Arin | Arin is a self-taught Spinjitzu prodigy, creator of Object Spinjitzu, and a former ninja student of Lloyd's. He is the first known person to teach himself Spinjitzu without a master. He used to live in a neighborhood outside Ninjago City, until the Merge caused his parents and region to disappear. Multiple years after the Merge, Arin and his best friend Sora became students of the Green Ninja, Lloyd Garmadon, after saving a dragon called Riyu. With the help of the other original ninja, Arin helped to free most of the dragons from Imperium. He and Lloyd searched for the Pink Dragon Core, defeated Beatrix, and helped to stabilize the Merged Realms during the MergeQuake Storm, where he briefly saw his parents through a rift. A year later, Arin helped the other ninja to handle Lobbo being mutated, stopping the Mechanic, and stopping the Lava-Tides from stealing dragon eggs.
