First Appearance: The Amazing Spider-Man #25 (June 1965)

Mary Jane Watson, also known as MJ, is a fictional character appearing in American comic books published by Marvel Comics. She is the most famous and prominent love interest of Peter Parker, also known as Spider-Man. MJ was created by Stan Lee and John Romita Sr., and made her first appearance in The Amazing Spider-Man #25 (June 1965). She was initially set up by Aunt May as a blind date for Peter, but they broke it off as Peter saw her flamboyance and 'life of the party' personality as shallow. After Gwen Stacy's death at the hands of the Green Goblin, MJ became Peter's main love interest. The pair formed a bond, as Mary Jane became a more open-hearted person. They got closer, fell deeply in love, had an on-off relationship for years and eventually married. Despite their marriage being undone due to the timeline manipulations by the villain Mephisto, Mary Jane and Peter retained a close friendship. They later resumed their romantic relationship for some time and are destined to have a daughter Mayday Parker / Spider-Girl that will end Mephisto's eventual reign over the Earth, whom Mephisto sought to erase from reality
