History: In a not-too-distant possible future, Peter Parker retired his Spider-Man career to live a normal life with his wife and daughter. His daughter, May grows up to become a very athletic and agile varsity basketball player. While watching young May during a game, Peter and Mary Jane noticed that their daughter exhibits what they considered to be superhuman agility and skill. Dismissing the whole things as a fluke, Peter and Mary Jane decided to keep the whole situation under wraps - until - the mysterious Green Goblin seemingly returned from the grave and cornered May. Terrified, May went home and told her parents of the incident. Vowing to meet the Green Goblin at the Brooklyn Bridge at midnight - Peter took off for a final showdown with the Green Goblin. Scared for her husband's life, Mary Jane revealed to May that her father was Spider-Man ... and that she too inherited some of his abilities. Donning a spare Spider-Man costume, May entered the fracas as Spider-Girl ... saving her father's life ... and thus began the costumed career of the stunning Spider-Girl.
