PonPon

PonPon is Jon after using the Super Crown from New Super Mario Bros. U Deluxe.

Origin
During the Bowsette trend after the announcement of New Super Mario Bros. U Deluxe, AriZonia decided to do it to Jon. Rather then being a Peach version of Jon, like most depictions of characters using the Super Crown, she was essentially a female Jon in a princess dress. Down the line, she became a succubus and is often depicted with wings.

The name "PonPon" was originally derived as a shorthand version of "Peach Jon", and was the alternative to calling her "Peachathan". The addition of the second "Pon" was to make the name sound better, and is a reference to the song "PonPonPon" by Kyary Pamyu Pamyu.

Her design was originally based on Jon playing Waluigi in the Mario Party games after his addition in Mario Party 3, which was the origin of her having long, pointed ears. After October of 2018, where she became a more consistent character, Ari established her to be a succubus, gaining her heart-tipped tail. She originally had bat-like wings, but they were swapped out for the ethereal, magenta colored, ones she's known for now, as a reference to PJ's wings in the Maids RPG campaign Ari had played in. These wings are able to be hidden, as they do not have a physical form, but do still work regardless.

Lore
Originally Jon when trying on the Super Crown; PonPon became her own entity after absorbing enough energy from the crowns and causing the "Glitch Bang" that would create the Jonaverse. In the process she has also become a succubus. As in her demon nature, she often teases Jon and the other alternate versions of herself. She means well though.....most of the time.

After the "Glitch Bang", PonPon seems to retain her ability to change size at will. Typically she remains at a height slightly shorter than the original Jon, which the remainder of the difference being compensated by heeled shoes, or flight.

The appearance of her right eye is typically left unknown, but in July of 2019, it appeared that she has some sort of scar on the right side of her face, and the space where her right eye should be was nothing but void. In addition she had an ability to turn one-shot Alt Jons into cookies she consumed to keep her powers in check. These was never touched upon again.

Trivia

 * PonPon is the Alt-Jon that caused the Jonaverse to happen.
 * PonPon is the first main Alt-Jon after Electron Jen.
 * If the gender-bent version of the name Jon, Jen, does not count, PonPon is the first Alt-Jon to not have "Jon" as part of her name. However, her name is still a contraction of "Peach" and "Jon", so this remains up for debate for if it counts.
