One word that could describe the future of the MCU is mysterious. The future slate of films on Marvels radar have few details available regarding their plot. One such film, The Thunderbolts, is a prime example of this. Only a handful of characters are lined up to give fans a glimpse of what the team of anti-heroes will be up to. However, characters like Bucky Barnes and the U.S. Agent version of Captain America may hint at what storyline the film could be adapting: Captain America: Cold War.
