Bowsette became a popular meme in September 2018 being an anthropomorphized gender swapped Bowser. In a new trailer for a new Super Mario Bros game for the Switch was released, it included the Super Crown, an ability by Toadette, which allowed her to turn herself into Peachette.
It didn’t take long for the imagination of the Super Mario fanbase to come up with a hypothetical situation where the Super Crown was given to Bowser – turning him into Bowsette.
Bowsette then took the internet by storm. Within days of the initial Bowsette comic strip release, hundreds of Bowsette memes began popping up and filling the internet.
And from there more and more Bowsette memes and fan art spin-offs started taking over.
