The Griffin is a mythological creature resembling a cross between a big cat and a bird that appeared in the film Hercules.
In the film, Hades sends him, the Minotaur, and Stheno to gang up on Hercules, but all 3 of them were defeated by a punch each from Hercules in less than a few seconds. The Griffin was between the Minotaur and Stheo when they landed in a pile.
- In the original storyboard for Zero to Hero, the Griffin and Stheno (who in the original storyboard was fought instead of Ceto), were replaced by a huge green fish with a unicorn horn and a giant lobster who helped the Minotaur fight Hercules.
- This griffin resembles a cross between a panther and a raven, similar to the ones described in The Heroes of Olympus book, The Son of Neptune.
