Most likely not commonly known by many casual Star Wars is that, at least in Legends, the Sith had their own “chosen one” prophecy and that the central figure in it was believed to have been the Sith Lord, Darth Bane.
Anakin Skywalker. That's right, the Sith Chosen One is (ironically) the Jedi Chosen One. After all, Anakin did sort of fulfill the prophecy by destroying both the old Jedi and Sith Orders, but he didn't rebuild a new Sith Order from the ashes.
By removing Palpatine's control over the Force, its balance was finally restored – and that meant Rey was the chosen one and it was never Anakin Skywalker (and nor was it Luke, as was sometimes argued). It was only ever Rey, the granddaughter of Palpatine.
Emperor Palpatine / Darth Sidious.
Even though Kylo Ren uses a red lightsaber, harnesses the dark side of the Force, and wears a cape, he is not a Sith. Because of that, he can never hold the title of Darth.
Truly, the most powerful Sith Lord was Darth Sidious, better known in his public persona of Chancellor (later Emperor) Palpatine. Through cunning and manipulation, Sidious killed his master to claim the mantle of Dark Lord of the Sith.
N'Kata Del Gormo was a Force-sensitive male Hysalrian Jedi Master who lived during the times of the Galactic Republic. According to legend, he found and trained Yoda and a Force-sensitive Human friend.
Move aside, Anakin Skywalker. 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%.
Qui-Gon Jinn discovered Anakin Skywalker, the prophesied Chosen One, during the fall of the Galactic Republic. Forty-one years before the Battle of Yavin, Shmi Skywalker gave birth to a son named Anakin Skywalker.
After the Sith were decimated by the Jedi Knights of a thousand years ago, Bane enacted the Sith rule of two: there would be only two active Sith at one time -- a Dark Lord to embody the power, and an apprentice to crave it.
By the time of the One Sith, the "Darth" title was reserved only for those who proved their power and their unquestioning loyalty to Darth Krayt.
By 44 ABY, the true Sith species in the Empire were believed to have gone extinct due to the interbreeding process. Characteristics shown would be determined depending on how much Dark Jedi or Sith blood an individual possessed due to interbreeding.
Anakin Skywalker was a living vergence in the Force, and as Darth Vader he was a force to be reckoned with. But was he more powerful than Luke? As powerful as Darth Vader may be in Star Wars, he pales in comparison to his son, Luke Skywalker.
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.
Aftermath. Although Order 66 greatly depleted the Jedi Order's ranks, with an estimated less than 100 Jedi surviving it, it was only the beginning of the Great Jedi Purge, which stretched on for years and claimed the lives of many of the survivors of the initial onslaught.
He died of old age on Dagobah. Fans of Jedi Master Yoda likely know that he retains much of his power even after passing into the Living Force.
But one Jedi stands above the rest and needs to start getting recognized as the greatest Jedi who ever lived. That is none other than Obi-Wan Kenobi. While this saga is ultimately the story of the Skywalkers, Obi-Wan is arguably the best and most pure Jedi to ever come out of it.
Evidence for ROTS Anakin > Yoda (in the force)
Sidious then confirms that Anakin is 'far' more powerful. Anakin's quick work of Dooku + Sheev's confirmation immediately make it clear that Anakin is a tier above Dooku power wise when he cuts loose.
The very first Jedi in Star Wars canon is a nameless figure known as the Prime Jedi. He was likely the builder of the first Jedi Temple on Ahch-To, seen in The Last Jedi. According to the Star Wars: The Last Jedi: The Visual Dictionary, the mosaic of stones in the chamber of the Temple depicts the Prime Jedi.
Though he saw Anakin's potential, Yoda could not ignore the danger inherent in Anakin's unrestrained emotional attachments. To teach Anakin responsibility, Yoda assigned Skywalker a Padawan learner: Ahsoka Tano. Yoda knew there would come a time when Anakin had to let go of Ahsoka.
A Sith Lord with the ability to prevent 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.
Luke Skywalker
However, once Luke fully embraced his power in Star Wars: Return of the Jedi, he proved that he was indeed stronger than Darth Vader and struck his father down.
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. Galen was secretly trained as a Sith Lord apprentice to Vader, but returned to the light side and the Jedi.
