Which Characters Work as Skrulls?
Of course, not every Avengers is a franchise lead. We can rule out the likes of Captain America, Iron Man, Thor, Spider-Man, and even the Hulk; but that doesn't mean some of the secondary Avengers couldn't be Skrull impostors instead. Let's take a look at the other members of the Avengers.
It's safe to say that Hawkeye isn't a Skrull impostor. The whole purpose of the Skrull invasion is to infiltrate the Avengers, and Hawkeye's entire character arc is focused around the idea that he actually wants to retire. In the aftermath of Captain America: Civil War, he's spent the last two years under house arrest, and the Avengers didn't even call him in for the Battle of Wakanda in Avengers: Infinity War. Hawkeye is literally the last person the Skrulls would want to replace.
A more promising target would be Black Widow, although again her character arcs from The Avengers through to Avengers: Age of Ultron are a little too pronounced for her to have been a Skrull impostor that far back. But she's ideally positioned to become a huge asset to the Skrulls; a close friend of Steve Rogers, and someone who has a romantic history with the Hulk. What's more, Black Widow's every secret is probably available to the aliens; when she uploaded the S.H.I.E.L.D. database onto the Internet in Captain America: The Winter Soldier, Black Widow told the world everything S.H.I.E.L.D. knew about her. This super-spy's life story is public knowledge. It's true that Marvel is working on a Black Widow movie, but that doesn't rule this idea out. In the comics, the "Secret Invasion" arc saw one Avenger return from the dead, Mockingbird, and she then had to spend time acclimatizing to a world that was very different to the one she knew. In the same way, it's possible the Black Widow script will be centered around Black Widow's return to Earth, and her attempt to rebuild her life.
Scarlet Witch can probably be ruled out as a Skrull. Although the aliens can mimic powers, it's doubtful they'd be able to duplicate the resonant frequency of an Infinity Stone, so the fact she could destroy the Mind Stone rules her out. Meanwhile, the fact that Vision had the Mind Stone in his forehead - and didn't turn back into a Skrull when Thanos removed it - proves he isn't a doppelganger.
That only leaves two other possibilities; Falcon and Winter Soldier. There's no reason the Skrulls would duplicate Bucky, given he's one of the world's most wanted and is hardly free to move with impunity. What's more, like Hawkeye, Bucky has exerted far too much effort into keeping his head down. Falcon, on the other hand, is a definite possible candidate. In narrative terms, he doesn't really have a story of his own; Sam has basically been relegated to the role of sidekick. That leaves him close enough to Steve Rogers for the revelation to be a shocking and emotional one.
Moving to Wakanda, it's unlikely the fictional African nation has actually been infiltrated by Skrulls at all. Until recently, Wakanda was believed to be a backwards country that kept itself to itself. That seems to have only just begun to change, and the Skrulls - like the rest of the world - will no doubt be taken by surprise when they realize just how advanced the Wakandans really are. The secretive nature of Wakandan culture would also make it very difficult for the Skrulls to get into Wakanda, as the aliens would have no knowledge of the traditions they'd need to appear to honor.
Of all the Avengers, then, there are really only two who could potentially be Skrull impostors: Black Widow and Falcon. The rest can safely be dismissed, for a wide range of reasons. For some, their being a Skrull would distort the MCU's ongoing narrative far too much, while for others it just wouldn't fit with the story we've seen build up over the course of the last decade. Of course, the truth is that we don't actually know that Captain Marvel will actually be the trigger for a "Secret Invasion" film at all. It could just as easily be "Secret Invasion," blending the Kree-Skrull War with a more recent comic book plot. We likely won't find out more until next year.
