Rodan Roar is a sound effect from TV shows, movies, and others.
Rodan's roar sounds like a mix between bird screeches and jets. Rodan's roar starts off like a shrieking, similar to birds. The roar then gets much deeper, and more screechy. His roar then ends in a long exhale. Rodan's roar was reused for many of the kaiju, such as the Heisei King Ghidorah and Battra.
