So far in the Captain America movies, we have had villains and story arcs that were pretty obvious choices. (Not bad, mind you, just obvious). With a character like Captain America, the first movie absolutely had to be an origin story, otherwise there would be a lot of confused movie goers. It set up the Winter Soldier and the return of Bucky Barnes perfectly, and I honestly feel that the Winter Soldier is one of my favorite Marvel movies to date.
Now with [Captain America 3](movie:994409) on the horizon (2016), the possibilities are much more open. At this point, and especially after Age of Ultron, Cap is fully established and loved by audiences in his own right. The best thing about this (other than more movies around him, which is awesome!) is that it gives the writers a chance to explore different villains and story arcs.
Christoper Markus and Stephen McFeely, the writers for the movies, have started to speak out about who we might see as the enemy in the upcoming film. Thus far, they haven't given us much, but have said that we will not be seeing the crazy "Captain" from the 50s, and now they have talked a little about a couple of villains that they would like to see, in a recent interview with SFX.
That's a little tricky because some of them are theoretically very good. Some of them have great concepts but are really tough to pull off visually. Like Flag-Smasher who wants to destroy nations, and that's a terrorist and seems like a guy you could work with, but he literally has a cape and flies on flying skies, and then you're like, 'Ok, do we take away everything?' and then he's just a guy and we're not fully portraying the character.
Flag-Smasher is a great possibility for the third installment, in my mind. Sure, he has some flying skies, but I think that they would be able to find a way to do some costume changes and still make it work. The really interesting thing about a villain like Flag-Smasher is the terrorist angle. Just look at the massive popularity of V for Vendetta with the Occupy movement, and it's easy to see that a lot of people want an enemy that they can connect to the real world.
Flag Smasher also gives us some possibilities for future crossovers and links to the villains we have already seen. ULTIMATUM and Red Skull have crossed paths, and it would be really interesting to tie the three films together as much as possible, the way that Marvel already has with The First Avenger and The Winter Soldier.
Downsides for Flag Smasher may be his lack of actual superpowers (although that hasn't stopped everyone loving Black Widow!), and that he is possibly a little cliche; America vs Terrorist may hit a little too close to home for some.
The other possibility talked about is (as if the picture didn't give it away!) MODOK!
I always wanted to do MODOK., but it seems like we're leaving our grounded political arena way behind when you've got a giant floating head on a rocket chair. I'll do it one day, I'm telling you people!
On the one hand, I would actually really like to see a giant, floating, rocket-propelled head. I think that CGI is up to the task, and we've seen some impressively weird things happen in comic-book movies before. With the right designers, this could look amazing! Of course, in the wrong hands, this would end up being utterly ridiculous, so it's definitely a wait-and-see. I do also really like that maybe MODOK could cross over into the tv-verse with [Agents of S.H.I.E.L.D.](series:722469), but being two years away means that we don't even know if the show will still be running.
Clearly the writers themselves are very into the idea of MODOK, and usually the characters are better when the people writing them are fans, so I have faith that these guys could pull it off. Whoever they choose, I know that I am going to love it!
