In The Fantastic Four: First Steps’ tie-in comic, the titular superhero team battle Giganto on the streets of their retro-futuristic, 1960s-inspired New York. This mirrors the Fantastic Four’s first battle in Marvel Comics back in 1961, in which Giganto was revealed to be a Deviant Mutate โ the product of an experiment by Deviant scientists working for Kro. Marvel Studios altered this story somewhat by making Giganto in the new comic a Deviant in his own right, calling back to the Deviants introduced in Eternals, but this creates some confusion.

In Marvel Comics, the Deviants were an offshoot of early humanity created during Celestial experiments a million years ago โ experiments that also created the Eternals and Mutants. For 2021’s live-action Eternals, Marvel Studios changed the Deviants’ history, instead making them biological beings created by the Celestials to protect Celestial seeds planted in select worlds. The Eternals were subsequently created as synthetic beings who were tasked with eliminating the Deviants when they evolved out of control. This changed origin means there’s no way the Deviants could have carried out experiments that created Giganto in the MCU.
