Legend of Zelda has a bunch, obvious you mentioned Ganondorf but all the Gerudo have brown skin! They're not all enemies or villains in Breath of the Wild, they're just regular people.

There's the guy that trains you in Punch Out (besides Mike Tyson lol).

I'm sure there's some non Asian POC representation in street fighter or whatever, but I didn't play a lot of fighters.

There definitely isn't a lot though and even when you could customize your main character (like in Animal Crossing) they didn't do the best in representation either until, like, this decade.

It really is just white and Japanese for almost every property. You can consider Splatoon an exception, but well, Splatoon's aesthetic of awkwardly appropriated black culture doesn't make that feel like a point in Ninty's favor.

Legend of Zelda has the Gerudo, which are portrayed in varying degrees from problematic to quaint depending on the title.

The one, the only, the GOAT, Mike Tyson in "Mike Tyson's Punch Out"

Mike Tyson's Punch-Out!! Around the time the Gold Version was released for a NES Open Tournament Golf competition,[19] Nintendo of America's founder and former president Minoru Arakawa attended a boxing match during the Heavyweight unification series that featured its future champion Mike Tyson. Arakawa became so astonished with the athlete's "power and skill" that he was inspired to use his likeness and the tournament itself in the upcoming game.[20] Tyson was rumored to have been paid $50,000 for a three-year period for his likeness. This transaction was something of a risk for Nintendo, as it occurred before Tyson won the World Boxing Council (WBC) heavyweight championship from Trevor Berbick on November 22, 1986, which greatly increased the profit for the game.[21] Nintendo re-released Punch-Out!! in Japan.

Everyone is forgetting about Pikmin smh

Xenoblade's decent about this. The games have Taion, Sena, Elma, and Vandham all as playable characters, even not delving into NPCs.

Ensemble style games sometimes do, like ARMS or F-Zero. But if you want racial diversity, Nintendo is only going to let you down.

Kirby is pink

Little mac from a 15 year old gane at most recent i think?

Fire Emblem has a POC character or two every game. It's a coinflip as to whether the character in question is a racist caricature however.

In SSBU, Inkling and Villager have non-white alt costumes. And I think those are options in their original games as well.

Fire Emblem: Three Houses has Dedue and Claude, who look to have a little melanin.

You mentioned the Gerudo, but yeah I think that's probably it.
