Rosalina first appeared in the American Idol reboot series, but she wasn't properly introduced until the video, " Mario's New Girlfriend!", where she and Mario fell in love and started dating.

As of 2021. Rosalina is only rarely frustrated with Jeffy. She even likes to join in on Jeffy's abusive behavior towards Mario and others. 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.

However, in her recent appearances since the introduction of Jeffy, her relationship/marriage with Mario escalated into a female-on-male abusive relationship with Rosalina as the perpetrator. Rosalina truly loves Mario and has a strong bond with him. He's Rosalina's husband. She is mostly seen hanging out with him. She also takes care of Jeffy with Mario as a parental guardian. Nowadays, Rosalina rarely gets really irritated with him being mean to Jeffy, though. She also tends to cheat on Mario. 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.

However, she has consumed foods containing animal products in the past, so either she became one afterwards, it may just be a crutch to make her feel better about herself, or she may be flexitarian.

In a Meet The Cast video for her voice actress Elaina, a puppet version of her has been revealed alongside Bully Bill which her puppet looks more tomboyish. Rosalina is the only female character to be a main character, even though she doesn’t appear normally.

There were also times when Rosalina was theorized to have broken up with Mario, but they remain together to this day. She absolutely hates having a ton of money (possibly because she knows it corrupts people and turns them into selfish jerks, examples including Junior, Joseph, and Mr. Goodman) and forces this view on Mario; she believes that people have jobs for fun. This is especially prominent in Mario Sells Jeffy! where she bearded Mario for selling Jeffy for 10 million dollars. She would only spend some time with Mario and her annoying son Jeffy and tells Mario most of the time to control his anger. As of 2020, she acts more antagonistic and her personality has become more whiny, cruel, insensitive, unintelligent, cranky, and spoiled. She is also incredibly hypocritical, as she openly flirts with her many ex-boyfriends and dismisses Mario's complaints as him being jealous, while constantly accusing Mario of cheating on her and once trying to kill him just for texting Peach. Her hypocritical side is also shown in " Goodman's New Life!," where she verbally abuses and puts down her husband so many times, but when Marvin (unknowingly to her Goodman) called her fat once, she decides to file for divorce. Her overall disposition also implies that she has come to hate Mario for not catering to her whims and may only be staying with him for Jeffy's sake (or possibly his money).

In the same episode, she is revealed to have an evil and torturous side, as she terrifies Mario just for lying to her. This revealed that Rosalina can also be hypocritical, as she criticized Mario for lying, even though Rosalina lied to the police that Mario likes to beat Jeffy all the time. 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.”Her vegetarianism was possibly undone in Jeffy's Switcheroo!, meaning she likely was on a diet and couldn't eat meat until than. 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.

There have been times where Mario would argue, but these arguments mostly have been caused by Jeffy.

Another possibility is that the videos where she is vegan are set in the human puppet universe while the main universe Rosalina has a normal diet. Rosalina's ex-boyfriend that Mario got jealous over. D-Money broke up with her since she was being dragged along with him too much. Her parents had preferred her dating him instead of Mario. 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.

In Jeffy's Cellphone!, Rosalina was with Mario the whole day, leaving there no time for Mario to call a prostitute. She also attempted to call the police on Mario in The Dead Body!, assuming that Mario purposely killed a hobo, without any evidence that he purposely did so, or letting him give an explanation. Due to the fact she was attracted to Atso's body in " Shrek's Coma!" she is show to have pedophilia urges Rosalina is shown to be nice to Junior, he is shown to have a little crush on her (as Junior told Jeffy that his mother is very hot in Jeffy's Birthday!), but it's unknown if they still have a good relationship since “Jeffy and Junior Sneak to Disney World!”. However, in recent videos, Bowser Junior is shown to dislike her. in Jeffy and Junior sneak to Disney World, he insults her by calling her old. In Among Us, when Rosalina was the first one to report Jeffy. Junior is the first one to call her sus. Eventually in 2020, she eventually still gets frustrated with Mario when he becomes very greedy and selfish in recent videos. However, due to her own unintelligent nature, she tends to give very dumb advice on why Mario shouldn't be greedy, such as in Mario Sells Jeffy! when she thought that people only went to work "for fun" and not to pay for bills, food, and other necessities. Anthony Miller (zombie form in " The Zombie Apocalypse!" and voice loss in " Brooklyn Guy's Bad Day!") Rose (formerly known as Rosalina) is the wife of Marvin and the adoptive mother of Jeffy and She is one of the main characters of the series. Rosalina made her debut in the American Idol reboot, but she wasn't properly introduced until " Mario's New Girlfriend!". She is a human who was born and raised in outer space by two green aliens, and it's possible but yet to be confirmed that she still lives with them. On October 27, 2017, Rosalina married Marvin.
