Baragon was created by Toho and first appeared in Frankenstein vs. Baragon in 1965, where the burrowing kaiju emerged from underground to fight Frankenstein's monster. The character later returned in Destroy All Monsters and gained wider recognition in Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack in 2001. As kaiju clips spread through fan edits, forums and soundboards, Baragon's distinctive roar became a reusable monster sound, separate from the films, for creators who want an authentic Showa-era creature voice without using Godzilla himself.
