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.

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.
