An anatomical diagram of the Pirazaurus.

The Pirazaurus (ピラザウルス, Pirazaurusu) is a prehistoric creature with elements of piranhas and dinosaurs, native to South America. It is able to emit a deadly poison from its body, appearing as a powerful mist, strong enough to kill even a dinosaur in seconds.

There have been rumors of its existence since ancient times. A living Pirazaurus was discovered by Shocker, who analyzed it and used its body to graft with a modified human, resulting in the Shocker cyborg Pirazaurus. ^{[The Devil Wrestler, Pirazaurus]}
