Correct me if I'm wrong....

Yes and No. toi see, in Percy Jackson Annabeth called them 'The Gray Sisters' As toi mentioned, they shared one eye and one thooth. Rick Riordan and Disney got their inspiration from the ancient Greek mythology, plus specifically the Perseus myth. Perseus was send on a quest to defeat the gorgon Medusa. To find her location, he had to go to the Graeae, the three old ladies with the eye and thooth. When they refused to answer his question, he took the eye and thooth as ransom so they had to answer him. Now, to come back at your question: Yes they are pictured as Fates from the cartoon Hercules, but in reality the Fates and the Graeae are two completly different kind of creatures.

no,no,no,no,no,there the gray sisters,they do share an eye,but,they are nothing like the fates,
also,dont belive any thing Disney a dit in the movie Hercules,he was already a demigod,he didnt
go that way becus of a potion,its al fake Disney
