- "Esperanza died five years ago. I'm only Ultraviolet now!"
- —Esperanza Garcia to her cousin, Allegra Garcia[src]
At some point, She got into a fight with her cousin Allegra, who wanted out of Esperanza's gang. When the Particle Accelerator exploded and surged across Central City, she and Allegra were blasted by waves of the dark matter giving both the same powers of Electromagnetic manipulation. However, Esperanza fell into a vegetative state making her cousin think she was dead since she couldn't feel her pulse. Esperanza was later taken out of the custody of CCPD by an unknown organization, who presumably cared for her during her recovery. Following her waking up, the group began training her to be an assassin.
In 2019, Esperanza, now going by Ultraviolet, attacks the Central City Police Department to kill her cousin in order to keep the fact that she was alive a secret. She was defeated by the Flash and sent to Iron Heights.
Working with Remington Meister
Sometime later, Esperanza was released, thanks to the influence of powerful friends, and went to work for Remington Meister, tasked with ensuring the auction for The Ring of Fire went smoothly. Meister has her keep an eye on Barry Allen and Ralph Dibny after the two question Meister. When their system detected the presence of the Flash, she captures him and ties him up with Ralph, who'd been caught by Meister. While the Flash is surprised to see her free, she and Meister unveil a laser which will kill them once Central City is annihilated by the Ring of Fire.
Later, during the auction, they were interrupted by a drunken Barry Allen, who she is tasked with escorting out. Barry, believing it to be in "Mortal Kombat", distracts her, smashing a bottle on her head. During the fight, Barry a the spotlight on her, knocking her out. She was presumably arrested along with Meister.
After being hit by the particle accelerator explosion, she thinks that herself as Esperanza Garcia is dead.
Esperanza has some honor when fighting, as seen in her battle with the Flash. When her waves left him on the floor, she waited for him to stand up before attacking him again.
Allegra sees her cousin as the darkness to her light.
Powers and abilities
- Meta-human physiology: After Esperanza was blasted by dark matter from the particle accelerator explosion, this altered her DNA and supercharged her cells, giving her access to her powers.
- Electromagnetic wave manipulation: Just like her cousin, Esperanza is able to manipulate a range of different frequencies and wavelengths of radiation on the electromagnetic spectrum.
- Electromagnetic vision: The entire electromagnetic spectrum or most of it is visible to Esperanza. She can tune her vision to interpret the various ranges of energy. She can see radio waves (which include AM, FM, and TV frequencies) radar, infrared, visible light, ultraviolet, power waves, x-rays, and gamma rays.
- Radiogenesis: Esperanza is able to generate multiple forms of radiation.
- Electromagnetic pulse emission: Esperanza can emit a surge of electromagnetic energy, which can disrupt all technology nearby. Esperanza used this to interrupt Cecile's cellphone and to shut off the power at CCPD.
- Ultraviolet blast: Esperanza can release blasts of UV radiation from her hands. She used this to assassinate Salvatore and the eye-witness who ID'd her cousin by a tattoo they share. She was able to hurt Barry Allen (under the persona of the Flash) who couldn't outrun the UV blasts as Ultraviolet light travels at 186,000 mph per second, which is 80x faster than Barry's top speed.
- Peak of human physical condition: As an assassin, Esperanza is in top physical condition with fast reflexes, demonstrated when she dodged gunfire from Joe West. She is strong enough to knock Barry Allen out with a single kick. She was also unfazed from getting hit in the face with a glass bottle.
- Acrobatics/Free-running: Esperanza is very agile and able to descend from large heights.
- Expert hand-to-hand combatant/Martial artist: Being a trained assassin, Esperanza is a highly skilled hand-to-hand combatant and martial artist. She was able to defeat a squad of armed police officers in a matter of seconds and could easily overpower Barry in a fight. Her style seems to be comprised of boxing, taekwondo, muay thai, judo, and akido.
- Bilingual: As a native Mexican, Esperanza speaks Spanish fluently, in addition to English.
- Stealth: As a trained assassin, Esperanza is highly experienced in stealth tactics.
- Ultraviolet suit: Esperanza wears this suit when operating as Ultraviolet.
- Voice modifying mask: Esperanza wears this half-mask as Ultraviolet to cover her lower face and disguise her voice in order to conceal her identity.
- When facing off against Esperanza again in "", Barry Allen jokingly noted that he loves Mortal Kombat, most likely referencing the fact Esperanza's Ultraviolet suit and overall look is very reminiscent of the character Skarlet from the Mortal Kombat series.
Behind the scenes
