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.
Form V evolved into an accepted style by combining the defensive maneuvers of Form III with the more aggressive philosophy and tactics of Form II. Form V required a higher level of physical strength than the other lightsaber forms, due to its focus on complete domination of its practitioners' opponents.
Notable users of this combat form during the Old Republic included Yoda and Qui-Gon Jinn. The New Jedi Order preserved knowledge of Ataru, and Jedi Masters such as Luke Skywalker, Mara Jade Skywalker, and Kyle Katarn all employed it.
Anakin used the form 5, it's known a the Way of The Krayt Dragon. Form 5, also known by its two primary disciplines of Shien and Djem So, is the offensive version of form 3 and relies on strength.
Anakin Skywalker was a known user of Djem So, both during his initial stint as a Jedi and later when he subsequently fell to the Sith. The Shien variant of Form V allowed the utilization of an unconventional reverse grip, which Ahsoka Tano was known to prefer and use during battles.
Affiliation. Form VII, also known as Juyo, the Way of the Vornskr, or the Ferocity Form, was the seventh of seven forms recognized as canon for lightsaber combat by the last Jedi Council of the Old Jedi Order.
Obi-Wan Kenobi was highly skilled in Form III. Over the course of the Clone Wars, Kenobi continued to develop his skills.
Kylo Ren's Lightsaber Form
The evidence isn't entirely clear, but it is most likely that he was an adherent of Form V, particularly the Djem So variant. Ren's fierce fighting style has the hallmarks of Djem So, which demands a high degree of speed and strength to execute a flurry of attacks and counterattacks.
What are Yoda's Lightsaber Forms? Ataru, or Form IV, became Yoda's go-to. It's something he put on display during two duels in the Prequel Trilogy when confronting Count Dooku in Attack of the Clones and Darth Sidious in Revenge of the Sith. Of the seven dueling forms, Form IV is by far the most breathtaking.
Obi-Wan originally used Form IV commonly known as Ataru like his master, Qui-Gon Jinn. After Qui-Gon's death, Obi-Wan realized the flaws of Form IV and instead became a practitioner of Form III, Soresu, which is the most defensive of the seven lightsaber forms.
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.
Grand Master Yoda and Swordmaster Mace Windu were also proficient in its usage, as they were said to have fully mastered all the seven forms of lightsaber combat. Master Kirlocca of the Almas Academy was also credited as having mastered Form I.
Form VI, also known as Niman, was the sixth form of lightsaber combat used by members of the Jedi Order. It could be used to combine double-bladed lightsaber combat with other Force abilities, like pushes and lifts.
A notable Jedi adherent was Johun Othone, who took full advantage of Form VI's inherent versatility during the pitched battles of the war.
Affiliation. Form VII, known by its two primary disciplines of Juyo and Vaapad; and also known as The Ferocity Form, was the seventh form of lightsaber combat. It was considered the most aggressive and unpredictable form.
Form V was the style of choice for Anakin Skywalker, who continued to use the form after becoming the Sith Lord Darth Vader. Luke Skywalker became one of the galaxy's most skilled practitioners of Form V, as shown in Return of the Jedi and various Legends-era non-movie material.
Other Jedi practitioners of Makashi included Dooku's former Padawan Qui-Gon Jinn; famed Jedi Battlemaster Cin Drallig; Jedi Council Master Shaak Ti; and Master Jerec, who was said to have mastered the form. Grand Master Yoda appeared to have also used the form, as he had once taught Dooku the Makashi salute.
The lightsaber's redesign was a byproduct of the bleeding process that damaged its kyber crystal, rendering it dangerously flawed and unstable, and necessitating the lateral vents were meant to prevent the cracked kyber crystal from overloading.
Mace specialized in the seventh form of lightsaber combat, AKA Juyo or Vaapad. Windu was the only known practitioner of this form that didn't fall to the Dark Side, mainly because the style calls for an aggressive, unpredictable approach (much like Maul's, just less jumping around).
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.
Proficient in its use, Jedi Master Depa Billaba taught her students, including Caleb Dume—who changed his name to Kanan Jarrus after Order 66—to use Form III during close-quarter fighting.
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.
An example of a Jedi swordmaster was Mace Windu, considered as such because he was a master of all forms of lightsaber combat and due to his mastery of Vaapad, which he created.
