About LEGO The Fire Knight Mech

Building this 996-piece mech offers an engaging construction challenge with intricate articulation and detailed armour plating. The posable design features movable joints throughout, allowing for dynamic action poses both on and off the display base.

The Fire Knight Mech stands 26 cm tall when positioned on its display base with spear extended. The model features a distinctive cape and detailed weaponry, designed to face off against the included sea monster with movable tentacles. The mech's chest compartment accommodates the included Kai minifigure, complete with blade accessory.

Interactive Features

The set can be removed from its scenic base for hands-on play, transforming from display piece to interactive model. The sea monster opponent features articulated tentacles that add movement to battle scenarios. A separate boat with fisherman minifigure provides additional storytelling elements.

The model is part of the NINJAGO Legends Monstrosity series, designed for older builders who appreciate detailed construction and display-worthy results. The combination of building complexity and play features makes this suitable for collectors and active play alike.
