The LEGO Ninjago 71740 Jay's Electro Mech stages a dynamic battle from Ninjago TV series Season 4. This 106-piece set features Jay's posable Electro Mech, designed with jointed limbs that allow for various action poses as he confronts the villain Eyezor. Jay, equipped with his golden sword, pilots the mech, while Eyezor maneuvers his compact ninja car, accompanied by a small spider toy. A dedicated golden-sword display element complements the scene. The build incorporates a specialized Starter Brick chassis, facilitating quick construction of the mech, which enables fans to recreate specific combat scenarios from the Ninjago universe.
