I love Pokémon, it's my special interest, I've been playing since Gen 1 and have pretty extensive knowledge about the Pokémon world.
However since becoming a communist I've realized that a lot of things are missing from the world, including basic functions on how everything works. Just the presence of police implies there are laws that have to be enforced, which in turn implies people write those laws, etc. We know that there was an industrial revolution, which led to capitalism, being the economic system in all Pokémon regions, meaning all of the contradictions that come with it. There was a war that took place, as alluded to by Lt. Surge, who might actually be from Unova.
In the manga there's the Pokémon Association (PA), a legislative body that determines the laws involving Pokémon, similar to Congress here in the U.S., with each region apparently having its own PA.
In the anime they have the Pokémon Inspection Agency (PIA) that inspects Gyms to see if they're up to par.
They don't explicitly talk about politics and political views (obviously because the series is marketed to kids) but I think exploring these mechanisms could be really interesting, if not for the fact that Pokémon adds another layer to politics because they're creatures with a material effect on the world.
Some people might be more left leaning when it comes to economics and social issues, but might be more right leaning when it comes to trainer regulations.
I'm curious to know what other people think, I'm actually writing a story that explores some of these themes so I'd love to get some ideas!
Have you looked into the modding scene much? I think there's a lot of fan content that explores different aspects of the world. Though I can't say I've played much of them myself.
