11. Spider-Man, Far From Home - Nick Fury And Agent Hill Were Skrulls
Far from Home was loaded with bombshells, and they kept on coming. The final second post-credit scene was a jaw dropper for roughly one second. When Agent Hill began morphing into a Skrull shade of green, fans most likely relished in the prospect of her turning out to be a Skrull refugee all along. But when Fury began morphing also, that seemed not the case. Or did it? Seems we're still trying to work that one out.
Anyway, it turns out that the Nick Fury of the Far From Home variety was actually Talos of Captain Marvel fame, while the real Fury spent the film housed up in a Skrull spaceship, the purpose of which will most likely be revealed in a later movie.
The trouble with this, is that the unsolved chasm of who was who and when is way too vast. While we are supposedly to assume that the masquerade lasted only for that particular movie, the lack of concrete correspondence has left fans second-guessing the validity of Fury across the entire MCU run.
Ultimately, this twist was a largely unnecessary addition to the film.
