Description

Mech and dragon as a villain duo

Ninjago sets regularly pit armed mechs and fantastical creatures against the ninja heroes. This set combines both: an armed mech built for close combat and a dragon-style rider that attacks from the air, together forming a versatile villain pairing for original Ninjago stories. Released in 2025 as part of the Ninjago range, the set picks one deliberately framed moment rather than attempting a full recreation. This page deliberately leaves out pricing or availability details, keeping the focus on the building experience itself.

Pieces, colours and minifigures

584 pieces across 231 unique parts split between the two builds, backed by 4 minifigures covering villains and ninja. Light bluish grey and white shape the mech's armour, while dark blue and dark bluish grey add the dragon's accents. Posable joints on both the mech and dragon allow for different combat stances. That works out to each unique part appearing about 2.5 times on average, a useful indicator of how many distinct build steps the set actually contains. Some of the listed colours appear in very small quantities but still contribute visibly to the finished look.

Two posable builds

Both the mech and the dragon come with their own moving elements, such as arms, claws or wings, that can be adjusted independently of one another. That opens up a range of duel scenarios without either model being locked into a single fixed pose. As with most sets in this size range, it helps to set aside enough time and a tidy surface for the many small pieces. Intermediate steps are easy to photograph or bag separately if the build needs to be paused and picked up again later.

Who it's for

This set suits Ninjago fans who enjoy building two functional vehicles instead of one, and anyone wanting to stage battle scenes with a full cast of minifigures. Every part and colour is listed in the parts list on this page. Anyone who already owns other sets from the same line will recognise the same build quality and attention to detail here. For a final buying decision, the parts list on this page is the most reliable reference, independent of product photos or marketing copy.
