History. Practitioners of Form IV included
Qui-Gon Jinn was known for using Ataru, the same form that Yoda used. This form was known for the intense acrobatics that were involved, with this one having the most complex maneuvers out of all of the forms.
Form 4 is for corporations only.
A graceful combat style, it became a specialist form for duels with Sith opponents. 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.
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.
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 Masters Vrook Lamar, Zez-Kai Ell, and Kavar were all skilled in its use and were able to pass on their experience to others. Jedi Master Atris, who fell to the dark side during the First Jedi Purge, was also known to employ the form.
Throughout his career as a Jedi knight, Obi-Wan used Form III Soresu in lightsaber combat, which was originally created as a counter to the dueling intricacies of Form II's fencing style and focused on minimizing movements while optimizing defense. Obi-Wan wasn't just proficient at this technique, though.
Form VII: Vaapad
The key architect of Vaapad was Jedi Master Mace Windu, who developed the form to address his weakness by controlling his inner darkness and channeling it into worthy ends.
Form VI, also known as Niman, was the sixth form of lightsaber combat used by members of the Jedi Order.
Through the Force, Yoda was considered to have mastered Form IV to its highest level. He used it in almost all of his battles, and his mastery of the style caused others to describe him as virtually unstoppable against most opponents, including Separatist battle droids, despite his small size and advanced age.
Obi-Wan Kenobi was highly skilled in Form III. Over the course of the Clone Wars, Kenobi continued to develop his skills.
Kit Fisto, a master of Form I. A master practitioner of Shii-Cho, Kit Fisto was considered to be one of the best swordsmen in the Jedi Order. His mastery of the form was advanced, and he applied it in many battles and duels, always with his trademark smile.
At first, Rey primarily fights with a lightsaber the same way she would have with her quarterstaff. However, after studying Luke's Jedi scripture and training with Leia, Rey probably uses Form VI: Niman, a jack-of-all-trades lightsaber form that combines different aspects of Forms I through V.
Obi-Wan Kenobi adopts a Form I stance. Form I was the most ancient lightsaber form still in use at the time of the Jedi's fall. In fact, it was the first form created, codifying standard lightsaber techniques in the early centuries of the Jedi Order.
Kendosu, or the Way of the Varactyl, was a form of swordplay created by Jedi Knight Scott Borek in 14 BBY. Based on Republic records and personal account, the Form was conceived in 21 BBY to give the Jedi an advantage in combat against the Sith during the Great Galactic War.
Sokan was a form of lightsaber combat. Developed by the ancient Jedi Knights during the Great Sith War, Sokan combined tactics that allowed for evasion and mobility with the kinetic motions of Form V combat.
Form VI, also known as Niman, the Way of the Rancor, the Moderation Form, and the diplomat's form, was the sixth form of the seven forms of lightsaber combat. This fighting style was a hybrid martial art created by effectively combining elements of the preceding lightsaber forms into a single, generalized form.
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.
The Forbidden Forms were forms of lightsaber combat used by the Sith during the Sith Wars. According to the testimonies of the Jedi Cervil the Uncanny, lightwhips—a lightsaber variant with a flexible blade—were used to defend against Sith Lords who utilized the forms.
Form IV, also known as Ataru (pronounced uh-TAR-oo) or The Aggression Form, was the fourth form of lightsaber combat invented by the Jedi Order. An acrobatic combat style, Ataru could be used to defend against incoming projectiles but was best suited for open spaces and attacking.
For Ahsoka, lightsaber form is crucial because she's a dual wielder. While Jar'Kai is the method of dual wielding, Ahsoka Tano's lightsaber form is a variant of Form V, much like her master, Anakin Skywalker.
Form V: Djem So
As stated in numerous sources, Luke takes after his father with his preferred form of lightsaber combat being Djem So. This is reflected in his fighting style, which mostly consists of a well rounded mix of powerful two-handed strikes and precise counter attacks backed up by a solid defence.
