The Golden Mech was originally created by the First Spinjitzu Master during his battle with the Overlord. Charged with the Power of the Golden Dragon, it was designed to be the ultimate weapon against Darkness. After the lands of the NINJAGO world were split in two by the Golden Sword, the First Spinjitzu Master stored the mech in the heart of the Temple of Light, where he believed it would be safe. Centuries later, Lloyd recovered the Golden Mech before the final battle against the Overlord. When the ninja placed their elemental blades in the pillars around the center of the temple, the Golden Mech arose from below. The Golden Mech was damaged during the battle and never seen since.
