Oni Trilogy

The Oni Trilogy is the third arc in the Ninjago Masters of Spinjitzu series. It tells an overarching story about the Oni and the heritage of Lloyd, Garmadon, and Wu.

The Ninja are at their peak, and after the loss of Wu, they train in order to face their deadliest foe yet: the Oni. The Bringers of Doom are hinted at since the beginning of Season 8, until it leads to the final battle in Season 10. This phase can also be seen as a focus for Lloyd as a whole, as he plays a big part in all 3 seasons.

The focus characters of this arc, in order, are Lloyd, Wu, and Garmadon. Each season focuses on one of the descendants of the First Spinjitzu Master.

The seasons the arc is made up of are the Sons of Garmadon, Hunted, and March of the Oni.

It is preceded by the Master Trials and succeeded by the Book of Elements. A midquel between this season and Season 11 was released to tie together the loose ends that remain after changes made titled The Splinter in the Blind Man's Eye. It has been written by Tommy Andreasen on Twitter since 2021. It is considered "could-be-canon," as it doesn't conflict with canon, and serves to answer the remaining unanswered questions that March of the Oni left.
