It’s unclear if it was always the plan for X-Men: Dark Phoenix to include the Skrulls, particularly since they didn’t play any role in the original Dark Phoenix Saga, but assuming this report is true, then the X-Men universe’s versions of these aliens will debut four months before the MCU versions.
It would also be interesting to see how the X-Men Skrulls are visually different from the MCU Skrulls in their natural forms.
This wouldn’t be the first time that an X-Men movie has beaten the MCU to adapting a character for the silver screen first.
2014’s X-Men: Days of Future Past introduced Evan Peter’s Quicksilver, who was brought in to replace Juggernaut, and a year later, Aaron Taylor-Johnson brought the same speedster to life in Avengers: Age of Ultron.
