In Star Wars Canon, only Luke Skywalker can be acknowledged as the one who truly defeated Darth Vader.
Because he was not an active member of the Jedi Order during Order 66, Infil'a escaped execution. Some time later, he faced the Sith Lord Darth Vader. Infil'a put up a fierce fight against Vader, almost killing him by throwing the already damaged Sith Lord off of a cliff.
Only one person could defeat Darth Vader once and for all. The spirit of Anakin Skywalker, long dormant, finally rose and overcame the dark side. While his body failed him, Anakin rose once again and defeated the Sith once and for all. Both Sidious and Vader met their ends that day, at the hands of Anakin Skywalker.
Vader, the only power who overrules him is papa Palpatine.
Vader's toughest opponent was undoubtedly his former Jedi Master, Obi-Wan Kenobi. During their duel on the Death Star, Obi-Wan was able to match and even surpass Vader's power. The fight was incredibly intense and at the end, Obi-Wan sacrificed himself so that Luke Skywalker could escape.
In the original trilogy, Palpatine is depicted as the Emperor of the Galactic Empire and the master of Darth Vader (Anakin Skywalker).
In their climactic duel within Cloud City in Empire Strikes Back, a just-trained Luke is defeated but still manages to land a glancing blow on Vader. With some experience under his belt, Luke soundly defeats Vader a year later in Return of the Jedi, even managing to redeem his father along the way.
Vader used his pain and anger to fuel his Dark Side powers, becoming one of the most powerful Sith ever and perhaps the most feared. He was the enforcer of the Empire, using his red lightsaber and black armor to strike fear into his enemies, becoming an instrument of terror to fight the Rebels.
1 Darth Sidious
There has been no Sith, as powerful, meticulous, nor as evil as the Emperor himself, Darth Sidious. As previously mentioned, Sidious trained in the Dark Side by Darth Plagueis before Sidious killed Plagueis in his sleep, making Sidious a Sith Master.
During the early days of the Clone Wars, Skywalker served as a Jedi General in the Grand Army of the Republic, commanding the clone troopers of the elite 501st Legion against the Confederacy of Independent Systems. After receiving his knighthood, Skywalker oversaw the Jedi training of his own apprentice, Ahsoka Tano.
Darth Vader's Insecurities are His Biggest Weaknesses
In the end, virtually all who have made the attempt to use Vader's cybernetic nature against him have ended up dead or defeated. The elite few who have had the upper hand, even before his conversion to mechanical monstrosity, have done so by dominating him mentally.
but how many total Jedi did he kill over the years? in canon, we can confirm that Vader killed at. least 22 Jedi during Operation Nightfall alone. most of these that we actually see were younglings, but he did kill several Masters, with the most notable being Shaq, Ti and Syndralic.
Aside from agility and telekinesis, Yoda could absorb and redirect Force attacks, like lightning. Because of his higher understanding, he would easily overcome Darth Vader in a fight, though that doesn't mean it wouldn't be a difficult battle.
Darth Vader : You have failed me for the last time, Admiral! Captain Piett? Captain Piett : Yes, my lord? Darth Vader : Make ready to land our troops beyond their energy field, and deploy the fleet, so that nothing gets off the system.
As Darth Vader, Skywalker was believed to have had roughly eight-tenths of the strength of the Emperor. Nevertheless, Vader wielded tremendous power and skill, enough to use the Force to overpower almost any opponent he could not defeat with his lightsaber.
Master Yoda has risen above all others to claim the top spot as the most powerful Jedi of all time and the true chosen one according to IGN's audience. He won pretty handily as well, as he was victorious in 89,756 of his 95,243 battles and had a win percentage of 94.2%.
According to Star Wars Legends content, the first Sith was a former Jedi Master, Ajunta Pall, who became a so-called Dark Jedi, or “Fallen” Jedi. As the name implies, these Force-sensitives chose to practice the Dark Side, and rejected the Light Side of the Force.
Darth Sidious, also known as the Emperor and Supreme Chancellor Palpatine, is not just the evilest Sith in Star Wars (arguably in both canon and Legends) but the evilest villain overall, deemed so thanks to his irredeemable actions throughout the Skywalker saga and surrounding content.
As Supreme Commander, Darth Vader was the ranking leader of the Imperial Military.
Of course, Anakin Skywalker/Darth Vader is remarked as the strongest force-wielding human out there. Under Sidious's tutelage, his rage and unhealthy ambition found release and he became an utterly terrifying menace to the galaxy.
Vader died defending his son, killing Darth Sidious and fulfilling his destiny as the Chosen One.
Kylo and Rey (Daisy Ridley) also blasted the Imperial Crusier open trying to Force pull the Lightsaber away from each other, so clearly, Kylo Ren is an extremely strong Force-wielder. Nonetheless, it can be said that Darth Vader is the more powerful master of the Force for one key reason: his temperament.
While Obi-Wan Kenobi was frail by the time of Star Wars: A New Hope, he was still stronger with the Force than Darth Vader.
After all, SOMEBODY had to train Luke in order to defeat Darth Vader and the rest of the Empire. So how many Jedi died during the attack? Almost 10,000—meaning that only 0.2% of Jedi survived.
