- Nora West-Allen

Nora West-Allen, nicknamed XS by Iris West-Allen, was a meta-human speedster and a time traveler, as well as the daughter of Barry Allen and Iris West-Allen from the future. After going back to the past to finally meet her father, Nora became a part of Team Flash, working alongside her parents and their friends. Unbeknownst to the rest of the team, however, Nora is working with Eobard Thawne, imprisoned in 2049, on a mysterious agenda regarding the timeline.

According to a version of Thawne who changed the Flash's fate in 2000, Barry's daughter was supposed to be Dawn, presumably referring to Nora in the original timeline. Among her early pseudonyms suggested by Lia were Lady Flash, Flash Woman, Femme Flash. A later version of Thawne has nicknamed her Little Runner. Her cover identity as a villainous speedster was Jenni Ognats.

After Team Flash defeat Cicada by administrating the cure to her younger self and destroying her uncle's dagger, she was erased from existence as a new timeline began to set.

Previous timeline
According to Eobard Thawne, the daughter of Barry Allen and Iris West-Allen was supposed to be named "Dawn". Upon meeting Nora herself in 2015, Eobard realized she was Barry's daughter and asked if her name was Dawn. When Nora corrected him, Thawne realized that his actions in the year 2000 had changed the timeline, inspiring the West-Allen couple to name their daughter after Barry's late mother.

Early life
Nora was born to Barry Allen and Iris West-Allen sometime between 2019 and 2024 in Central City. She was named in honor of her late paternal grandmother, Nora Allen.

In 2024, Barry disappeared after a battle with Reverse-Flash and never returned, leaving Nora to be raised solely by her mother. Sometime after this incident, Iris secretly had a power-dampening chip implanted in Nora to keep her inherited speedster powers hidden, also asking family and close friends to stay silent about them. As a result, Nora remained unaware of her meta-human powers.

As she grew up, Nora was given the nickname "XS" by Iris due to the former's tendency to do things in excess.

While Nora didn't remember her father, she nonetheless idolized Barry. Following his disappearance, Nora's relationship with her mother became tense as Iris struggled in the aftermath of losing Barry and refused to talk with Nora about him or their past. Nora also took much of her anger over her father not being around out on her mother. As a result, Nora spent a lot of her time in the Flash Museum where she studied Barry's adventures.

In 2032, when she was a child, Nora visited the Hall of Villains in the museum for the first time. One of the villains mentioned was Cicada, a meta-human serial killer who both Team Flash and their allies failed to capture. Upon learning this, Nora grew very terrified of Cicada, even more so than any other villain in the Flash Museum.

One day in the 2030s, Nora ran away from her home to the Central City Police Department then to the Flash Museum. There, Nora bought a comic and an action figure of her father as the Flash. Interested, she read the comic while holding the action figure. Nora then visited the Hall of Villains section of the museum again. There, she watched a video that explained that Cicada had killed many more citizens than Zoom, Savitar, the Thinker, and Red Death. Nora grew even more scared of Cicada. Nora's mother, Iris eventually found Nora and told her to not run away from home again, and Nora got angry at her mother, saying that she wanted to visit the Flash Museum because of her dad. Nora then dropped her action figure and then her mother picked up the toy and gave Nora a hug, saying that she loved Nora.

Nora graduated from Central City University with a 5.6 GPA and became a forensic scientist. Following in Barry's footsteps, Nora joined the CCPD, working alongside Lia Nelson.

In one case of chemical theft, the crime scene left Nora to deduce that the incident could only be caused by a speedster, when talking to Lia about her theory, Lia dismissed it as an obsession from Nora and remembered Nora's obsession with "Cicada", after Lia argued that no speedster has appeared since a devastating crisis, Nora saw Speed Force trails in her software, she went to the Flash Museum to research about the variants of the Speed Force until the curator announced that the museum was closing for the day, when Nora and Lia were investigating the case, Godspeed hit her with electricity, after being sent to a hospital, the doctors extracted the power-dampening chip her mother implanted in her, Nora discovered that she had powers and used them to try to be a hero, but accidentally ruined the arrest of two criminals.

After searching a way how to stop a speedster, Nora decided that she needed the help of another speedster so she went to Iron Heights Prison to interrogate Eobard Thawne, Eobard was able to tell that Nora was a speedster due to clues over her body but before she could ask for his help, she got interrupted by a guard, Nora and Lia resumed their investigation by breaking in Stagg Industries to find the last chemical that Goodspeed needed to make V9 but he shows up shortly after they arrive and after a brief fight with Nora, he kills Lia. Back at CCPD, Detective Curtis told her that they found Godspeed's DNA inside Stagg Industries which lead them to discover that his real name is August Heart, Nora was then able to convince Eobard Thawne to use his transmitter to help her stop Godspeed, Eobard sends her to the Tracy Brand Building to get the converter that would stabilize the Godspeed's Velocity 9 serum. Godspeed shows up and Nora is able to stop him until he uses a dose of his V9 serum to remove his Power-dampening cuffs. Godspeed chases Nora through the city so Eobard tries to teach Nora how to phase but she fails and hides instead.

Eobard then came up with a plan to neutralize Godspeed's V9 by getting him to run in front of Central City Citizen Media's satellite wave. After August was arrested, Nora asks Eobard to train her but Eobard tells her that he is already on a death row. However, Eobard asks who leads her to search in the Time Vault in S.T.A.R. Labs. She finds Gideon there, who already knew her and Gideon reveals to her that her father was the Flash and showed her Barry's final message.

As a result, Nora became estranged from her mother, feeling that Iris took away her choice to be a hero like her father, Eobard began passing on his wisdom to Nora, in which she honed her powers like Barry. She became known as the "Fastest Woman Alive", a homage to her missing father.

Visit to the past
Thawne taught Nora how to travel through time using the Speed Force. Before her travel to the past, she created a language to use it to write events of the early 21st century on her journal and to inform Thawne about some of these events. After this, she traveled 30 years into the past to late 2017. She awkwardly greeted her father at his wedding to her mother. Nora informed him that she felt the wedding would be "one for the ages". Barry asked if they knew each other, to which Nora quickly replied that they didn't and that she was no one special. Before walking away, Nora told Barry to make sure to say "I do".

Nora reappeared sometime later in CC Jitters after the defeat of the Trickster and Prank. She excitedly paid for Ralph Dibny and Cisco Ramon's drinks whilst babbling intellectually about helping others, much to their confusion. Afterward, Nora wrote in a journal, using the same language that she developed before her first time travel.

Nora later returned to Jitters to meet Harrison Wells and Caitlin Snow, unbeknownst to them. She knocked over her Killer Frost drink at their table on purpose and immediately apologized, claiming to be nervous about an upcoming meeting with some new people. After Nora babbled about Jitters, Caitlin reassured her that it was fine and hoped her meeting goes well. As she and Harry left, Nora became serious and muttered that it did.

Nora later appeared as a delivery girl at Barry and Iris' apartment, where her Papa Joe West and Mama Cecille Horton were having their baby shower. Nora told Cecille that the baby was due in 21 days and gave her and Joe a diaper bag, claiming it was a gift from "someone who cares". After giving them the gift, Nora spotted her mother and disappeared. She then ran away at super-speed.

Afterwards, Eobard urged Nora to assist her father in destroying the S.T.A.R. Labs satellite on the day of the Enlightenment. She traveled to 2018 and altered the timeline, making sure the satellite was properly destroyed. After helping her father, Nora saved Spencer Young from falling debris. Spencer then tried to ask her for a selfie, but Nora sped off. The next day, Nora went to the West house, where Team Flash was celebrating the birth of Jenna West. Nora introduced herself to Team Flash, revealed she was Barry and Iris' daughter from the future and claimed she "made a big, big mistake".

Helping Team Flash
Nora mentioned that she knew everyone on Team Flash before stating that her mistake was helping to destroy the satellite, which somehow kept her from going fast enough to open a time portal and that they were the only ones who could help her. She was brought to S.T.A.R. Labs where she ran in the speed lab before awkwardly starting to talk about the future to her parents—right before they stop her. Caitlin then took a sample of Nora's blood while Cisco put a device on her to test her connection to the Speed Force, and she continued to run in the speed lab.

A short time later, Nora ran to the Central City Police Department to see what her father was up to. Noticing how behind he was on his CSI work, she offered to help him look at the cases. Although he was doubtful, she began to work on a case, much to his annoyance. The case she had then caused Barry to bring up ice cream, which caused Nora to start describing the ice cream made at the Mason Family Ice Cream Shop in Happy Harbor, Rhode Island. They both noted that it's their favorite dessert. Right after Barry told her to not mess with the timeline, a radio then alerted them of a meta-human attack, and Nora went to Cisco's apartment and grabbed the original Flash suit for Barry to wear. She tried to tag along but was told to stay. Nora ran after him anyway with the intention to watch and excitedly sees Gridlock. Though she just decided to watch, she ended up distracting Barry, and he is sent flying into the air. Nora ran after him where he landed in the water and she expressed her apologies.

They returned to S.T.A.R. Labs and Nora believed her parents to be mad at her and begged Iris to not say disappointed. When Caitlin asked how she knew who Gridlock was, Nora talked about the Flash Museum which listed all the fights the Flash had and that she studied all of it. Nora then went with Iris to Jitters with the former commenting on how much cooler Barry's lightning bolt is than Lightning Lad's and wondering when he'll be back. Iris told her not to worry and that in the meantime, she's gonna try to get to know her daughter. Iris began asking questions about Nora and their family with Nora revealing she's a CSI and that they don't spend a lot of family time. Nora then asked if Cisco and Caitlin needed help and they both returned to S.T.A.R. Labs where she was excitedly commenting on wearing the tachyon prototype Barry used to when he first met Supergirl. Barry and Nora attempted to return the latter to the future but was rejected by the wormhole, as Nora had equipped a device that harnesses negative tachyons on demand. She revealed to Barry the real reason why she returned to the past and confessed her plot, to stay in the past for a while, to be with him.

Nora later helped Barry and Wally phase an airplane that was about to crash because of Gridlock. Nora bonded with her father as days past and both became close. She somehow also became Barry's trainee for she wanted to become a great speedster like her father.

Meeting Cicada
She often helped Barry stop meta-humans to impress him. They both apprehended Block, a meta-human stealing high-tech weapons. When Team Flash first encountered Cicada, Barry, Ralph, and Cisco tried to stop him but he overpowered the trio. Barry was almost killed but thanks to Nora, who shouted "Dad!", seemingly affected Cicada's emotions, which stopped him from killing Barry and later disappeared.

Back at S.T.A.R Labs, Nora explained that Cicada was never caught, not even by Green Arrow, Supergirl, the Legends, or the League. She also realized the future was altered when she helped her father destroy the satellite. Cicada's hunt for the meta-humans raged on, as he became more dangerous for Team Flash to handle for he wanted to kill Vibe. His hunt for Vibe became very threatening when he tortured Joe for the information about Vibe. At last, Vibe stood against Cicada and were both transported into a snowy forest. Barry immediately ran to aid a wounded Cisco, whose powers were dampened by Cicada's dagger. But when Barry came close to Cicada his powers were also negated. Barry fought Cicada in hand-to-hand combat but lost again. In S.T.A.R. Labs, Nora used the speed force to figure out how to protect Cisco from Cicada. She headed to the battlefield and threw a reactor to Cisco to throw at Cicada but it reflected back to Cisco, which made a huge explosion. Fulfilled, Cicada instantly flew away, while Barry, who thought that Cisco was dead, mourned his friend's death but a minute later a breach appeared. Cisco came out of the breach, exhausted while Barry hugged him. Cisco thanked Nora for saving him from Cicada.

Reconciliation
Team Flash battled Spencer Young/Spin, a blogger who aspired to become famous by hypnotizing people and creating "news" for her to report. Barry and Iris assigned Nora to spy on investigate whether or not Spencer was a meta-human, but after Spencer complimented her, Nora started to flirt with her instead. Iris interrupted and subtly urged Nora to check her meta-human awareness app, which came out negative and caused Spencer to leave. Nora grew irritated when her mother still insisted she stay away from Spencer and revealed they're estranged in the future because Iris secretly implanted a power-dampening chip in Nora when she was young to suppress her superspeed, which the former didn't discover until six months ago. Later, Spencer lured the Flash and XS to a stadium, where she hypnotized XS into trying to kill The Flash. XS tried to phase her hand through the Flash's chest but was knocked out by Iris with a speed-dampening gun. The Flash then captured Spin. Team Flash discovered Spencer's powers came from her phone, which was converted into meta-tech during the Enlightenment. Afterward, Iris tried to apologize to Nora for what happened between them in the future, suggesting she might have had a good reason for implanting the chip. However, Nora believed that her mother only wanted to control her. Barry sided with Iris, stating that everything she does is for her family's protection. Angered and betrayed, Nora moved out of her parents' apartment and stayed with Joe, Cecille, and Jenna at the West house.

Two weeks later, Nora helped her father stop an art thief but nearly hurt some civilians by causing the thief's motorcycle to crash. When her parents scolded her for skipping out on training and being reckless in the field, Nora lashed out at her mother, claiming all she does is talk down to her from behind a desk. Nora later went home and complained to Cecille about Iris. Cecille firmly stated that Nora should respect her mother and put her to work doing household chores in exchange for stories about her father, including an adventure about Barry encountering Grodans. That night, Cecille told Nora a final story about Barry helping a boy who lost his parents eventually smile again. Nora was deeply moved but then realized the story was actually about her mother helping her father in the aftermath of his mother's death. Cecille revealed all of the stories were about Iris and pointed out that Nora projecting her anger onto the past version of her mother is preventing her from seeing the person Iris is now. She gave Nora a scrapbook with more information on Iris. Later, Nora got an alert that her father had been kidnapped by Rag Doll and rushed to save him, only to witness Barry being pushed off a building and Iris jumping after him to unlock his power-dampening cuffs, much to her amazement. Afterward, Nora complimented Iris on her accomplishments as a journalist and apologized for her initial harsh demeanor, making amends with her mother.

In the following week, Nora, Iris, and Sherloque come looking for the piece of the Satellite that injured Cicada and she managed to find it in water. Later that day, she went to fight Icicle with the rest of the team but was unable to fight in the cold temperatures so he got away.

The next week, she and Barry went to a Mercury Labs to retrieve a generator before it was struck by lightning as a lightning strike hitting the generator would have blown up a whole block. When Barry got struck by lightning, Iris told her to make an electrical shock to bring him back from the dead. She and Barry later went to Iron Heights Prison to investigate if Mark Mardon escaped but they were interrupted when his daughter broke in to kill Mardon. However, Barry managed to bring him to the pipeline. The next time Jackam attacked, Nora was able to save Barry from getting hit by another lightning strike. When Jackam appeared at an airport and attempted to kill civilians, Nora brought the Weather Wizard Wand so that Barry could use it to counteract Jackam's lightning.

Fight against Cicada and second thoughts
Later, Nora developed a plan to stop Cicada which involved her and Barry time traveling to gather the required items. So, they first traveled to Barry's final battle against Savitar. After a Time Wraith appeared, Barry distracted it so Nora can retrieve a piece of the armor. They next traveled to when Zoom stole Barry's speed for the transmitter, which Barry obtained from Harry. Just as Barry and Nora were about to leave, Zolomon discovered them and gave chase before being stopped by the time wraith. However, this caused Barry and Nora to travel to an unknown point in time which damaged the transmitter. Nora convinced him to ask Eobard Thawne for help. Despite heavy resistance, Thawne fixed the transmitter after Barry convinced him by claiming the former will never get home if he does not. Finally, they traveled to the night of the particle accelerator explosion. In the Time Vault, Gideon rerouted some of the dark matter released by the explosion into the shard and transmitter, and, while they waited for Gideon's system to finish re-calibrating in order to siphon the dark matter, Barry revealed to Nora that Thawne killed his mother. The accelerator exploded, re-calibrating the transmitter and turning it into a power dampener. They then hid it inside a concrete pillar near the hospital's entrance before returning to the present day to confront Cicada there. When Sherloque confronted Nora about the symbols in her journal, she claimed that she made them up in order to keep track of events even if the timeline changes. Nora then transmitted her latest journal entries to a mysterious individual through Gideon and traveled to 2049 to confront Eobard Thawne at Iron Heights Prison.

Nora gets mad at Thawne for hiding the fact that he killed her grandmother. Thawne tells her that he didn't know that she didn't know since her mother should have told her. But since Barry taught her that Thawne only helps himself, he loses Nora's trust and she runs away.

Nora than goes back to S.T.A.R. Labs and picks up her father's blue suit from the loft for Joslyn Jackam's trial and jokes about Barry wearing a green suit to relax the atmosphere before going heading to weather Jackam's trial. At the trial, she saw that Cecille was acting weird because she accidentally felt Jackam's feeling before she recommended that Jackman should get the maximum sentenced. When a car theft was reported, both her and Barry went after the thief who turns out to be a meta that had the ability to disrupt dark matter which made Barry phase constantly. She managed to stable him before bringing him to S.T.A.R. Labs where he was locked in the pipeline until the dark matter effect wore off. Since Barry was unable to testify, Nora was forced to replace him as the CSI. She managed to answer questions about Jackam until she pleads guilty. Back at the lab, she learns that Jackam never made it to prison and because the thief from earlier broke her out. She later finds Jacham who tries to convince Nora that she wasn't involved in her breakout but Nora still didn't believe her and delivered her to the police. In the speed Lab, she discovers that there is no connection between Van Zandt and Jackam and she asks Barry if every criminal stays bad. Barry told her that even the worst criminals like Leonard Snart can become a hero if people see the good in them. Nora than later goes to face Silver Ghost and Weather Witch but failed to convince Joslyn that she was wrong and Raya shot a missile that knocked Nora off her feet. Killer Frost showed up to create an ice wall to stop the criminals but the car phased through the wall. With the help of Cisco, Nora went to the road where the criminals were supposed to be but unbeknown to her, the car was invisible. Just as the car was about to run Nora over, Jackam froze the road which caused Nora to believe that not all criminals are bad.

The next week, Nora was on the crime scene of Carl Bork's murder and deduced that Cicada was on a killing spree. Later when Cicada attacked another former Meta criminal, Nora tries to save the meta, but Cicada breaks her back.

Erased from existence
"Thank you, for everything."

- Nora to Barry and Iris before being erased from existence

Because of the new timeline being created from destroying Cicada's dagger, Nora was erased from existence.

Personality
"It looks like it's a gift from someone who wanted you both to know how special you are. Someone who understands that time is precious and right now is all we've got. Relatively speaking."

- Nora West-Allen to Cecille Horton and Joe West

Like her father, Barry Allen, Nora is a brilliant forensic scientist with an aptitude for science and is a bubbly, excitable and enthusiastic young woman. She highly idolizes her father and aspires to be just like him.

Nora was deeply impacted by Barry's absence throughout her life and struggles with the idea of going back to her time period, where he is not there. She even hindered Team Flash's efforts to send her back home by using negative tachyons so she could spend more time with her dad. Having a lot in common with her father, Nora is a notorious daddy's girl.

However, Nora grew to have bitter hatred towards her mother, Iris West, upon finding out that Iris placed a power-dampening chip inside her so she couldn't use her speed, as well as keeping the truth about her father being the Flash a secret from her, Nora retained her frostiness towards her mother when meeting her in the past; she didn't want to let Iris see her at Jenna West's baby shower, was not receptive when her mother tried to bond with her at CC Jitters, didn't hug Iris as she did with Barry when being sent back to her own time and refused to give her mother her new phone number when Barry bought Nora a cellphone. Nora even frequently subtly insulted Iris' blog and lack of cooking skills, hinting she doesn't even have any respect for her mother anymore. Nora's anger towards her mother also blinds her to reason, as she refused to believe Iris' warnings that Spencer Young was dangerous, which turned out to be true.

Despite the troublesome relationship Nora has with her mother and the non-existent relationship she has with her (missing) father, Nora is proven to have close familial ties to each member of her family, including Team Flash. She appears especially close to Cecille Horton, her grandfather, Joe and her uncle, Wally West.

However, after learning more about Iris from Cecille, including her accomplishments as a journalist, Nora began to realize her mother was a good person deserving of her admiration, upon seeing Iris jump over a roof without a second thought to unlock a falling Barry's power-dampening cuffs, Nora was in awe of her mother's selfless act. Realizing how unfair it was to blame her mother for a decision she hasn't made yet, Nora apologized to Iris for her initial harsh demeanor and the two began to make amends. Nora has begun to bond with Iris, with the two developing a more positive working relationship.

Nora is keen to keep Barry safe and secure so he cannot disappear in 2024, therefore, letting Nora grow up with her father, she was even mad at her father for disappearing, despite not knowing him as a child and wanted to do everything she could to stop that, even begging him to quit being the Flash, his absence has lead Nora to want to learn everything she can about not only Barry but also Iris as well, with things that the Flash Museum cannot tell her. Her trip into the past to defeat Cicada made Nora learn about Barry's potential future as Savitar, who, when is shot by Iris, horrifies Nora. This made Nora realize that she just "wants to know her father" more and not keep secrets or hidden truths between them.

Nora is, at least, attracted to women, although it is unknown whether she is a lesbian or bi/pansexual. This is seen when she expressed an attraction towards Spencer and even flirted with her; Nora even explicitly claimed to her mother, Iris, that she finds Spencer "cute". She also says in her journal "Oh shrap, am I crushing on her?. Yep, totally am. Which is why I hope she's not bad!. Because maybe I'll get to hang out with her sometime".

Powers and abilities
"My name is Nora West-Allen, and I'm the fastest woman alive. When I'm from, 30 years from now, I'm the guardian of Central City. I'm a speedster, just like my dad."

- Nora West-Allen



Powers

 * Speed Force connection/Meta-human physiology: Nora possesses a natural connection to the Speed Force, giving her the powers of incredible speed. She noted that she isn't as powerful or as capable as her father, Barry Allen in using these abilities, as she can only learn so much from her mother, Iris West, Eobard Thawne and the Flash Museum.
 * Accelerated healing factor: As a speedster, Nora regenerates faster than humans do. According to her, normal axon growth rate reaches five millimeters a day in a large nerve, but for her, it is over a hundred millimeters.
 * Bodily vibration: Like most speedsters, Nora can vibrate her body for various effects.
 * Intangibility: By vibrating her molecules at the natural frequency of air, Nora can physically pass through solid matter. Whilst only having learned this when she met with her father in the past, with the help of her father and her uncle, Wally West, she vibrated an entire airplane and all of its passengers to keep it from crashing.
 * Invisibility: Nora can vibrate her body so fast that she can no longer be perceived by the human eye.
 * Electrokinesis: Unlike other speedsters, Nora can produce both yellow and purple electricity from her body, commonly seen when running. After she tapped into the Negative Speed Force, her yellow and purple lightning turned red and purple.
 * Superhuman durability: Nora possesses inhuman resilience, most commonly seen from being unaffected by momentum build-up. She can take attacks and exertion, even survive impacts that would easily kill normal humans.
 * Superhuman speed: Nora can move at such vast speeds, indeterminable to the naked eye. According to herself, she is "The Fastest Woman Alive", which if true, means that Nora's speed already surpasses all other female speedsters. Her speed is proven to be somewhat able to keep up with her father; however, despite this, Nora is not as fast as Barry at his current top speed, without using her unique time regression ability. However, she proved able to easily outrun Godspeed, an impressive feat as he was able to unleash an electric output that was greater than Barry's current top power level (three billion joules); which was a result of the Velocity-9 serum.
 * Superhuman agility: Nora has demonstrated flawless coordination, equilibrium and dexterity, she can change direction with immediate sharp turns without sliding or losing balance and instantly stop running on the spot.
 * Superhuman reflexes: Nora's reaction time is augmented to superhuman levels, allowing her to react to danger and events far faster than normal humans.
 * Superhuman momentum: Nora can generate great amounts of physical force through kinetic energy, simulating superhuman strength, even in a stationary position. Even little exertions from this build-up can generate a tremendous amount of force, able to knock a person out.
 * Aerokinesis: Nora can use her speed to generate air flows on various levels and for various effects. She can create vortexes to extinguish fires by forming it around them.
 * Time travel: The kinetic energy buildup from Nora's speed can allow her to breach the space-time continuum, allowing her to physically enter the Speed Force and travel through time. She first used this ability to travel back to 2017 to meet her father for the first time.
 * Time regression: Nora is able to reverse time around her while running, remaining completely unaffected, such as when she stopped Barry from destroying the falling S.T.A.R. Labs satellite alone.
 * Superhuman stamina: Nora can handle the stresses of extreme racing without noticeable distress, letting her function much longer than normal humans unhindered.
 * Mental link to Grace Gibbons: Nora's time in Grace's memories seems to have left her with a mental connection to the latter's mind, allowing Nora to know when Grace is nearby, and even see things that Grace is seeing.

Former powers

 * Negative Speed Force connection: After being sent back to 2049 by Barry, Eobard Thawne reluctantly taught Nora how to tap into the Negative Speed Force in order to travel back to 2019; thus gaining a connection to it. However, she later gave up her connection to the Negative Speed Force.
 * Eye transformation: After tapping into the Negative Speed Force, Nora's eyes would glow red when she was filled with rage. However, she later gave up her connection to the Negative Speed Force, so this is no longer happening.

Abilities

 * Acrobatics: While distracting Vanessa Jansen/Block in order to tire the latter from overusing her powers, Nora was able to successfully evade all of her attacks, displaying expertise in flips and other maneuvers.
 * Drawing/Sketch artist: Using her speedster powers to preserve quick memory, Nora is a talented sketch artist; she was able to quickly complete a drawing with elegant detail in seconds.
 * Genius-level intellect/Forensics: Like her father, Barry Allen, Nora is very intelligent, having graduated from college with a 5.6 GPA. From a young age, Nora was a keen-minded individual, displaying a natural understanding and quick capacity to learn. Like her father Barry, Nora is a highly capable forensics examiner. From a single glance at the crime scene, she can quickly determine much of the events that transpired. Nora invented the Time language, used to record events regardless of changes to the timeline, which even the combined efforts of Cisco Ramon and Caitlin Snow had difficulty deciphering. Nora also exceeded the expectations of her future's advanced education system, having studied neuro-regeneration in her fifth-grade STEM class. Nora's intellect earned praise from both Eobard Thawne and Harrison Sherloque Wells.
 * Bilingualism: In addition to English, Nora knows the mysterious language that Barry learned when he was trapped in the Speed Force for six months. It was revealed to be known as "Time language", which Nora used to communicate through time with the imprisoned Eobard Thawne. When questioned by Sherloque Wells, Nora claimed to have developed the language herself, which the former was skeptical of.
 * Expert hand-to-hand combatant/Martial artist: Initially, Nora was unable to fight, losing to Godspeed once and ultimately taking him down without combat. Later, Nora has improved and shown to be adapt in unarmed combat as she was able to hold her own against a future version of Grace Gibbons and even briefly push her back, and later her skills have greatly improved, able to quickly defeat two guards without using her powers.

Weaknesses

 * Negative tachyons: Nora used a device pumping negative tachyons into her system, which would slow her down and allow her to pretend like she is unable to travel back to her proper point in the timeline.
 * Power-dampening tech: Nora has stated that, in the future, presumably sometime shortly after Barry's disappearance in the Crisis of 2019, Iris had a power-dampening chip surgically implanted into Nora's body. As a result, Nora's meta-human powers were suppressed all her life, and she only learned about them approximately six months before she'd introduced herself to her parents, meaning she'd have only discovered them shortly before she showed up at her parents' wedding.
 * Cold temperatures: Because speed is produced by a build-up of heat in the target's atoms, Nora is vulnerable to extremely cold temperatures as shown when in battle with Thomas Snow's evil second personality, Icicle.
 * Hyper-metabolism: While having tremendous stamina, a trade-off of her enhanced speed is an equally accelerated metabolism. To which, Nora is required to consume great amounts of nutrients between each super-speed to keep up her strength.
 * Mental link to Grace Gibbons: Nora's mental connection to Grace allows Grace to know when Nora's coming. It also causes Nora to tap into the Negative Speed Force since she feels Grace's anger.

Former weaknesses

 * Negative emotions: Because Nora was required to use her negative emotions, such as fear, hate and anguish to use the Negative Speed Force, the use of the Negative Speed Force corrupted her from the inside. However, she later gave up her connection to the Negative Speed Force so these emotions no longer corrupt her.

Equipment

 * XS suit: Nora wears a protective suit as XS, to hide her identity when fighting crime. It was originally designed by Cisco Ramon for her mother, Iris West, when Barry Allen's powers were transferred to Iris. Nora got the suit from the Time Vault in 2049; when she began acting as a superhero.

Former equipment

 * Rogue suit: As the leader of the new Rogues team Nora used a different suit with a similar purple color scheme, along with her old XS mask.

The first was when Barry came out of the Speed Force and was mumbling "Nora shouldn't be here". The second was when Cisco unscrambled the Speed Force code and unveiled the phrase "This house is bitchin'", which was coined by Nora.
 * Nora is the 11th character in the Arrowverse to have an episode named after her in a civilian sense in some way, after Sara Lance, Felicity Smoak, Harrison Wells, Oliver Queen, Alex Danvers, Zari Tomaz, Harry Wells, Iris West, Ava Sharpe, and Winn Schott.
 * Nora is also the fourth character in the Arrowverse to have an episode title be solely her name, after Sara, Alex, and Zari.
 * Nora is the first female and fourth LGBT character on, following David Singh, Hartley Rathaway, and Rob.
 * Despite being from 2049, Nora doesn't appear to have any restrictions placed on her vigilante activities by A.R.G.U.S.'s anti-meta-human act. This indicates that Zari Tomaz's future didn't come to pass, doesn't exist in her timeline, or for some unexplained reason, Nora is not affected by the legislation.
 * It could also be that because Nora didn't know about her speedster abilities until adulthood and thus wouldn't have acted as a meta-human vigilante prior to discovering them.
 * Another explanation is that A.R.G.U.S.'s restrictions were overturned before 2049.
 * Nora has altered the timeline more than any speedster, changing the timeline at least 54 times.

Behind the scenes

 * Nora can be seen as a composite character or various characters from the comics:
 * In the main DC comics continuity, Nora Allen II of the Justice League: Legacy alternate timeline was similarly a time-traveling meta-human speedster and the daughter of Barry Allen and Green Lantern Jessica Cruz.
 * In the comics, Dawn Allen is the original daughter of Barry and Iris, and is also a speedster from the future who dons a purple suit.
 * This is referenced by Eobard Thawne in the episode in which he mistakenly refers to Nora as "Dawn" and implied this was her name in the original timeline before he killed her grandmother.
 * XS is a speedster and superhero in the 30th Century, and is also a member of the Legion of Super-Heroes. She is the daughter of Dawn Allen and granddaughter of Barry and Iris. Her real name is Jenni Ognats, which as used by Nora as a pseudonym while leading the new Rogues and infiltrating McCulloch Technologies.
 * On the show, Jenna West, whose name is similar to Jenni, is Joe West's second daughter, Iris' half-sister, and Nora's aunt.
 * Nora's personality and motivation for time travel on the show is also similar to that of Impulse, the hyperactive and reckless cousin of XS in the comics who journeyed to the time when Wally West was the Flash from the future to join him as a superhero.
 * However, Nora's motivation is more in line with the Young Justice counterpart of Impulse, who traveled back in time to prevent the Flash from going missing/dying prematurely to stop a bad future timeline from happening.
 * Lia Nelson also nicknamed Nora "Lady Flash", who is a separate character in DC Comics.
 * Nora's catchphrase "Schway" was first seen in the animated series Batman Beyond, where it was used by Terry McGinnis, a teenager from the future.
 * Nora is the first main character of who debuted in  and the fourth to debut on another Arrowverse show.
