Description

Two builds, one confrontation

Instead of a single model, this set delivers a mech and a dragon designed to face off against each other, which is a familiar format for Ninjago sets and gives a battle scene straight out of the box rather than a model meant just for display. Black and dark bluish grey dominate the mech, while green and pearl gold pick out the dragon, giving the two builds distinct identities despite sharing a parts pool. Both models stand on their own, so the confrontation can be staged from any angle on a shelf or a play mat. That flexibility also makes the pair easy to photograph from different sides.

Jay takes the controls

Jay, a recognisable Ninjago character, comes as one of the two minifigures and can be placed in the mech or set against the dragon depending on how the scene is played out. Both figures move freely between the two builds rather than being fixed in place, which keeps the confrontation open-ended. That link to a known character gives the set an edge for anyone already following the Ninjago story, even without a narrative printed on the box. Owners of other Ninjago minifigures can easily swap in extra characters for a bigger battle. That flexibility suits anyone who enjoys restaging scenes rather than a fixed layout.

Compact builds, clear colours

49 unique part types spread across 107 pieces split naturally into two shorter builds rather than one long one, which suits a quicker building session or building the mech and dragon on separate occasions. The black, green, grey and gold palette keeps the two models easy to tell apart at a glance. The full parts list on this page covers all 49 shapes by colour and quantity for anyone after specific pieces or comparing the set with others in the Ninjago range. Building the two models on separate days also works well for anyone fitting the set into shorter windows of free time.
