Biography
This portrayal is a mixture of Harleen Quinzel from the canon initiated in Batman: The Animated Series, and later explored in the graphic novel Mad Love and The New Batman Adventures series as well as the short-lived live-action television series Birds of Prey (which was loosely based on the comic of the same name). She is a Nolanverse take on the character. She interacts with many non-Nolanverse characters across fandoms and multiverses, even alternate versions of herself.
Harleen’s timeline is set post-TDKR. Post-TDKR she doesn’t yet know that Bruce Wayne survived the explosion of the nuclear reactor and she mourns him deeply, Harley even more so. She and Commissioner Gordon remain engaged, but were separated for months due to the events of the terrorism enacted by Bane and are piecing their lives and Gotham back together. While she is a forensic psychologist for the Gotham Police Department, post-war she is working primarily as a medical doctor for police personnel and also dealing with civilian casualties when needed. She is also using her training as a psychiatrist to treat members of the GPD for Post Traumatic Stress Disorder. The shock and the stress of Gotham’s time held hostage by and at war with Bane’s liberation have had an effect on her, muting parts of her personality and exacerbating preexisting conditions.
The original playby for this character was actress Mia Sara, who portrayed Quinzel on the live-action show. The Harleen in this RP is an older, far more calculating and thoughtful person with a latent sinister streak. She is less bubbly than her comic and cartoon personas but still enjoys jokes and puns and is socially awkward when it comes to matters of love. This character started off as Harleen as she was prior to her taking the Joker on as a patient at Arkham (for reference, the Joker for this character is under the handle of Patient # S-4479). 
She has since treated the Joker; this is prior to her resigning. She is not Harley Quinn, she remains Harleen Quinzel; however, she has been diagnosed with Dissociative Identity Disorder and has presented with three personalities: Harleen, Harley, and a third who has not been identified by name but has been referred to as either Alichino or Arlecchino. The playby for this character is actress Marley Shelton.

Like her comic and cartoon counter-part, this Harleen Quinzel is trained in the field of psychoanalysis, is a talented gymnast with high human agility and strength, above average fighting skills, and proficiency in martial arts. She is also is a practitioner of capoeira and yoga and is experienced in tactical combat escrima, though she uses police-grade batons instead of yantok.
Liberties were taken with the character background by changing the name of her mother and father and in expanding on her father’s criminal history, as well as making Harleen a semi-observant member of the Jewish faith. She also has over ten years of experience in practicing psychiatry and four years experience in trauma medicine.
Her father’s name in this RP is Harold Raymond Quinzel, known as Harry or Happy Harry. He is a member of the Irish-American mob. His father, James Francis Quinzel, was a member of the Westies. Harleen’s grandfather was murdered in front of her by a rival gang. It was this event that led to the formation of her two alters. The play by for Harry Quinzel is the late John Spencer. 
Her mother’s name in the RP is Ruth Goldberg Quinzel. Her mother is semi-retired, sometimes working on her familiy’s jewelry business, which is run by her older brother Samuel. Her maternal grandfather, Benjamin, is still alive and lives in a retirement home. He was a jeweler and handed over the day-to-day of his business to his children. His wife, who had survived Auschwitz, passed away when Harleen was a child. The play by for Ruth Quinzel is Swoozie Kurtz. 
Harleen’s younger brother Barry (his canon name) lives at home with their mother. He’s a struggling musician and he and Harleen don’t get along in general since he dropped out of college and has very different ambitions than his sister. After seeing how things are for her in Gotham, Barry quietly finished his bachelor’s degree and began attending the NYPD Academy to become a police officer. His play by is Adam Goldberg.
Harleen was involved in a relationship with Steve Rogers, also known as Captain America, which ended when Steve was murdered by Norman Osborn. Steve proposed to Harleen as he was dying, giving Harleen his mother’s wedding ring. 
The murder occurred in retaliation against Tony Stark (Iron Man). Steve’s body was subsequently stolen from a non-publicly disclosed location and he was resurrected by unknown persons for still unknown reasons. He awoke and was discovered wandering a mountainous region by local authorities and was held in federal custody at his Red Hook, Brooklyn apartment. Interacting with Harleen’s younger brother led to the return of all of Steve’s memories, but he still does not know who brought him back to life or why.
As a result of that and the events which led up to Steve’s murder, Harleen moved into Bruce Wayne’s penthouse in Gotham. 
She and Bruce have known each other for sometime, first professionally, and then personally. She considers him to be one of her best friends and sees Alfred Pennyworth as a fatherly figure, Lucius Fox as well. She and Bruce were seriously dating one another and had been living together most of the time. They’ve since broken up and Harleen has her own townhouse in downtown Gotham now. The townhouse was a gift to her from Bruce when they parted, a way to continue to take care of her even though they’re now apart.
Harleen and Commissioner Gordon started off as friends and coworkers and are dating. They are starting to deepen their relationship. Jim recently divorced after a five-year separation from his wife. 
He and Harleen are in love with each other and are at the point in their relationship where Jim has proposed marriage. Their working situation brings complications to the relationship, even though Harleen doesn’t directly report to Jim. Their unusual work hours also mean they are apart for sometimes days at at a time. Harleen and Jim came to know one another over the course of her working with and now working at the Gotham Police Department. Harleen no longer works at the Elizabeth Arkham Asylum for the Criminally Insane (now known as the Elizabeth Arkham Psychiatric Hospital) as a result of the events leading to and culminating in Steve’s murder. She resigned prior to his death and has worked for the Gotham Police Department as a forensic psychologist for nearly a year now. She retained her licenses to practice medicine and psychology after petitioning both the state boards of New York and New Jersey.
Dr. Pamela Isley acts like a sibling toward her, albeit one that is prone to being flirtatious as well. Harleen is thoroughly confused by the older woman. Pamela is also a woman whose motives elude Harleen, but she seems to have taken a liking to her friend and former house guest Bruce Banner, so Harleen has a measure of trust toward her, though recent discoveries about her methods of protest for the environment have put her under watch by the GPD. 
Canonically, Gotham City Sirens #7 establishes that she was born and raised in Bensonhurst, Brooklyn into a Jewish-Catholic family. Her unnamed father is a con artist who is still in jail. Her brother, Barry, is a slob with dreams of rock stardom and is a neglectful father, and her mother, Sharon, wants her to stop the “villain and hero stuff”. In this RP, her father’s name is Harold Quinzel, a Catholic, his wife is Ruth Quinzel, who is Jewish. Her brother’s name remains Barry; however, he doesn’t have children. Additionally, her middle name is spelled as Francis as opposed to Frances. Harley Quinn #4 places her IQ at genius-level, contradicting earlier canon.
