Harley Doyle

Harley, a character in the Perfect Match series, is the 2.0 version of your character's Match from Eros. He/She is first seen in Book 1, Chapter 14.

Appearance
The default outfit for male Harley consists of black jeans, a gray shirt inside a matching black jacket with the sleeves rolled up halfway and the collar popped up. The default outfit for female Harley consists of a black dress with a plunging neckline, a choker, a necklace in the shape of a black diamond, and black jeans with a belt. It is presumed that like Hayden, underneath the skin and clothes (at least in the abdomen) is a green and blue circuit board revealing Harley's robotic physiology.

In a cutscene in Book 2, Chapter 9, Harley is seen wearing a suit, with some variations wearing a lapel pin of the American flag.

Personality
Unlike Hayden, who developed a level of sentience and human empathy with the software installed and has willingly choose to live as a human and rejecting the notion that he/she is just a machine... Harley is the opposite and appears to be a more evil version of Hayden. They view your character and their allies as hypocrites for wanting to implant the safety function on Matches because they view it as still being under someone's control. They are also self-centered given that they state they don't give a rat's ass about what happens to the other Matches and views themselves as an equal to Rowan and Cecile.

Physical Attributes
As Harley is physically no more than a collection of wires, circuits, and bolts embedded within a waterproof hardware that closely resembles human skin, he/she is classified as an android. As a machine, Harley is physically stronger than most humans. It is also presumed that like Hayden, Harley is also susceptible to metal detectors.

Mental Attributes
Harley's neural activities such as thought, emotion, memories, knowledge, and personality are preprogrammed by Handlers, adjusting the software as Eros sees fit. As the 2.0 version of Hayden, he/she has been given a few improvements.

Anomalies
It is presumed that like Hayden, Harley is also prone to errors and malfunctions, such as memory lapses, erratic speeches, and sudden shutdowns. These glitches can be caused by electrical disruption in the system (overloaded circuits), such as being hit by a taser, or physical damage to the hardware, such as a car accident.

Your Character
You first meet Harley towards the end of Chapter 14, when s/he was posing as Hayden after Rowan's henchmen knocked you all out. In chapter 15, when Your Character is filling in the rest of the gang and mentions how they took everything made Hayden who they are...and distorted all of it. They have a physical fight in Book 2, Chapter 3, with Harley being defeated by you and Dames. Harley teasingly flirts with you in Book 2, Chapter 5, but you refuse to put up with it. When Hayden brings up as to whether or not Harley can be saved in Book 2, Chapter 7, you can choose to agree, say that it's too late, or that they might not want to be saved. Before you strike them with Nikos' weapon, You can choose to apologize to them, say you're doing it for your friends, or tell them to rot in hell.

Hayden
Hayden is the original model that Harley is based of. Harley considers himself/herself to have better fashion sense than his/her predecessor. In Book 2, Chapter 7, Hayden states their belief that Harley can maybe be saved from Eros' influence. Hayden also tells you that s/he thinks of Harley as a bad sibling/twin, who tried to hit on you more than once.

Rowan West
Rowan gave Harley their name after a relative he once had. Thus far, she/he's the only match as of Chapter 14 who calls Rowan "father." He used Harley to get data and reactions out of Your Character as he continued to play the role of creator.

Cecile Contreras
Cecile is Harley's direct supervisor. As s/he mentions to Your Character, Cecile regards her/him as an "equal." Throughout the series, s/he follows her orders even if irritated or aggravated by Your Character or the circumstances surrounding their interactions. It is possible that Harley has affections towards her, as throughout the book, Harley shows a different persona toward Cecile than s/he does towards Your Character; s/he is protective of Cecile and compliments her in Book 2, Ch. 14., and calls for her after being hit with the stun baton in Ch.15. This doesn't seem to change when s/he overhears Cecile's conversation with Keegan, where s/he learns the truth of Cecile's opinions regarding her/him.
