"She's everywhere and nowhere."

- Mona about Red Coat

Biography
She has complete control over the A-Team, calls the shots, and directs the other "A"'s working for her. Red Coat is the Main "A", as she is the most important "A" on the A-Team, and the most ranked. Before recently, there had been no information on this character. The only thing clear was that she  wore a red coat, and she was part of the A-Team.

Red Coat's character first came to light at the end of the season 2 finale of Unmasked. After it was revealed that Mona Vanderwaal, Hanna's best friend, had been the elusive A|"A" person tormenting the girls for months. At the end of the episode, she is taken to Radley Sanitarium, where she is then visited by someone in a red coat, similar to that of Vivian Darkbloom's. Mona looks up to her and says: "I did everything you've asked me to", revealing that even A herself is working for someone of higher ranking.

Throughout season 3, new information has sprung about this person. Red Coat has been revealed to be a she, has a petite frame, and has long blond hair. It has been revealed that in the season 3 finale of "A DAngerous GAme", the identity of the stranger in the Red Coat was Alison DiLaurentis, although it is unclear what her true intentions are, as it seems she hates the liars, she also saves them from potential death mulitple times.

After she knocks Spencer unconscious and put her in her car to go the hide out but Mona gives Spencer an "offer that she can't refuse to either join the A-Team, or die. After the fiasco of the episode at Lookout Point and we see when Mona is taken to the police station before she goes to Radley Sanitarium but she says in a monologue of They think it's over. Loser Mona's going to the nuthouse and those precious liars are going home to leep with their windows open and  their doors unlocked... Don't they know that's what we 'want!' It becomes confirmed at this point to A is about a team of people.

At the end of this episode when we see Mona sitting in her bed at the Radley Sanitarium.but 'Big A' was a visitor and was wearing a red trench coat similar to Vivian Darkbloom's.

In the same episode, we also see Mona, (most likely) talking to the Red Coat on the phone since Mona learns from the other person that there is a "change of plans". Since Red Coat is usually the one planning out all of the "A" schemes, it seems as if it really was her.
