Alison DiLaurentis (Sasha Pieterse) was the "it girl" of Rosewood and the leader of her clique. Ruling the group with an iron fist, the vicious but charismatic Ali went missing during a slumber party at the end of summer. When Aria, Hanna, Spencer, and Emily begin receiving threatening messages from "A" a year after Ali goes missing, they think she is alive and is playing a trick on them. However, shortly after the appearance of "A", Alison's body is found buried in the backyard of the former DiLaurentis house, hidden under the gazebo (which had been under construction at the time of her disappearance). The discovery of her body launches a murder investigation. The police believe Alison was killed by a blow to the head (with a shovel), but the girls later learn, via Alison's autopsy report, that she actually suffocated to death by being buried alive. In season 4, it's revealed that Alison is in fact alive, and has been on the run for 2 years because of 'A'. In the season 4 finale, she meets the girls and tells everything that happened the night she disappeared.

From episode 2 of season 6, Alison finds a new love interest in Toby's police partney Lorenzo .
Mona Vanderwaal (Janel Parrish) is a former unpopular girl at Rosewood who longed to be accepted into Alison's group and was continuously mocked by Alison. After Alison's disappearance, Mona completely transformed herself and befriended Hanna, and they both became popular students. She enjoys bullying Lucas, much to Hanna's annoyance. After the appearance of A, Mona notices that Hanna is now acting strangely, and feels jealous that Hanna has rekindled her friendships with Aria, Emily, and Spencer. She dislikes Caleb and makes attempts to break Hanna and Caleb up, even asking Lucas for help (though he declines). Mona is somewhat romantically involved with Noel, which Hanna disapproves of. Although Noel breaks up with her, Mona acknowledges that Hanna was right about Noel. Mona? knows the existence of "A" as she too is now a victim of "A". "A" threatens to put Mona in jail for stealing, unless she puts Hanna's police file public for all of Rosewood to see. Mona doesn't do so and instead returns the necklace she stole back to the jewelry store where she was confronted by the cops and was ordered to do community service by working in a soup kitchen. Despite this, Mona is still being threatened by "A". Hanna decides it's best if Mona hangs with her and the others for protection from "A". On the last episode of Season 2 it is revealed that Mona is "A" . . . or one of multiple "A's". She ends up having a mental breakdown and threatens Spencer by giving her the option of either "joining the A Team" or "disappearing" via Spencer's father's gun (Mona admits that she was the one to steal it from his desk). Mona shifts into an even more enraged frenzied state when Hanna, Aria and Emily show up (Spencer alerted them via her cell phone) and attacks Spencer which results in Mona falling off of the nearby cliff. Mona survives, but is committed to a mental hospital and by her doctor, is diagnosed with an antisocial personality disorder, borderline personality disorder coupled with her high intelligence (she was living in a state of "hyper reality" where everything revolved around her). . . which explains how she was able to be aware of everything going on all of the time while acting ditzy and superficial (she also was recording all of Hanna's cell phone conversations and had easy access to the girls' personal dwellings). At the end of the episode, Mona is visited by a mysterious stranger (dressed in a red coat) in the mental facility and admits she did everything that she was "told to do". This implies that Mona is just one of many "A's" and there is someone else calling the shots. In Season 4, she is targeted by the current leader of the A-Team (Red Coat) and is now a quasi-liar. In the mid-season finale of season 5, she is brutally murdered by someone who resembles Alison, and is stated dead by the police. However, in the season 5 finale, she is revealed to be alive, and has been helt captive by 'A' for five months. She is rescued with the girls, and her mom takes her away for healing. She returns to Rosewood again in episode 5 of season 6, and kind of begins to help the girls find out about Charles. It is revealed that Mona met Lesli at Radley, and that Lesli heard about Charles and shared a room with Bethany Young.
"A"'s identity is Mona, which was revealed at the end of Season 2. But the directors clue in that maybe she wasn't the only one sending texts and tormenting the four girls. At a party Hannah remembers who " A" is. Spencer goes with Mona to try to find Officer Wilden. When Mona starts going on a detour. Spencer asks where they are headed and Mona starts to tell Spencer all about how she was A and how she managed to keep it up. Spencer is freaked out and calls Wilden, and loudly talks to him about their where-abouts so he can find them. Mona then realizes what was happening and attacks Spencer at Dead Man Quarry. Mona and Spencer fight and Spencer pushes Mona off the cliff into bushes. The police arrive soon and so do the girls. Mona is then put into a mental hospital. But the girls are not done with "A" yet. It then flashes to a person in Alison's red jacket walking up to Mona in the mental hospital. Mona says to this person, thought to be "A," that she did everything that they asked. This implies that Mona, like many others, was just working for "A."In the season 3 summer finale you can see a person in a black hoodie turning around and that person is Toby. It is implied Toby is a part of the A team. In the season 3 finale, it's revealed that Toby only joined to protect Spencer and to find out who Red Coat was. Toby, along with Mona and Spencer, are kicked off the A-team after the incident at Thornhill Lodge . In season 4, a new person named (unofficially) The Black Widow appears with the Alison mask on. However, she doesn't make an appearance in a long time. In the season 4 finale, a black hooded person shows up and tries to kill the Liars with a gun. Ezra also shows up on that rooftop, and reveals that he knows who the person is. Ezra and that person fights, and after that person escaped, the camera turns to Ezra, who is shot in the stomach. In the season 5 premiere, Aria stays with him at the hospital, and when he's concious he tells Aria who 'A' is. Aria rushes over to where the rest of the girls are, and finds them along with Shana, who is revealed to be 'A'. Shana, almost killing the girls, is killed by Aria in self defense.
In season 5 episode 6, 'A' returns and it's revealed that Shana was never 'A' since (quote Aria) "she never used those words".

However, later on in the season, Lesli is shown to be two-faced as she testifies against the Liars and Alison in court. She is completely different as compared to her earlier demeanor where she seems friendly.

She also wastes no time in vilifying Alison in court and produces a card that Mona allegedly sent her containing evidence of how Alison had threatened her. In Season 6, after Mona's return to Rosewood, Lesli is again shown to be totally different from the Liars' intial perception of her as a loyal friend to Mona.
