Following the chaos of Aquaman and the Lost Kingdom, speculation swells about a third installment — one that could pit Jason Momoa’s Arthur Curry against a younger, ambitious rival with ties to Atlantis’ forgotten past. Industry whispers suggest Timothée Chalamet might be eyed to play a mysterious Atlantean exile, 𝐛𝐨𝐫𝐧 of royal blood but cast out long ago, now returning to reclaim what he believes is rightfully his: the throne.

Fan theories hint that Aquaman 3 could explore the cracks in Arthur’s rule as King of Atlantis — with political unrest, rebellion in the outer colonies, and doubts about surface alliances. The arrival of the exiled prince could spark a civil war, with ancient magic and high-tech warfare colliding in massive underwater battles. Some even speculate that the film could tie in with the larger DC multiverse shake-up, introducing conflicting timelines or legacy disputes over Atlantis’ true heir.

Whether the clash is one of bloodlines or ideologies, Aquaman 3 has the potential to become the most emotionally charged and visually grand of the trilogy — a Shakespearean struggle beneath the sea. With the ocean itself choosing sides, the question becomes not just who will win… but who is worthy to rule the deep.
