Hugh Jackman is angry in Deadpool & Wolverine next to the dead celestial's emerging head from Eternals

While the MCU’s Wolverine hasn’t been introduced yet, the latest reveal from Captain America: Brave New World suggests an Adamantium-enhanced hero has existed in the multiverse for 10 years. The first trailer for Brave New World featured a surprising shot of Sam Wilson’s Captain America flying past Tiamut, the dead Celestial emerging from the Earth since the end of Eternals. The Celestial’s presence has not been addressed since, but Captain America 4 will be the first to properly show how the world reacts to this intergalactic being.

According to trailer footage from Marvel’s 2024 San Diego Comic Con Hall H Panel which Screen Rant attended, Harrison Ford’s President Thunderbolt Ross reveals how the MCU will introduce Adamantium to the universe, as the character states the world has been fighting over the Celestial’s resources, which includes Adamantium. Adamantium is a new element in the MCU, but its attachment to Celestials significantly changes its origins from Marvel Comics. It also implies that Wolverine won’t be the first MCU character with Adamantium, as another character could possess the element based on Adamantium’s new beginnings.

Captain America: Brave New World’s Adamantium Reveal Changes Star-Lord’s Origin

Captain America 4‘s Adamantium change could have implications for Peter Quill, a.k.a. Star-Lord. In Guardians of the Galaxy Vol. 2, Peter’s lineage is revealed when he meets his father, Ego. Ego is a living planet that can take the form of a human being or any shape he wants. He spent thousands of years traveling to different planets and having children, hoping one would help his dream of universal expansion. He is a character of limitless power, and some of those abilities were passed down to Peter, who inherited his Celestial powers.

Ego may not look like his Celestial brethren, but he has many of the same abilities as the others. If the other Celestials are made out of Adamantium, it would make sense that Ego has the same element and transferred it to Peter. Peter did have the same powers as his father for a short while, and those powers may have been amplified by the Adamantium that flowed through him. It would also make him the first Adamantium-enhanced MCU character, well before Wolverine joined the universe.

Why The MCU’s Adamantium Changes Make Sense For Its Overall Story (& Star-Lord’s Powers)

Adamantium’s change from Marvel Comics fits the MCU’s narrative after seeing how countries reacted to Vibranium. As seen in Black Panther: Wakanda Forever, many countries wanted to steal Wakanda’s Vibranium once it was revealed to the world. With a dead Celestial sticking out of Earth, it makes perfect sense for countries to see what elements or resources they can harvest from it. It can also introduce Adamantium as a legitimate reason for countries to feud with one another while establishing a powerful new element for the MCU.

For Star-Lord, it’s unclear if he still has any Adamantium. Once the Guardians of the Galaxy killed Ego, it severed Peter’s connection to his father, removing his Celestial powers. Since he is seemingly a regular human now, he may not be comprised of the Adamantium that other Celestials possess. It will be intriguing to see how Captain America: Brave New World establishes this element, and what it means for the MCU’s future.

Fortunately, the MCU can easily get out of Star-Lord’s Adamantium connection. Since he became a regular human after Ego’s death, Marvel can say that he doesn’t have Adamantium anymore or the studio can completely ignore it. The element has never been an important part of Peter’s story, and most audiences won’t notice if Marvel never addresses it. It’s mainly a setup for the MCU’s Wolverine, and the other X-Men characters influenced by Adamantium. However, Adamantium’s change from the comics suggests it could be present in so many things throughout the universe.

If the element becomes an important part of the MCU’s future, then it could be worth looking into how it affects Star-Lord. Since Star-Lord is now a solo hero, it may be interesting to see him explore his celestial ancestry and how he fits into the galaxy. Adamantium’s connection to celestials means it has been around for billions and billions of years, and it would be intriguing to see how the element has impacted history and other planets in the universe.

The MCU’s Adamantium Plotline Could Mean Star-Lord Returns Sooner Than Expected

Guardians of the Galaxy Vol. 3 ended with the statement, “The Legendary Star-Lord will return.” It’s unclear when that will be, but it could be sooner than expected if he has a connection to Adamantium. Star-Lord is now on Earth with his grandfather at a time when countries are fighting over Adamantium mined from a celestial. Since Peter is one of the few humans who knows about celestials, his involvement could be crucial in helping the world learn more about celestials and their abilities, especially after Arishem the Judge exposed himself.

He would also learn about his Adamantium connection, leading to him wondering about his own celestial makeup and if there is anything left. While he’s expected to return to the MCU at some point, it’s unconfirmed whether it’ll be in a solo project or as a member of another team. However, the title of “Legendary Star-Lord” suggests it will be solo as it connects to his lone comic book adventures, so Adamantium’s introduction could be an exciting way to kickstart his journey. He likely won’t appear in Captain America: Brave New World, but this does open the door for future appearances.
