Biollante first appeared in the 1989 Toho film Godzilla vs. Biollante as a giant mutated plant kaiju created from Godzilla's genetic material and a rose, facing Godzilla in a battle between nature and nuclear power. The character later appeared in Godzilla video games and fan media, keeping its unusual design and guttural roar familiar to kaiju fans. Online, short clips of its roar are shared by Godzilla enthusiasts and reused in edits, animations and memes that need an instantly recognisable monster sound, which has kept this lesser-known kaiju in circulation long after its film debut.
