Dooku became a Jedi Knight in his early twenties and took Qui-Gon Jinn as his first Padawan. The two were quite close in age, with only ten years separating them. When only ten, Jinn had impressed Dooku with his potential.
Dooku was the Jedi Master of Qui-Gon Jinn, who eventually achieved the same rank in the Jedi Order. In 68 BBY, Dooku having finished training Averross by this point, would take a 12-year-old Qui-Gon Jinn as his second Padawan.
During one mission, Dooku sees visions of many different futures through the Force, which shake him to the core. Eventually, Dooku becomes a Jedi Knight, trains two Padawans to knighthood, and joins the Jedi Council, hoping to bring about real change in the Republic.
The first Padawan to Jedi Knight Qui-Gon Jinn, Feemor was successfully trained to Knighthood by Jinn, who was in turn granted the title of Jedi Master. Jinn later took a young boy named Xanatos as his second student, but the latter turned against his Master.
Bottom line, Dooku never considered himself a Sith. And he wasn't; he was a man looking to change the galaxy in a way the Jedi were unwilling to try. And that is why he joined the Sith and became Darth Sidious' apprentice, Darth Tyrannus. When Dooku became Sidious's apprentice, he was already an elderly man.
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.
His former colleagues in the Jedi Order saw Dooku as misguided but a man of principles, and refused to believe he could be an advocate of violence and war. They were wrong; Dooku had sworn allegiance to the Sith Lord Darth Sidious, taking the name Darth Tyranus.
Though he saw Anakin's potential, Yoda could not ignore the danger inherent in Anakin's unrestrained emotional attachments. To teach Anakin responsibility, Yoda assigned Skywalker a Padawan learner: Ahsoka Tano. Yoda knew there would come a time when Anakin had to let go of Ahsoka.
In 0 BBY, during the Galactic Civil War and more than a decade before Rey's birth, her voice was heard by Padawan Ezra Bridger during his brief visit to the World Between Worlds—a place that existed beyond time and space.
She eventually became the Padawan of a human male Jedi Master, Stellan Gios. Vernestra was enough of a prodigy that she eventually attained the rank of Jedi Knight at the age of only fifteen, making her the youngest Knight in a generation.
Billaba became Windu's Padawan and trained under the Jedi Master in the ways of the Force. During her training, Windu allowed her to study Form VII variant known as Vaapad. She eventually became a Jedi Knight, renowned for her skills with a lightsaber and favored Form III when teaching other Jedi.
Mission to Mathas. Padawan Windu was trained in the ways of the Force by Jedi Master Cyslin Myr. Following his early trials as a youngling, Windu attained the status of Padawan by becoming Jedi Master Cyslin Myr's apprentice.
Eventually, Qui-Gon completed his training, became a Jedi Master, and took on a Padawan of his own: the steadfast Obi-Wan Kenobi.
Jedi Master Mace Windu and Count Dooku were the faces of Star Wars' Clone Wars on their respective sides of the conflict because both were second in command to very powerful masters. Because of their control of the Force and individual skill with a lightsaber, a duel between them would have been a battle for the ages.
At some point, Yoda took on a human named Kantam Sy as his Padawan.
A Sith Lord with the ability to prevent death and create life, Plagueis is the mentor of Sheev Palpatine/Darth Sidious, who, in accordance to the Sith's Rule of Two, eventually betrays Plagueis by murdering him in his sleep, taking his place as Sith Master.

Boba Fett was definitely dead. We all saw it: a partially blinded Han Solo unknowingly whacked him with a stick in Return of the Jedi, his jetpack malfunctioned, and then he fell into the mouth of a massive sand monster.
Dooku belonged to the aristocracy, and his weapon reflected an older, more chivalric style than the Jedi he faced. It also reflected his status as the head of the Separatists: the lightsaber looked far more ceremonial than practical, suggesting that he himself did not face combat nearly as much as the Jedi did.
In his final bout, Dooku lost his Sith lightsaber to the Jedi Knight Anakin Skywalker once he was defeated in a duel aboard the starship Invisible Hand. Skywalker used Dooku's own weapon to behead the Sith Lord and end his life.
A deadly, agile Sith Lord trained by the evil Darth Sidious, Darth Maul was a formidable warrior and scheming mastermind. He wielded an intimidating double-bladed lightsaber and fought with a menacing ferocity.
