Perseus Jackson

Perseus is more commonly known as Percy Jackson. He acts as the narrator in the Percy Jackson and the Olympians series, or PjO. (I highly recommend those books btw) Percy, in the fandom, is also know as Persassy Jackson for his sass. He is a demigod, which is basically half-mortal (human), half-Greek/Roman god/godess. His father is Poseidon, the Greek deity of the sea. He also appears in the Heroes of Olympus series, Magnus Chase series and Trials of Apollo series as well.

"Poseidon," said Chiron. "Earthshaker, Stormbringer, Father of Horses. Hail , Perseus Jackson, Son of the Sea God."
