Post Jeffy's Bad Word, she only abuses Mario whenever he doesn’t stay out of her way or when he abuses Jeffy. Since Logan is now family friendly, Rosalina doesn’t abuse Mario anymore as of now, she just sometimes yells at him when he acts greedy or cruel. Big Red • Kung Pow • Baby Peach • Taco Bell Chihuahua • Mama Luigi • Speedy • Pimpster Goomba • Skittles • Shrek Junior • Taliban • Blue • Chad • King Pig • Ray the Pig • Helmet Pig • Yoshi • Koopa Troopa • Atso • Brown Elephant • Lazlo • Mr. Pig • Peach • Tony the Tiger • Woody • Mr. Magoo • Luigi • Donkey Kong As of now, her age group has never been revealed but it can be assumed she is around the same age as the Mario Bros and Peach.

The only time Rosalina gets frustrated with Jeffy was in Jeffy Gets Potty Trained! when she forced him to eat his peas, but Jeffy demanded marshmallows instead. She also sometimes gets mad at him in recent videos. And in Jeffy's first apperance ( Mario the Babysitter!) she did not like Jeffy and was even a little scared of him. Due to the fact she was attracted to Atso's body in " Shrek's Coma!" she is show to have pedophilia urges Rosalina is presumed to have some pedophiliac tendencies, as shown in Shrek's Coma!, where she was shown to have found Shrek in the body of Atso, a second grader, to be sexy. Rosalina has held a grudge against her since Jeffy's Parents! She can't stand her beating up Jeffy. When Jeffy gets taken away, she got frustrated with Mario, yelling that she can't believe he let Nancy take him away, trying to convince him that Nancy beats Jeffy, but Mario shows absolutely no concern, even stating that it's good that she beats him, leading Rosalina to break up with Mario for his heartlessness, albeit temporarily. She resents the woman. Ironically, Rosalina hasn't appeared in recent videos recently likely due to the pandemic. The reason is the same as to why Pablo is using his characters on face time or not appearing at all, that Elaina didn't want to get the coronavirus, although she, alongside most of the cast and crew (save for Pablo) wound up getting it in November 2020. However, despite that, Elaina still filmed scenes as Rosalina and Karen despite having coronavirus at that time.Her vegetarianism was possibly undone in Jeffy's Switcheroo!, meaning she likely was on a diet and couldn't eat meat until than. Yet Rabbid Rosalina is also aspirational. Despite her fatigue, she’s still showing up – and getting the job done better than any of her opponents. “When she's called to action, she just reacts like, ‘OK, must I, sure, do I have to?’,” Nava says. “But then, when she's on the battlefield, she’s really super powerful. She’s brave. And she’s a fighter.” It's also possible she is lying about being vegan if you go by the theory above that she is playing dumb on Mario and Jeffy. She is the only member of Mario's current family not to have met Luigi depending on if the Luigi's Mansion series is canon.

In Jeffy's 16th Birthday she briefly mentions about 3 other ex's she's had which are a rapper, an archaeologist, & an astronaut. Rosalina appears the same as she does in numerous Mario games, having a long cyan gown, platinum blonde hair with a side bang that covers one of her eyes and cyan eyes. There have been times where Mario would argue, but these arguments mostly have been caused by Jeffy. In Mario's New Hat!, the two's wedding day has finally arrived. Though she almost calls it off when Mario mysteriously disappears. Once Mario finally shows up as a Frog and explains what happened, Rosalina declares that she doesn't care what he looks like, and she loves him for him. Goodman (after comically warning Mario that she'll take everything he owns because she didn't sign the prenup) makes them take their vows and they finally get married, with their kiss breaking the spell over Mario. She can get defensive of Jeffy to the point that she ruined her own husband's reputation, claiming to the police that Mario likes to beat Jeffy up all the time, which is not factual.For a while, the teams weren’t sure they could pull it off. “Now I’m confident it’s working, and it brings so much dynamism to the battlefield, and allows for so many possibilities: strategic ones, tactical ones, creation of combos and synergies between the heroes,” Nava says. “It’s really an improvement towards making the genre appealing to an even wider audience.” In Smart Jeffy, Junior caught Rosalina's attention by calling her "Busty Tits" and Junior explaining to her what happened to Jeffy.
