Earlier today Pokémon Bank became available for Pokémon Sun and Moon, meaning trainers can now transfer Pokémon from gen 1 through to 6 to the latest titles. It also appears that the experiments have started, and one in particular includes the glitch Pokémon MissingNo.
Twitter user @Blazevoir has found out that once you transfer MissingNo. to Sun and Moon, Pokémon in the same box will have their names shifted over by one. Here are some images showing what happens below:
Along with this, YouTube user Clyde BlueSnake has uploaded a video clip demonstrating the glitch:
Transferring this Pokémon over to Sun and Moon could also cause other problems that haven’t been discovered yet, so it isn’t recommended, but it is interesting to see how it appears and also how it changes things around in the new titles.
