With Captain America: Brave New World, or, Adamantium will make its way into the Marvel Cinematic Universe, setting the stage for Wolverine’s origin and future storylines.
The film will depict Adamantium as a newly discovered resource originating from the dead Celestial seen in Eternals. This discovery will lead to a geopolitical conflict, setting the stage for its role in Project X and Wolverine’s transformation.
Captain America 4 director Julius Onah confirmed in an interview with ScreenRant that Adamantium will “eventually be a part of Project X” and will “eventually be a part of the story of Wolverine.” The film establishes a new origin for Adamantium, revealing that it comes from the dead Celestial seen in Eternals.
President Thunderbolt Ross describes this discovery as the “discovery of the millennium,” triggering global competition for the powerful metal.
Onah elaborated, stating, “Adamantium is much more durable. Adamantium is not like Vibranium, which can absorb kinetic energy.” He emphasized the global stakes of this resource, adding, “Adamantium now becomes this resource that could change the world in a way that’s very different because Vibranium is something that is really under the purview of the Wakandans.
