Ninjago is a city within the Lego Universe that is frequently attacked by the evil Lord Garmadon, who is the father of Lloyd Garmadon and husband of Misako (AKA Koko). Ninjago despises Lloyd for being Lord Garmadon’s son, which puts Lloyd under emotional stress. They do not know that Lloyd is part of the secret ninja force, consisting of Nya, Zane, Jay, Cole, Kai and their master named Wu, who always stop Garmadon from taking over the city by fighting with mechs. On Lloyd’s birthday, Garmadon attacks the city once again only to be defeated. He escapes and fires nine generals of his Shark Army for failing to help him. He then begins to plan a big attack to conquer Ninjago, and his GIT`s show him plans to build a gigantic mech that is immune to weapons.
Meanwhile, Lloyd and his friends see the return of Master Woo, back from a long trip he took. Master Woo tells them they aren’t real ninjas if they use only mechs to fight, and discusses with Lloyd that his element is green, confusing Lloyd. Master Wu tells Lloyd he must not be angry at Garmadon; he must use his mind to fight. Wu mentions an Ultimate Weapon, giving Lloyd the hope of defeating Garmadon once and for all, despite being forbidden to use the weapon.

As Garmadon celebrates his victory, Lloyd reveals that he is the Green Ninja, and tells Garmadon that he wishes he wasn’t his father, leaving Garmadon confused.
