Spinjitzu is a martial arts technique used by the characters in the Ninjago universe. It involves spinning rapidly to create a powerful force, allowing the user to perform various attacks and defensive maneuvers. This technique is often associated with the elemental powers of the Ninjago ninjas, enhancing their abilities in battle. The practice of Spinjitzu is taught to young ninjas at the Monastery of Spinjitzu, where they learn to harness their elemental powers. Each ninja, such as Kai, Lloyd, and Zane, has a unique connection to their element, which influences how they use Spinjitzu in combat.
