In the Marvel comic books, Eternity is even more powerful than he appears to be in the MCU. Eternity is actually the embodiment of the Universe, along with his sister, Infinity. According to the comics, Eternity is a cosmic-level entity, but not a Celestial, as the Celestials are a specific type of cosmic being created by the First Firmament. In fact, Celestials are part of Eternity, as is the entire Marvel universe.

It can be tricky to wrap our heads around, especially because Eternity can take a physical form. However, Eternity subsists on everything that exists within the universe, and the universe exists because of Eternity. In one storyline, Captain Marvel works with Eternity’s son, Entropy, to kill Eternity, but in doing so, they destroy the universe. They later regret this, and Entropy becomes the new Eternity.

In the Marvel comics, the only being more powerful than Eternity/Infinity is the Living Tribunal, who embodies the multiverse rather than the universe. And although it seems like Eternity is omnipotent, his opposing force is Death, while Infinity’s opposing force is Oblivion. Together, these four cosmic beings make up the four corners of the Marvel universe.

It’s unclear if Eternity will have this level of power within the MCU, but it’s possible that we can definitely see and hear more about him. Perhaps he’ll make an appearance in Loki Season 2, in which the sanctity of time is put into question.
