The Siren from Atlantis

The Avengers are hanging out together on the deck of the facility when suddenly a girl climbs from the water. She's covered in bruises and wounds and seems to have lost her voice as well. They discover a world that they thought was just a myth as they try to help the girl resolve the war of the oceans. Will they succeed in their new mission? Or will the fact that one of them is especially intrigued by the girl, distract them from their cause?
