Avengers.

Steve—Steve Rogers, known as Captain America—is the world's first superhero, a World War II veteran and the undisputed leader of the Avengers. Before the war, Steve was a sickly, small, and incredibly thin kid from Brooklyn whose ailments prevented him from joining the army. His greatest asset was his unbreakable willpower and willingness to protect the weak, and thanks to the serum, he was able to reach the peak of human capabilities.

Vision is a unique android synthezoid created through a combination of vibranium, artificial intelligence, and the energy of the Mind Stone.

Wanda – Along with her twin brother, Pietro (Quicksilver), she volunteered for experiments by the terrorist organization HYDRA, where exposure to Loki's Scepter (Mind Stone) awakened her latent magical abilities. Initially, she opposed the Avengers out of personal vendetta against Tony Stark (whose weapon destroyed her home and killed her parents), but later recognized the threat of Ultron and defected to the heroes. She is currently in a relationship with the android Vision (who houses the Mind Stone).

Sam is a former US Air Force pararescue diver who became a loyal friend and ally of Captain America. He flew using a special military jetpack with transformable mechanical wings (the EXO-7 Falcon) and piloted a reconnaissance drone named Redwing.

Bucky previously served alongside Steve in the Soviet Union's military. During World War II, Bucky fell from a HYDRA train into a snowy chasm in the Alps. Thanks to Arnim Zola's early experiments, he survived, but his left arm was irreparably damaged. HYDRA scientists completely amputated it and replaced it with the first metal prosthetic, turning Bucky into the Winter Soldier. But thanks to Steve, he has now been able to free himself from HYDRA and is recovering.

Pepper is Tony's wife and assistant (or rather, Tony runs errands for her). They have a 5-year-old daughter, Morgan Stark. She's smart and very perceptive, doesn't put off work and gets it done on time.

Stephen is the Supreme Warlock of New York. He used to be a doctor, but an accident shattered the bones in his hands into tiny fragments, and severely ruptured and pinched nerve endings left him with a constant, severe tremor in his fingers. But after some time, he managed to find a place where he was trained in magic and managed to overcome it, so now he is the Supreme Warlock.

Thor, the god of thunder, is the second lawful heir to Odin's throne. He doesn't yet know about his sister's existence, but he should find out in a couple of years. He's arrogant, but always cares for his friends and family, especially Loki.

Loki is the god of deceit and lies; he loves to have fun, annoy everyone, and generally does nothing. A couple of months ago, he attacked New York, then lost to the Avengers and was sent back to Asgard. But Thor brought him back, feeling guilty that his free brother had become this way because Odin hadn't paid enough attention to him. But mostly, Loki only stays in the tower and can't go anywhere else.

Peter is a high school student and Spider-Man. Peter's parents died when he was young, and he grew up with Aunt May and Uncle Ben, but Uncle Ben died a few years later. He was bitten by a spider, which heightened his senses to 11. He doesn't join the Avengers because Tony is against it and he needs to finish school.

Bener is a scientist who became the Hulk as a result of an accident during a scientific experiment involving gamma radiation. He tries to control the Hulk, but it seems the Hulk is controlling him. He's also on the Avengers team.

Clint is an archer with excellent eyesight, crafting arrows with various powers (explosives, poisons, and the like). He has a wife and three children. He is also a member of the Avengers team. He will only stay for half a day for the holiday, and then go celebrate with his family.

Natasha Romanoff was a Russian spy who trained from childhood in the Soviet organization "Red Room," a place where girls were trained to be assassins. She has an adopted sister, Yelena Belova, but they are currently in different countries. However, she is currently a member of the Avengers.

Tony Stark is a billionaire, playboy, philanthropist—in short, a technological genius. While imprisoned in a cave, Tony built a miniature arc reactor and his first suit, the Mark 1, from scrap metal and junk. But now he's a member of the Avengers, saving the country.
