- Mona to Charlotte in "Farewell, My Lovely"

Mona Vanderwaal is a main character in the television series Pretty Little Liars and Pretty Little Liars: The Perfectionists on Freeform. She is portrayed by Janel Parrish.

Mona was revealed to be the first and original "A" in "UnmAsked" and was sent to Radley Sanitarium for psychological and emotional treatment for a few months. In "Taking This One to the Grave", she faked her death with the help of the "A|A" that had taken over her game. However in "Welcome to the Dollhouse", it was revealed that she was alive, having been double-crossed and being held captive in A's dollhouse. She was later revealed to be the killer of Charlotte DiLaurentis, the second A.

Biography
In "Burn This," Mona reveals that Hanna and she were friends in 8th grade. Eventually, however, Hanna becomes a part of Ali's clique and Mona was subjected to her bullying.

Deep down inside, Mona never forgot the way Alison had previously treated her; as an outsider and a dork. She was nicknamed 'Loser Mona' by Alison. Ironically, Mona begins behaving like Alison after she assumes Alison's place as a Queen Bee. She taunts Lucas as Alison used to and calls him Hermie, despite once being his friend when Alison bullied them both.

Mona is a very self-conscious person. Due to the bullying and rejection she faced when Alison was around, Mona developed a complex in which she is not happy with her life. Although she does not show this side of her in public, this is why Mona felt such a need to remain popular, beautiful, and best friends with Hanna. This is also why she started tormenting the girls as "A," because she was afraid that the Liars would steal Hanna from her again, who was her only friend. She and Hanna became best friends again when Alison's crowd was disbanded. Mona figured that Hanna would not give up the chance to become popular. Their friendship stays strong until the ever so infamous "A" begins torturing the girls, forcing Hanna to become closer to her old friends. The other Liars don't care much for Mona, and this is a source of conflict in certain episodes, but it ends up being much more severe then a simple annoyance when it is revealed that this is the very reason she became A; she was angry at the Liars for taking Hanna away from her.

Mona can also speak French, hack computers, and do voice impressions. Mona was revealed to be "A" in the Season 2 finale. She considers herself a genius but also has a personality disorder (according to Dr. Anne Sullivan). Mona was under the influence of someone in a red coat until she is kicked off the A-Team in the season 3 finale.

In Season 5, after it was revealed Alison is in fact alive, Mona forms as "army" of people who were victimized by Alison prior to her disappearance, to fight against her return. The group included Lucas, Paige McCullers, and Melissa Hastings. In the Season 5 summer finale, Mona was believed to be brutally murdered in her own home after discovering what she believes to be proof that Alison is 'A'. The police believe she was murdered, due to the amount of blood spread over her home, they say that her wounds must have been 'fatal'. Her assailant is unknown. Her relationship with Mike Montgomery was on and off. In "Welcome to the Dollhouse," it is revealed that Mona is alive and being held captive by "A", she is forced to pretend to be Alison and her hair has been dyed blonde.

Pretty Little Liars
Pilot In one of Aria Montgomery's flashbacks, Mona is shown with glasses and 2 pigtails, trying to hang out with Alison and Aria. She asks them to wait up, but Alison DiLaurentis tells Aria to ignore her and Aria obeys, running away from Loser Mona. Mona is crushed and wraps her arms around herself. After Alison's death, Mona is first seen with Hanna Marin shopping in the mall. They comment on each other's accessories that they stole before Hanna goes to talk to Spencer Hastings. Mona shoplifts a scarf then meets up with Hanna who shoplifted a pair of $350 sunglasses.

Ashley thinks the police report was sent to Hanna, not Mona, and gave it to Wilden because she think it will keep them safe. Mona has an idea.

Mona speaks for the first time since Hanna's visits - "You're getting them again, aren't you? The texts?" Before Hanna can get anything out of Mona, she's shuffled out of the room. Alone in her seat, Mona slides tweezers out from under her and pricks her finger with it, allowing a drop of blood to bloom.

"Where were we? Maya's away sleeping sweet until Garrett's all rosy count on me." - www.massugar.com

"No one to save Ali from evil." - Not safe.

Mona is then sent back to her room. Later, Hanna tells Aria, Spencer and Emily that Mona was using a code that they had once used to write mean stuff about Alison on her missing flyers. Using the first letter of each word, they realize that the second code/riddle (see above) translates into "www.massugar.com" - Maya's website.

Hanna realizes that this person is a fake, and tears off their mask, revealing another mask and a blonde wig, made to look like Alison.

When Mona started receiving texts from A, Emily grew closer to Mona but they still weren't considering one another friends. After Mona was revealed to be the infamous A torturing them, Emily didn't trust Mona and never fully had. Years later, Mona helped Emily (and the other Liars) find out information about Charlotte and Archer, who Alison's sperm donor was and the doctor who performed the procedure, and helped her (along with the other Liars) beat Liars Lament. The two are now friendly with one another, although Emily doesn't completely trust Mona and probably never will, with Mona wanting to earn Emily (and everyone else's) trust.

Family
Leona Vanderwaal: - Mother/Daughter Leona and Mona have an interesting relationship, as Leona has only interacted with Mona on a few occasions. Following Alison's return Leona was afraid that Alison's tormenting and bullying had begun again with her daughter, and confronted Hanna about it. Later, over the Christmas holiday, they planned to leave town to visit their family but Mona had to stay behind to handle some things but promised to meet her mother there. When Mona was believed to be dead she went after Alison as she believed that Ali had killed Mona and knew where her daughters body was. When Mona returned to Rosewood from the Dollhouse, Leona picked her daughter up from the hospital and the pair went on a spa trip together. They also visited Saratoga together.

Other Friends
Lucas Gottesman: - Friends and former allies Lucas and Mona bonded over their mutual hatred for Alison, and their fear of Ali returning to her wicked ways when she came back to Rosewood High after having been missing for over a year. Lucas was also a member of "Mona's Army", and helped her in her attempt to stop Alison from rising to popularity again so she couldn't bully anyone else. Additionally, Lucas was rather nice to Mona when they were both at the bottom of the social rankings in High School, which made Mona feel better on days when Alison would torment her.

Lesli Stone: - Former friends Lesli and Mona met when the duo were both patients at Radley Sanitarium. No one really knew about the pairs friendship except for Mona's mother, Leona. Lesli first appeared after Mona's faked death and seemed genuinely upset about the fact her friend was dead. She also helped Mona put Alison in prison, by falsifying and exaggerating evidence for her. However, when Mona returned, Lesli lashed out at Mona and blamed her for the fact that she was now an accessory to Mona's crime (faking her death). In an attempt to make it up to Lesli, Mona tried to steal Lesli's Radley file so that the Liars wouldn't find out that she was in Radley and knew of Charles. Mona failed and this lead Lesli to lash out at Mona and the two consequently stopped being friends.
