If you’re wondering like I was:

King - Mario and Bowser

Queen - Luigi and Bowser Jr.

Bishops - Peach/Daisy and Magikoopas

Knights - Yoshis and Birdos

Rooks - Toads and Goombas

Pawns - Coins and Koopa Shells

I feel like toads and goombas should have been pawns. Thwomp is the perfect rook. I can’t think of a suitable replacement for the Mushroom Kingdom’s rook other than stylizing it like Peach’s castle.

I always thought Mario and Luigi should have been the knights. You know, the only pieces that can jump.

It makes sense. There are two of them, and only one Luigi. There needs to be two bishops, and one queen.

I mean… They’re both princesses after all, not queens…

Slay, queen.
