- Badass Decay: Mu Agent 23. Once a considerable threat, now a henchman doing nothing against the Atragon.
- Crowning Music of Awesome: Akira Ifukube's talent is shown again.
- Special Effects Failure: The miniature effects in this film aren't quite up to the usual Toho standards, especially the ones that involve water. It's often very obvious that the Atragon is just a small model on strings and that Manda is just a puppet.
