Sadie Sink is reportedly set to play daughter of Tobey Maguire's Peter Parker, Mayday Parker, in the upcoming 'Spider-Man: Brand New Day' movie. The film might further play with the multiverse concept, leading the characters directly into 'Avengers: Secret Wars'. In the comics, Mayday gains her powers after Spider-Man loses a leg and retires from crime-fighting in alternate universe reality-982.
