About LEGO Rontu the Master Dragon

Rontu the Master Dragon brings impressive scale and articulation to the NINJAGO Dragons Rising collection, featuring 381 pieces that build into a highly posable dragon figure standing over 13 cm tall. The dragon model offers exceptional movement with a posable tail, legs, wings, head and jaw, plus two positions on its back for minifigure riders and a stud shooter under each wing for aerial combat play.

The set recreates scenes from season 3 of the NINJAGO Dragons Rising TV show, centring around a brick-built shrine guarded by the villain Zarkt. This shrine contains a secret message that Lloyd can decode using his translucent reveal blade accessory, adding a puzzle element to the dragon battles.

Minifigures and Accessories

Four NINJAGO minifigures are included: ninja warriors Sora, Wyldfyre and Lloyd alongside the villainous Zarkt. Each comes with ninja weapon accessories to facilitate good versus evil battle scenarios across the dragon and shrine setting.

Designed for builders aged 7 and up, the set combines the appeal of a large, articulated dragon with story-driven play elements from the current NINJAGO television series.
