The John-Verse is a rare separate Multiverse with countless of John AU's. We have, John Fallout from Fallout, John Halo from Halo, John Helldiver from Helldivers, John Doom from Doom, John Ultrakill from Ultrakill, John Metal Slug from Metal slug, and many, many, many more. If a John meets another John, they would become best pals and maybe, just maybe take over the multiverse. Every John's first name is John, their last name is based on the video game universe they are from.
