- Executive Meddling: The whole series is a positive example. Toei approached Go Nagai about adapting his horror manga Mao Dante into an anime, but wanted a more human-looking main character. Thus Devilman was born.
- Hey, It's That Voice!: Dr. Wily!? Why are you a turtle, and more importantly, why are you eating people!?
- Combined with Relationship Voice Actor, we have what appears to be a cast reunion from another Dynamic Pro-related series, Mazinkaiser SKL, as the 3 leads there play the 3 leads here for the Cross Over with Cyborg 009. Case in point:
- Ken Kaido is Akira Fudo.
- Ryo Magami is Ryo Asuka.
- Tsubasa Yuki is Miki Makimura.
