There are lots of similarities between Jason and Percy. They have both fought with Titan Lords, (Kronos and Krios) They are both named after famous mythological heroes, and they are both seen as leaders at both of thier camps. (well... not Jason anymore) Personally I think just as there are Greek/Roman forms of the gods, there are also Greek /Roman forms of demigods. Annabeth and Reyna are a lot alike, so are Grover and Don, Lupa and Chiron, and... I don't know... Vitellius and Mr. D maybe?
