Godzilla vs. Biollante
The outline of Saegusa's character was present in Shinichiro Kobayashi's winning entry in the competition for a possible sequel story for "The Return of Godzilla" which would eventually become "Godzilla vs. Biollante", though the character was originally portrayed as a journalist investigating a scientist who accidentally created an amphibious rat monster called Deutalios. The character would have been led to the scientist's secret laboratory via psychic visions of talking flowers and subsequently discover that he had been splicing plant genes with those of his deceased daughter. It was ultimately director Kazuki Ōmori's decision to change Saegusa into a psychic.
