Since Lord Garmadon’s disappearance from the Underworld, Ninjago has been at peace; but when Garmadon’s son, Lloyd, releases the five ancient warring tribes of the Serpentine, the Ninja had to learn how to unlock their full potential in order to combat the growing threat. The Ninja also learned of a prophecy that one of them will become the Green Ninja – a warrior destined to defeat the Dark Lord in the ultimate battle of good versus evil. In the first season, the Ninjas unlocked their full elemental powers. Meanwhile, the Serpentine released the all-consuming snake known as the Great Devourer. In the climactic finale, the Ninja had to rely on Lord Garmadon and his ability to wield the Four Golden Weapons in order to destroy the Great Devourer and bring peace. In the end, the Ninja are heralded as heroes, but Lord Garmadon has disappeared with the very weapons he needed in order to turn Ninjago into his evil image.
