As part of the contest, here is my theory for a post credits scene in Ant-Man (If there is one)!
Ant-Man (Paul Rudd) is looking at a computer screen , just checking out the latest national news.
Then he's sees a thumbnail of the one and only...Tony Stark! He clicks on the video to find out that Tony Stark and other politicians announce a system of accountability and a governing body that forces superheroes to work for the government!
Scott is shocked! He stops the video, then he looks down in serious thought, and then he looks to his suit, the camera then focuses on the suit, then cuts to black!
Then afterwards it appears "Ant-Man will return in Captain America: Civil War"
So what do you think, comment below and let me know!
