There’s a Thanos-sized hole in the Marvel Cinematic Universe, and we’re still not sure what supervillain will fill it. To be fair, Marvel has plenty of time to figure things out before Avengers 5, which probably won’t unite Earth’s mightiest heroes again for a few years at the very least.
But with Eternals on the horizon, is it possible this millennia-spanning adventure could be our first big hint at the MCU’s big bad? A new fan theory argues this exactly, while pointing to an overlooked moment from 2014’s Guardians of the Galaxy as our first big clue at who Marvel’s Thanos replacement might be.
On the Fan Theories subreddit, u/JayNotAtAl argues that 2021’s Eternals “will explain the death of the Celestials and perhaps hint at a future return.” What does this mean? Well, we know that the Celestials (god-like intergalactic beings invented by Marvel Comics legend Jack Kirby) will make an appearance in Eternals, which makes sense since they created both the Eternals and their enemies, the Deviants, by meddling with human evolution.
