Ataru

"Ataru is the name given to the movements of this form—though it is aggressive, it is focused, and its best use is in combat against a single opponent." ―Zez-Kai Ell

Form IV, also known as Ataru, the Way of the Hawk-Bat, or The Aggression Form, was the fourth of the seven forms of lightsaber combat. The history of Ataru stretched back through the Old Republic, to at least as early as the Mandalorian Wars, where it was commonly employed by Jedi of that day. Ataru continued to be a common form among the Jedi in the latter stages of the Republic and was also known to be employed by the Sith.

An aggressive style, Form IV was fast-paced and effective against single opponents, though weaker in prolonged combat and confined spaces. Also, it was not recommended for use against opponents wielding blasters. Ataru was characterized by Force-assisted acrobatics, such as somersaults and leaping strikes, both for attack and defense. Another characteristic of the form was its fast, powerful strikes from multiple directions.
Ataru was an aggressive combat form relying on a combination of strength, speed, and agility. Due to this, it was also called the Way of the Hawk-bat or the Aggression Form. Practitioners of Ataru were always on the offensive, attacking with wide, fast, and powerful swings. Form IV practitioners constantly called upon the Force to aid in their movements and attacks. By allowing the Force to flow throughout their body, they could overcome their physical limitations—including old age, as was the case with Master Yoda—and perform amazing feats of acrobatics, such as somersaults and backflips, not only for an attack but also to evade the slashes and strikes of their opponents. Jedi utilizing Ataru needed to incorporate all the Force powers that involved surpassing normal physical ranges of motion, speed, and agility in order to be successful. Running, jumping, and spinning were all emphasized in learning the elaborate kinetics of the form.
Those who used Form IV could move at high speeds and could rain strong blows, jumping and attacking through the air. Powerful and quick spinning attacks could be utilized from all angles, either from ground or air. Masters of Ataru combat could appear like a blur to their opponents, attacking from all directions—the front, the sides, overhead, or behind. The Force not only allowed them to perform athletic feats not possible otherwise, but it also helped guide their actions and movements in combat.

Form IV uses acrobatics and the environment to gain an advantage. This form is deadly against slow opponents.
