Now I know that Ant-Man has only been out for a few days, but after seeing that movie twice, I've been pondering where they could go if (or when) they make a sequel. As of this post, Ant-Man 2 has not been announced, but I bet there will be one. Alright, so I'm just going to go down this list and give my reasons why.
****ANT-MAN SPOILERS AHEAD****
Red Queen: Now in the comics, Hope Van Dyne is the Red Queen. Now, Marvel could do this one of two ways:
1. Have Janet return and be Red Queen while Hope is Wasp.
2. Have Janet return and Hope turns evil and become the Red Queen.
They could do this because as we've seen with Scott in the movie, it is now possible to come out of the Quantum Realm. Maybe with a little help from Doctor Strange?
Now these next two kinda tie into one thing that happens in the movie. Mitch Carson (the HYDRA dude that Hank hates in the flashback) steek the shrinking serum that Cross made and then we never see of him. So we could very easily see HYDRA in the sequel!
Black Ant: Now in the comics, Eric O'Grady is Ant-Man, then dies, and then is resurrected by Dr. Doom as the Black Ant. Now there is no way they could do this because of rights issues so maybe have Eric be a ex-SHIELD HYDRA agent use the Pym particles that Carson stole and become Black Ant!
Mitch Carson: This one seems the most likely because we see him take the particles at the end of the movie so maybe well see him become a shrinking Ant-Man villain like Black-Ant, Scarlet Beetle, or somebody entirely new because we've seen that Marvel is not afraid to change a villain's identity!
Taskmaster: Now this one could also tie back to the Carson theory because Taskmaster has worked with/for HYDRA a lot in the past and he has fought with Scott Lang many times in the comics.
Egghead: Now I'm surprised that Egghead wasn't the villain in the first Ant-Man movie because he was one of Ant-Man's first and most popular villains. I don't have any theories for how he could battle Scott Lang, but if the rumors are true that the next Ant-Man movie could be a prequel with Hank Pym, then maybe he could be the villain!
Whirlwind and Radioactive Man: Now I grouped these two together because I feel basically the same way with these two and Egghead, they're just iconic Ant-Man villains. Maybe they could both be in the movie together and then eventually set up a Masters of Evil in the movie!
Crossfire: Now I have a pretty cool idea for the Ant-Man sequel. So in the same way how Black Widow was apart of Captain America: the Winter Soldier, maybe Hawkeye could be in Ant-Man 2! This is because Crossfire is a pretty big villain to both Hawkeye and Scott Lang and it would also be could to have some of this if you know what I'm sayin:
Crossfire would also be good for the sequel because he is Darren Cross's cousin and maybe he could have some sort of revenge storyline in the movie!
Well, that's all for my theories, please tell me what you think in the comments below and make sure to leave your ideas as well!
