Uber A is the main antagonist of Seasons 6B and 7 of the television series "Pretty Little Liars". They are an anonymous Big Bad who wishes to uncover the truth behind the murder of Charlotte DiLaurentis and he/she believes the Liars know the truth.
Unlike Mona and Charlotte, Uber A does not wear a black hoodie but instead wears various masks and disguises.
Uber A begins texting the Liars after Charlotte's death, using emojis instead of "A". Uber A threatens them to hand over Charlotte's murderer.
Eventually, after Uber A gives them a deadline, Hanna and Caleb hatch a plan to "deliver" the killer to Uber A, whom Caleb nicknames "A-moji", by having Hanna lie and say it's her. The plan works and Uber A is supposed to meet Hanna in the Lost Woods Resort, where Caleb, Ezra and Aria are waiting outside to trap him/her. However, Uber A has other plans. Mary Drake sets off the alarm, while Uber A grabs Hanna through a whole in the floor and takes her to the Bell Tower. Uber A then texts the others and thanks them for giving him Hanna, signing the text as "A.D."
The Liars found a doll in a church that told them that they had 24 hours to give him Charlotte's real killer or Hanna will die. They came to the decision that Alison murdered Charlotte and they left a red sweater (that they think Alison wore while murdering Charlotte) for Uber A to take as proof. Upon finding the evidence, Uber A picks the sweater up and puts it in a bag. Eventually, Uber A realized that Alison wasn't Charlotte's killer, and she was rescued by the Liars, who accidently killed one of his helpers, Archer Dunhill, in the process.
In order to obtain proof, he disguised him as Archer and attacked Alison, causing Spencer and Hanna to check if he was dead by digging up his grave, which Uber A recorded. Later, Jenna Marshall and Noel Kahn, two other helpers of Uber A, attempted to kill the Liars. Noel was killed, also accidently, but Jenna was abducted and dragged by Uber A after her failure. He loads her in a van before driving away.
Uber A is assisted in his/her game by helpers. Uber A's current known helpers are:
- Mary Drake: Revealed in the sixth season finale, Mary was hired to help drive Alison insane. In order to do this, Mary pretended to be her sister Jessica and visit Alison in a comforting way. However, she then dressed up as a dead Jessica to scare Alison.
- Archer Dunhill: Revealed in the sixth season finale, Archer is currently the suspect of being Uber A himself. However, as of now he has only been confirmed to be involved in the scheme, dressing up as the deceased Darren Wilden to drive Alison insane. He was accidentally ran down and killed by the Liars with their car while he was trying to take Alison somewhere.
- Jenna Marshall: Revealed in the seventh season, Jenna was revealed to have known about Charlotte and was friends with her at Welby. She is angry at her death. She was also being paid by Archer to assist them until his death.
- Uber A will be the final "A".
- The main suspects of the fandom are Melissa Hastings, Wren Kingston, and Lucas Gottesman.
