One aspect of the comic books that the MCU has always left out is the passing down of titles. That is soon to change though, as in ‘Ant-Man’ the mantle of the titular hero will be passed on from Hank Pym to Scott Lang. One name in the comics that has had many characters behind it is “Captain America”. Bucky Barnes, Sam Wilson, Steve Rogers and many others have held the title of ‘Captain America’ at one point or another, this is soon to be translated onto screen as well, as we know, either Bucky or Sam Wilson will take over from Steve, it’s more of a matter of when and not if at this stage. It may happen in the third Cap movie, but as Chris Evans is signed on to do another movie after that it could happen in part 1 or 2 of Infinity War. I think we could be seeing someone else under the Captain America title a lot sooner though.
In the comics, when Steve Rogers was MIA a second Captain America emerged, a second Super-Soldier injected with the same serum as Steve Rogers. (I don't know too much about this though, so if you want to research it further try googling it). As we know Steve was the only person injected with the super-soldier serum in the MCU, so that would rule out a second Cap wouldn’t it? Theoretically…yes. But as we also know, Marvel are not shy about changing origin stories for screen (Quake, Deathlok, The Twins, etc). So what’s to stop Marvel changing up a second Captain America’s origin story?
Note: MAJOR SPOILERS FOR “AGENT CARTER”
In the latest episode of Agent Carter it was shown that Howard Stark has a vial of Steve Rogers blood, he plans to use it to make medication and vaccines, not to make the world a better place, but to get his hands on some more money. If a situation came up, where he could make MORE money by doing something else with it, I reckon he would. I’m thinking along the lines of reverse engineering a super-soldier serum from the blood. Of course, he would need a volunteer and someone to fund him (once he gets his name cleared Im sure that wont be a problem). I think I know exactly who would volunteer: Agent Daniel Sousa. He is a war veteran and stands for all the things Steve Rogers does, he stood up for Peggy when everyone else was treating her like dirt. Him and Steve are similar in many different ways. You may also hear his name being thrown around when people are talking about who Peggy Carter’s husband might be. In fact, when questioned on who Peggy’s husband might be the show-runners said to keep an eye on Sousa and Thompson (another agent, who has all the qualities in a man that Peggy hates). When questioned about a possible relationship between Carter and Sousa, Enver Gjokaj who plays Agent Sousa said “I think there’s definitely a situation where … if she hadn’t dated Captain America, he might ask her out for a drink”. Even one of the other Agents made a throwaway line “She’s not going to trade in a red, white, and blue shield for an aluminum crutch”. I think if he was presented with the opportunity to be given a serum that could regrow his leg back, and also make him super strong, he would jump on it with both feet forward. (sorry). The actor who played Sousa also had a small cameo as a cop in The Avengers, now there is nothing to prove that these are the same person, but it might add a bit more back story if sometime the future someone makes a throwaway line about "Sausa gave up the Captain America mantle and went back to being a cop, he preferred the quiet life."
EVERYTHING PAST THIS POINT IS PURE SPECULATION AND IS LIKELY TO NEVER HAPPEN. (Although it would be pretty cool if it did.)
I reckon what’s going to happen is Sousa will find out about Peggy working behind the SSR’s backs, but instead of shaming her, he will work WITH Peggy, and will come into contact with Stark through her. After Starks name is cleared he founds S.H.I.E.L.D and the first two people he brings in is Sousa and Peggy. With Starks new resources ad government funding he will come up with a new supersoldier serum, and Peggy will recommend her new boyfriend Sousa to undergo the transformation, seeing the same qualities in him as she did with poor old skinny Steve. Stark will present him with his own new costume and shield, probably not vibranium, but maybe one of the other fancy shields that we saw in The First Avenger. Perhaps we will see an Invaders TV show? I mean Human Torch already exists, we saw him in The First Avenger. We could even see a trip to Wakanda or two in this show. All the awesome missions that Steve Rogers went on in the 40’s in the comics never got realized on screen. An Invaders TV show spanning 8 or so episodes done on the right budget would be a perfect way to show us some of the things that happened in the 70 year gap in the MCU, or at least fill in the bits Hank Pym’s storyline in ANT-MAN doesn’t.
So what do you think? Do you think my theory is too far-fetched or do you think it’s plausible? Sound off below, add onto my theory, and if there’s anything I missed let me know.
