Form IV (Ataru, the Way of the Hawk-Bat, The Aggression Form) is the fourth lightsaber form created for combat.
It is believed that the history of Ataru goes all the way back to around the Mandalorian Wars.
It is an aggressive style that is fast-paced and is very effective against single opponents. It is used for force-assisted mobility and opposition and requires the user to constantly stay on the offense. This involves kinetic and broad moves like jumps, twirls, etc. Form IV requires speed, strength, and agility. Ataru practitioners also use unarmed combat attacks chained together with their lightsaber. However, Ataru has several flaws that user must overcome. First, it provides no defense against blasterfire. Second, since it focuses on aggressive combat to overwhelm a single opponent, it is terrible against multiple opponents. Third, it is useless in confined spaces. And fourth, Ataru requires a large amount of stamina, causing the practitioner to become exhausted rather quickly. Notable practitioners are Yoda, Quinlan Vos, Qui-Gon Jinn, Aayla Secura, Darth Maul, Mara Jade Skywalker and Zez-Kai Ell.
“The Ataru form of combat is aggressive, but focused. You must never rely soley on skill with a weapon, but rather embrace the idea that your whole body is the weapon. Use the Force to spin, jump, to overpower your foe.” - Luke Skywalker
AKA The Aggression Form or The Way of the Hawk-Bat.
“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.”
Form IV is, simply put, the direct opposite of Form III. While Soresu is the unyielding defence, Ataru is the crushing offence. The Form IV users are known for being either incredibly agile or devastatingly strong, doesn’t matter if it’s attacking or blocking.
The whole body of the practitioner is a weapon, not just the lightsaber. Punches, kicks, leg sweeps, whatever is needed goes.
Positive Aspects: with the Force-boosted strength and agility, strikes come from almost any direction, with blade and body rotating in any of three axis.
Form IV users know the battle has to be ended quickly so they do it in such a manner that the rest of their opponent won’t feel like they should engage in newer combats - that is, if anyone is left standing.
Negative Aspects: like Form II, Form IV is weak against many adversaries and blaster fire, but that can be overcome with honed skills.
Ataru also demands a lot of space for most of its “performance”, making cramped spaces the worst place for a Form IV user.
Also, unlike Makashi, Ataru users are very susceptible to tiredness and fatigue. The longer the battle takes, the harsher it gets to the practitioner to keep up with the battle rhythm and the easier it is for their defence to be left open.
