853866

LEGO set 853866, Oni Villains Accessory Set, is a Ninjago accessory set released in 2019. It represents Oni villains and contains 36 pieces with 3 minifigures, intended to expand scenes and collections within the Ninjago theme.

Oni Villains Accessory Set belongs to the Ninjago theme and focuses on Oni antagonists rather than on a vehicle or a main build. Its role is as a character supplement, useful for adding opponents to conflict scenes, faction displays or story setups involving the ninja’s enemies.

The set contains 36 pieces and 3 minifigures named in the Rebrickable data: Oni Villain with Large Horns (Omega), Oni Villain and Oni Villain with Short Legs. The build is that of a small accessory set, with emphasis on the figures and their supporting elements. No specific mechanical function is documented in the supplied facts.

It is suited to Ninjago minifigure collectors, display builders and play scenarios that need additional identifiable villains. Within the theme, it is best understood as a cast expansion: it does not provide a large model, but it strengthens the Oni presence in a Ninjago collection.
