Major spoilers below for the end of Spider-Man: Brand New Day and its post-credits scene, so be warned if you haven't already watched it!
By the end of Spider Man: Brand New Day, Tom Holland's Peter Parker is seemingly set to usurp the magical power of Doctor Strange's No Way Home spell with the power of friendship, after helping set up the future of MCU's mutant population, and giving Jon Bernthal's Frank Castle a lot of bullets to scatter. But it's that post-credits scene that we're here to talk about, because what a nutty way to set up a connection between this movie and...probably the upcoming Marvel movie Avengers: Secret Wars, but maybe also Doomsday?
