Asian Drama

Some 400,000,000 years after an advanced human civilization was destroyed by aliens, 12 direct descendants of the civilization's warriors (called "Sazers") have their powers awakened and form four tribes: Flame, Wind, Earth and Water. Each Sazer is based on a Zodiac sign represented in an animal totem or spirit representation. At first, they wage war on each other, but after learning the truth of their ancestry and their reason for awakening, the Gransazer tribes unite to protect Earth from the Warp Monarch, an alliance of various alien species, from once again extinguishing all life on the planet.

The series featured many firsts for the franchise, including the start of the story in a movie rather than the series proper. Ultraman Cosmos: The First Contact was the prequel to the series and took place ten years before episode 1. In it, 9-year-old Musashi Haruno encounters the being of light, Ultraman Cosmos, and befriends him as the two confront a threat to Earth.

Ten years later, Musashi, now 19 and a member of Team EYES, once again encounters the being of light from his childhood. The dark being Chaos Header has appeared and is corrupting the monsters of Earth, making them become ravenous and violent creatures that threaten humanity. Through Musashi's will to see the beasts and humans live in peace, Cosmos grants him a new power that will allow him to heal the corrupted creatures.
