*Bowsette, also known as Princess Bowser, Princess Koopa, and Peachser, is Bowser under the effects of the Super Crown, sometimes explained as a modified version of such created by Kamek. In this form, Princess Bowser gets additional mobility in the air, such as a double jump and glide, as well as a boost out from pits. She is also able to utilize her flame breath.

Whether this is simply a power-up or a new identity for the former Koopa King tends to vary from story to story.

Bowsette resembles Princess Peach, but she has Bowser's horns and ponytail hair. Her hair color is either red with blond highlights or straight up Peach's blonde. She wears a black version of Peach's attire with no straps similar to her wedding gown and has many spiky collars. She has Bowser's shell and tail, inheriting them from her past form.

In HammerBro101 Incorporated's games such as Koopa Kart 8, she has a black dress with gray flannels, red lipstick, red eyes, and Peach's crown instead of the Super Crown (because it didn't exist yet at the time Koopa Kart 8 came out), but otherwise resembles Peach with Bowser's tail, horns, spiky teeth, and spiky tail.

Bowsette possesses the powers of the Super Crown, which allow her to double jump, glide, and jump out of pits. In addition to this, she is also able to breathe fire as she used to as the Koopa King. It's likely she can also grow in size and has her brute strength retained, as well as being able to throw hammers.*
