1 Yoda and Luke Arguably the most inspiring, lovable, and endearing master and apprentice duo that Star Wars gave its fans, Yoda and Luke started off as two arguing strangers on a filthy, desolate planet, and ended up saving the galaxy from one of the greatest threats it has ever faced.
Yoda considered Dooku the Order's greatest student for many reasons and Yoda himself believed Dooku would become the greatest of the Jedi.
Yoda was later trained by Huyang as his second Jedi Master during his time as a Padawan. Huyang was a professor droid who had passed along his wisdom to countless Padawans over the extent of thousands of years.
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.
According to Star Wars: Absolutely Everything You Need To Know, Yoda trained approximately 20,000 Jedi after reaching the rank of Master. Although it's a very impressive number, it's important to keep in mind that Yoda lived for 900 years, and became Master around the age of 100.
At some point, Yoda took on a human named Kantam Sy as his Padawan. The two were stationed at the Jedi Temple on the planet Endovar.
At one time, Dooku was the Padawan of Yoda, the Grand Master of the Jedi Order. In 86 BBY, Dooku later completed his Initiate Trials and hoped to be selected as the Padawan apprentice to Lene Kostana due to her mission in hunting down relics associated with the dark side.
Neither lightsabers nor the Force could help Yoda defeat Darth Sidious. Though Yoda was able to keep his adversary on his toes, he was unable to end the conflict, and their duel ended with no clear victor.
In his first appearance in the original trilogy, Yoda is described as the mentor of Obi-Wan Kenobi, and lives in exile on the swamp planet of Dagobah. He trains Luke Skywalker in the ways of the Force until his death at the age of 900 in Return of the Jedi, though he later returns as a Force spirit.
The count bested both Jedi in their duel, using the power of the dark side and taking advantage of young Skywalker's impetuous nature. But before he could land a killing blow, Master Yoda entered the fray. Not even Dooku's Sith-enhanced powers were enough for him to defeat Yoda.
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.
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.
Jedi training was the action of teaching an apprentice the ways of the Force in the Jedi Order. Under the Galactic Republic, Force-sensitive beings were brought to the Jedi Temple on Coruscant from across the galaxy and trained as Jedi younglings by Grand Master Yoda.
Master Yoda has risen above all others to claim the top spot as the most powerful Jedi of all time and the true chosen one according to IGN's audience. He won pretty handily as well, as he was victorious in 89,756 of his 95,243 battles and had a win percentage of 94.2%.
He began training under Master Yoda as a youngling until Qui-Gon Jinn chose him as an apprentice when he was 13 years old. By the time Obi-Wan was 17, their clashing personalities made for a rocky relationship -- but their bond evolved into a true partnership after a harrowing mission on Pijal.
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.
1 Darth Sidious
There has been no Sith, as powerful, meticulous, nor as evil as the Emperor himself, Darth Sidious. As previously mentioned, Sidious trained in the Dark Side by Darth Plagueis before Sidious killed Plagueis in his sleep, making Sidious a Sith Master.
Jaina was recognized as one of the most powerful force users in the expanded universe. She was given the title 'The Sword of the Jedi' and was believed to be an avatar of a trickster goddess, Yun-Harla. Though she was tempted by the Dark Side, she successfully emerged as a devotee of the Light.
According to the Darth Vader comics, after Order 66 all of the lightsabers of the fallen Jedi were collected and then put into a furnace to be destroyed. The comic specifically shows Yoda's lightsaber, presumably picked up from the floor of the Senate, in the hands of Mas Amedda to be thrown into the furnace.
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.
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.
