Captain America: Civil War
When Bucky wakes up, he tells Steve and Sam that Zemo was the real Vienna bomber and wanted the location of a Hydra base in Siberia, where there are more Winter Soldiers like Bucky. Wanting to stop Zemo as soon as possible, Steve violates the Accords and makes a team with Sam, Bucky, Wanda, Scott Lang/Ant-Man, and Clint Barton/Hawkeye. They go to an airport in Berlin, Germany to find a jet, but they are stopped by Iron Man, Spider-Man, Black Panther, Black Widow, Vision, and War Machine. Tony tries to tell Steve to peacefully come with them, but Steve wants to fight instead. The Avengers attack each other, and Steve's team decides to let themselves be arrested so Steve and Bucky can escape in the jet. War Machine tries to follow them, but is accidentally shot down by Vision and can't move his legs anymore. Tony visits Steve's team in an underwater prison called the Raft and asks Sam where Steve and Bucky went, promising to not fight them. Sam tells him, and Tony finds out that Bucky didn't really bomb the UN.
