The Winter Soldier Complete MCU Timeline: Bucky's Story Explained

The Winter Soldier (Sebastian Stan) has had quite a complex career in the MCU. James Buchanan Barnes is the childhood friend of Captain America, and both become men out of time, having lived very long lives thanks to their respective enhancements. However, up until 2016, Barnes hasn't always been in control of his own mind thanks to the efforts of Hydra, which lead to some fairly dark chapters in his life before he became an Avenger alongside Captain America in Avengers: Infinity War. As a result, this makes Barnes one of the most compelling and dynamic characters in the MCU.
