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.
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.
Unlike other forms, Juyo encouraged Jedi to embrace their emotions and use them to fuel a relentless assault. Consequently, Form VII was outright banned by the Jedi for a long time. However, Jedi Master Mace Windu took it upon himself to refine Juyo into an offshoot known as Vaapad: the perfection of Form VII.
The black lightsaber, or Darksaber to give it its proper name, is one of the rarest lightsabers in Star Wars canon. Despite its rarity in canon, anyone who has seen the second season of The Mandalorian is likely to be familiar with the Darksaber.
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.
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.
Palpatine mastered all seven forms of lightsaber combat but preferred Form VII, Juyo. This seventh form was ideal for Sith Lords, utilizing their aggression for a ferocious form that favored offense.
Ahsoka Tano and Darth Vader, both skilled users of Form V, clash on Malachor. Anakin Skywalker was very skilled at Djem So and showcased his mastery over the form during the Clone Wars.
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.
A prime example is Kit Fisto. Kit Fisto was a Skilled Jedi of form I who fought during the clone wars. He almost defeated general Grievous using Form I of lightsaber combats. Other than Fisto, Meera Sutrik, and Obi-Wan Kenobi are the notable names to use Form I of lightsaber combats.
By the time of the New Sith Wars, the Sith Blademaster Kas'im had mastered Form III as well as the six other forms. Kas'im trained several apprentices in the style, including Fohargh, who used it against Bane's Form V. Bane himself possessed considerable skill in the Form, training his apprentice, Darth Zannah, in it.
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.
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.
Legend had it that Yoda—a Jedi who became Grand Master—was trained by N'Kata Del Gormo. A Force-sensitive Hysalrian, N'Kata Del Gormo was trained in the ways of the Force and achieved the rank of Master within the Jedi Order.
For much of the Clone Wars, Anakin used Form V in battle. Darth Vader also used lightsaber Form V, and the idea behind this technique was to end a fight before it could be allowed to begin. It was a heavy-handed style and executed with aggressive, powerful strikes.
Salvatore, Dooku's fighting style is described as “balanced” and “arcane…more front and back, thrust and riposte, than the typical circular movements currently employed by most of the Jedi.” The character's imposing abilities were matched by a distinctive curved lightsaber hilt that caught the attention of many fans.
Princess Leia Organa's preferred form is never specified, but her training in both continuities indicates that she also prefers Form V. Form V, with its two sub-disciplines of Shien and Djem So, is a fast and aggressive lightsaber form, focusing on overwhelming and overpowering opponents.
As with his clone precursors, Starkiller was programmed with the knowledge and skills of his genetic template via memory flashes. As such, he inherited the original Starkiller's preference for the Form V/Shien-style reverse grip, as well as the Form IV/Ataru and Form VI/Niman fighting styles.
However, a groundbreaking study conducted at the University of Leicester's Centre for Interdisciplinary Science challenges these long-held assumptions. The study suggests that, against all expectations, red lightsabers may actually be the weakest of the lot.
Black lightsabers are extremely rare in the Star Wars universe, and only a few have been seen on screen. These lightsabers are typically associated with the Dark Side of the Force and wielded by Sith or Dark Jedi. The most well-known black lightsaber is the Darksaber, which was created by the first Mandalorian Jedi.
