Bowsette, or Koopa-hime (Japanese: クッパ姫, translit. Kuppa-hime, lit. 'Princess Koopa'), is a fan-made, gender-bent version of the Mario franchise character Bowser, in which he is transformed to resemble the character Princess Peach using a power-up. The character was created on September 19, 2018 by an artist named Ayyk92 as part of a comic strip which he posted online. Bowsette quickly rose in popularity internationally, with related hashtags in English and Japanese trending on Twitter. Typically portrayed as a light-skinned blonde woman with horns, fangs, and a spiked collar with matching armbands, several professional Japanese artists contributed their own renditions of the character. A convention themed around Bowsette was planned for October of the same year.
