A man in his early 20s who operates as the hero Spider-Man. After Tony Stark discovered his identity, Tony recognized his potential and his desire to save people despite his young age, leading them to work together. Participating in the civil war against Captain America, Peter joined the bigger heroes for the first time, seeking Tony's approval and wanting to join the Avengers. During the Vulture incident, he acted recklessly out of a greedy desire to live up to Tony's expectations, eventually facing his own inadequacies. Even after Tony took his suit away, he chose to save people, realizing that he is Spider-Man not because of the technology, but because he is a hero. Afterwards, Tony came to cherish Peter, and they shared a father-son relationship. During the Battle of Titan, as Peter was disappearing due to Thanos's snap, he leaned on Tony, showing fear and confusion; his death left Tony with deep guilt. After returning, Peter reunited with Tony in the final battle, only to witness the sacrifice of the mentor and father figure who had guided him. Following Tony's death, Peter felt burdened by the expectations and responsibilities left to him and wished to return to being an ordinary student. However, during a trip to Europe, he got caught up in the Mysterio incident. Inheriting Tony's legacy, E.D.I.T.H., Peter questioned if he could handle such responsibility. Believing Mysterio was a true hero and wanting to escape the pressure, he handed E.D.I.T.H. over to him. After discovering the betrayal, he broke down but rose again through Happy, realizing that what Tony believed in was Peter himself. However, due to the exposure left by Mysterio, Peter's identity was revealed to the world, and he lost even his ordinary life. To protect his friends' futures, Peter asked Doctor Strange for help, encountering villains from other worlds in the process. Initially intending to send them back, he remembered Aunt May's teachings and chose to save them instead of sending them to their deaths. However, that choice turned tragic because of the Green Goblin, and May died trying to protect Peter. May's final lesson left Peter with great pain and responsibility, and he collapsed. Consumed by revenge, Peter met MJ, Ned, and Spider-Men from other worlds, hearing the stories of those who suffered losses like his own. He regained his resolve, choosing salvation over hatred even when faced with the chance to kill the Goblin, accepting the meaning of responsibility he had learned. To stop the collapse of the multiverse, he chose the sacrifice of making everyone forget Peter Parker. After vanishing from everyone's memories, Peter let go of MJ, Ned, and all the relationships he loved to start a new life alone. Though he lives with the loneliness of losing his loved ones, he remains New York's Friendly Neighborhood Spider-Man, ignoring his own sorrow and throwing himself lonely into his hero work.
