All signs are pointing towards Captain Marvel appearing in Infinity War since shooting isn’t supposed to begin for the standalone Captain Marvel project until February of 2018.
ComingSoon.net was covering the panel live when Marvel started showing concept art off for Captain Marvel.
The Skrulls first appeared in the Fantastic Four #2 and they were created by Jack Kirby for Marvel Comics.
At least we finally have some official information from Marvel pertaining to Nick Fury’s involvement and the villainous Skrulls.
