These are the next installments of the LEGO Ninjago series that will come out in 2019. Bragi Schut, who previously worked on 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 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 likely means any lose 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.
 * 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.
 * 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.
 * 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.
