The Marvel's Eternals franchise didn't do well with audiences initially, but it has still made an impact on the Marvel Cinematic Universe.
The Eternals team prevents the birth of a new celestial which led to a big stone hand sticking out of Earth's ocean.
Several Marvel properties, including She-Hulk and Captain America: Brave New World, directly take on the plot-dangler left by Eternals and What If...? season 3 is the latest.
In What If... Agatha Went to Hollywood, Agatha Harkness transforms into a deity and defeats Arishem after absorbing fellow actor Kingo's power.
What If...? allows Marvel stories to drift away from Avengers spaciness and take on an expanded group of cultural customs and graphics.
Even though Eternals did not fit the Marvel Cinematic Universe's direction, it did stimulate new ideas with a unique blend of Pan-Asian cultural references and cosmological thriller.
Given the interest that the MCU properties have shown in Eternals, what seems clear is that the film has made its mythology an important aspect of future Marvel stories.
If Marvel continues to emphasize Eternals mythology in its future projects, it can make up for the lack of an Eternals 2, and Agatha may also get the big-screen treatment that her power set deserves.
It is inspiring to see such a strange and bold mythology at play in the ever-evolving MCU that can be further explored in future projects.
Although there are no immediate plans for Eternals 2, Marvel clearly seems interested in the mythology of the Marvel's Eternals and its implications for the future of the MCU.
