Dragons Rising (2023)
The new season of NINJAGO begins with a shocking twist: A mysterious enemy has travelled through time and altered key events in Ninja history, creating a dangerous alternate timeline. The Ninja team must race against time to find a way to set things right before it's too late. But the task proves more difficult than they ever imagined, as they battle new enemies and struggle to keep their own memories of the original timeline intact. Travelling through time, they soon stumble upon a long-forgotten race of Dragons, powerful beings who hold the key to restoring the timeline. But the Dragons are guarded by a ferocious and cunning Dragon Hunter who will stop at nothing to destroy anyone who threatens his power. With the dragons and their incredible abilities, the Ninja must outsmart the Dragon Hunter in an exciting race against the clock. But as the stakes get higher and the enemies become more powerful, they must also confront their own demons.

Series Impact

 * An event known as the Merge occurs in the beginning, merging together all sixteen realms and causing chaos, and the Ninja are separated. Lloyd and Kai remained at the Monastery.
 * Nya was sent somewhere and ended up in the Kingdom of Madness, what was once the Realm of Madness.
 * This marks the first appearance of this realm since Season 2, and the first appearance of the Craglings since then.
 * In Episode 3, Lloyd attempts to train Sora and Arin in the same way that Master Wu originally trained Kai in the Pilot Episodes.
 * The Cloud Kingdom reappears in Episode 5, making its first reappearance since Season 5. It is revealed in this season that the "writers of destiny" claim that their writings predict destiny but are often wrong. This seems to be a retcon of the events of Possession, since we do see that their writings do in fact alter fate.
 * Since the last appearance, the previous Master Writer, who helped the Ninja defeat Fenwick, has stepped down as Master Writer and been replaced with someone else. It may be that they cycle through Master Writers frequently.
 * A new type of Dragon is revealed, Source Dragons, who appear to have the power to enhance Elemental Power.
 * A new character, Sora is introduced with the Elemental Power of Tech, which she is able to access with the Source Dragon Riyu's help.
 * The new Master of Wind has been introduced, being a writer in the Cloud Kingdom.
 * Morro is referenced by Lloyd when he says he knew who the last Master of Wind was and likes the new one better.
 * There is a reason why Ninjago was the epicenter of the Merge, but it is currently unknown.
 * In Episode 9, a flashback is shown that takes place sometime between Rise of the Snakes and Legacy of the Green Ninja with Master Wu training young Lloyd.
 * In the flashback, Lloyd has his green eyes, which is an error, as he obviously didn't get them until Sons of Garmadon. He also wears his Legacy Gi, which isn't too big of an issue.
 * He also is played by Sam Vincent and not Jillian Michaels.
