On the brink of an alien invasion, the enigmatic billionaire known as Sandman gathers the world's leaders at his castle to unveil Earth's last hope: a gravity powered god of circuits and steel called Gravion! From that first prototype eventually comes a squadron of giant robots piloted by pneumatic cuties as beautiful as they are deadly. This super-collection combines Gravion and Gravion Zwei.
