Around six weeks from now, a little-known movie known as [Captain America: Civil War](tag:994409) will hit theaters. It may be on your radar. The trailer did hit 100 million views in 24 hours, and at least 99 million of those did not come from bots at Marvel HQ.
In all of the crazy hype around the third Captain America flick, all of the chatter about who's on what team and the clash in ideals between two friends, there's not been a lot of talk about absent heroes, which got me thinking: which Marvel characters who aren't in Civil War might in fact have a secret cameo?
1. The Hulk
Hulk has endured a bumpy ride in the Marvel Cinematic Universe, beginning with that ill-fated solo movie with Edward Norton, before Mark Ruffalo took over and increased the big green guy's popularity. Age of Ultron may have been messy, but Bruce Banner was consistently the best thing about it.
His absence in Civil War feels conspicuous. Hulk's powers are way beyond those of Black Widow, Captain, Hawkeye or Ant-Man — maybe he needed to be removed from the equation to level the playing field. But really, will Steve not make any attempt to recruit Banner for the big fight? Don't bet against it.
Chances of a Hulk cameo: 45%
Another hero you'd expect to get involved (although as an Asgardian, whether he'd have to register as a superhero on Earth is perhaps debatable), Thor would be a handy ally for either Cap or Tony in this battle.
We know he'll be teaming up with Hulk in [Thor: Ragnarok](tag:956858), so perhaps an after-credits scene will be used to set up their inter-galactic adventure, but any kind of role in the film proper feels like a long shot.
Chances of a Thor cameo: 30%
3. Red Skull
There are numerous persuasive reasons to believe that Red Skull could have a part to play in Civil War. In a way it would bring Captain America full circle, the villain from his first movie returned to wreak havoc just as Captain's own arc draws to a close (if the outcome of the comic storyline is mirrored in the movie, that is).
Daniel Brühl, who's playing Baron Zemo, revealed recently that this incarnation of the character is only "loosely connected" to the Zemo of the comics. Could it be that Baron Zemo is a guise adopted by a scheming, resurgent Red Skull? I'm totally here for that.
Chances of a Red Skull cameo: 50%
4. Betty Ross
The daughter of General Thunderbolt Ross is probably not the first name on anybody's Civil War twist wish list, but her father is among the most important characters in the film - he's the driving force behind the government's attempt to monitor, control, and perhaps remove the Avengers.
William Hurt describes his character as having "a fanatical anti-superhero point of view"... which gets a lot more interesting if his daughter, Betty Ross, appears in Red She-Hulk incarnation. Would Marvel would use a film without the Hulk to introduce Red She-Hulk? Probably not, but chances are Betty could have a minor role to play here in non-superhero guise.
Chances of a Betty Ross cameo: 40%
5. Agent Peggy Carter
I had to save the best for last.
She may have her hands full in Hollywood in Agent Carter, but Peggy gets around. We've seen her in extreme old age in The Winter Soldier, in an '80s flashback with Hank Pym in Ant-Man (which stole the entire movie), and as a hallucination of Steve's in The Avengers: Age of Ultron.
Basically, a Marvel movie is never the real deal unless it features Peggy Carter. If Civil War takes place two years after The Winter Soldier, it would make sense that Peggy might finally have reached the end of her long, adventure-filled life – but opening the movie at her funeral would set an appropriate tone for the difficult battle ahead.
Don't let us down, Kevin Feige. I'm not ready to say goodbye to Peg quite yet.
Chances of an Agent Carter cameo: 80%
