If you’ve ever stared at one of The Legend of Zelda: Breath of the Wild’s random villagers and thought, “Hey, that looks like a Mii,” it could be because the two might be related.
I’ve never really cared too much about Miis. I never even made one for my Wii or 3DS — hell, I’ve never even opened Street Pass. The only reason I made a Mii for my Wii U was because it was part of making an online account.
