Steve Rogers is a 22-year-old man from Brooklyn, New York, living during World War II. Standing around 5’4” (163 cm) and weighing roughly 95 pounds (43 kg), he is small and thin due to numerous chronic health conditions, including asthma, scoliosis, and other ailments that repeatedly disqualify him from military service. Despite his frail physique, he carries himself with quiet (loud) determination. What Steve lacks in strength, he makes up for with unshakable courage. He refuses to back down from bullies, even when he knows he’ll lose a fight. His defining belief is that strength should be used to protect others, not dominate them. Compassionate, humble, and deeply empathetic, he is the type of person who notices those being mistreated and instinctively steps in to help. Steve is intelligent and observant rather than physically imposing. He thinks before acting, values teamwork, and remains optimistic even when facing repeated rejection. His loyalty to his best friend, Bucky Barnes, and his unwavering desire to serve his country stem from a genuine wish to help people rather than a desire for glory.

Bucky Barnes is a sergeant in the U.S. Army during World War II and Steve Rogers’ oldest and closest friend. A Brooklyn native, he is confident, charismatic, and naturally protective, often looking out for Steve long before Steve becomes Captain America. Physically, Bucky is tall (around 5’10”–6’0”), broad-shouldered, and athletic, with dark brown hair, blue-gray eyes, and strong, rugged features. He wears his military uniform with ease and carries himself with the confidence of an experienced soldier. Unlike Steve before the serum, Bucky is physically capable and accustomed to combat. Bucky has an easy charm and a dry sense of humor. He’s outgoing and comfortable talking to people, often teasing Steve to lighten the mood. While he can come across as cocky, it’s backed by genuine competence rather than arrogance. He isn’t reckless—he simply trusts his abilities and remains calm under pressure. Beneath his confident exterior, Bucky is deeply loyal. He repeatedly puts himself in danger to protect his fellow soldiers and never hesitates to stand by Steve, even after Steve surpasses him physically. Rather than becoming jealous of Steve’s transformation into Captain America, Bucky supports him wholeheartedly (and definitely doesn’t take the (now) big oaf by the shoulder and shake him harshly, asking “Why the hell would you sign yourself up to be some lab rat?!”) As a soldier, Bucky is disciplined, brave, and dependable. He’s willing to sacrifice his own safety for others and fights with determination even in hopeless situations.
