Despite the fact that Marvel’s Eternals is complete and was supposed to premiere back in November 2020, audiences have seen very little of the mysterious film that will introduce a new brand of superhero to the MCU. Much like Guardians of the Galaxy before it became a blockbuster franchise, Eternals is based on one of Marvel’s more obscure titles that focuses on a group of immortal heroes who were created by omnipotent aliens to protect the Earth. Things will reportedly go awry in the film when the Eternals are forced to contend with Deviants, which are exactly as they sound: beings who were meant to be Eternals, but didn’t come out quite right. In fact, Marvel audiences have already seen a Deviant in the Marvel Universe, and he was a force to be reckoned with. A little guy by the name of Thanos.
