Form V is a powerful style developed by Form III practitioners that preferred a more offensive angle. The defensive nature of Form III dangerously prolonged combat. The maxim "peace through superior firepower," encompasses the philosophy of Form V, also called the "Way of the Krayt Dragon." Anakin and Luke Skywalker are both practitioners of Form V.
Form V focuses a bit on having defensive skills, but channelling defence into offence. The example is commonly used that while Form III combatants effortlessly deflect laser bolts, Form V practitioners excel at redirecting the laser bolt toward the opponent.
