About LEGO Kai's Dragon Mech Battle Pack
Kai's dragon mech features 360-degree rotating torso, posable legs and large wings that create an imposing battle-ready figure. The mech includes claw hands and a cockpit designed to hold a minifigure, allowing for dynamic combat scenarios from the NINJAGO Dragons Rising TV series.
This 85-piece set includes three minifigures: Kai, Sora, and an Earth Monster villain. Each character comes equipped with weapons - Kai and Sora each carry two swords, while the Earth Monster has integrated claw hands. The combination provides everything needed for good versus evil battle scenarios.
Build and Display
The completed dragon mech stands over 9 cm high and offers multiple points of articulation for posing and play. The design balances sturdy construction with the flexibility needed for action sequences, making it suitable for both display and active play sessions.
Designed for ages 6 and up, this set connects to the broader NINJAGO universe and can be combined with other sets from the theme to expand battle scenarios and storylines.
