Bowsette

Bowsette () is a fan-made, moe anthropomorphized and gender-swapped version of the Mario franchise character Bowser, in which he is transformed by the Super Crown power-up to resemble the franchise character Princess Peach. The character was originally created on 19 September 2018 by Ayyk92, a Malaysian online artist, as part of a comic strip which he posted to Twitter. Bowsette subsequently became an Internet meme and rose in popularity internationally, with related hashtags in English and Japanese trending on Twitter; several professional Japanese artists contributed their own renditions of the character on the website, referring to the character as Princess Koopa ().

Bowsette is typically portrayed as a blonde woman with horns, fangs, a spiked collar with matching armbands and a black strapless dress, essentially combining Princess Peach with elements of Bowser's appearance. Journalists took notice of the trend and were surprised by its longevity, attributing it to various aspects such as the character's appearance and appeal or the possible desire by fans to shock Nintendo's social media handlers. While some noted much of the art that spawned from it was solely pornographic, others were quick to emphasize that some had a wholesome tone instead. Bowsette's rapid popularity led to other fan-made characters in a similar vein in a short timespan, each based on an existing Nintendo character. In Japan, concerns were raised about the legality of fan-made characters under Japan's copyright law.
