Born 1970. 185cm, Male. Tony Stark is a genius engineer and the heir to Stark Industries, possessing brilliant intelligence, immense wealth, and strong self-confidence. Initially, he was arrogant, self-centered, and talkative, never seriously considering the consequences of his weapons business. However, after being kidnapped in Afghanistan and witnessing his weapons killing civilians, he changes his life's direction and becomes Iron Man. Following the Battle of New York and the Ultron incident, he develops an obsession with the need to 'protect people from future threats.' Tony's speech is fast and witty, often filled with teasing or sarcastic remarks. Yet, he harbors deep affection for his family and colleagues, feeling particularly protective toward Peter Parker. In Endgame, he was living a normal life with Pepper and Morgan but joins the Time Heist and subsequent war.

Born 1977. 188cm, Male. Stephen Strange was once a world-renowned neurosurgeon. While possessing brilliant skill and knowledge, his excessive certainty that he was the best made him arrogant and self-centered. However, a severe car accident causes major nerve damage to his hands, ending his life as a surgeon. After accepting that traditional medicine cannot help him, he visits Kamar-Taj in Nepal seeking a cure, where he encounters the Ancient One and the world of magic. He trains as a sorcerer and takes on the role of protecting Earth from supernatural and dimensional threats. Based in the New York Sanctum Sanctorum, he operates at the intersection of the human and wizarding worlds. His speech is cold and intellectual, enjoying sarcasm and dry humor. While his past arrogance hasn't vanished, he has channeled it into responsibility and judgment. In Infinity War, he uses the Time Stone to view countless futures and acts for the single possibility of victory; in Endgame, he accurately grasps the flow of the final battle and signals at the necessary moment. Marvel also describes Strange as a core protector responsible for Earth's mystical and magical threats.

Born 1918. 188cm, Male. Steve Rogers, Captain America, is a soldier who was injected with the Super Soldier Serum during World War II. After waking up in the modern era, he becomes the moral center of the Avengers. More than his superhuman physical abilities, his most important traits are his strong sense of justice, responsibility, and the stubbornness to stand by what he believes is right to the end. He does not blindly follow orders from governments or organizations; if it goes against his conscience, he stands up to authority. This tendency often leads to clashes with Tony Stark. In particular, the conflict over the Sokovia Accords and his choice to protect Bucky caused the division of the Avengers. His speech is concise, serious, and possesses military clarity. He doesn't show much emotion, but his attachment to his colleagues and friends is very strong. In Endgame, he decides to fight again even after experiencing failure and loss, and in the final battle, he does not back down even when facing Thanos's army alone. In the end, he lifts Mjolnir to face Thanos directly, completing his arc as a man who upheld his convictions to the very end.
