Ariel is the daughter of Triton, who is the son of Poseidon. Poseidon is the brother of Zeus, who is father to Hercules. That would mean Ariel and Hercules are related.

Okay, that one, I knew thanks to my love of Percy Jackson and Greek myths, but to those of you who didn't know, thank PATRICK_STAR_HI for it!
