Season 10: March of the Oni

These are the next installments of the LEGO Ninjago series that will come out in 2019. Bragi Schut, who previously worked on both Sons of Garmadon and Hunted, is the lead writer on them. The Hageman Brothers are involved with the creation of the story but are not the script writers. One of them is a four episode special event with each episode being 22 minutes long, and adding up to a full 88 minutes. The special event is only a small part of the six (potentially eight) hours of content planned. The rest of it is yet to be announced.

Trivia

 * Tommy Andreasen stated that the four episode special event serves as "a conclusion of a 24 episode arc." this may mean that any loose ends left open at the end of "Green Destiny" will be concluded by the end of these 4 episodes.
 * The four episode special event is planned to be released early 2019.
 * On July 15, 2018, Tommy Andreasen tweeted a sneak peek image for Ninjago's storyline in 2019. It was revealed in full detail during San Diego Comic Con on July 22, 2018, and will be about Jay proposing to Nya.
 * Tommy Andreasen stated that Jay's proposal to Nya may not have to do with marriage.
 * Tommy Andreasen stated that episode 97 is "the most intense episode in the series yet" . He also stated that episode 97 is his favorite.
 * Dareth is set to appear in this installment.
 * The final episode of Hunted, "Green Destiny," hints that future villains will most likely be the Oni, as Lloyd believes they are coming. Though it is unknown if this is in the special-event, or in the installment after it.
 * A clip was released (in its early animation) of Jay practicing asking out Nya with Kai in the Monastery of Spinjitzu. It is revealed through the clip that the emblem is what Jay uses to ask Nya to be his Yang.
 * The original Monastery is as good as new in the clip, despite being burned down by the Hypnobrai in Season 1 and again accidentally by Kai in Season 7. It appears that two people are reattaching the door of the Monastery, meaning that the Ninja are restoring it and have moved back into it as their home base.
 * It was confirmed in the summary for a book that the Monastery was rebuilt by the Ninja.
 * A new character called Antonia will appear in 2019, but it is unknown if it will be in the special event.
 * Tommy Andreasen also stated that the episodes of the special event will have an intro sequence but it will be different from any previous ones.
 * It was once again revealed on Tommy Andreason's Twitter, that Ninjago would be around "for a long time".
 * During the San Diego Comic Con panel, Tommy Andreason revealed that the special event's name spoils the end of Hunted.
 * The special event will reveal how long it takes place after the end of Hunted.
 * There will be scenes of the Ninja casually hanging out, similar to when in season 1 when the ninja were on the TV playing a video game.
 * As of September 11, 2018, animation for the special event is done, and two episodes have finished rendering.

Leaked Info

 * Several things about the Winter 2019 wave of sets were revealed on images found on an online database of LEGO pieces. It is unknown how they relate to the plot of the special event.
 * Although the sets appear to be based off of material from the earliest seasons and sets, the mini-figures all have new designs.
 * The Overlord will get a brand new figure, with four-arms (the upper-torso looking similar to the Golden Armor), a translucent head, and a ghostly tail (like the ghosts of Possession, and Djinn such as Nadakhan).
 * It was also leaks that Kruncha and Nuckal will reappear, with head molds similar to Wyplash.
 * The Ninja have a new one-piece mask mold that is similar to the masks used for the Deepstone to Fusion suits.

 * Kai's gi looks very similar to the original and DX (Dragon eXtreme) gis.
