Rachel Rayne (Guardian Arrowverse: Earth-1)

Rachel May Rayne {later known as Rachel Rayne-Merlyn} (born 1995) is a resident of Star City and a member of Team Arrow. Rachel was born into the socialite lifestyle due to her father being CEO of the leading real-estate company in Star City. Due to her sister's friendship with Oliver and Tommy, Rachel grew up and became friends with Elena, Thea, and Selena. At the age of fifteen, she came out as a lesbian and moved in with her sister after her parents didn't fully accept her sexuality. She later becomes the go-to computer expert and hacker for Team Arrow and, along the way, falls in love with Selena Merlyn/Lunar Wolf. Rachel is later given the codename Oracle.

Personality
In her younger teen years prior to the series, Rachel was a bit impulsive, yet kind, caring, selfless and moral. After her then-girlfriend, Corey Seldon was arrested by the F.B.I. and (apparently) committed suicide before her sentencing, Rachel decided to change her ways, turning her into the responsible individual she is today.

Rachel is an intelligent, ambitious, hard-working, and tech-savvy individual who is highly confident in her computer skills. Though she doesn't go looking for trouble, Rachel is also not one to back away from danger, particularly when there is a mystery waiting to be solved; for example, she accepted the task of investigating Moira Queen's apparent blank notebook, despite Walter Steele's warning that the last man who looked into his wife's affairs died suspiciously the next day.

Selena Merlyn/Lunar Wolf
Since their older siblings dated at one point, Rachel and Selena have known eachother for years prior to the series. After Selena's return and Rachel comfortable with her sexuality, the pair soon realized they had deeper feelings for eachother.

Andrea Rayne/Artemis/Arctic Fox
Rachel looks up to her older sister and loves her dearly. The two are close as sisters could be and care about eachother's safety and well being. When Andrea becomes the vigilante known as "Artemis", and the team later adopts a 'no-killing' policy, Rachel fights for her sister to stand by that, no matter the cost. Even when she was taken hostage by Count Vertigo, Rachel begged her sister not to kill him, but Andrea made the choice to anyway.

Barry Allen/The Flash
Upon their first meeting, there was a certain spark between Rachel and Barry and for a while it appeared things would turn romantic for the two of them. However, when Barry kissed Rachel, it was clear to her that she wasn't bi-sexual and strictly attracted to girls. This didn't damage their friendship in any way and Rachel and Barry continue to be great friends.

Cisco Ramon/Vibe
Both being the tech guru's of their respective teams, Rachel and Cisco have a great friendship.

Abilities

 * Genius-level intellect: With an IQ of 170, Rachel has an exceptionally bright mind and is one of the most intelligent individuals in the multiverse. She's regarded as a child prodigy, able to engineer computers by the age of seven. Rachel graduated early from the Starling City Institute of Technology at the top of her class with a dual master's degree at the age of 17.

Weaknesses

 * Paraplegic: After being in a car accident with Andrea, caused by colliding with one of Slade's Mirakuru soldiers, Rachel's spinal cord was permanently damaged, rendering her incapable of walking. However, with an implant created by Curtis Holt and several weeks of physical therapy, she was able to regain her mobility.
 * Hacking: Due to Rachel's spinal implant, she is presumably vulnerable to hackers, who would be able to deactivate the device.

Equipment

 * Implantable bio-stimulant: After being paralyzed in a car accident in the second season, Rachel had a bio-stimulant designed by Curtis Holt implanted into her spine, which allowed her to walk again.
