1. Emperor Palpatine. Darth Sidious infiltrated the heart of the Republic and twisted it into the Empire, sparked a terrible war that engulfed the entire galaxy in fire and ash, corrupted once-noble Jedi to his cause, and executed Order 66 to erase the Jedi Order from existence.
Sheev Palpatine was often considered the embodiment of evil and Star Wars' main antagonist.
Emperor Palpatine
As is made plain throughout the original and prequel trilogies, Palpatine is pretty close to the ultimate big bad. He's such a major force hanging over all of Star Wars, in fact, that he was ultimately brought back in Rise of Skywalker.
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.
In the film's climax, Maul duels Qui-Gon and his apprentice Obi-Wan Kenobi (Ewan McGregor). He is able to kill Qui-Gon and knock Obi-Wan down a shaft, but Kenobi propels himself out of the pit and uses Qui-Gon's lightsaber to bisect Maul, sending the two parts of his body falling down the shaft.
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.
It was Barriss herself who orchestrated the bombing and framed Ahsoka. Anakin dueled Barriss on Coruscant, and eventually placed her under arrest. Brought before a military tribunal led by Governor Tarkin, she admitted her guilt, but held steadfast in her belief that the Jedi and Republic had lost their way.
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%.
With an athletic build, an exotic beauty, and blue skin, Aayla Secura stood out among the many faces of the Jedi ranks. A cunning warrior and Jedi Knight during the rise of the Clone Wars, Aayla fought alongside Clone Commander Bly on many exotic battlefields.
They have a grudge against each other because, well, let's face. Mace Windu was not pleased to see Anakin at the Jedi Council Chambers in The Phantom Menace. He disliked the idea of letting a young boy join the order. And from then on, he never exactly created a bond with Anakin Skywalker.
Pretty Friendly: Darth Vectivus
He became aware of his Force adept abilities, and his power to conjure phantoms led him to the Sith path. He became an apprentice of Darth Millennial, but maintained his code of ethics throughout his Sith teachings.
Darth Plageuis is one of the most famous Sith Lords in the Star Wars Universe. Plageuis was the mentor and master to Darth Sidious, and he was spoken of to Anakin in Star Wars: Revenge of the Sith.
Galen was secretly trained as a Sith Lord apprentice to Vader, but returned to the light side and the Jedi. Galen Marek is the only one who came close to destroying the Sith Lord, thanks to his vast knowledge of Vader's fighting tactics through the many hours they trained together.
Vader still killed Obi-Wan, but it was described in much more detail than Vader just simply cutting down Obi-Wan. This was the passage: “[Vader] lunged forward, feinting, and then slashing in a deadly downward arc with the saber. It struck home, cutting Kenobi cleanly in half.”
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.
Obi-Wan Kenobi lacked that Lucas feel from the moment it began, and few shots really stood out to viewers. Additionally, the lightsaber battles lacked the emotion and weight of the Original Trilogy and the incredible choreography in the Prequel Trilogy.
The clear answer for the smartest Jedi of them all is Master Yoda. This mysterious but beloved character comes from a species about which very little is known, and has survived through many eras, stretching back to the High Republic.
If we're to come to a definitive decision on who the strongest Jedi ever is then we have to consider more than their physical skills and strength. Master Windu could be the strongest Jedi ever, he's strong, trained, wise and proved his abilities in combat as well on the Jedi council.
The term "Sith Lord" generally encompassed members of both sexes, although some female Sith such as Lumiya, Tahiri Veila, Olaris Rhea, and Vestara Khai were styled Sith Lady. Originally, "Sith Lord" referred to a high-ranking member of the Sith Order's society.
