Chastened by his former Master on the principle of the Rule of Two, Maul abandoned his claim to the mantle of the Sith, focusing instead on building an empire of his own—the Crimson Dawn—by controlling the criminal underworld.
Yes. Lord Maul was trained by Darth Sidious to be his true apprentice. Remember that Sidious did not know about Anakin Skywalker previous to the Naboo invasion events. Maul was to be the pinnacle of Sidious' training and the triumph of the Sith's return to the light.
Serving as a defining moment on the same level as Luke Skywalker's vision in the caves of Dagobah, Darth Maul's surreal time as a Jedi would serve to cement his beliefs that the Jedi Order had to be exterminated at all costs.
However, joining the Sith means declaring loyalty to the dark side, which Anakin did before his eyes turned yellow. This may explain why Kylo Ren, torn between the light and dark, didn't have yellow eyes in the Star Wars sequel trilogy, as killing his father split his spirit even more.
History. 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.
Though seemingly killed by Obi-Wan Kenobi at the end of the film, Darth Maul returned in the 2008 animated series Star Wars: The Clone Wars (voiced by Sam Witwer).
Despite following the dark path, he wanted to make it clear he was no longer part of the Sith Order. Prior to this, he was a Zabrak Sith assassin hailing from the planet Dathomir and served as the apprentice Dark Lord of the Sith Darth Maul, but was considered expendable by Darth Sidious.
Legend had it that Yoda—a Jedi who became Grand Master—was trained by N'Kata Del Gormo. A Force-sensitive Hysalrian, N'Kata Del Gormo was trained in the ways of the Force and achieved the rank of Master within the Jedi Order.
Regardless, based on the season 7 of The Clone Wars, and the fact that Darth Maul was aware of Anakin Skywalker's future and his role as the Chosen One, it is very likely that Darth Maul indeed feared Darth Vader to some extent, and preferred to avoid a direct confrontation with him, at least, on his own.
Count Dooku was a menacing Sith Lord and central figure in the Clone Wars. Once a Jedi -- trained by Yoda -- he became disillusioned with the Jedi Order and thirsted for greater power.
While Luke Skywalker finds a way to escape the crushing influence of the dark side and redeem himself as a Jedi Knight, that doesn't detract from the fact that he was a full-blown Sith for a time, just like his father before him.
During the battle, Anakin, who had been known as the Sith Lord Darth Vader, was redeemed by Luke and brought balance to the Force. However, the redemption cost Anakin his life, having been mortally wounded by the Emperor, Darth Sidious, while killing his former Master.
Anakin Skywalker's birth mystery is solved - his mother, Shmi Skywalker, reveals that there was no father and she can't explain what happened. Qui-Gon Jinn believed that the Force itself created Anakin in Shmi's womb, making him the Chosen One who would bring balance to the Force.
As the son of Mother Talzin, the Zabrak male was taken from a young age by Sidious to act as his impressionable apprentice. The boy was raised as Darth Maul, a name he carried throughout his life. In Legends, it was insinuated that he was born "Maul" before attaining the honor of the "Darth" title.
When Qui-Gon was killed by Darth Maul, Dooku was so saddened that Qui-Gon's death lead to Dooku's transformation into the Sith Lord Darth Tyranus. He would later provoke the memory against Obi-Wan Kenobi, Jinn's apprentice.
Thus, while Qui-Gon was less powerful than the likes of Yoda and Mace Windu, Palpatine feared him more. In the simplest terms, he was a wild card, and with the Sidious executing an intricate decades-long plan to seize power and destroy the Jedi, a wild card was something he just couldn't afford.
Rey Skywalker, known only as Rey throughout the First Order-Resistance War, was a human female Jedi Master who fought on the side of the Resistance during the war. A former scavenger from the planet Jakku, her life was changed by the tumultuous events of the last days of the New Republic Era.
As a Sith, Praven was very strong in the dark side of the Force, though he felt stronger with the light side as a Jedi. He wielded a single red-bladed lightsaber as both a Sith and a Jedi, and he was skilled in the use of a wide variety of Force powers, including Force lightning, Force blasts, and Force paralysis.
The upcoming Obi-Wan Kenobi series may feature the grand return of Hayden Christensen's Darth Vader, but he's far from the only villain headlining the latest live-action Star Wars project. Obi-Wan is also butting heads with the Sith Inquisitorius, Vader's elite, Jedi-hunting assassins.
