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.
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.
There are generally three types of Jedi classifications; Jedi Consular, Jedi Guardian, and Jedi Sentinel.
As for the weirdest Jedi ever, one candidate that's seemingly unchallenged would be the Celegian Jedi Master, Ooroo. He existed thousands of years before the film continuity and it's probably best that not many of his species be admitted into the Jedi Order.
Gray Jedi are those who, though having completed the teachings of the Jedi, operate independently and outside of the Jedi Council. They are typically seen as misguided, though they have not necessarily succumbed to the dark side.
Ki-Adi-Mundi was a prominent Jedi on the high council. Taken to the temple at the age of 4, he was an apprentice to Master Jedi Yoda. Though his blade was green when he was training (and in the film version), the crystals took on a purple hue shortly before rising to the council's ranks.
In the first-season finale, Moff Gideon, former officer of the Empire, emerges from the wreckage of his fallen TIE fighter. And he wields the Darksaber...
Plo Koon. Wise and compassionate, Plo Koon was one of the most effective Jedi masters, genuinely caring about the clones he commanded.
#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.
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.
Jedi are only loyal to the Jedi Order and have no time for things like marriage or family. The Jedi Code strictly forbids getting married, much to Anakin Skywalker's dismay.
While he is not Force-sensitive, Grievous has been trained in all forms of lightsaber combat by Count Dooku. Each of his mechanical arms can separate in half, allowing him to wield four lightsabers at once to overwhelm his enemies.
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%.
In Star Wars Legends and Canon, Galen Marek (Starkiller) is the only Jedi (other than Obi-Wan Kenobi) to put a beat down on Darth Vader/Anakin Skywalker.
Jedi Sentinel
Unlike the Scout, the Sentinel has the highest amount of Skill points per level of any Jedi class, making them even more versatile. Obi-Wan Kenobi's master Qui-Gon Jinn is probably the Star Wars character that best represents this blend of Force use and combat talent.
The first Dark Jedi was believed to be Xendor, who was the first member of the Jedi Order to fall. Other forerunners included Ajunta Pall and others who, after the Hundred-Year Darkness, were exiled from Galactic Republic space and became the ancient progenitors of the Sith Lords.

Biography. Legend had it that Yoda—a Jedi who became Grand Master—was trained by N'Kata Del Gormo.
Obi-Wan Kenobi
Brave, fearless, and above all, loyal - Obi-Wan is easily one of the most loyal characters in all of Star Wars, let alone just the prequel films. He's loyal to the Republic, loyal to the Jedi, and a loyal friend to all, especially Anakin.
Darth Sidious was also one of the greatest and most skilled Sith swordmasters, as he has mastered all the seven lightsaber forms, all their stances and techniques and is capable of using each form equally effective ambidextrously.
The Sith apprentice Darth Maul wielded a double-bladed lightsaber made by joining two hilts together end-to-end. Maul's dexterity and extensive training allowed him to use his weapon as a single-bladed saber, or to activate both crimson blades and fight multiple opponents at once.
As a Padawan, Ahsoka Tano used a green-bladed lightsaber, often wielding it in a non-standard reverse grip. Under the tutelage of Anakin Skywalker, Ahsoka became a skilled duelist, and built a second green-bladed lightsaber with a shorter, shoto-style blade.
However, neither Lucas nor Disney have recognized Gray Jedi as an official term or featured such characters in their stories. Here is why, despite their popularity in the Star Wars fanbase, Gray Jedi have never been canon.
