Getter Robo
The Getter Robo is a super robot that utilizes Getter Rays as an energy source created by Dr. Saotome at the Saotome Institute. Originally built to harness the infinite power of the Getter Energy for space travel, the appearance of the Dinosaur Empire prompted Saotome to modify them for combat to stand a chance against their uprising.
Getter Robo is made up three jets that combine into one solitary super robot. Depending on the order of the jets, they form a different Getter. To align in the right formation, a monitor in the Getter Machines' cockpits are shown for the pilot to follow. The Getter Robo however can only be piloted by people of strong conditions both physically and mentally, otherwise the immense pressure and g-force caused by piloting a Getter machine will overwhelm the pilot.
A common technique used by the Getter Robo is the "Open Get" maneuver that causes the Getter Machines to detach from each other that allows the Getter not only to open up for additional formations but escape dangerous situations.
