Powser

Powser is the het ship between Princess Peach and Bowser from the Super Mario fandom (and additionally from the Super Smash Bros. fandom).

Canon


Bowser has repeatedly kidnapped Peach and invaded her kingdom, both out of a megalomaniac desire to rule the world, but also because he has fallen in love with her.

Fanon
Powser is actually one of the most popular ships for Bowser. It rivals with Mareach as both Mario and Bowser are portrayed in a struggle over Peach.

Powser fans headcanon that Bowser kidnaps Peach either because he wants her to bake a cake for him, or because his kids (Bowser Jr. and the Koopalings) desperately want a mother.
