Introduced in King of Braves GaoGaiGar FINAL, the original version of GaoGaiGar as designed by Cain of the Green Planet, based on the power of the G-Crystal from which the G-Stone is derived. Its necessary components - the five Genesic Machines and a copy of Galeon's original programming - were stored in a gigantic G-Crystal at the former location of the Trinary Solar System. Portions of its design (mechanical hair, distinctive "helmet") bear a resemblance to the design of Cyborg Guy in his Ultimate Armor. It is described as the strongest God of Destruction, the ultimate shape of courage. During The King of Kings ~GaoGaiGar Vs. Betterman~, Genesic Gaogaigar was corrupted by Triple Zero, and became known as the titular King of Kings. After being purified, GGG needed to pilot it while all of its components' A.I.s were still undergoing self-repair. GGG members piloted each Genesic Machine manually, and the mechanoid was renamed Final GaoGaiGar.
Genesic's design is distinctly different from its successors - in addition to having five GaoMachines rather than three, Genesic is given a much more streamlined design than GaoGaiGar or GaoFighGar, with flatly cylindrical forearms rather than the bulbous forearms of the others and a tail housing its option parts onboard rather than having them flown in seperately. It is also the only one which causes a change in Guy himself.
The orange "hair" is actually a connected series of power batteries, and when activated can give a temporary boost in power. Guy's Hyper Mode, for example, is powered by two strands of batteries. Genesic GaoGaiGar has significantly more than two strings of such canisters - each individual strand of hair is a line of dozens of batteries. Though only briefly shown (a little more than a second of footage near the end of the Goldion Crusher scene), the hair stiffens out when activated.
