Godzilla cells left from his attack in the mid-1980's create a miniature arms race to secure them, involving Japan, US interests and Saradia. Eventually, due to conflicts, the samples are destroyed except one remaining in Japan at the Okouchi foundation. As the country and self-defense forces eye countermeasures should Godzilla appear again, including both ESP and Super-X2 programs, they begin to research Anti-Nuclear Energy Bacteria (ANEB). However, the ANEB requires a Godzilla cell, allowing an opportunity for doctor Genichiro Shiragami to become involved, a man devoted to his fallen daughter, who experiments on the cells in unpermitted ways... creating a new mutation in the process.
