That's because Captain America: Brave New World brings adamantium into the fold. The substance shows up in the body of the Celestial that emerged from the Indian Ocean in Eternals. Now, it's the cause of international conflict, as major world powers try to control the world's only known adamantium supply.

Captain America: Brave New World isn’t the best or the worst MCU film. It has some genuinely fun action scenes. There’s a good political thriller buried in the overstuffed plot. Anthony Mackie did a really great job as Captain America, and as someone who is generally not a huge fan of Mackie, I’m happy to report that he really grew on me here.
