Shortly after the Battle of Naboo, he became dissatisfied with the Jedi Order and fell to the dark side of the Force, becoming the Dark Lord of the Sith Darth Tyranus. After leaving the Jedi Order, he served as Count of Serenno and Head of State of the Confederacy of Independent Systems during the Clone Wars.
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.
Dark Jedi was a term for a Force-sensitive individual who followed the dark side of the Force but wasn't a Sith. This is quite similar to Dark Acolyte. The title of dark acolyte, also called Sith acolyte, held by Asajj Ventress and Savage Opress during their time under Count Dooku.
Grey Jedi also are in questioning, not existing (yet) in the new cannon. But, if we still consider the old Cannon or Legends, Dooku is more like Grey Jedi. He is not evil, actually he tries just to improve his own knowledge and to infiltrate the Sith from inside.
He was: Darth Tyrannus. His persona as Count Dooku was better suited to his role as leader of the Separatist faction. If he revealed himself as a Sith publicly, rather than just a former Jedi who left the order because of its supposed corruption, that would have damaged his credibility to most of the Separatists.
Why The Sith HATE Dark Jedi So Intensely - Star Wars Explained
Why didn't Dooku use his Sith name?
Sidious may have given Dooku the title of Darth Tyranus, but because the Jedi Order knew him as Count Dooku, greatly preferring to not indulge his role as a Sith, they continued to call him by that name.
He was not a Sith in the same way that Darth Sidious or Darth Vader were but actually wanted to save the galaxy. Yet, like all authoritarians who think they should be in control of who lives or dies, Count Dooku's decisions were the wrong ones and led to his undoing.
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.
The term “gray Jedi” in Star Wars is somewhat of a misnomer, considering that the definition refers to one who is practically non-Jedi. That being said, quite a few Jedi can be placed into this category. But Mace Windu identified as a Jedi despite his possible inclusion in the "gray" category.
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. Instead, he was just a chaotic mess of the dark side (until he eventually found his way back to the light).
Deeply spiritual, Chirrut Îmwe believes all living things are connected through the Force. His sightless eyes do not prevent him from being a highly skilled warrior.
In any case, other than Mace Windu (Jackson), the following Jedi characters were portrayed by black actors: Adi Gallia, played by British model/actress Gin Clarke: Would Anakin have turned to the Dark Side if a Jedi other than Mace Windu had been fighting Sidious?
In his story, Maul poses as a member of a criminal cartel to kill a Force-sensitive thief for Darth Sidious, and experiences a vision of an alternate life as a peace-keeping Jedi, which he denies, much to Sidious' content. The story takes place shortly before The Phantom Menace.
While Dooku may be powerful enough to hide his Sith eyes, there is another reason for his unusual appearance. Dooku's eyes were never yellow because he did not have the same motivation and emotions as other Sith. Dooku was an idealist who left the Jedi because he thought they had lost their way.
Who Do Fans Consider Gray Jedi? Aside from Qui-Gon Jinn and Ahsoka Tano, other characters have been dubbed Gray Jedi by fans, even though the term isn't canon. For instance, Kylo Ren — a.k.a. Ben Solo — is a Force-user who taps into both the Dark and Light sides of the Force.
Characters like Cade Skywalker, Asajj Ventress, Quinlan Vos, Kreia, Revan, Kanan Jarrus, Ezra Bridger, and Ahsoka Tano all demonstrate different aspects of being Gray Jedi.
Around 44 BBY, Jedi Master Qui-Gon Jinn was thought of as a Gray Jedi by some members of the Order for his frequent opposition to their demands. One group of renegade Jedi described themselves as "gray" even though they held the same views as the Jedi Council on the subject of the dark side.
I suggest that when Ren's emotional outbursts, impulsivity, and unstable self-concept are looked at more closely, there is plenty of evidence to suggest that he suffers from Borderline Personality Disorder and that perhaps he is simply not just a cold-hearted villain after all.
The hilt of Ren's lightsaber also featured a black burned appearance as a result of its first activation without the vents to compensate for the unstable power of a damaged kyber crystal. Compared to typical lightsabers, this weapon had an unusual sound frequency where the ignition hiss sounded crackles and sputters.
Some believe this is part of the evidence for the Force Mask theory. Although, it's probably because all Sith's eyes turn yellow through the Dark Side of the Force, in which Palpatine released when using Force Lightning. He WAS a former Jedi.
Summary. Jar Jar Binks's clumsiness may not be genuine, but rather an act to disguise his true nature as a Sith Lord infiltrating the Republic. Palpatine carefully orchestrated events to manipulate the galaxy, and Jar Jar's involvement suggests he may have been the eyes and ears on Naboo.
The most agreed upon theory, started by Reddit user Lumparoo in 2016, is that Jar-Jar is a powerful Force-user conspiring with Darth Sidious. In addition to this, some believe he either trained, or was supposed to become Supreme Leader Snoke, or that he is a reincarnation of Darth Plagueis.
When Qui-Gon passed the Jedi Trials and became a Jedi Knight, Dooku told him not to trust others because his need to reach out to others left him vulnerable to betrayal. 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.
