The King of Braves - GaoGaiGar 32

On a winter night, a mysterious mechanical lion flew before a married couple carrying a mysterious baby. As they took the baby in, the lion left them in confusion. About 7 years later, the space shuttle Spirits, in which high school astronaut Guy Shishioh is a passenger, collides with an unknown object bound to Earth. Despite being mortally wounded, he is rescued by the same mysterious lion and returns to Earth. He holds a mysterious green jewel in his hand as Leo Shishioh uses it to revive Guy into a cyborg. Two years later, in 2005, the mysterious baby under the care of the Amami couple, now named Mamoru, is living his life normally. This is until the mysterious group known as Zonders begins their invasion of Earth. As a response, the Earth Defense Brigade Gutsy Geoid Guard, or GGG, was organized to fight against the Zonders. In an attack by the Zonders, the mysterious boy encountered Guy, now a member of GGG. Equipped with the green jewel G-Stone, he becomes the pilot of the lion robot that saved him. Named Galeon, he fuses with it alongside 3 assist vehicles created by GGG to become the giant robot GaoGaiGar. After the battle against one of the Zonders, GGG discovered that Mamoru could purify people who became Zonders and wondered about his origins and how it was linked to the appearance of the Zonders.
