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.
Form I: Shii-Cho
When learning lightsaber techniques, a Jedi or Sith apprentice is trained to recognize all seven forms of combat.
Cin Drallig had mastered all seven forms. He was a helluva Jedi. He was the order's Battlemaster all through the Clone Wars, both head of the temple guard and the head lightsaber instructor.
In the original trilogy, because Luke never had much in the way of combat training, then his combat style doesn't completely fit one of the seven recognized lightsaber forms. He fights on instinct and, on occasion, with anger, using strong offensive blows against Vader.
Mace Windu was a Jedi Master who was skilled in several forms of lightsaber combat, including Form 7, Juyo, and Vaapad. Mace Windu was a master in all seven forms of lightsaber combat.
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.
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.
Classical Juyo
Juyo was described as the most vicious form of lightsaber combat and was said to be filled with both fury and "malignant grace." The form was given the title of the most difficult and demanding form in all of the lightsaber combat.
A notable Jar'Kai master was the Priapulin Jedi Master Skwelli, who carried six lightsabers. He was renowned for his skill in his era, and recordings of his fighting form were considered a wonder to behold.
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.
Darth Maul had mastered this form and employed it in his duel against Obi-Wan Kenobi in the Theed power generator.
Obi-Wan Kenobi used Form III.
On the Jedi side, Jedi Battlemaster Skarch Vaunk was also versed in Form V. To the Jedi of the Clone Wars era, the most prominent practitioner of Form V was Anakin Skywalker, who mastered both Form V variants.
The Sith apprentice Darth Maul wielded a double-bladed lightsaber made by joining two hilts together end-to-end. Maul's dexterity and extensive training allowed him to use his weapon as a single-bladed saber, or to activate both crimson blades and fight multiple opponents at once.
The lightsaber that Mace Windu wields throughout the prequel trilogy is one of the most unique laser swords in the franchise simply due to the color of the blade. Jedi lightsabers are typically green or blue, as highlighted by the Battle of Geonosis, but Mace Windu's weapon has a distinctly purple blade.
Other than Lucien Draay, Meetra Surik, Obi-Wan Kenobi, and Kit Fisto, Shii-Cho had many advanced and/or specialist practitioners. In more recent years, the form was mastered by the Jedi swordmaster Cin Drallig along with the other six forms.
Tenel Ka Djo, the Princess of Hapes, had a tiara of rainbow gems worth the price of an entire solar system. She used some of the crystals in her second lightsaber, after her first one malfunctioned and led to the loss of her arm.
Obi-Wan soon arrived with a battalion of clones, and the Battle of Utapau began. The General and Obi-Wan dueled, and despite wielding four lightsabers at once, Grievous was dismembered and once again tried to flee.
Yoda was considered to be the greatest swordmaster of his time, alongside the likes of Mace Windu, Count Dooku, Darth Vader, and Darth Sidious.
Kathracite crystals were the weakest of the Adegan crystrals and often used to create training lightsabers for the younglings who were apart of the Jedi Order. They produced a weak pale green blade which produced very little heat and was impossible to inflict wounds.
During his years as a Jedi, Obi-Wan Kenobi fought with three lightsabers. His first had a blue plasma blade and a hilt similar to that of his master, Qui-Gon Jinn. Obi-Wan used this weapon until Darth Maul kicked it into a deep shaft on Naboo.
Whose Lightsaber Does Rey Have at the End of The Rise of Skywalker? In addition to her own yellow lightsaber, Rey Skywalker has Leia's lightsaber and the Skywalker lightsaber (which belonged to Anakin, Luke and Rey herself) at the end of The Rise of Skywalker.
Form IX: Kadeesh was a Form of lightsaber combat mainly focusing on the use of brute strength rather than Force-assisted movements or fancy and unpredictable parries.
