|“No. I have warned you before about the dangers of time travel. Change anything, change everything. In this time, you do not exist yet.”|
|— Wu to the Time Twins|
Time Travel is the concept of movement between certain points in time, such as the past or the future, analogous to movement between different points in space by an object or a person, typically using a hypothetical device known as a Time Machine.
The Ninja traveled to the past to stop Lord Garmadon who traveled many years before Lloyd became the Green Ninja, finally defeating him using the Golden Weapons of that time and sending the Mega Weapon into space.
The Ninja and Garmadon mention the events that happened in "Wrong Place, Wrong Time."
Nya, Kai, and Wu travel 40 years into the past, moments after the defeat of Young Acronix and Krux, to stop themselves from the future who traveled there to defeat Wu, Garmadon and the Elemental Alliance. Finally Wu sacrifices himself, and he along with the Time Twins are lost in time, while Kai and Nya return to the present.
- The Ninja have traveled twice to the past, the first time in "Wrong Place, Wrong Time" and the second in "Lost in Time."
- Lloyd is the only Ninja who has yet to travel through time.
- In The LEGO Ninjago Movie, the Ninja originally travel to the past to prevent Garmadon from becoming evil, as well as facing the snakes and The Great Devourer.
