What if that Sora, Donald, and Goofy visited the world filled with zombies in the MCU but as the alternate reality of it, they will have to do nothing but survive the zombie pandemic with the other super people to help fight against the zombie army and help them find a cure the save everyone. But that is just if they ever got themselves into a zombie apocalyptic reality of the MCU maybe even created by Hades or Dr. Doom or Thanos just to mess with the Keyblade wielders, Mickey's captain of the royal guard/wizard, and the other heroes just to make sure they have to find a way to escape that reality and back to the MCU version of it. Don't you think that would be so messed up if they ever did?
