I´ve seen people complaining that Nintendo doesn´t put black characters in their games, my question is, have they played or seen Sword and Shield? Your rival, the champion and the most popular gym leader are black.
Pokemon is really the only Nintendo game with some amount of black representation, and even that took a long ass time (wasn't the first black gym leader not until gen 5?) and still isn't incredible. Sword and Shield seems like it went in the right direction (although I think Hop + Leon are supposed to be Desi) by adding in better black/brown rep. But even still, that's such a small amount of representation for an incredibly global franchise.
Fire Emblem has some POC coded characters, but a lot of times their stories boil down to being about their skin tone/'otherness' in a way that I feel like is probably really exhausting when that's what 99% of their character arcs are.
Overall Nintendo has a huge problem with representing POC, particularly darker skinned POC. Hell, in Animal Crossing for the 3DS, you couldn't be anything other than pasty unless you went to the beach to tan every day in the summer--a game that's supposed to let
you feel like you're living there.
It's really disingenuous imo to point to a few examples and say Nintendo has done their part.
