Aquaman

Arthur Curry lives a fairly normal life, being born on land as most humans are. This is until he discovers that he is not as human as previously thought. Arthur is only half-human, with the other half being Atlantean. This gives him a certain right to the Kingdom of Atlantis, which is underseas and currently being ruled by his evil half-brother. Orm, his half-brother, seeks to begin a destructive war between the undersea kingdoms and land. Being half-human and half-Atlantean, Arthur has connections to both the land and sea. Throughout the movie, Arthur must harness his full power and become Aquaman before the inevitable destruction of everything he knows.
