Bowsette, or Koopa-hime (Japanese: クッパ姫, translit. Kuppa-hime, lit. ‘Princess Koopa’), is created when Bowser 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. Bowsette is 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.
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. 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.
