With that said, Christopher Lee's prolific Dracula performances in movies was most certainly inspiration for giving his Star Wars character, Dooku, a backstory that included him descending from a Count and Countess, therefore making him a Count of the planet Serenno.
Because Dooku is his original family name (i.e. not his Sith name) and he was of noble blood (a Count from whatever his home planet was). His Sith name, granted by Darth Sidious, was Darth Tyrannus, but it was a *secret* — just as Darth Sidious himself was known to the galaxy as Sheev Palpatine.
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.
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.
[NEW Footage] Dooku VS Yoda was almost 10X CRAZIER
Did Dooku know Palpatine was a Sith?
Indeed he did. Dooku (aka Darth Tyrannus) knew his master's identity. At this point the Jedi thought Dooku was the Sith Master. The kidnapping was planned to reinforce public support for Palpatine while further confusing the Jedi about his true identity.
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.
Kostanza Dooku was a female Human from the planet Serenno. She belonged to one of the Great Houses, the six wealthiest noble families on her homeworld. She married the Count of House Dooku, brother to the famed Jedi Master Dooku. When her husband died, Kostanza Dooku served as regent over their House.
Once a Jedi -- trained by Yoda -- he became disillusioned with the Jedi Order and thirsted for greater power. Dooku voluntarily left the light side behind and became Darth Sidious' dark side disciple, taking the secret name Darth Tyranus and leading the Separatist army.
Studying Jedi Archive records, Dooku based his new weapon design after the curved hilts that were standard during the heyday of Form II lightsaber combat. The curve allowed the hilt to fit better into his hand, allowing for superior finesse and precise blade control.
Like all in the Order, the young Korun boy was taught by Grand Master Yoda when he was a learner, and eventually went on to become a Padawan to another Jedi. At one point during his apprenticeship, Windu trained under Master T'ra Saa.
Count Dooku's real name, Dooku, was more fitting than his Sith title, Darth Tyranus, as it speaks to his manipulative nature. Dooku played a crucial role in weakening the Jedi and the Republic from within, planting doubt and eroding trust.
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.
Katri was a Mirialan Jedi Master and member of the Jedi Order's Jedi High Council. Between 68 BBY and 42 BBY, she was killed by a group of security guards on Raxus Secundus, and her death was investigated by Jedi Masters Mace Windu and Dooku. Her seat on the Jedi Council was awarded to Windu.
With a potential Jedi Code-defying love affair with another Jedi, Dooku is more of a foil to his Clone Wars-era enemies, Anakin Skywalker and Obi-Wan Kenobi, with Dooku's lover, Jedi Master Jocasta Nu, possibly retaining feelings for Dooku well after he joined the ranks of the Lost Twenty.
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).
Summary. 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.
Maul actually was his Sith name. In the Rebels tv series, Maul says to another character that he once had a real name, but he has long since forgotten it. Palpatine took Maul from his mother and gave him his Sith name as an infant. His real name is lost to time.
Sidious revealed to Maul that he did not intend to kill his former apprentice, as he still had use for Maul; it was Sidious' hope that Maul would lead the Sith to Mother Talzin, Maul's mother and the leader of the Nightsisters, so she could be eliminated as a potential threat to the eventual Sith rule of the galaxy.
