Emperor Palpatine, also known as Darth Sidious, is often regarded as the embodiment of evil in the Star Wars universe. His cunning manipulation and orchestration of galactic events, including the rise of the Galactic Empire, showcase his mastery of the dark side of the Force.
According to Canon, Legends, and George Lucas himself, its Darth Sidious. Darth Sidious was the embodiment of the Dark Side and in legends he is basically a god. The Rule of Two meant that each generation of Sith was stronger than the last. This means that Sidious was at that point, the strongest Sith Lord in history.
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.
The ONLY Sith More Evil Than Darth Sidious In Star Wars
Who was the nicest Sith Lord?
Though a proponent of the dark side, Darth Vectivus' self-discipline and preexisting code of ethics allowed him to remain fair and balanced without succumbing to the lure of power which plagued many of the Sith Lords who preceded him.
He regularly tortured Kreia. He destroyed planets as usual, killing billions. He destroyed Katarr. Is very abusive to Visas Marr, tormenting her to the point she had a nihilistic view on life and keeps on pleading her master of wanting to die, though he keeps her alive for his own goals.
Another contender for the weakest Sith could be Count Dooku, or has he's also known Darth Tyranus. Dooku was a cunning and talented Sith Lord, known for his swift skills with a lightsaber and his ability to manipulate populations.
Meanwhile, his flagship, the Ravager, was secretly boarded by a small force consisting of Surik, Marr, Mandalore the Preserver, and his Mandalorians. The trio confronted and slew Nihilus in the ensuing duel while the Mandalorians rigged explosives that destroyed the ship.
Darth Bane, founder of the Rule of Two, killed more Sith than any Jedi in the history of the Star Wars galaxy. Thousands of years ago, a schism among the Jedi Order led to the creation of a new faction - one devoted to the dark side of the Force.
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.
Both Vader and Dooku do commit a similar amount of crimes, with Dooku helping orchestrate the Clone Wars, resulting in the deaths of billions of beings in the galaxy, working with the Zygerrians, Wat Tambor, and Riff Tamson, whereas Vader slaughtered the majority of the Jedi including the younglings and aided Sidious ...
In Legends, out of the few that did return to the light, almost none stayed that way. In canon, we have no current examples of this. There are only a few Sith that ever converted back to the Jedi after becoming a Sith. That list in Legends is pretty much just Revan, Vader, and for a brief time, Luke.
Few Sith were as haunting and terrifying as Darth Nihilus, a Sith Lord who was almost an apparition, rather than a man. He barely spoke, preferring instead to communicate through the Force, which made him almost impossible to reason with.
Who was the nicest Sith lord (legends and Canon allowed)? Meet Darth Vectivus. He was a director of a mining company before closing it due to his concern for his workers' well-being.
If we are just talking intelligence and nothing else these are probably the smartest sith Lords. All of the following had the reputation as being acedemics or intellectuals darth plagueis the wise, Darth Sidious, Obviously Darth Traya, Revan, Marka Ragnos, Naga Sadow and vitiate.
Sha'a Gi's appearance and personality were based on Shaggy from the Scooby-Doo franchise, a fitting choice for a Jedi who gave in to fear. Sha'a Gi lacked Force awareness, physical ability, and an enduring spirit, making him the weakest Jedi in the Star Wars franchise.
Palpatine seems to have taken the most join in the suffering of others. Vitiate was evil and monstrous but it was more often then not for his own goals.
Emperor Vitiate was a Sith Lord who successfully gained near immortality by draining the life force of an entire planet, later attempting to drain all life in the galaxy, which would give him true immortality.
A dark side warrior with a mysterious past, Kylo Ren was neither Jedi nor Sith, but a product of both sides' teachings. Once an apprentice of Luke Skywalker's, he killed his fellow students and drove Skywalker into exile, becoming a First Order warlord and servant of Supreme Leader Snoke.
Darth Nihilus gets beaten by anyone who knows how to resist drain or possesses significant speed. While Powerful Nihilus is massively a one trick pony. His drain is his saving grace but without it he's have trouble with plenty of people. Palpatine himself would dominate Nihilus in virtually every single way.
Nihilus used an aggressive fighting style, mastered several dark side abilities, and could drain the life from Vader if given the opportunity. He would also have the advantage if the two fought on a world strong in the Force.
Darth Nihilus was a Human male who reigned as a Dark Lord of the Sith during the era of strife following the Jedi Civil War. Before becoming a Sith Lord, he lost everything during the Galactic Republic's war against the Mandalorian Neo-Crusaders.
