MCU fans have been understandably frustrated by the apparent lack of connectivity during Phase 4, but one big unresolved plot thread looks set to be key to Captain America: New World Order in the upcoming fifth Phase of storytelling.
At the end of Eternals, Sersi used her powers to transform the emerging Celestial, Tiamut, into marble, leaving a massive alien God sticking out of the Indian Ocean. That's yet to be addressed by Marvel Studios, with hopes that Namor might bring it up in Black Panther: Wakanda Forever quickly dashed last month.
A couple of days ago, a rumour started doing the rounds that Thunderbolts will see the team head to the Celestial's resting place, with the island now known as Genosha. Those of you familiar with the X-Men comic books will remember that as a location inhabited exclusively by mutants that Magneto ruled over.
Since then, it's been claimed that this is, in fact, "Tiamut Island," with the spotlight actually put on the Celestial in Captain America: New World Order. As expected, it seems the world's governments will realise that they can make use of Tiamut's remains, hence why this is supposedly where Adamantium will be introduced.
Yes, the indestructible metal that coats Wolverine's claws is going to originate from Tiamut, with various countries - including the U.S. - going to war in an effort to lay claim to a resource that's even more valuable than the Vibranium Wakanda has deprived them of. Unsurprisingly, Harrison Ford's President Ross will be among those looking to take control of the island.
We'd bet on Tiamut Island also factoring into Thunderbolts given how close to the next Captain America movie that arrives in theaters.
As for the X-Men, it seems Marvel Studios will take a slow-burn approach to introducing the mutants, though Phase 5 could start setting the stage for them to one day call Tiamut Island/Genosha/Krakoa(?) home.
Captain America: New World Order is set to be released on May 3, 2024, while Thunderbolts follows on July 26, 2024.
