Episode Title:Green Destiny.Episode Description:Wu and the four Ninja are finally back home and reunite with their friends. Nya takes Skylor to safety, while Kai, Jay, Zane and Cole rescue the civillians and fight Colossi, and Lloyd and Wu confront Garmadon. The Elemental Masters and the Ninja's other allies escape from Kryptarium prison and help the Ninja defeat Colossi, while Garmadon defeats Wu and the Firstbourne Dragon, leaving only Lloyd to fight him. After understating that fighting is what gives Garmadon his powers, Lloyd stops fighting him and just "resists him", by using the Art of the Silent Fist. This takes away all of Garmadon's powers and restores Lloyd's. Thus, Garmadon is finally defeated, but he warns Lloyd that his powers were the only thing strong enough to prevent some dark forces from attacking Ninjago, and now that they're gone, "they" will come and destroy everything. In the aftermath, Colossi gets destroyed and all the Sons of Garmadon, including Garmadon, are arrested; Skylor gets back to normal; and the people of Ninjago celebrate the Ninja and their allies. Lloyd meets with Wu, now back to his normal age, who tells him that the Firstbourne and the other dragons have to go back to their realm, and will return only when they'll be needed again. Lloyd then tells Sensei Wu about his father's warnings and, after hearing that all the Oni are gone from The First Realm, he concludes that "they" are the Oni, and that “they†are coming.
