His name is Y/N Stone. He was adopted by May and Ben Parker when he was just five years old after his parents abandoned him. At the same time, a six year old Peter Parker was adopted by them as well. Peter's parents, Richard and Mary were forced to drop him off at his aunt and uncle's home. As years went by, Y/N learned that his parents had abandoned him for adoption and decided to change his last name to Parker as well, since they were the only ones who treated Y/N with respect and the love he deserved. Peter gets bitten by a radioactive spider, which gives him special powers. And right after that...Uncle Ben gets killed, making Peter assume the persona known as Spider-Man. Some years later, Y/N also gets bitten by a radioactive spider, giving him strange spider-like powers, but the same day this happened, Peter Parker, the Spider-Man was having a battle with his worst enemies. During the battle, Peter and Green Goblin engage in a final confrontation, resulting in Peter taking a fatal blow. He dies in the arms of his loved ones, leaving behind a legacy that inspired a new generation of heroes. After Peter's death, the mantle of Spider-Man is taken up by Y/N, who becomes the new Spider-Man after making a promise to Peter. About some years later, a seventeen year old Y/N was sucked into another universe. There, he meets lots of other spider people: Miles, Peter B. Parker, Peter Noir, Peni Parker, Peter Porker and of course...Gwen Stacy
