Detective "Rosa Diaz" (name is possibly assumed) is considered "the tough guy" and the "badass" in the precinct. Rosa is scary, smart, secretive, and difficult to read. Most of the members of the precinct are frightened and a little disturbed by her. Rosa takes pride in the fact that no one knows much about her (although actually Gina knows quite a lot)- in total, Jake only knows three facts about her, one of which is that she has a shower.
Rosa Diaz is a smart, tough and mysterious detective. Rosa previously attended parochial school where she was a model student and had a favorite teacher, Sister Bernadette. She also studied ballet at the American Ballet Academy but was kicked out for "beating up the ballerinas". She mentions in The Mattress that her ballet teacher, Ms. Miriam, used to complain to her about her "Posture, technique, and pink hair." The pink hair may be a reference to Stephanie Beatriz's hair, which sometimes has pink highlights in it. Rosa was eventually a classmate of Jake Peralta who was in the police academy, where the two became friends.
She is a recipient of the US Flag Bar, N.Y.P.D. Exceptional Merit, and N.Y.P.D. Firearms Proficiency Bar. In season two, Diaz believed she was pregnant with Marcus' child, until it is revealed she was not. She and Marcus breakup in Into the Woods and reveals that her current boyfriend is called Tom in The Swedes. It is presumed that she and Tom broke up some time between The Swedes and Cheddar, where she gets together with Adrian Pimento.
Her family come from Bensonhurst and her father is a teacher. She has two sisters and a niece, Diana.
She has curly, dark hair and often wears leather jacket or 'badass' clothes. She has dark, revengeful eyes and also has a thin cut in her right eyebrow from when Beatriz tripped on a Lego brick when she was 10. She often has an offensive stance, with her arms crossed and a scowl on her face.
Throughout the SeriesEdit
Rosa Diaz is a smart, tough and mysterious detective (it is revealed that her name might not even be Rosa Diaz, as she assumes multiple identities for different people). Although Diaz is a loyal and effective member of the squad, her anger management issues and lack of empathy terrify most of her coworkers. She is highly secretive about her personal life, and refuses to let any of her coworkers visit her home, despite living very close to the precinct. She is shown to own many weapons and believed that every woman should own an axe.
Jake and Rosa are good friends from the Police Academy and are shown to trust each other immensely. In Pontiac Bandit, it is revealed that Jake and Rosa have a pact called '1000 pushups' which means they have to trust each other. Jake breaks this trust but later makes it up to Rosa by actually doing 1000 pushups. In The Swedes, Rosa said that Jake was her closest friend in the world as they don't talk about personal issues. By the end of the episode, the two have developed a closer relationship as Rosa is more comfortable talking about personal issues.
Rosa and Amy have a friendly relationship and seem to be on good terms. In House Mouses Amy helped Rosa get over her fear of donating blood which shows that the two have a friendly and supportive relationship. However the two have shown rivalry such as in the bomb diffusing class and when Rosa gets offered to be the captain in Ropesburg.
Rosa and Gina have a strange, on and off friendship. Whilst they do get along in some episodes, Rosa has also been shown to mock Gina in several episodes, such as when Gina is afraid that she will die of Anthrax. ("I was insulting him. You know, flirting.")
Rosa and Charles previously had an uncomfortable relationship as Charles was in love with Rosa but it is not reciprocated. After Charles and Vivian start dating, Charles and Rosa become friends and Charles no longer has feelings for Rosa. They are shown to be friendly such as in Johnny and Dora, Charles plans a birthday party for Rosa that she likes and she lets him call her 'Roro'.
Rosa and Holt have a close, impersonal friendship. Both are uncomfortable with personal situations and avoid discussing personal matters. Things become complicated when Rosa begins dating Marcus, Holt's nephew but they manage to avoid discussing personal matters and even manage to help each other which brings them closer.
Rosa and Terry have a friendly relationship. They are shown to be working together such as when catching Hitchcock and Scully who are stealing their snacks. Terry is also shown to be helpful to Rosa by teaching her how to be good in court and kinder.
Rosa and Adrian have a romantic relationship that makes most people, especially Terry at first, feel uncomfortable. In Cheddar, the two are shown to be aggressively flirting and making the entire precinct uncomfortable. The two get engaged but their relationship is halted when Adrian has to fake his own death and leaves. Rosa is shown to be very upset by this but confident in his return.
Rosa and Marcus previously had a romantic relationship despite having very different personalities to one another. Rosa felt uncomfortable due to the fact that Marcus is Holt's nephew and doesn't want to complicate her relationship with her boss

It is also revealed that she rented the apartment from a shell corporation, her mail goes to a PO. Box in Queens and her real name may not be Rosa Diaz.

- She talks in her sleep.
Boyle: So where's your happy place?
Diaz: I'm in a cabin, in the middle of nowhere. Inside it's just me and that stupid, slimy defense attorney, and I'm beating the hell out of him. I break a dining room table over his head. Then I rip off his arm, and I shove it where the sun don't shine. Then I reach down his throat and shake his hand.
