Much in the same way that Avengers: Infinity War and Endgame were a two-part culmination ofof a decade of MCU canon up to that point, the back-to-back climax of Avengers: Doomsday and Secret Wars is about to call forth a whole lot of disparate strands from the last 6 years. The Disney+ series Loki broke time and space by unleashing the Multiverse, creating a massive existential threat in the form of apocalyptic universal collisions named incursions and also serving as the ripple effect driving the larger narrative of the MCU’s aptly titled “Multiverse Saga.” We've been reacquainted with familiar alternate Wall-Crawlers, crowned a new Black Panther and met the Atlanteans, played catch-up with the Fox X-Men universe, and sat down for dinner with the Fantastic Four of a parallel Earth – and somehow Doomsday is going to wrangle all that together in just four months.
Now the recently released Spider-Man: Brand New Day has added even more complications to a multiverse on the brink of catastrophe. The biggest, of course, is the introduction of the X-Men’s Jean Grey, the first member of Xavier’s first class to show up as an Earth-616 (the MCU’s “official” universal designation) native. And while the flashing neon sign saying “the X-Men are here (or maybe not?)” is sure to dominate the conversation surrounding the film, the post-credits scene adds an interesting Doomsday-related wrinkle to the discussion, one that might have less to do with the MCU’s Spidey than it does with one of his alternate variants.
