When Eternals premiered in 2021, the emergence of Tiamut in its climax felt like a big deal. The Marvel film revealed that a dormant celestial had been slumbering within the Earth for thousands of years, and positioned his awakening as another direct threat to our planet. The Eternals managed to stop Tiamut from breaking out of his cocoon, but his frozen body, looming somewhere in the Indian Ocean, was never disposed of.
Tiamut has haunted the MCU’s margins ever since. Despite the Celestial’s potential to mix up future Marvel stories, he’s scarcely been mentioned outside Eternals. That odd state of affairs is finally set to change in the upcoming Captain America: Brave New World, which will bring us back to “Tiamut Island” for the first time in almost four years. Writer and director Julius Onah seems keen to make up for lost time, as Tiamut plays a crucial role in the film while also boasting a connection to a fan-favorite X-Men character.
