Darth Vader, a master of Form V since his early days as a Jedi Knight, became much stronger after he became a cyborg. After turning to the dark side in 19 BBY, Anakin Skywalker, now known as Darth Vader, dueled and was nearly killed by his former Jedi Master, Obi-Wan Kenobi, on the planet Mustafar.
Vader's new hybridized of Djem So consist elements from all seven lightsaber forms, which Vader became a master of each form. In his final duel with Obi-Wan, Vader's mastery in Form III was so perfect that Obi-Wan was unable to find an opening for an attack.
During the Great Jedi Purge, the Sith Lord Darth Vader studied and mastered Form II and he often incorporated many elements of Makashi into his personalized Djem So variant, taking advantage of his cybernetically augmented strength to overcome Makashi's prime weakness.
After his defeat in the Duel on Mustafar, Vader himself studied Form VII and became versed in it, at times applying elements of Juyo as part of his customized variant of Form V, employing some of its techniques when he killed the resistance fighter, Roan Lands, who was a good friend of the former Jedi Ferus Olin.
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.
Form V, also known by its two primary disciplines of Shien and Djem So, as well as The Way of the Krayt Dragon or The Perseverance Form, was the fifth of seven forms recognized as canon by the last Jedi Council for lightsaber combat.
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.
Notable practitioners
In more recent years, the form was mastered by the Jedi swordmaster Cin Drallig along with the other six forms. 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.
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.
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.
The oldest of the seven lightsaber forms, as well as the most basic, is Shii-Cho form, otherwise known as The Way of the Sarlacc and The Determination Form. Shii-Cho is traditionally the first lightsaber form taught to Jedi initiates.
There are 7 forms of lightsaber combat, but Soreso, Shein, and Vaapad are the most effective. Soreso, Vaapad, Shein, are the most effective forms because they are all strategic and have their strengths and weaknesses.
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.
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).
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.
A notable Jedi adherent was Johun Othone, who took full advantage of Form VI's inherent versatility during the pitched battles of the war.
Luke Skywalker's Lightsaber Style Matches His Father's
In some ways, it makes sense that Luke developed Form V. After all, it is the form he observed the most. The first duel he witnessed had Darth Vader use Form V against Obi-Wan.
During the New Sith Wars, Form V was mastered by the Sith Brotherhood of Darkness' Blademaster Kas'im, who instructed numerous apprentices and acolytes in its use, including Darth Bane.
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.
