Spider-Girl is a character that appears in LEGO Spider-Man: The Videogame.
May "Mayday" Parker is the first child of Peter and Mary Jane Parker in a future, alternate universe. Peter and Mary Jane were reunited with their baby daughter by Kaine, who found the child living with Alison Mongrain, the con artist who had kidnapped the baby on instruction from the Green Goblin. After they were reunited, Peter lost a leg during the horrific battle with the Green Goblin. After the battle, Peter was offered a bionic replacement from Mr. Fantastic, and considering it a wake-up call, decided to retire and focus on being a husband and father.For years, they chose to keep their past from Mayday and hoped that she wouldn't develop powers of her own like her father.
Despite her parents' hopes, May began developing versions of her father's Spider-powers when she was fifteen. At the same time, Normie Osborn (Green Goblin's grandson) set out to restore the family name (as he saw it). Mayday donned Ben Reilly's Spider-Man costume to stop him and soon took to crime fighting, at first hindered, then helped, by her worried parents.
May shares traits of both of her parents. Like her mother, she is beautiful, charismatic and popular student, and she is intelligent and bright, just as her father was. She also inherited his love for in-fight bantering. In addition, she is a very good athlete and excelled in her girls' basketball team until she quit after her powers emerged. On the other hand, May seems to have inherited the "Parker luck" in which her dual identity wreaks havoc in her private life.
