Minifigures 6
Description
A mech built for one ninja
Titan Mechs are a recurring format within Ninjago, where a single ninja gets a large, poseable battle robot built in their own elemental colour. Here, that's Jay, the ninja of lightning, and the mech is coloured blue to match, making it instantly distinct from the mechs built for other characters. For collectors lining up several Titan Mechs together, that colour system creates a clear, easy-to-read set of matching, well-coordinated models that work well as a team.
798 pieces behind a working mech
Blue, black, white and light bluish grey echo Jay's familiar look from the show, so the finished mech is easy to identify at a glance. The 798 pieces build a poseable robot body with joints at the arms and legs, plus weapons and accessories that attach to the mech itself. That adds play value beyond looks alone, since the finished model can be posed in different positions and used in play battles rather than just standing on a shelf.
Six minifigures for full scenes
The set includes 6 minifigures, noticeably more than many sets of a similar size, which works well for building out battle scenes between the mech and several opponents at once. That combination of one large model and multiple figures makes the set more versatile than a typical vehicle set with only one or two figures. Anyone who already owns other Ninjago sets can also mix these figures in with existing characters from other stories and expand the cast further.
247 parts in detail
The model uses 247 unique parts in total, all listed in the parts list on this page. That's worth checking if you're after specific joint pieces, weapons or blue specialist bricks, whether for your own modifications or to add to other mech builds. It also makes it easy to judge which parts are useful beyond the finished mech itself before you even open the box or start building.
