Most Powerful Sith Lords of All Time
The Sith are dedicated to the "Sith Code" and to mastering the Dark Side of the Force. Sith Lords traditionally use the title Darth-prefix before their Sith name. The Sith's Dark Side methodology, which draws on the Force through severe negative emotions, is antipodal to that of their archenemies, the Jedi, who rely on the Force's "Light Side," i.e., the Force as experienced through disciplined states of quietude and compassion. Notably, both the Jedi and Sith shun romantic and familial love, as the Jedi fear such love will lead to attachment, and thus selfishness, and the Sith fear it will compromise their connection to the Dark Side of the Force. Although the Sith are intimately linked to the Dark Side, not every "Dark Side"-user is a Sith; nor is every "Light Side"-user a Jedi.
Darth Vader, also known by his birth name Anakin Skywalker, is a fictional character in the Star Wars franchise. Vader appears in the original film trilogy as a pivotal antagonist whose actions drive the plot, while his past as Anakin Skywalker and the story of his corruption are central to the narrative of the prequel trilogy. The character was created by George Lucas and has been portrayed by numerous actors. His appearances span the first six Star Wars films, as well as Rogue One, and his character is heavily referenced in Star Wars: The Force Awakens. He is also an important character in the Star Wars expanded universe of television series, video games, novels, literature and comic books. Originally a Jedi prophesied to bring balance to the Force, he falls to the dark side of the Force and serves the evil Galactic Empire at the right hand of his Sith master, Emperor Palpatine (also known as Darth Sidious). He is also the father of Luke Skywalker and Princess Leia Organa, secret husband of Padmé Amidala and grandfather of Kylo Ren.
In Legends, Sidious acknowledged him as capable of killing him, and certainly a threat to him. Jedi believed that Sidious would be a fool not to fear him. Keep in mind that Sidious is constantly referred to in Legends as the most powerful Sith. Vader in Legends is on Palpatine's level In canon, he lost no potential on Mustafar, and his connection to the Dark Side actually strengthened. Sidious has complimented his abilities as unparalleled. Twice, he has recieved visions of him striking down the Emperor, and his visions to tend to have an element of truth to them. Vader isn't on Sidious' level here. Sidious is close to Vader's level
Revan is a fictional character in BioWare's Star Wars: Knights of the Old Republic video game. The character may be either male or female, though Revan is canonically male and follows the game's light-side path. The player's choice of a male or female Revan changes only which characters the player character can fall in love with (as well as slightly altering the way some characters act towards the player). He was voiced by Rino Romano in Knights of the Old Republic and Jeff Bennett in Star Wars: The Old Republic. Revan's story is further explored in Drew Karpyshyn's 2011 novella Star Wars: The Old Republic: Revan. The book details the events of Revan's life after the events of Star Wars: Knights of the Old Republic, in which Revan attempts to recover his lost memories from the period of the Mandalorian Wars and from his and Malak's travels to discover the Sith empire.
Darth Vitiate / Sith Emperor
Vitiate, known for the vast majority of his life as simply the Sith Emperor and known to his Eternal Empire as Valkorion, was a Dark Lord of the Sith who reconstituted the Sith Empire after its destruction in the Great Hyperspace War and went on to rule it for over 1300 years. To the people of the Eternal Empire over which he ruled in his later life, he was His Glorious Majesty, Slayer of Izax, Immortal Master and Protector of Zakuul—their Immortal Emperor. Born in 5113 BBY as Tenebrae, the illegitimate Sith son of Lord Dramath of Medriaas and a poor farm woman, the child who eventually became the Emperor killed his own father at the age of ten and was granted the title of Lord Vitiate by the then–Dark Lord Marka Ragnos three years later. Vitiate renamed his world Nathema and ruled it for the next century, content to exclude himself from Sith power struggles and even the Great Hyperspace War when the Galactic Republic destroyed the Empire in 5000 BBY. Summoning the remaining Sith Lords to Nathema with the promise of salvation from the Jedi, Vitiate turned on his fellows and used their strength to perform a ritual that made him immortal, at the expense of every living thing on Nathema.

Darth Nihilus (pronounced /ˈnaɪ.ə.lɨs/) 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. He survived the activation of the Mass Shadow Generator superweapon during the war's final battle at the planet of Malachor V, which surrounded the planet with a destructive spatial phenomenon known as a mass shadow. Experiencing the shadow that obliterated almost everything on and around the planet made Nihilus crave Force energy. The affliction painfully ravaged his body while rendering him a wound in the Force. He was found by a seeker of these, the Sith Lord Darth Traya, who told him that she could teach him to feed his endless hunger. He accepted her offer of apprenticeship at the Trayus Academy on Malachor V, where he, over time, became one of three concurrent Dark Lords of the Sith.

Kun was driven by incredible ambition to become a great Jedi and frequently dueled with his fellow students to hone his skills. This led to him deciding to study Sith history and knowledge on his own. It was through these studies that Kun learned of Freedon Nadd, a Jedi turned Sith Lord. However, his master caught him with the holocron containing this knowledge and reprimanded him. Baas eventually had Kun face Crado and Sylvar in lightsaber duels and he easily defeated the former.
