I really like the character designs for SwSh so far. Galar is the first cooler region that we've gotten since Kalos, since Hoenn and Alola were both island/tropical regions and Kanto is just kinda... temperate? I don't know; Kanto has never felt like it had much of a climate identity, but everyone seems to be happy in shorts. As such, it makes sense that people are a little more bundled than they would have been in Alola, especially. While I feel like the games have always done well in fitting the player character's wardrobe to the location, these last couple of generations have really done a great job in designing the full cast for the region. The internet (me included) seems to think every new character (well, maybe with the exception being the professor and her assistant) will be the evil mastermind of the game, which just tells me that they all seem interesting. We want to learn more about how all of these people will fit together, which seems like a marked improvement from some entries in the franchise where the characters just seem to exist for some reason.
I love that Team Yell was real, and their grunts seem like they'll be satisfying punching bags. Being soccer hooligans just sounds so British to me, but I find the toxic fanbase connection people almost instantly made even funnier. I think they'll end up being somewhat sympathetic thugs like Team Skull. Hopefully they'll have a similar charm with their mannerisms and music as Skull did, but it seems promising so far! The fact that they show up in the background when we battle Marnie is a great touch to further show their devotion.
