Well, Percy could use his water powers in really cool ways during Avengers' battles. For example, he might create huge tidal waves to stop enemy attacks. And he could teach the Avengers some new combat moves that he learned from Camp Half - Blood. Maybe he'd also introduce them to Greek mythology monsters and how to fight them.
The story could start with Percy being found by the Avengers in a strange situation, like after a battle with a Greek - inspired villain. They take him in not fully understanding his powers at first. As time goes on, Percy helps them understand the world of Greek gods and demigods. He might even introduce them to his sword, Riptide, which could be a fascinating object for the Avengers to study. His presence could also lead to new storylines involving ancient Greek prophecies and how they might affect the Avengers' world.
