71839

LEGO Ninjago 71839, Arin's Spinjitzu Battle Mech, depicts a battle mech connected to Arin within the Ninjago theme. Released in 2025, it contains 213 pieces and includes 2 minifigures for a scene involving a spectral Dragonian warrior.

This set belongs to the LEGO Ninjago theme and focuses on Arin with a Spinjitzu related battle mech. The subject fits the action led side of the theme, where character driven machines provide a larger build around a ninja figure and support direct conflict based play.

The build uses 213 pieces and results in a mech model intended for handling and scene building. Rebrickable lists 2 minifigures: Spectral Dragonian Warrior, Ghost Lower Body, and Arin, Black Hair and Mask. The included character pairing gives the model an immediate opponent for Arin, rather than presenting the mech as a display object without narrative context.

It is suited to Ninjago play, small shelf scenes and collectors who follow Arin or mech based releases within the theme. In a broader Ninjago collection, it can be placed among compact character mechs, with its identity defined by Arin and by the spectral Dragonian adversary included in the box.
