A classic overachiever, Spencer is confident, calculating, and could stand up to Alison when no one else could, showing her determination.

- Heroic B.S.O.D.: As of "Out of Sight, Out of Mind".
- Gender-Blender Name: Spencer is traditionally a male name, although it's not unheard of in females in real life. In television, however, it's not that common.
- The Glorious War of Sisterly Rivalry: She doesn't really understand why, although being The Unfavorite has a lot to do with it. That and her sister's abominable taste in men, who constantly go after Spencer.

Emily: [Pregnant paus] ... I think I know what I want. ... But if I say yes to Maya, everything would change. You know it would.
Hanna: Yeah, it would. You wouldn’t have to pretend you’re someone you’re not.
Emily: But what if I’m wrong? What if I’m not … that person?

Aria: No, you just happen to be the sporty one.
- Lipstick Lesbian: She's shown to be feminine and fashionable (maybe a Tomboy with a Girly Streak since she is also an athete).

In the second season, it looks like Emily may move to Texas with her parents for a year, but she convinces them to let her stay with Hanna instead.

- Nice Girl: She is the sweet and loyal "good girl" of the group.

Voiced by: Valentina Souza (Latin-American Spanish dub), Yoko Honna (Japanese dub)
- "Friends share secrets. That's what keeps us close."
Alison was the "It Girl" and the Queen Bee of Rosewood High School until she mysteriously disappeared.

- The Ace: The reason why she was the "It Girl", since she is attractive, smart and charismatic.
- Adaptational Heroism: She's still an Alpha Bitch, but she's nowhere near as horrible a person as she was in the books. She's not the Big Bad and, after her return to Rosewood, seems to be trying to shed most of her Alpha Bitch traits.

- The Atoner: The time she spent on the run has apparently made her realize just how much damage she did as Alpha Bitch. In "Whirly Girl", she even tries to make amends to Mona and says that the awful person she used to be is gone. Her words during her fight with Mona in "Miss Me x 100" cast some doubt on whether or not she is genuinely trying to change her ways, though:Alison: All I had to do was say "I'm sorry" and Mindy and Cindy were begging to be my friends again.
- Big Damn Heroes:
- She runs into a fire to save Aria, Hanna, Emily, and Mona.

- Faking the Dead: She survived a blow to the head and being buried alive, but disappeared afterwards to make her attacker think she had died.
- The Friend Nobody Likes: A dark deconstruction with Alison. While everyone in town hates her, the Liars put up with her. However, they spent most of season five wondering why and turned on her when she continued to lie to cover her tracks. They even suspected her of murder and did everything they could to get her arrested.
- Heel Realization: Being in prison makes her realize how horrible she was to her friends. By time they realize she's being framed and reach out to help make things right, she feels she's the one who owes them an apology.

- Or Was It a Dream?: Every time she appears in the present, there are ambiguous circumstances that make the viewer think that she could still be alive.
- Posthumous Character: Or not, since she actually comes back and is revealed to be still alive.
- Properly Paranoid: Being almost murdered will do that to you. She has a short list of people that she trusts.
- Secret Identity: As Vivian Darkbloom.
- Secret Relationship: With both Ian and Ezra during the summer before her disappearance.

Portrayed by: Janel Parrish
Voiced by: Cecilia Gómez (Latin-American Spanish dub), Eri Goda (Japanese dub)
- "It's easier to forgive an enemy, than it is to forgive a friend."
A former loser who was tormented by Alison (yet still idolized her), Mona and Hanna became really close friends after Ali goes missing, and become the top popular girls of Rosewood High. She's witty and can be mean at times, but treats Hanna like a sister and seems to get along with the other Liars as well. The second season finale reveals that she's A, and she's sent to an asylum after being diagnosed as insane. She returns to school after "getting better" in the second half of season 3, but continues working with the second A all along, until she's betrayed in the season finale and almost burnt alive with the Liars. She is promoted to main character status in the fourth season.
- Adaptation Dye-Job: Blonde in the book, brunette in the TV show.
- Adaptation Expansion: In the original book series, Mona dies when she tries to kill Spencer. While the same scene happens in the Season 2 finale, she manages to survive. Everything from that moment onwards has been created exclusively for the TV series.
- Adorkable: Before Alison's disappearance.
- Alpha Bitch: In early Season 1.
- Ambiguously Bi: She is EXTREMELY fond of Hanna. "A Is For Answers" hints that she was attracted to Ali as well.
- Ambiguously Evil: In Season 4, after her supposed Heel–Face Turn. It's still unclear if she has genuinely ended her vendetta against the Liars.
- Ascended Extra: Her role wasn't that influential in the first season, but she gradually starts gaining more importance as from the second season onwards. In season 4, she becomes a main character.
- Big Bad: For the first two seasons, though none of us know this until the end of the latter. In Season 3, she becomes The Dragon, while pretending to have reformed, until she's expelled from the A Team in the finale. She becomes an anti-hero in Season 4, but returns to Big Bad status in Season 5A, after she bands together an army of Ali haters to work against her. Ali ultimately takes the role from her near the end, when she goes rogue and starts her own army.
- Big Bad Duumvirate: With Charles in Season 3A. It seems that at the start Mona and Charles/Big A were working together as partners, but Big A eventually took the game away from her and made it entirely his.
- Big "NO!": Upon discovering the RV was gone.
- Bitch in Sheep's Clothing: Zig-Zagged in regards to Hanna: On the one hand, she used her friendship with Hanna to gain inside info on the girls, making her more effective as A. On the other hand, she seems to truly care about what happens to Hanna.
- Brainy Brunette: One of the few characters who can match Spencer intellectually. She usually tries to downplay it.
- Broken Ace: Her unique repertoire of skills that allowed her to flourish as A makes her a useful ally to the Liars in later seasons, but the group (sans Hannah) never truly trusts or accepts her. She's also a mentally unbalanced individual who tends to lapse back into unhealthy behaviour and obsession.
- Darker and Edgier: As the series progresses, her character becomes much darker than the light-headed girl in the beginning.
- Dark Horse Victory: And how. She's the ultimate winner of the A game in Season 7, outwitting the Big Bad, and imprisons her (and her mother) in her personal dollhouse in the penultimate scene of the series.
- Deadpan Snarker: Now that she's been revealed as A, she indulges in this on occasion.Spencer: "If you so much as touch one hair on their heads, I will make you very sorry!"Mona: (smirking) "Looks like someone's been skipping her anger management classes."
- Deal with the Devil: Invoked. She describes her arrangement with the true A as this. Basically, she became The Dragon and gave control of the A-team over to the true A and in exchange, the true A arranged free passage in and out of Radley for her. Now, whether or not she was telling the truth about that is open to interpretation.
- The Dragon: To the second "A". She also sort of becomes this to Ezra Fitz in Season 4, but clearly does not want to be in his employ.
- Evil All Along: Is revealed to be the first "A".
- Evil Former Friend: Mona was Hanna's best friend and later turned into her worst nemesis.
- False Friend: Mona is Hanna's best friend but only uses this to gather information on how to take the girls down as "A".
- The Fashionista: Along with Hanna, she is stylish and interested in fashion.
- The Friend Nobody Likes: To the Liars. Even before she was revealed as A, only Hanna liked hanging out with her. After she is revealed to be A, she's generally kept around because she's useful and Hanna still likes her a little.
- Girlish Pigtails: In flashbacks, the pigtails were part of her dorky appearance.
- Good Girl Gone Bad: She used to be a nerdy harmless girl who was frequently bullied by Alison in the past. She changes after she becomes popular.
- Heel–Face Turn:
- She's trying to convince Rosewood that she's made one, but "Mona-Mania" confirms that she is definitely still on A's side.
- She makes one for real in "A dangerous gAme".
- Heterosexual Life-Partners: With Hanna, after Ali vanishes from the picture. They later grow apart, as Mona was revealed to be in the A Team, but their distance is bridged a little in the season 4 premiere. It will probably never be what it was, though.
- Hollywood Nerd: Before Alison went missing.
- If It's You, It's Okay: Mona is completely heterosexual by her own admission, but she jokingly tells Hanna that she's totally go gay for her.
- It Meant Something to Me: Despite having used her position as Hanna's best friend to help her attack the girls as "A", she tells Hanna this in the Season 4 premiere:Mona: I really did love you... (Beat) and I really was your friend.

- Open-Minded Parent: Becomes a lot more open-minded in the third season.
- Parental Favoritism: Same case as her husband.
- Put on a Bus: She goes to London with her husband in the third season, but makes an impresively quick return when Spencer is sent to Radley.

He's a shy, quiet boy who was framed by Ali for the prank that made Jenna Marshall lose her sight, and spent some time in juvie because of that. He quickly becomes the lead suspect in Alison's murder investigation, and is regarded as an evildoer by almost all Rosewood. He begins a romantic relationship with Spencer by the end of season 1.
- Adaptation Expansion: He has a bigger role in the tv series, where he remains very much alive, unlike the book series.
- All Girls Want Bad Boys: According to the people of Rosewood, at least, this fits her relationship with Spencer. And then we learn that he's in The A Team, which gives a whole new meaning to this.

Toby Cavanaugh's blind step-sister. She's a sly, smart young woman who had a very complicated rivalry with Alison after she turns down Ali's offer to join her group briefly after moving into town. The Liars accidentally caused her blindness in a prank intended for Toby that went horribly wrong. She does not approve of Toby's relationship with Spencer, but eventually Toby pushes her aside to be with Spencer.
- Ambiguous Allegiance: It's pretty tough to tell what side of this whole mess Jenna lands on. Some fans have theorized that she's working with A, while others have suggested that she's actually A's enemy and will later work as an ally to the main characters. Really, it's anyone's guess.

- Deadly Prank: Became blind when she was the accidental victim of one by the protagonists.
- Deadpan Snarker: Has some traces of this.

She was up against Emily for the Anchor Leg and tried to sabotage Emily via intimidation. However, soon after, Paige comes out as a lesbian to Emily, her long time crush.
- Action Girl: She can definitely hold her own in a fight. She was able to save Spencer from the person in the Queen of Hearts costume by beating said person up.

- Driven to Suicide: Narrowly averted in the backstory. Alison was apparently so cruel to her, that she considered this. The only reason she didn't is because she realized doing that would mean "Alison would win.".
- Duet Bonding: She and Emily became closer after singing a duet of P!nk's "So What?"
- Girliness Upgrade: She's initially less feminine than Maya or Samara, and is far more aggressive and competitive (including almost drowning Emily), and yet she's not quite the Butch Lesbian due to the makeover she gets in season 3: the writers decided to make her Hotter and Sexier and so she was presented again with longer hair, sexier clothes and more Lipstick Lesbian tendencies.
- Heel–Face Turn: After we find out that she's gay.
- Hotter and Sexier: As the series progresses, Paige gets a makeover, long hair and sexier outfits.
- Informed Ability: According to Spencer, she's a great field hockey player (a penalty was named after her!) but like with Spencer, we never get to see her play.

- Lesbian Jock: As a swimmer and a hockey player. There's even a penalty named after her.
- Locked Out of the Loop: By season 3, she and Ezra are the only ones of the main characters' love interests to not know about the second A.

- He Knows Too Much: The reason why he's murdered by Darren Wilden in season 3.

- In "The Lady Killer", it is confirmed that he didn't kill Maya.
- Also, in "This Is A Dark Ride", he tells Spencer he didn't kill Alison, but Jenna genuinely believes he did.

- Otaku: In a flashback in Season 2, Jason gets angry at Alison. When Aria asks what was up, Alison says that he thought she had stolen "one of his Japanese cartoon porn books", implying he is (or was) a Hentai fan.

- Off the Wagon: Drove drunk in "crAzy".

Voiced by: Mildred Barrera (Latin-American Spanish dub)"Take it from me, you're always better off with a really good lie."
- Alpha Bitch: Has some traces of it.

- Big Sister Worship: The subject of such from Alison, despite not being sisters. Turns out that they actually are.
- Blatant Lies: she told Emily that she didn't know the "beach hottie" in Cape May is.
- Canon Foreigner: CeCe does not appear in any of the books. Though, she is somewhat based on the real Alison from the books.
- Composite Character: She combines the backstory of Courtney from the books ( long-lost DiLaurentis sister who spent most of her youth stashed away in Radley) with the personality and role in the plot of Book!Alison ( murderous sociopath who torments the Liars as the second A).
- The Corrupter: According to Jason she was a seriously bad influence on Alison.
- Daddy Issues: Much of her sociopathy is because her father refused to accept that she is transgender and forced her to grow up away from her family.
- Deconstructed Character Archetype: Of the Hidden Villain. As A, she is initially presented as a dangerous Manipulative Bastard who can predict the Liars' every move and come up with the perfect counter-move. However, once her identity is revealed and all the intrigue stripped away, she comes off less as "cool" (like the typical Hidden Villain) and more as tragic and pitiful. In the end, even her former victims can't help but pity her.
- Driven to Suicide: She plans to kill herself in "Game Over, Charles", but is talked out of it by Alison and her friends.
- The Fashionista: And makes a living out of it too.

Elliot Rollins/ Archer Dunhill
"I'm still here bitches, and I know everything."
- Big Bad: Both "A's" are the Big Bad of their respective seasons.
- Big Bad Duumvirate: Mona and CeCe shared the identity of "A" in Season 3A, before she fell into The Dragon. This is back into play now that we know Red Coat is Charles' accomplice.
- Catch-Phrase: Tends to end her messages with "Bitch" or "bitches", though not quite to the point of being a Verbal Tic.
- The Chessmaster: Manipulating, blackmailing, and threatening the girls with text messages.
- Dark Is Evil: "A" makes appearances as a figure with black leather gloves, a black hood, dark pants, and dark shoes.
- Hidden Villain: A is the main antagonist of the show as they constantly blackmail the girls and has even attempted to kill them on several occasions. Their identity still is a mystery.
- In the Hood: The infamous "A" costume is a black hoodie.
- Manipulative Bastard: Whoever takes this role (male or female) is clearly a skilled manipulator. Just ask the Liars.
- The Man Behind the Man: To their followers.
- The Omniscient: A has, on multiple occasions, demonstrated not only uncanny knowledge of people and their secrets, but actual prediction of future events. (Example: Emily picks a box of Alpha-Bits from the school cafeteria cereal selection, only to find that all of the pieces have been replaced with A's. Since we see no evidence that anyone else experienced this, that means that A not only knew that Emily would choose that brand of cereal, she knew exactly which box of it Emily would end up with.)
- One-Letter Name: Just goes by A.
- The Reveal: In "UnmAsked", "A" is revealed to be Mona Vanderwaal. She is sent to Radley Sanitarium for treatment, where CeCe Drake began visiting her and took away the game.
- This is for Emphasis, Bitch!: At times you wonder if A is really Jesse Pinkman.

- Big Bad Duumvirate: Turns out she was actually this with CeCe, the seventh "A".
- Bitch in Sheep's Clothing: Big time.

She's actually Red Coat and the Black Widow, who is CeCe's Dragon and accomplice and Emily makes sure she pays for it.
- Canon Foreigner: She doesn't appear in any of the books.
- Cool Mask: Wears an Alison mask to hide her identity from even the A-Team. Though, "'A' Is for A-l-i-v-e" suggests that she just hangs around in it, even when its burned on one half.
- The Dragon: To CeCe. She's her second in command and top ally in the "A" games. She was also somewhat in a Big Bad Duumvirate.
- Decoy Antagonist: More like Decoy Big Bad, since she's definitely an antagonist. She's somewhat part of a Big Bad Duumvirate with CeCe, the real Big Bad, and is her Dragon. However, the two of them had Mona and the A-Team believing it was Sara in charge.
- Hidden Villain: Both her real identity and her disguises. The Liars assumed Red Coat was gone, just thought Black Widow was suspicious and never suspected Sara.
