Form IV, also known as Ataru, 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, and was best suited for open spaces. When the Galactic Republic was in its last years of existence, Anakin Skywalker made adjustments to the classic Form IV techniques and demonstrated them in a holographic recording, later found in Kanan Jarrus' holocron.
