Uber A

"I don't lurk in the shadows, I hide in plain sight."

- Uber A

Uber A  is the main antagonist in Season 6B and Season 7, who torments The Liars into divulging the identity of Charlotte DiLaurentis' Killer.

Whereas Mona and Charlotte could never be seen hiding in the shadows, this copycat 'A' hides in plain sight, via masks and disguises.

At the beginning of their game, this 'A' person does not sign their messages with the letter "A". Instead, they use emojis, which differentiates them from The A-Team.

After Hanna claims to be Charlotte's killer, they drop the emojis and start signing their messages with the initials "A.D."

Uber A watches the Liars before stepping into a black car at Charlotte DiLaurentis' funeral.

Charlotte's Web

Uber A places flowers on a fresh grave next to Jessica DiLaurentis' and walks over to a black car. Before stepping inside, their chauffeur tells them that he's sorry for their loss.

The Gloves Are On

Uber A cuts open a bin containing A's signature black hoodie and dumps them into a garbage pail, but not before going on the internet and searching "UNIFORMS".

New Guys, New Lies

Before driving away in a black car, Uber A takes a couple of pictures of Spencer sitting outside The Brew.

A figure, as a mailman, watches Emily sitting inside the Montgomery house from the window.

At The Radley, as a bellhop, the figure walks behind the girls and out of the hotel; they step into a black car and remove their disguise.

Do Not Disturb

Uber A makes Hanna give the backup drive from The Radley to them.

Instead, when they plug it into their laptop, Caleb appears on the screen with a message before a virus is planted in the computer that corrupts their files.

Where Somebody Waits For Me

Uber A cleans up an electric switchboard in The Radley secret basement for unknown purposes while listening to “Whistle While You Work” from Snow White.

We've All Got Baggage

While Hanna, Emily, and Alison enter Sara's hotel room closet, the figure, as a maid, walks into another room. As the girls escape, they walk back into the room after having heard it, and remove their disguise.

Still wearing the maid gloves, Uber A reads a manual to a universal remote control. Next to them, is a slice of white wedding cake meaning that they were likely at Byron and Ella's wedding.

Did You Miss Me?

Uber A receives a text from Hanna "confessing" to killing Charlotte.

Hush, Hush, Sweet Liars

Uber A allows Hanna one more day of life before confronting her.

At the Lost Woods Resort, the figure sneaks in through a hole in the floor and takes Hanna.

Later at The Church, they drag what appears to be her body, with blood on her face, to the bell tower with a bouquet in her hands.

Tick-Tock, Bitches
 * -|Season 7=

When the Liars get to the Bell Tower, they see that "Hanna" is strangled from there. When they pull her up, they see that it is a mask hiding a doll. Emily notices a string and pulls it and the doll is saying that they have twenty-four hours to find the real killer or Hanna dies.

A.D. has Hanna locked in an unknown location where they strip her of most of her clothes (which they used for the doll). They then proceed to torture Hanna by spraying her with a hose and then shocking her with a tazer. They use night vision goggles to see in the dark and hide their identity.

Caleb delivers a red sweater near the Lost Woods Resort as proof that Alison is Charlotte's killer. Upon finding it, A.D. picks it up and bags it.

Wanted: Dead or Alive

A.D. attacks Alison at her home wearing a cop costume. A.D. overpowered Alison but had to flee due to police sirens. Thinking that it was Archer who attacked Alison, Hanna and Spencer dig up Archer's grave to make sure he is dead. During this, A.D. records their digging and stores it on a laptop.

Original G'A'ngsters

A hooded figure writes "I see you" on the back of the car where The Liars are.

A.D. steals the files that Jessica had of Aria and Noel, drenching the latter with alcohol and lighting a match to burn it.

The DArkest Knight

A.D. pulls an unconscious Jenna from the abandoned school for the blind putting her in the back of a van and takes off their mask. Jenna asks them who they are and whether they shot Spencer. When they do not answer, she gasps that they must be A.D. as the hooded figure starts the engine.

Trivia

 * This figure is more interested in finding Charlotte's Killer, rather than tormenting The Liars.
 * This figure doesn't wear The A-Team's signature black hoodie and gloves until the night they kidnap Hanna with added night vision goggles to boot.
 * The main suspects of the fandom are Wren Kingston, Melissa Hastings, and Lucas Gottesman.
 * Unlike Mona and Charlotte, this "A" is far more serious and violent, ready and willing to murder people.
