Description

A walker instead of wheels

Unlike most Ninjago vehicles, which roll on wheels or tracks, this model stands and moves on two articulated legs. The open cockpit seats one minifigure and is flanked by posable arms that can grip or strike. Black and dark bluish grey form the frame, blue picks up Jay's signature colour, and pearl gold trims the armour plating and weapons for extra shine on display. The stance gives the set a distinct silhouette compared with the tanks and bikes that filled the same wave, and the wide-legged pose reads as sturdy and battle-ready on a shelf. Collectors with several mechs from the Rebooted era tend to appreciate this clear split between the base colours and the gold accents, since it keeps the set easy to pick out even from a distance.

133 unique parts in a compact build

With 133 unique elements across 386 pieces, the set packs in a fair amount of variety for its size. Hinges at the hips, knees and shoulders keep the mech poseable without compromising stability once built, allowing several stances from a fighting crouch to a standing guard pose. The parts list on this page is a useful reference for anyone comparing hinge pieces, specialised moulds or colour runs against other 2015 Ninjago sets, and the gold-finished elements work well as accent pieces in other builds too. The mix of standard bricks and more technical connecting elements also keeps the build process varied without tipping into overly complex territory, which suits confident young builders well.

Four minifigures for storytelling

Four minifigures come with Jay Walker One, which is generous for a set of this size and opens up scenes with more than one pilot against a single rival. That makes it a solid pick for open-ended play as well as display, and a good base for larger duel scenes alongside other Ninjago sets from the same season. The full parts list on this page breaks down every element individually, so missing pieces are easy to reorder and figures or accessories can be pulled out for other builds. That also makes it straightforward to combine the walker with other 2015 Ninjago vehicles for bigger scenes involving several mechs at once.
