Following his 13 year Getter Ray-induced excursion across space and time, Ryoma awakens in the abandoned unit, discarded on a lunar base which had been deserted following the Moon Wars. After extensive modifications and repairs, Ryoma flies this machine back down to earth, where it acquires its signature black color scheme after the original paint job burned-up due to atmospheric re-entry.
Although possessing the same overall body shape of a Getter-1 Unit, the Black Getter had several differences besides the aforementioned new black color. It displayed a redesigned knee armor, lacked the antennae usually seen under the ears, came equipped with a mouth guard acting as the hatch to the cockpit, and possessed pupils in its eyes, similar to those seen on Shin Getter Robo. All these new features gave the Black Getter an intimidating appearance, and gave off the impression that it was alive. [Source: wikia]
