MCU Phase 4: 9 Insane Fan Theories You Won't Believe

2. Nick Fury Against Red Skull (Also He's A Skrull... Maybe)

One of the stranger absences from Phase 3 has been Samuel L. Jackson's Nick Fury, who we last saw in Age of Ultron and in the first season of Agents of S.H.I.E.L.D.

Bar that, Fury's yet to make a Marvel comeback. His name's been mooted for the upcoming Captain Marvel prequel, but he's yet to resurface as of 2017. Even SLJ himself seems slightly perplexed as to the situation at hand, with confusion surrounding his role (or again, lack thereof) in Infinity War leading fans to question whether the MCU still has place for everyone's favourite S.H.I.E.L.D. Director.

That said, there were suggestions a while back that the Pulp Fiction star actually let slip what Fury's been up to, in that he's been tracking down the Red Skull who, wouldn't you know it, looks to be alive and well. While there's a chance we could all be misinterpreting Jackson's comments (certainly so, in light of his involvement in the Skrull-oriented Captain Marvel movie), the chance to see Fury going toe-to-toe with Steve Rogers' arch-nemesis would make for a particularly brilliant feature.

Other Fury-based rumours have posited that he could, potentially, be a Skrull. While it would take a tremendous amount of goodwill from fans to accept that the Fury they've known all-along is actually an alien invader, the former Director's candidacy for a role as an alien spy certainly seems strong, especially if Marvel follow a certain storyline from the comics...
