The set was first revealed in May 2018 as a Toys "R" Us exclusive. By that point, however, Toys "R" Us was in the final stages of closing, which threw the set's release into limbo.
On August 23, official images of the set were revealed through a German magazine - this time as a limited edition set instead of a Toys "R" Us exclusive. The same day, LEGO confirmed it will be available at Barnes & Noble locations in the United States later in the year.
- All the set's minifigures are exclusive, and represent different parts of the series. Kabuki Nya is from season four, Future Jay is from season five, and Mohawk and Harumi's "hatred form" are from season eight.
- This is also the only set to include any variations of Mohawk - Harumi, Jay and Nya have appeared in other sets, but with different appearances.
- All the set's minifigures have printing on their arms - something the previous Bricktober set didn't feature. Nya also has her arm bracelet for the first time, which she wore for much of the series.
- Harumi's Oni Mask of Hatred is exclusive to this set, as it features unique printing compared to other versions. With this version, the mask's mouth is open.
- This is the second and last Ninjago Bricktobrer Pack.
