In canon, there are only two characters more powerful than Darth Vader: Luke and
In Star Wars Legends and Canon, Galen Marek (Starkiller) is the only Jedi (other than Obi-Wan Kenobi) to put a beat down on Darth Vader/Anakin Skywalker.
This might be a bit of a controversial pick at just number three, but Darth Vader, perhaps the best-known Dark Side user, is not the most powerful Sith ever. Born Anakin Skywalker, Vader became an extremely powerful Jedi Knight, one who was prophesized to be the "Chosen One" who would bring balance to the Force.
Like Vader, Darth Revan started as a Jedi Knight, being the most powerful Jedi of the time, before switching over to the Dark Side of the Force, becoming an unstoppable Sith who practically purged the galaxy of his enemies. While their stories are similar, Darth Revan went even further than Vader.
Vader, the only power who overrules him is papa Palpatine.
Jedi Master Yoda is the most powerful of them all. This should come as no surprise, as he was the head of the Jedi Order in the prequels and was revered for his abilities during the original trilogy. Yoda's power is unmatched and was a real threat to Darth Vader and the Imperials.
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.
Yoda will most likely win in a fight against Darth Vader because he is more skilled with a lightsaber and has the experience and feats that allow him to trim whatever size and strength advantage Darth Vader has over him. In fact, Yoda nearly defeated Palpatine, something that Vader could never do.
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%.
As the first Dark Lord of the Sith, Ajunta Pall founded the first Sith Empire and expanded it onto other worlds. The Sith took over the planet Ziost and created it as their capital and as Pall's new home.
1. Obi-Wan Kenobi. Of all today's characters, Anakin's own Jedi Master most notably conquered the newly-fallen Sith Lord at the height of his power, before his need for movement-restricting armor.
Within the Star Wars Legends continuity, Yoda's Jedi instructor was N'Kata Del Gormo, a Hysalrian Jedi Master, according to an in-universe legend.
His armor could be hacked and controlled by a device. In a turn of events, Darth Vader's right limb holding his dangerous scarlet lightsaber was moving of its own accord toward his neck. This was a dangerous weakness indeed. We have seen the abilities of top slicers like Tech in The Bad Batch and DJ in The Last Jedi.
He can't use the Force against Thanos' mind, and he definitely won't prevail in a fight in the Marvel Universe if Thanos has the Infinity Gauntlet, but the Force will provide Darth Vader safe insurance. In the end, Thanos' neck is only as strong as his skin.
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.
Anakin Skywalker is the son of Shmi Skywalker, born without a father through the Force. He is the secret husband of Padmé Amidala, the father of Luke Skywalker and Leia Organa, the father-in-law of Han Solo, and the maternal grandfather of Ben Solo.
A Sith Lord with the ability to cheat death and create life, Plagueis is the mentor of Sheev Palpatine / Darth Sidious, who, in accordance to the Sith's Rule of Two, eventually betrays Plagueis by murdering him in his sleep, taking his place as Sith Master.
The added risk Darth Vader takes in allowing children to live in a situation where he could have killed them proves that he regrets killing Younglings and will avoid harming any more children for the rest of his days, though intense intimidation is a dark strategy to avoid repeating his Youngling massacre.
Rey is the protagonist of The Lego Star Wars Holiday Special, set the Life Day after the events of The Rise of Skywalker. Now a Jedi Master, Rey unsuccessfully attempts to train Finn as her Padawan after having recognized him as Force sensitive.
He wasn't even eligible. In order to be granted the rank of master, a Jedi Knight must first train their own. Padawan to knighthood. When their Padawan became a Knight, they would then be able to attain the rank.
