Altman originally designed a cosmonaut wearing a suit similar to western armor, but under the request of playwright Tetsuo Kinj? (1938-1976), he wanted to be a cosmonaut with a handsome posture and made a new design. Later, Narita Hiroshi redesigned Altman according to the idea that the opposite of chaos is order.

If the monster with complex shapes designed by combining various elements is chaotic, as the opposite hero, it must be an order with simple and pure beauty. Under this concept, the redesigned Altman head is extremely simplified, without any unnecessary decoration. With reference to Maitreya, the mouth shape was designed with a smile.
