Out of StockAbout LEGO Arin's Spinjitzu Battle Mech
Arin's Spinjitzu Battle Mech features fully posable arms and legs with a rotating torso mechanism, allowing dynamic action poses during play. The 213-piece set recreates scenes from season 3 of the NINJAGO Dragons Rising TV show, designed for builders aged 7 and up.
The mech stands over 16 cm tall and includes an opening chest compartment that can hold a minifigure inside. Two large sword accessories complete the warrior's equipment, while the articulated design enables authentic battle stances and movement.
Minifigures and Accessories
The set includes two NINJAGO minifigures: Arin equipped with a crystal katana sword and a Spectral Dragonian Warrior for opposing faction battles. A Baby Riyu model adds an additional character element to the build.
Customisation Features
Body parts and weapons from this mech can be mixed and matched with other customisable mechs in the 2024 NINJAGO range, allowing builders to create personalised ultimate mech combinations through modular construction techniques.
