The next big Marvel Studios release to grace the big screen will be Chloe Zhao’s Eternals, which will see the MCU version of the team. We already know that the film incarnation will be different than their comic book counterparts and a new detail might help link them to a similar group of god-like aliens.
Marvel’s Nate Moore recently revealed to Comic Book another slight tweak to the Eternals origin, stating the group of immortals are from an alien planet called Olympia.
“In the past we see the Eternals, who, in our version of the mythology, are immortal aliens from a planet called Olympia. [They’ve] been asked by the Celestials to come to Earth to rid the Earth of creatures called the Deviants. The Deviants are these parasitic aliens who go from planet to planet, and as they kill the apex predators on a given planet, they sort of take the characteristics of those predators and wipe out intelligent life. Well, the Eternals are heroes, so they’ve come to earth to eradicate the Deviants and allow humanity to thrive.”
In the comics, Olympia aka High Olympus was set on Earth in Greece.

Interestingly enough, The Olympians (Marvel’s cosmic version of the Greek pantheon of gods) will be officially introduced in Thor: Love & Thunder after Australian actor Russell Crowe revealed he’d be playing the MCU version of Zeus in the sequel.
I don’t exactly see why Marvel wouldn’t have Zeus and The Olympians also being from this planet of Olympia as a streamlined way to be less confusing to audiences by making the groups essentially interchangeable. This might also be why Zuras (Thena’s father) isn’t in the film, both Zeus and Zuras have similar character designs in the comics.
Zeus, of course, is the father of demigod Hercules Panhellenios aka The Prince of Power, who just happened to be on The Avengers roster around the same time as Gemma Chan’s Sersi and Kit Harington’s Dane Whitman aka Black Knight.
Adding a bit of fuel is that director Chloe Zhao told Empire Magazine that the Eternals are “akin to stories of Greek and Roman gods, who live very human lives with human traits, rivalries, jealousies and frailties.”

It’s hard not to notice this information only further distancing themselves from Thanos and Titan. In the trailer, Ajax (played by Selma Hayek) explained that The Mad Titan wasn’t a Deviant, which prevented them to interfere with his dastardly plan to kill half the universe (addition of Olympia could suggest he’s not an Eternal either). This line was also likely out of convenience because Marvel wasn’t even thinking about bringing Jack Kirby’s obscure creations, The Eternals, into the MCU until Chloe Zhao pitched them on the idea.
However, nothing stops them from making Titans like Starfox part of the Eternals/Olympian group.
The MCU version of Deviants could also have a larger connection to Lemurians and world of Namor/Atlantis, if Lemuria and Atlantis both were sunk during The Great Cataclysm (potentially shown in Eternals). This might explain why we see Deviants coming out of the ocean in the trailer footage and possibly where they’ve been hiding out for 5,000 years until the events of the film.
I guess we’ll have to wait and see when Eternals releases on November 5.
