What are some of your headcanons?
I'll start
- Red's favorite color is blue
- All Pokémon regions are countries and have their own governments (that aren't shown in game for obvious reasons) and the Pokémon World is likely geographically different (only reason to think it's similar is the Geonet but I don't think that's entirely canon and only exists as a way of connecting real world to the game.)
- Adolf Hitler gassed the Jews with Koffing and Weezing before incinerating the bodies with Ninetales and Arcanine.
