Godzilla vs. Destoroyah
Doctor Ijuin had been working on a new experiment by the time of Godzilla's meltdown, and developed a chemical that he claimed could be used in many fields, dubbing it as 'Micro-oxygen'. Emiko Yamane learned of this after he broadcasted his discovery on television, and told Kenichi Yamane and Yukari Yamane to tell the doctor to stop the research, as his chemical was dangerously similar to the Micro-oxygen that was used to kill the original Godzilla in 1954. However, Kenichi and Yukari instead ask the Doctor to develop another ]Oxygen Destroyer, knowing that it might be their only chance to destroy Godzilla before he destroys Japan. However, upon learning of the fact that Destoroyah came about as a result of the Oxygen Destroyer in 1954, the doctor shelves the research for good.
