Boob Timelines

The boob timelines refer to three major times Jon has been genderbent, resulting in an Alt-Jon's creation:


 * 1) Electron Jen, in July 2011
 * 2) PonPon, in September 2018
 * 3) RosaJon, in February 2019

Electron Jen: The Beginning
Some time after The Runaway Guys first formed, fans made gender-bent versions of the trio called "The Runaway Girls". Using the pseudonym Jon uses for his sister, Emile dubbed Jon's genderbend Electron Jen. The earliest interpretations for this character came about from AnnabethRide (whose art is the determining factor for her birthday) and Holleit (seen above). The latter, who was Jon's girlfriend at the time, got it printed and framed by someone she knew who did framing and hid it behind Jon's diploma in his office. The image was also posted to Deviantart.

The term Alt-Jon did not exist when she was first conceived (nor did Jon or anybody saw an entire Jonaverse coming). The modern design of Electron Jen was made by ChaozAgent, including her 2023 redesign, aiming to keep the spirit of the de-facto oldest Alt-Jon alive. With electric powers and a baseball bat, she's often portrayed as aggressive and can strike at a moment's notice...

PonPon: the Super Crown's effect on Jon
The succubus PonPon came about due to the Super Crown's introduction, a Toadette-exclusive powerup in New Super Mario Bros. U Deluxe (2018). AriZonia created her simply as a Jon with a princess dress, breaking the trope of the Super Crown turning the user into a version of Peach (like Bowsette and Booette). Despite that, her name was originally made to be shorthand for PeachJon-PeachJon, but perhaps to discern her from the alt of the same name, Jon says her name is shorthand for Princess Jon-Princess Jon.

Despite being a joke made for a drawing challenge prompt, PonPon's popularity has always been moderate, especially being the trope source for the term Alt-Jon. However, a few months later...

RosaJon: "The Great Inflate"
...Jon opened his mouth during a Game Clearing stream of Bengai-O in 2019 (the theme was games that began with each letter of the alphabet). Specifically, he said if he was a girl, his boobs would be noticeably big.

This was Jon's response to being drawn as space princess Rosalina, in response from him being bummed from losing in a Smash Bros. tournament. Thus, RosaJon was created. And her bosom kept getting bigger, as his reactions for being drawn too "small" were, "Not busty enough," and, "could be bigger."

Whether it be for her curves or the many interpretations of her, Rosa has been a very popular muse for Jon's artist community. She is usually characterized similarly to Jon's demeanor (glitches and all), as contrasted by (but not devoid of) the motherly figure Rosalina may be portrayed with. Some artists, if they're into it, draw her boobs ENORMOUSLY, while some are [way] more modest about it. Regardless, to avoid Jon's Twitter getting too spicy with busty genderbent drawings of him, The Booru was made later that month and the original intermission block, Twitter Time, was scrapped completely besides that one time the Booru was down and he had to show Twitter posts for one intermission. (Jon still retweets SFW fanart of her on Twitter, of course.)

RosaJon is what ultimately sparked Jon's artist community as we know it today. While Rosa has become the most prominent and popular alt since "The Great Inflate" and has been given multiple designs, by no means are people limited to drawing only her. Jon is a very vocal advocate for people making art and improving their craft; no matter where they are in the process or what they do, he is very happy to see people make art of any kind and see them grow. Many of Jon's fans echo Jon's appreciation and advocacy of the arts, and tons of artist of varied experience have come out of the woodwork ever since.

Rosa is also officially the first alt Jon has cosplayed as in a full crossplay (boobs and all). He made it an incentive for him to cosplay as Rosa for TRG Colosseum 2022 if an incentive was met during a BCRF stream in October of the previous year (obviously, people made that happen). Even before this, Rosa made an appearance as a custom Soul Calibur VI character made by Jewker for TRG Colo 2019 among other prominent alts of the time. He also makes cameos as Rosa in certain TRG Colo bumpers and as gags in other TRG friends' videso. As a result, Jon and RosaJon have always been linked in the grand scheme of the greater TRG sphere and community/fanbase.
