Benkei Kuruma is the successor to the heavy duty and marine formation of the Getter Robo and its other models after Musashi's death. Like Musashi he continued the trend where a large framed person piloted the third formation. Some series have not included Benkei in their lineup either due to his character being fused with Musashi and Musashi never dying in the first place.
