But this great invention of Rottwang's had not gone unnoticed. Alien spies from the Marphet Galaxy were watching Rottwang's progress with great interest. It was their plan to steal the manmoth robot and use it for their own insidious purpose: To conquer the Earth!!!
Finally, the time came when the robot was completed. As Rottwang and his children celebrated, the Aliens struck, attacking Rottwang's laboratory with their giant mutate Air Dragon.
But, Rottwang, having been aware of the Aliens interest in his invention for some time, was not caught off guard. Managing to activate Big Crush in time, a titanic battle ensued. The power
of Big Crush proved a match for the alien Air Dragon, and both it and it's alien master's were repelled.
