The Spider of Republic City

Summary: During their marriage, Mary Jane and Peter had a son named Benjamin "Benjy" Parker a year after their first child miscarried. The two would raise their son with all the love and care in the world for the next seven years.

However, after Aunt May was shot during the first Civil War, Mary Jane and Peter Parker were approached by Mephisto. The Lord of Hell offered to save May's life in exchange for little Ben's soul, since the Parker scion is destined to defeat him in the future. But they refused, and an angered Mephisto erased everyone's memories of Benjy and tried to claim the boy's soul. Fortunately, an outside force interfered and sent Benjy to another dimension. Now, at age 16, Benjy must find a way back home, all while protecting Republic City as Spider-Man.
