RosaJon

On February 3rd, 2019, Jumney posted a drawing of Jon dressed as Rosalina during a Twitter art block on stream, to which Jon said, “Not busty enough“. He was referring to the fact that he’d be larger as a girl to reflect his own body. Jon’s fans went along with the gag to becoming his most prominent Alt-Jon, as well as taking Rosalina into Jon’s brand along.

The creation of Rosajon has made large boobs a recurring joke on Jon’s streams with any female character. The word “bigger” has also been associated with the situation as a response to any madness. Rosajon is considered to be quite powerful as Rosalina is normally. RosaJon also created the trend of Bagel joining as LumaBagel and changing species along with Jon and Rosajon.

Rosajon has also sparked the idea of merch to be sold by Jon. The community has had fun making original designs to distance Rosajon from Rosalina, from glasses, bras, leggings, mousepads, and even a space magic-enhanced hoodie. This was done primarily to give Rosajon her own identity, and other alts who were inspired by other IPs eventually followed suit. At least for the time being, her hoodie had been on sale as real merch (sans space magic) and the Black Hole Chaos Jonaverse Fanzine featured her and some other prominent alts.

One of the often-seen alternates; RosaJon frequents Jon's streams quite often. The Galaxy Princess is sometimes accompanied by a Luma missing one eye named Bagel. She has some manner of shapeshifting abilities as no one has a clear consensus on the size of her "gravitational orbits", so-to-speak. Beyond that, she also seems to come under quite a few different looks that are seemingly tied to what Jon may stream in an evening; her default look is the original Rosalina's attire of a silver crown, a long-sleeved turquoise gown that bares her shoulders (and very impressive cleavage), golden star-shaped earrings, and silver high heels.

As RosaJon has been controlling more of her powers, there also seems to be occasional glitches that follow her. At times blinking just at the ends of her hair.

RosaJon is straight/heterosexual since Jon/Claire is the closest in personality to Rosa. However. she could also be considered bisexual depending on what version of Lucahjin she is paired with.
