King of Braves GaoGaiGar

Synopsis

In 2005, alien monsters called the Zonders emerge from beneath the Earth and attack Tokyo. The only defense against them is the secret organization known as the Gutsy Geoid Guard, or 3G, along with their ultimate weapon: the giant mecha GaoGaiGar. Its pilot, Guy Shishio, was an astronaut who barely survived death two years earlier when the Zonders first struck. His rescue came from a mysterious robotic lion named Galeon, which pulled him from his burning spacecraft. Guy's father, Leo, used Galeon's technology to turn his critically wounded son into a cyborg, hoping he could fight the aliens when they returned. With Galeon now serving as its core, GaoGaiGar battles to protect the planet. Assisting Guy are a squad of transforming robots and a young boy named Mamoru, who has the ability to purify the Zonders' cores and seems to share a mysterious connection with the elusive Galeon.
