|“Where are we?”|
“Long story, but we're back in time. Forty years. When you, Garmadon, and the Elemental Masters fought Krux and Acronix at the Monastery.”
|— Wu and Kai in "Lost in Time"|
Shortly after the Serpentine War and the banishment of Chen and Clouse, the Elemental Alliance was celebrating their recent victory against the Serpentine, two of these celebrants being the Hands of Time. Acronix and Krux, the Elemental Masters of Time, betrayed the Elemental Alliance, believing that they had the strongest Elemental Power in Ninjago. Wu and Garmadon gathered the Elemental Alliance to fight the Hands of Time, but they were outmatched.
Wu, seeing his team losing, gathered Ray and Maya and asked them to forge four blades made of Chronosteel. Ray and Maya used all their energy to create the Time Blades to the point where they were unable to walk. One evening, Wu comes and gathers the Time Blades from Ray and Maya. But Ray and Maya became too tired to join Wu in the fight and stayed behind. Wu returned to the monastery, leaving the gate open so that the Time Twins would come.
A raging battle between the Time Twins, Wu, and Garmadon broke out. The Twins, unaware of the Chronosteel Time Blades, tried using their powers against the brothers, who were holding the blades. This powered the Time Blades with the four elements of time (Forward Time, Slow Motion Time, Pause Time and Reversal Time). Wu and Garmadon then created a temporal vortex using the four blades and allowed the Time Blades to be sucked into the vortex. The Time Twins did not surrender, instead they followed the Time Blades and entering the vortex. At this time Wu saw a blimp that showed Acronix's return forty years in the future.
After the battle
Shortly after the defeat of the Time Twins, the Elemental Alliance was divided to continue with their lives and, without any enemy, some decided to have children. Among those children who would eventually become the ninja are Kai, Nya, Jay, Cole, and Lloyd.
Shortly after the Time Twins were lost to time, another temporal vortex opened up. It released Krux and the Reversal Time Blade. Krux also saw the blimp that showed his brother's return, though he did not notice the Reversal Time Blade, which fell just a few feet away moments after he ran off. Ray and Maya found the Reversal Blade in the woods soon after, and following Wu's orders, hid it in the Boiling Sea. Krux knew that he now had forty years to prepare for the return of Acronix. He took on the alias of Dr. Sander Saunders and created the Ninjago Museum of History as a way to cover his identity. He created a secret room in the Ninjago Museum of History which had sewer systems leading to an open swamp. There, he began to breed the Great Devourer's eggs in order to create warriors. Krux decided to prepare his warriors and he needed armor to do it. Krux pretended to be Ray and Maya's friend until one day when they were chatting, Krux turned on them, told them of his brother's return, and forced Ray and Maya to work for him under the threat that he would kill Kai and Nya. Somehow during this time, Chen found out about what had happened to Ray and Maya.
Master Wu goes to the burnt down Monastery of Spinjitzu, where Acronix returns along with the Forward Time Blade. Acronix and his brother soon re-unite and kidnap Cyrus Borg to build them an apparatus for a temporal navigation system that can withstand the power of all four Time Blades. The shell is designed by Ray and Maya. The Time Twins capture civilians to build the shell of the temporal navigation system, which is named the Iron Doom. Slowly, the Time Twins gather all four Time Blades and open a temporal vortex in order to travel back to the beginning. However, with the help of their parents, Kai and Nya create a fusion dragon and follow the Time Twins.
Moments after Acronix and Krux's former selves are lost to time, the future Acronix and Krux arrive with the Vermillion and the Iron Doom and engage in another battle with the Elemental Alliance. This time the Time Twins begin to win. Kai and Nya arrive and pretend to be their parents, and tell Wu and Garmadon the secret to defeating the Vermillion. However, The Time Twins initiate a Vermillion protocol on the Iron Doom and defeat the Elemental Alliance, making younger Wu surrender. This causes history to change, erasing modern technology.
Kai and Nya conjure up their fusion dragon to try and fight the Iron Doom. Nya leaves Kai on the dragon while she fetches the Reversal Time Blade from the past. Kai tries to attack the Iron Doom, but it opens a temporal vortex and travels through it, leaving Kai, Nya, and the rapidly aging older Wu stranded. However, with the help of the past Reversal Time Blade, Kai and Nya heal Wu and throw the previous Reversal Blade into the hands of young Wu, who hides it in the Boiling Sea. The future Kai, Nya, and Wu follow and lose the Time Twins in time once more, ending the battle for all of time.
