It could be a demigod who was once a hero but became corrupted by power. Maybe they were overlooked for some big honor at Camp Half - Blood and now they seek revenge on Percy and the other heroes. This character could have powers similar to Percy's but use them for evil, like causing tsunamis to destroy coastal cities instead of protecting them.
A new race of creatures could be the antagonist. For example, a group of shadow - like beings that can possess demigods and turn them against their friends. They could be from a realm that was previously unknown, and they target Percy specifically because he's the most powerful demigod around. Their goal might be to take over the mortal world and the world of the gods by using the demigods as their pawns.
The antagonist could be a former god who was banished long ago and now has returned with a vendetta against the current Olympian gods. They might see Percy as a tool to use against the gods, either by turning him to their side or by eliminating him to weaken the gods' forces. This former god could have unique and terrifying powers that Percy and his friends have never faced before.
