Monster X Collection

The spaceship AAB-Gamma is dispatched from FAFC headquarters in Japan to make a landing on the planet Mars and investigate reports of UFOs in the area. As they near the red planet, they encounter a mysterious UFO that coats the ship's hull with unusual spores. Taking one of the specimens back to earth, it soon develops and grows into a giant chicken-lizard-alien monster that tramples Japan.

In 2008, all the world leaders are together at a G8 Summit meeting in Japan. A meteorite crashes into the heart of Sapporo and releases the monster Guilala. The monster rampages through Sapporo, leaving death and destruction in his wake.
