The body of Big Crush was constructed of a new metal developed by Rottwang himself. This metal was called "Titanite", and was the strongest metal known to man. It was rumored to be strong enough to weather an atomic blast.
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.
The Alien's were defeated, but at a terrible cost: Rottwang's son, Aaron, was mortally wounded in the resulting conflict. Grief stricken, Rottwang managed to transfer Aaron's brainwaves into Big Crush's computer memory banks. For all intents and purposes, Big Crush was Aaron!
And so, the three stood united: Rottwang, Julia and Aaron/Big Crush stood ready to defend the Earth against all invaders! Quickly, word spread throughout the Galaxy:
