MechaShoulder (メカショルダー Mekashirudā?, 1): A spider-like Battle Machineman with massive shoulders and hidden weapons such as an electrical laser under its faceplate that was deployed to deal with Spielban and Diana. During the battle Spielban managed to blast off the robot's arms, but the ring on its back remained and was used to bind Spielban. Gathering the strength he had left, Spielban broke free and destroyed MechaShoulder with his Arc Impulse.
