Thousands of years ago, the people of the planet Campbell decided to leave their planet and seek out new worlds to inhabit. One group, lead by the scientist Oreana, landed on Earth, but was delayed from their mission. In the early 21st century, Oreana's group reawakens and begins their plan to conquer the Earth. The only effective defense against the Campbellians' giant bio-mechanical slave beasts is the super-electromagnetic robot, Combattler V and its pilots. The entire series follows the then-standard Monster of the Week format, with the first season featuring Garuda sending various mecha to defeat Combattler V. His tactics range from brute force to cunningness and taking hostages. At one point he even duels Hyouma in a sword fight with their feet chained together. As the series moves on, his trust for Oreana lessens. Garuda eventually discovers that he is in fact a cyborg after chancing on a room containing numerous failed attempts at creating him. In the final episode of the first season, he defeats Oreana, and then duels Combattler V, which eventually leads to his defeat.
