventful.
After Anakin Skywalker fell to the dark side and became Darth Vader in Star Wars: Episode III - Revenge of the Sith, he and Obi-Wan Kenobi had their climactic battle on Mustafar that resulted in Vader losing all his limbs and suffering severe burns throughout his entire body.
Did Dooku feel bad about cutting off Anakin's arm?
Count Dooku was not sad after cutting off Anakin's arm in Episode II: Attack of the Clones (AOTC). He was ready to kill Anakin, and only the entrance of Yoda spared the Jedi's life.
While thought to have been lost in Cloud City, the lightsaber was salvaged from the mining colony's industrial depths and eventually found its way to Maz Kanata.
Ahsoka's white lightsabers first appeared in the TV episode "Fire Across the Galaxy", the season one finale for Star Wars Rebels. According to Dave Filoni, one of the show's creators, the lightsaber blades are white to reflect her non-affiliation with the Jedi or Sith.
At the end of "The Rise of Skywalker," Rey reveals her own lightsaber, which is a bright yellow color. This was a surprise and got people interested in its origin and significance. Rey's lightsaber is unique, not just because of its color, but also because of its cool design, including a rotating part.
Over the course of the series, Luke recognizes in Mara an underdeveloped affinity for the Force; and although she initially resists Jedi training, she eventually becomes a Jedi Master. Luke and Mara develop a strong bond in Zahn's The Hand of Thrawn duology; he proposes marriage, and the two wed in Michael A.
The implication is clear - that this is Luke Skywalker at his peak, equal in power to Darth Vader but a champion of the light nonetheless - but Star Wars is yet to confirm that this was indeed the case.
Obi-Wan faced off against Darth Vader four times and physically beat him twice while beating him through his Force development in a third fight. Obi-Wan Kenobi had the high ground that led to Vader's disfigurement and becoming the ultimate Star Wars cyborg.
