The tides are rising again as the highly anticipated Aquaman 3 (2025) makes waves in the DC Universe, and fans are eagerly diving into the first trailer for the upcoming film. After the global success of the previous two installments, Aquaman 3 promises to explore deeper into the undersea kingdom of Atlantis, while setting up a new era for Arthur Curry, aka Aquaman. With stunning visuals, new threats, and a deeper dive into the lore of Atlantis, this third chapter in the Aquaman saga is shaping up to be a major blockbuster for 2025.
The first trailer for Aquaman 3 introduces an all-new set of challenges for Arthur Curry. In the wake of the events of Aquaman (2018) and Aquaman and the Lost Kingdom (2022), the world’s oceans are in a fragile state. While Atlantis has been stabilized under Arthur’s leadership, a new, even more powerful threat emerges from the depths—a faction of ancient ocean-dwellers known as the Tritonites.’
These ancient beings, long-forgotten by the surface world, have now risen to challenge Aquaman’s reign. As hinted in the trailer, the Tritonites are a race with advanced technology and devastating elemental powers tied to the very forces of the ocean itself—powers that could easily wipe out both Atlantis and the surface world. Their leader, King Nereus, played by Michael Fassbender, is a fierce and ruthless ruler bent on restoring the oceans to their “pure” state by destroying human civilization, which he believes is polluting the planet’s waters.
The trailer teases massive underwater battles, with Aquaman facing off against the Tritonites in visually stunning sequences that make full use of the ocean’s vast, uncharted depths. The stakes are higher than ever as Arthur Curry must defend his kingdom and protect both Atlantis and the surface world from total annihilation.
Fans of the DC Extended Universe (DCEU) will be thrilled to see Jason Momoa return in his iconic role as Arthur Curry / Aquaman. Momoa’s portrayal of the reluctant king and the fierce protector of Atlantis has become a fan favorite, and the new trailer offers a tantalizing look at how Aquaman has evolved.
In Aquaman 3, Arthur is not just a hero—he’s a king struggling with the immense weight of leadership. His relationship with Atlantis is more complicated than ever, and the film delves into his internal conflict between his duty to his people and his desire to protect the world above the surface. Momoa brings his signature blend of charisma, physicality, and humor to the role, while also giving Aquaman a more mature, introspective side as he grapples with his growing responsibilities.
There are also glimpses of Aquaman’s partnership with Mera (played by Amber Heard), his fierce and loyal ally, who continues to be a key figure in his fight against the rising threats to Atlantis. Their dynamic has matured, and their relationship will be tested as they face challenges that go beyond mere physical combat.
One of the biggest draws of Aquaman 3 is the opportunity to explore more of the vast, uncharted world beneath the waves. The trailer offers a glimpse of The Trench, a terrifying and hostile region of the ocean where dangerous sea creatures lurk, as well as other locations in Atlantis that were not explored in the previous films.
