Yoda. Yoda was a wise, experienced, and powerful Grand Master of the Jedi of an unknown species and the oldest known prophet in existence (having lived at least 900 years), considered the wisest and most powerful Jedi Master within the Star Wars universe.
As soon as the force sensitive children are brought to the jedi temple they become younglings and then become padwans at the age of 8 or 9 and depending on their skill they could be a jedi knight by 18 years old but that's very rare most become knights in their mid 20s and can be as late as 29.
In the Star Wars Legends continuity, the founders of the Jedi Order were Jedi Masters Cala Brin, Garon Jard, Rajivari, and Ters Sendon.
#1 – Yoda. Yoda is widely considered to be the greatest Jedi of all time, and with good reason. He is a master of the Force, a skilled warrior, and has an unmatched wisdom that comes from centuries of experience. He is the embodiment of what it means to be a Jedi, and his legacy lives on long after his death.
Held by several Masters throughout the Order's history, the earliest recorded Grand Master was Biel Ductavis, who was appointed in 10,966 BBY.
The clear answer for the smartest Jedi of them all is Master Yoda. This mysterious but beloved character comes from a species about which very little is known, and has survived through many eras, stretching back to the High Republic.
Jedi Master Yoda is the most powerful of them all. This should come as no surprise, as he was the head of the Jedi Order in the prequels and was revered for his abilities during the original trilogy. Yoda's power is unmatched and was a real threat to Darth Vader and the Imperials.
When it came to assembling a list of the greatest Jedi in Star Wars, no character was as quick to mind as Obi-Wan Kenobi. Both Yoda and Qui-Gon Jinn trained Obi-Wan Kenobi. The training of these two proved to be fruitful for Kenobi as he was the first Jedi in 1000 years to defeat a Sith Lord in battle.
Luke Skywalker is the most famous and important Jedi Knight in the entire Star Wars movie series and, arguably, the entire franchise itself.
Coleman Trebor
He was the Jedi that looked more or less like a bipedal dinosaur with opposable thumbs. Coleman Trebor is by far the weakest Jedi to ever exist. He made his movie appearance in Attack Of The Clones.
Obi-Wan Kenobi
Through it all, Obi-Wan reveals himself to be one of the very best examples of what a Jedi Knight should be: selfless, kind, and willing to do whatever it takes to protect those in need.
According to Star Wars Legends content, the first Sith was a former Jedi Master, Ajunta Pall, who became a so-called Dark Jedi, or “Fallen” Jedi. As the name implies, these Force-sensitives chose to practice the Dark Side, and rejected the Light Side of the Force.
Yoda. Yoda was a wise, experienced, and powerful Grand Master of the Jedi of an unknown species and the oldest known prophet in existence (having lived at least 900 years), considered the wisest and most powerful Jedi Master within the Star Wars universe.
Vernestra, Mirialan, was Padawan to Stellan Gios. She works hard and is devoted to the Jedi Order, more so than most others her age. At sixteen she is one of the youngest Knights in a generation. She struggles to fit in with the adults while also setting a good example for the younger Jedi.
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.
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.
But one Jedi stands above the rest and needs to start getting recognized as the greatest Jedi who ever lived. That is none other than Obi-Wan Kenobi. While this saga is ultimately the story of the Skywalkers, Obi-Wan is arguably the best and most pure Jedi to ever come out of it.
Arguably, some of the rarest types of Jedi were the so-called Iron Knights. These are members of the Shards species - crystals with a brain of their own. They were Force-sensitive and all trained under the tutelage of Jedi Master Aqinos. The Shards had droid bodies, similar to that of General Grievous.
1. Darth Sidious (Star Wars: Episode I – The Phantom Menace) Truly, the most powerful Sith Lord was Darth Sidious, better known in his public persona of Chancellor (later Emperor) Palpatine. Through cunning and manipulation, Sidious killed his master to claim the mantle of Dark Lord of the Sith.
1 Darth Vader - Hundreds
During his time as Darth Vader, the powerful Force-user continued to hunt down Jedi, devoting himself to the Order's extinction until he became aware of his son's existence.
Ahsoka Tano, the former Jedi Padawan who aided in the rebellion against the Galactic Empire, is acknowledged as the sole possessor of the white lightsaber.
The second time Yoda mentions his long life is in Return of the Jedi, when he tells Luke, “When you reach 900 years old, you will not look as good as you will.” If we take Yoda at his word, that means the Jedi Master died at the ripe old age of 900.
