Reigon was a giant manta ray.
Reigon and his unnamed giant iguana opponent were scrapped along with their film and replaced with Gappa, the Triphibian Monster.
- Reigon was the fourth monster that Nikkatsu planned were going to star in their own film before they settled on making Gappa, after Gigant, Arkitius, and Momonra.
