James Buchanan "Bucky" Barnes is a World War II veteran, former officer of the 107th Infantry Regiment and the best friend of Steve Rogers since childhood. Barnes had enlisted into the Army following the attack on Pearl Harbor and was assigned to the 107th in 1943.
I never read the Cap comics, but I've watched Captain America: The Winter Soldier a few times now, and Cap proclaims that Bucky's full name is "James Buchanan Barnes," and according to wiki he is named after the former President, James Buchanan.
We see that he's deprogrammed 6 months before the snap in FATWS. He's then snapped away and comes back 5 years later. FATWS takes place 6 months after he comes back. So Bucky is likely 33 physically while chronologically being 107 (FATWS takes place in April 2024, so Bucky's wrong about being 106).
Taking the experimentation, cryogenic freezing and time skips into consideration, Bucky is physically somewhere in his mid-30s by the time The Falcon and the Winter Soldier takes place, making him appear seventy-some years younger than his chronological age.
Surviving the war and believing Captain America's death, Bucky eventually marries Gail Richards and has a large extended family. During which, Bucky is diagnosed as having lung cancer from chain smoking back in the War. Barnes and Gail both live to see Steve's revival in the 21st century and renews their friendship.
However, Barnes actually survived the fall thanks to the experimentation Zola had performed on him, and it was HYDRA who would make use of the man who would come to be known as the Winter Soldier...
While under control of the Russians, Barnes meets and begins falling in love with Natasha Romanoff, who goes onto become the Black Widow. He reunites with her after regaining his senses in the modern era.
Bucky Barnes, like Steve Rogers, has lived for several decades due to cryogenic freezing and the super-soldier serum. Bucky's life expectancy could potentially surpass Steve's 116 years, depending on circumstances. Despite outwardly aging at the same rate as Steve, Bucky can still live for at least another 80 years.
The Bucky Barnes of the Marvel Cinematic Universe is based off two characters from the comic books: James “Bucky” Barnes who was Captain America's sidekick, and Arnold “Arnie” Roth who was Steve Rogers' childhood best friend and defender from bullies. Arnie is Jewish and gay in the comics.
Rebecca Barnes was the daughter of George Barnes and Winnifred Barnes and the younger sister of James Buchanan Barnes. She grew up with her family in Shelbyville, Indiana.
Even Bucky's variant serum should allow him to age normally (unless he gets frozen again). A side effect of the Super-Soldier Serum that the Winter Soldier shares with Captain America is that neither can get drunk.
According to Google, comics Bucky was born March 10, 1917. If we presume that's the case for movie Bucky, he'd have been 24 when the US declared war against Japan and 28 when the war was in it's closing days, which is generally the time frame for when he disappeared.
Surviving the war and believing Rogers had died during his last mission, Bucky eventually married Rogers' fiancé, Peggy and had two children, Marvin and Rebecca.
Early Life. James Buchanan "Bucky" Barnes was born in 1925. In 1935, he tragically lost both of his parents early in his life; his mother, Winnifred Barnes had died when he was a child and his father, George Barnes had died in an accident while in basic training at Camp Lehigh.
Based on previous scenes in the MCU, it's apparent that Bucky for sure speaks and understands Romanian, Russian, German, and Japanese, as well as his native English, of course.
Ever since becoming the Winter Soldier, Bucky has been known for his cybernetically-enhanced prosthetic left arm. It was originally given to him by HYDRA, but the Wakandans gave him a vibranium arm after the original was destroyed.
