Victory in the Final Battle between the Golden Ninja and the Overlord has ushered in a new era of peace and begun a technological renaissance. NINJAGO City has been rebuilt into a futuristic wonder and is now completely interconnected. Welcome to New NINJAGO City. The ninja have found there is very little need for their heroics and have become teachers at Wu’s Academy. But peace is an illusion… During a ninja-led class trip to Cyrus Borg’s amazing Borg Tower, the heroes discover the Overlord has survived in digital form in Borg’s virtual Digiverse. His plan: escape the Digiverse, using the Lloyd’s Golden Power, and conquer the world as the great prophesized destructor, “The Golden Master.” With the aid of a mind-controlled Borg and an army of Nindroids, the Digital Overlord is more dangerous than ever. Seeing this, Wu allows himself to be captured so that the ninja can escape with the Techno-Blades, the only weapons that can reboot the system, destroying the Digital Overlord. Zane, meanwhile, has met Pixal, Borg’s android assistant, who will become an important friend and ally to him. The ninja succeed in destroying the Storm Farm that provides energy to the Nindroids, but Pythor returns and allies with the Digital Overlord. Using Electro-Cobrai stolen from the aquarium, Pythor brings the Nindroids back to life. Lloyd is captured and some of his power is siphoned off to aid the Digital Overlord’s schemes. The heroes enter the Digiverse in an effort to save Lloyd and Wu and erase the evil for good. They succeed in using the Techno-Blades to reboot the system, but they have struck too late. The Overlord has escaped into the physical world. To prevent the Overlord from becoming the Golden Master, Lloyd gives up his Golden Power. The ninja head into space to stop the Nindroids’ attempt to retrieve the Mega Weapon, the remnants of the Four Golden Weapons, but fail. Returning home, they find the Overlord has become the Golden Master and is attacking New NINJAGO City. When their every effort to stop him fails, it takes Zane sacrificing himself to stop the villain once and for all.
