Ataru was characterized by Force-assisted acrobatics, such as somersaults and leaping strikes, both for attack and defense. Another characteristic of the form was its fast strikes from multiple directions. Notable users of this combat form during the Old Republic included Yoda and Qui-Gon Jinn.
Qui-Gon Jinn was an Ataru master. The fourth lightsaber form, Ataru, originated some centuries after Form III. In many ways the inverse of Soresu, Form IV focused almost exclusively on offense. Its practitioners sought to end a fight as quickly as possible rather than outlast the foe.
Form II relied on careful and controlled strikes instead of power and strength. Count Dooku was a master of this form and trained the Sith assassin Asajj Ventress in its use, though hers was less elegant than her master's. The Grand Inquisitor was a proficient Form II practitioner.
Qui-Gon Jinn's simple yet elegant lightsaber served him in many conflicts. The maverick Jedi designed his green-bladed saber to imitate the weapon of his master, Count Dooku; Qui-Gon's saber, in turn, inspired the design of Obi-Wan Kenobi's first Jedi weapon.
Practitioners of Form V included Jedi Masters Aayla Secura, Adi Gallia, Plo Koon and Luke Skywalker, Jedi Knights Anakin Skywalker and Ulic Qel-Droma, and Dark Lord of the Sith Darth Bane.
Jedi Battlemaster Cin Drallig and Grand Master Yoda had knowledge and mastery of all seven forms, including Juyo, befitting Drallig's role as lightsaber combat instructor at the Jedi Temple and Yoda's reputation of having mastered all forms of lightsaber combat as did Anoon Bondara, another lightsaber instructor.
7. Famous Practitioners of Form VII: Juyo/Vaapad. Some of the most famous practitioners of Form VII: Juyo/Vaapad include Mace Windu, Darth Vader, and Darth Sidious. Each of these characters had their own unique style and technique when using the form.
In material that is now considered Legends, Qui-Gon is even described as a Gray Jedi. Additionally, the term has also been applied to Force-sensitives who aren't affiliated with the Light or Dark side of the Force. Quite literally, these Gray Jedi don't see things in black and white, or light versus dark.
The late Master's legacy suggests that he may have actually been a Sith working against the Jedi Order all along, successfully orchestrating the downfall of the Jedi and the rise of the Empire.
Becoming the mentor to Obi-Wan Kenobi, Qui-Gon Jinn sought to teach him the best he could. Jinn became a Jedi Master in his own right, a master who developed an independent attitude towards the Jedi Order. Others saw him as a maverick Jedi, one who would disobey the Jedi Code if he felt it was the right decision.
Kylo Ren's lightsaber form was something of a hybrid, which blended three styles together: Djem So, Juyo, and Niman. Djem So used an irregular reverse grip and was meant for practitioners who loved fighting with a more offensive edge - a perfect fit for Ren.
Jarrus later used Form III against the Grand Inquisitor, who recognized it as a staple of Billaba's instruction and was able to counter Jarrus' attempts to use it against him. Obi-Wan Kenobi also mastered the Soresu form of combat.
Practitioners. Kavar, Vrook Lamar, and Zez-Kai Ell, all Form VI instructors. Ironically for a fighting form designed to encourage moderation over aggression, Niman was the chosen discipline of the fallen Jedi-turned-Sith Lord Exar Kun.
In conclusion, Form VII, also known as Juyo or Vaapad, is undeniably the most aggressive lightsaber style in the galaxy. Jedi Master Mace Windu's mastery of this form exemplifies its power and its dangers.
Darth Sidious, was in the earliest stages of his plan to take over the galaxy, and he was afraid a certain Jedi might get in his way. Interestingly, however, that Jedi wasn't Yoda or Master Windu, but instead Qui-Gon Jinn.
Even though Palpatine was far more. powerful than Qui Gon, there was no Jedi he feared more, save maybe Yoda. This was largely due to the fact that Qui Gon was. unlike most Jedi of the time.
Qui-Gon actually did very well in his fight against Maul. Which is a testament to his skill and knowledge of the force because he was at a severe disadvantage. Maul had been trained specifically to kill him, while Qui-Gon had only really dueled other Jedi in friendly sparring matches.
The term “gray Jedi” in Star Wars is somewhat of a misnomer, considering that the definition refers to one who is practically non-Jedi. That being said, quite a few Jedi can be placed into this category. But Mace Windu identified as a Jedi despite his possible inclusion in the "gray" category.
Qui-Gon is shown to have a much deeper knowledge of the cosmic Force than every other Jedi. Qui-Gon Jinn was the first to become a Force ghost, even teaching Jedi Grand Master Yoda how to do the same in the last arc of the incomplete Star Wars: The Clone Wars season 6.
Darth Maul's lightsaber form is the aggressive Form VII: Juyo, also called the “Ferocity Form.” He also draws on Jar'Kai, the method of dual wielding or carrying a double-bladed lightsaber.
In canon, Mace Windu mastered all seven forms of lightsaber combat. Mace Windu was considered and called the champion of the Jedi. He was considered to be both a champion of the Jedi Order and one of the best lightsaber duelists ever produced.
Mace windu used variant of juyo named vapaad. This technigue allowed him to stalemate darth sidious in lightsaber duel. Which are the 7 lightsaber fighting styles and which Jedi uses each? Well, as you said, there are 7 forms of lightsaber combat.
