Eternity is an essential Marvel Comics character, as it was involved in the Infinity Stones’ creation during the Big Bang and has assumed the collective consciousness of all living beings in the universe, save for the Living Tribunal. Hopefully, the primordial being is further explored in the MCU, as Eternity often appears in storylines covering Dr. Strange, Mister Fantastic, Thanos, and the soon-to-debut Adam Warlock.
