Since his introduction in Captain America: The First Avenger , Bucky Barnes has been a key side character in the MCU as a close friend of Steve Rogers' — and now Sam Wilson's — Captain America.

Over the last ten years of the MCU, Bucky has been a World War II soldier, Hydra's Winter Soldier assassin, and now sits as an Avenger in his own right. Now, the character is finally set to take the lead alongside The Falcon in their upcoming Disney+ series, The Falcon and the Winter Soldier .

HAPPY BIRTHDAY, BUCKY BARNES

Today marks the 104th birthday of Bucky Barnes, the Winter Soldier. To celebrate the occasion, Bucky's MCU actor Sebastian Stan shared a series of new behind-the-scenes looks at his time as the character over the years.

The first image shows the actor in the process of having his long hair styled for a shoot. Meanwhile, the never-before-seen videos that follow showcase Stan in action, rehearsing a fight scene with fight choreographer Aaron Toney and stunt coordinator Sam Hargrave for a scene that appears to have been for Captain America: Civil War.

Stan captioned the new shots wishing his character a happy birthday and jokingly referring to the “interesting fights. And hairstyles” he's had over the years.

Last year, Stan also celebrated Bucky Barnes' birthday with an Instagram post, sharing a video of himself blowing out the candles of a birthday cake:

BUCKY TAKES THE SPOTLIGHT

Over Bucky's ten years in the MCU, the character has grown into a fan-favorite for many. The Winter Soldier finally taking up a lead role means fans will get to spend a lot more time with the Winter Soldier as they dive into his emotional struggles and trauma .

A big difference for the Avenger in the upcoming series can be seen in his hair. While in the past he's donned long brunette hair, Bucky's finally got himself a haircut with a stylish new look. The epic Marvel series has promised cinematic-level action and the Winter Soldier's past track record when it comes to action spectacles makes the project one of the most exciting of the Phase Four line-up for many.

The Falcon and the Winter Soldier will debut exclusively on Disney+ on March 19, 2021.
