The trailer opens with a majestic underwater shot of Atlantis, its towering structures glowing softly in the deep ocean. The serene scene quickly shifts to chaos as massive tidal waves crash over coastal cities, and dark storm clouds gather ominously above. We hear Arthur Curry’s voiceover, calm but resolute: “I’ve fought wars and faced monsters, but this… this is different.”
Cut to Arthur, now fully embracing his role as the King of Atlantis, sitting on his throne in the grand council chamber. Beside him is Mera, her expression grave as she reads a scroll detailing a new threat: the return of Atlan, the first King of Atlantis, resurrected by a dark sorceress named Nereida. Atlan, furious over the state of his once-glorious kingdom and the mingling of humans and Atlanteans, seeks to reclaim his throne and return Atlantis to its former glory by any means necessary.
The trailer intensifies with quick cuts of Atlan (played by a new actor) wielding the powerful Trident of the Depths, unleashing devastating whirlpools and summoning ancient sea creatures to wreak havoc. He declares, “I am the true King, and I will purge Atlantis of the unworthy.” We see Arthur and Mera rallying their allies, including Orm, now a begrudging ally, and Vulko, who warns that Atlan’s power is beyond anything they’ve faced before.
A montage follows: Arthur battling Atlan in the ruins of an ancient temple, Mera conjuring powerful water blasts against a horde of enemy warriors, and Orm leading a desperate charge against Atlan’s forces. The stakes rise as Nereida reveals her true plan: using Atlan’s power to raise a mythical island called Lemuria from the ocean depths, an act that would devastate the surface world and plunge it into chaos.
The trailer’s climax features an epic underwater battle. Arthur and Atlan clash in a high-stakes duel, their tridents colliding in a burst of energy. As the ocean churns around them, Arthur’s voice rings out: “I am the protector of two worlds, and I will not let them fall.” The final shot shows Arthur standing on a cliff overlooking the stormy sea, his trident raised as the screen fades to black.
