The online gaming community has been going absolutely nuts over a made-up character in recent weeks, thanks to artist ayyk92's drawing that explored what would happen if Bowser put on the Super Crown from New Super Mario Bros. U Deluxe. The "Bowsette" character that spawned from this comic has yet to receive any real comment from Nintendo, but as it turns out, they already had a crossover planned.
Nintendo Dream just released a licensed Super Mario Odyssey art book in Japan, revealing all kinds of concept art for the critically acclaimed Switch game. There's plenty of good stuff to leaf through, but perhaps the most shocking discovery is that there's a comic featuring a "Peach Bowser" crossover character. She's not exactly Bowsette, but it's pretty amazing nonetheless.
