History
Mary Parker was born to Peter and Gwen Parker in a universe where her father never became Spider-Man and her both her mother Gwen, grandfather George Stacy and granduncle Ben Parker never died.
On one autumn day at the World Trade Center, Mary was with her entire family to celebrate her father’s promotion to Vice-CEO of Powerchip when the WTC tower opposite to theirs was rocked by an explosion.
Her father, having been accidentally taken control of by Earth-616’s Peter Parker due to an imbalance in the Nexus of All Realities, left her and her mother to go change into Spider-Man but ended up falling to his death, which propelled Earth-616’s Peter Parker back to his own body. Believing what he saw to be nothing more than a dream at first.
