. . . . . . "Gekko served as a secondary antagonist in the Kaguya Arc of the Yaiba series. He was at first a part of Kaguya\u2019s invasion force on Earth a thousand years ago. However, he was defeated by the original Ryuujin and lost his right eye. During Kaguya\u2019s 1000-year slumber on the Moon after her defeat at the hand of Ryuujin, Gekko created havoc on the Moon but was captured and imprisoned. A thousand year later, Kaguya launched another invasion on Earth, facing Yaiba, who inherited Ryuujin\u2019s powers. After discovering that she can return to her true primal form by sucking the extract of Sayaka, Yaiba\u2019s friend, Kaguya had Gekko freed from prison and ordered him to capture Sayaka, promising him the entire Japan. Gekko raided the Mine residence to capture Sayaka, but despite proving superior to other Moon rabbits, Gekko was overwhelmed by Yaiba\u2019s Ryuujin-ken. He then raided Area 666 in Kaguya\u2019s base, taking the terrifying Demon King Sword. With this sword, Gekko proved too powerful for Yaiba and later even the combined powers of Yaiba and Onimaru. It took the duo a newly-developed technique, the Furaijinha, to defeat him. Gekko later fused with other Moon Rabbits into a being that in turn fused with True Form Kaguya into a being that in turn fused with Earth. Kaguya and all her henchmen, Gekko included, were eventually sealed into the planet\u2019s core by Yaiba. After the event of the Yamata no Orochi, Kaguya and all her underlings returned to the Moon, hoping to restore it back to a beautiful planet."@en .
