The Invader Bot will explode, hurling the green fuel rod through the bars and out of reach. Then get Merlin to go pick up the Green Fuel. Then you have to take it to the Excalibur. Later Mordred fuses the Laser Lance, the Force Shield and the Ice Arrow to form the Green Fuel Orb, which would later be used to power his robot and subsequently, the Kingdom of Arturus.
