Lightsaber Styles - Seven? A Quick Question

Your best source would be from SW-Insider Magazine. Here's a quickie breakdown:

Form I: Basic lightsaber combat, based on ancient solid weapon techniqes. Form I is taught to all Padawans as children.

Form II: An archaic style, based on 'saber vs. 'saber combat. Fallen into disuse. Count Dooku is a Form II master.

Form III: A defensive style. Obi-Wan Kenobi begins learning Form III after Qui-Gon's death, and has mastered it by the time he faces Vader on the Death Star.

Form IV: A stunning, acrobatic style with Force-assisted leaps & flips. Obi-Wan (as a {Padawan) and Qui-Gon were practitioners, and Yoda was a master of the Form.

Form V: Powerful, aggressive style. Also good for reflecting blaster bolts at the attacker. The philosophy was "peace through superior firepower." Practitioners were Anakin Skywalker & Luke Skywalker, and Vader was a Form V master. As an aside, Luke displayed the amazing ability to learn Form V instinctively while it was being used against him.

Form VI: The "diplomat's form." Very little technique, which allowed a Form VI practitioner to focus on social skills of diplomacy & observation. All Form VI practitioners who fought at Geonosis died.

Form VII aka Vaapad is still under development. Form VII practitioners were Mace Windu, Depa Bilaba, Sora Bulq, and (according to the article) Darth Maul.

 

62 or 63, I think.
