As a Watcher, the character possesses a number of superhuman abilities, including strength, speed, agility, and durability. He also has access to advanced technology, including a number of powerful weapons and gadgets. Despite his powerful abilities, the Watcher is bound by his oath of non-interference, and he is not allowed to use his powers to directly interfere in the affairs of other beings. However, he has been known to bend or even break this oath on occasion, when he believes that it is necessary to prevent great harm or destruction. Throughout his long and storied career, the Watcher has observed and recorded countless events in the Marvel Universe, including the rise and fall of civilizations, the births and deaths of heroes and villains, and the struggles of ordinary people.

Winter Soldier, also known as James Buchanan "Bucky" Barnes, is a Marvel Comics superhero who was first introduced in Captain America #1 in 1941. He was created by Joe Simon and Jack Kirby. Bucky was originally portrayed as Captain America's teenage sidekick, serving as his partner in the fight against the Axis Powers during World War II. However, in a tragic turn of events, Bucky was presumed dead after a mission gone wrong, leading to Captain America being frozen in ice and preserved for several decades. Decades later, Bucky was revealed to have survived the mission and had been brainwashed by the Soviet Union to become a deadly assassin known as the Winter Soldier. He possesses superhuman strength, agility, and endurance, as well as extensive combat training and knowledge of espionage. The Winter Soldier's most notable power is his bionic left arm, which is capable of crushing metal and firing energy blasts. The arm is also equipped with various gadgets and weapons, including a retractable knife and a grappling hook. Despite being brainwashed for years, Bucky eventually regained his memories and went on to become a hero in his own right, even taking up the mantle of Captain America for a time. Throughout his history, the Winter Soldier has faced off against numerous foes, including Captain America himself, who was initially suspicious of Bucky's motives after he resurfaced as the Winter Soldier. However, Bucky has proven himself time and time again as a valuable ally and hero, using his formidable skills and determination to protect the world from threats both foreign and domestic. The Winter Soldier has also made multiple appearances in the Marvel Cinematic Universe, portrayed by actor Sebastian Stan. He remains a popular and iconic character in the Marvel Universe, known for his strength, cunning, and unwavering loyalty to those he considers family.
