Kres Ultraman

A hundred-year war erupted across the universe. The Lurlians and their allies sought to carve up the entire cosmos. While patrolling the solar system, Kres detected a Lurlian warship heading for Earth. Kres destroyed it with Ultra Dynamite, then crash-landed on Earth alongside the Lurlians. After that, biological weapons buried beneath the planet awoke, and aliens from across the universe began arriving on Earth. Ultraman and the Defense Force fought back against invasion after invasion.
