>>48658711>. In fact I think the SINGLE time it is mentioned in that game is in reference to the Black Belt that owns the restaurant and was officially shown to be a recurring character in Gen 2's Mt. Mortar.Someone was claiming this yesterday too, so I tallied up the numbers. XY mentions Kanto 6 times (although one is the guy foreshadowing Alola who mentions all five regions) and SS mentions Kanto 5 times. Platnium mentions Kanto around 8 times (13 if you count the Pal Park dialog where they stuff like "you can send Pokemon from Hoenn or Kanto").
Alola mentions Kanto by name 33 times, almost all dialog of NPCs saying stuff like "so, you moved here from Kanto?" or references to the original forms of Alolan Pokemon.
