Linda Park (Earth-2)

Linda Park is a former small-time thief who, after exposure to Harrison Wells' particle accelerator, gained the power of photokinesis and became a supervillain known as Dr. Light.

Linda was forcibly brought to Earth One by Zoom and extorted into killing Barry Allen/The Flash. Linda instead tried to fake her death by killing her Earth One counterpart, then left Central City when this failed.

Early life
Little is known of Linda's early life other than that she was a small-time thief.

When Harrison Wells' particle accelerator exploded underground sometime around December 2013, Linda was one of the many exposed to the dark matter, which transformed her into a meta-human with the power to utilize beams of starlight. Using these powers to further her own thievery, she began using the name "Dr. Light". Linda had at least one encounter with "Jay Garrick/The Flash", but never killed anyone.

Forced mission on Earth One
In November 2015, Linda was brought over to Earth One by Zoom to kill The Flash of Earth One. Linda was uninterested in carrying out this order, bu nonetheless terrified of Zoom, so she began robbing banks to get enough money to flee into hiding. When Linda was robbing Central City National Bank, Cisco Ramon got a vibe and alerted Flash immediately. The Flash arrived, but Linda used her powers to create a sound wave, sending civilians flying through the bank and forcing Flash to save them, allowing her to escape. Linda proceeded to rob another bank, but the Flash arrived moments later and confronted her about Zoom. The Flash knew Zoom brought Linda to Earth One to kill him, and told her she didn't need to as they can help her. Linda scoffed at the idea and almost attacked Flash, but he managed to talk her out of it and tried to negotiate with her. Linda removed her mask and revealed herself. The Flash was shocked and addressed her by her name, startling her. In response, Linda shot out a large blast of light energy, temporarily blinding the Flash.

Linda found out about her Earth One counterpart and stormed into Central City Picture News, blasting a van where Caitlin Snow and Jay were staking out the place. Inside, Linda confronted Earth One Linda and tried to blast her, but Eric Larkin intervened and Linda accidentally killed him instead. Iris West shot off her mask, revealing her identity. When Jay attempted to intervene, she fled.

Desperate, Linda attempted to flee the city at the South Plaza train station on Platform 15. The Flash arrived and Linda begged him to let her leave. The Flash refused because of Larkin's murder, but Linda professed it was an accident and killing her Earth One counterpart is the only way she can escape Zoom, unless she kills and fights The Flash. The Flash eventually began using speed mirages to distract Linda, though she initially she uses her powers to foil him. Eventually however, The Flash manages to sneak up on Linda and knocks her out with a punch. She was promptly detained in the Pipeline, to be used by Team Flash as bait to lure Zoom to S.T.A.R. Labs.



Escape
The Flash talked to Linda in the pipeline, who told him that she didn't want to kill anyone under Zoom's orders and was only trying to kill her Earth One counterpart to fool Zoom into thinking she was dead. Upon persuasion from The Flash, Linda seemingly agreed to help Team Flash capture Zoom.

Later however, when Cisco came by to deliver some food to her, Linda used her ability to turned herself invisible and managed to trick him into thinking she had escaped, prompting him to open her cell door. Using her powers, Linda overrode the security system at S.T.A.R. Labs and quickly fled, with only her helmet and suit remaining in the cell.

Linda's whereabouts remain unknown after Zoom and his army's defeat but given how she doesn't seem to be participating in any criminal activities, it can be assumed she is living a new, low-profile life on Earth One.

Personality
In stark contrast to her Earth One counterpart who is a strong willed, hardworking, level headed and kindhearted reporter, Linda is an extremely paranoid and easily startled low life thief. She exploits her gofts for personal gain, such as robbing banks. However, Linda did have a moral stance as she never killed anyone before her abduction and arrival to Earth One, and didn't even want to kill The Flash when told to do so. However her fear of Zoom eventually made her snap and she tried to kill her doppelgänger in a desperate attempt to fake her death, which accidentally caused her to kill Eric Larkin. When the Flash tracked her down Linda resorted to her original orders; to kill the Flash; and attempted to do so but still expressed regret over killing Larkin.

Linda seems to have a slight ego as when she first meets her Earth One doppelgänger, she called her "gorgeous", meant as a compliment to herself.

Powers

 * Meta-human physiology: After Linda was struck by the energy of the Particle Accelerator explosion on Earth Two, this altered her DNA and supercharged her cells, augmenting her physiology into beyond peak human condition.
 * Photokinesis: Linda has the power to shoot out high energized blasts of light as hot and luminous as a star. These blasts of light are able to blind someone temporarily, and possibly permanently, as well as cut through metal. Due to her light based powers, it is possible she can hit something moving as fast as the Flash if she aims properly as her blasts would move at the speed of light.
 * Hacking: Due to her powers, Linda can tap into any computer system with fiber-optic cables. This power seems fairly advanced since she was able to override the security systems at S.T.A.R. Labs, which is no small feat.
 * Invisibility: Linda has the ability of turning herself invisible, probably by bending the visible light around herself and leaving her own body unseen. However, she can't turn any of her clothes invisible, forcing her to remove them to utilize this power effectively.

Abilities

 * Expert thief: Linda was a successful small-time thief, even before she became a meta-human.

Equipment

 * Dr. Light suit: Linda wore a suit as her alter ego, Dr. Light.

Behind the scenes

 * In the DC comics, there are two different versions of Doctor Light; Arthur Light and Kimiyo Hoshi. However, in the Flash universe, Dr. Light is an alternate version of Linda Park.
 * Even though Linda is the second case of gender-bending a 'villain', she's the first case to be a composite character with her gender alternative from the comics.
