Godzilla vs. Biollante
Toho rebooted the series in 1984 with "The Return of Godzilla", starting the second era of "Godzilla" films, known as the "Heisei" series. "The Return of Godzilla" serves as a direct sequel to the original 1954 film and ignores the subsequent events of the Showa era. "The Return of Godzilla" was released in 1984, five years before the new Emperor, but is considered part of this era, as it is a direct predecessor to "Godzilla vs. Biollante" (1989), which came out in the first year of the new Emperor's reign.
