Aphros: "We have trained all the famous mer-heroes! Name a mer-hero, and we have trained him or her!"
Leo: "Oh, sure. Like…um, the Little Mermaid?"
Aphros: "Who? No! Like Triton, Glaucus, Weissmuller, and Bill!

"Oh." Leo had no idea who any of those people were. "You trained Bill? Impressive."

Aphros and Leo, talking about Bill

Bill is a well-renowned hero of Camp Fish-Blood and a merperson.

History

Bill was trained in combat by Bythos and in music and poetry by Aphros. He is considered by Aphros to be one of the greatest Mer-Heroes that he has ever trained.

The Heroes of Olympus

The Mark of Athena

Bill is mentioned by Aphros and Bythos as one of the many mer-heroes trained at Camp Fish-Blood, despite Leo Valdez not knowing any of them. However, Leo fakes a surprised expression when he hears about Bill. After Aphros and Bythos are done questioning Leo, Hazel Levesque, and Frank Zhang, they agree to send a group of mer-people off to Atlanta on a quest to rescue all the imprisoned sea creatures there, with Bythos suggesting Bill go on the quest and Aphros agreeing. It is later said that the creatures being held by Phorcys at the Georgia Aquarium were freed.
