Harley Doyle

Harley, a character in the Perfect Match book, is the 2.0 version of your character's Match from Eros, and he/she first seen in Chapter 14.

Appearance
The default outfit for male Harley consists of black jeans, a grey shirt inside a matching black jacket with the sleeves rolled up halfway and the collar popped up. 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.

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.

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, Hayden 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 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 he is posing as Hayden after Rowan's henchmen knocked you all out.

Hayden
He/she is the original model that Harley is based of. Harley considers himself/herself to have better fashion sense than his/her predecessor.

Rowan West
Rowan gave Harley their name after a relative he once had. Thus far, he's the only match as of Chapter 14 who calls Rowan father.

Trivia

 * With the reveal of Harley, a 2.0 version of Hayden in Chapter 14, the writers also seem to be paying homage to the BBC America series Orphan Black.
