The X from Outer Space

“Mankind threatened by a deadly nucleus from the vast void of space”

Capt. Sano (Shunya Wazaki) wants to land the spaceship AAB-Gamma on Mars and find out what is behind the UFO reports that sent the crew out from FAFC headquarters in Japan. Kazui Nihonmatsu follows the mission as a strange craft passes close and leaves spores caked across the ship's hull. One specimen gets carried back to Earth, where it grows into a chicken-lizard-alien creature that tramples Japan.
