Barry Allen/Earth-TUD26

## Bartholomew Jimmy Allen

The Flash

**Bartholomew Jimmy "Barry" Allen** (born October 8th, 2003) as **Johnathon Jimmy "John" Waters** is the son of Jimmy and Nora Waters, the youngest brother of Aurora and Alex Allen, the brother-in-law of Joe Garrick, the nephew of Bill Ball and Unnamed Aunt, the cousin of Gia Ball, the ward/turned/future son-in-law of Joe West, the future brother-in-law of Iris and Wally West, the boyfriend/future husband of Jamie West. and the archenemy of Harley Thawne (commonly known as the **Reverse-Flash**).

Barry's mother was murdered when he was 11 years old on March 18, 2014 and the blame was wrongfully placed on his father. He was taken in by Joe and he dedicated his life to proving his father's innocence. After the S.T.A.R. Labs particle accelerator exploded, causing a giant thundercloud to form, Barry was struck by lightning from a cloud, falling into a coma for nine months. When he woke up from his coma, Barry discovered that he had developed superhuman speed and various other abilities derived from it. Using these powers to protect Central City, he began acting as the meta-human superhero known as **the Flash**, initially referred to by the media as **the Streak**, **the Streak**, and **the Blur**, stylized as the "**Scarlet Speedster**".

Barry spent the next several months fighting crime, taking down numerous meta-human villains and other criminal elements, assisted by Team Flash. All the while, he worked with Joe to get Jim out of prison and with Harrison Wells to get faster and develop his abilities. Barry later found out that the latter was the evil speedster Harley Thawne from the future, having stolen Wells' identity, and the man who murdered his mother. In a final confrontation between the two, Harley gave Barry the chance to undo what he did in exchange for assistance in returning to his time. Barry decided against doing this, which ultimately led to Harley's ancestor killing himself to erase Eobard from existence.

## Biography

### New multiverse

#### Early life

Barry was born on October 8, 2003 to Jimmy and Nora Waters, as **Johnathon "John" Waters** as the youngest child.

When he was six years old, Barry begged his parents to take him to a science exhibition in Midway City, but they, unfortunately, got a flat tire on the way. The family's car had to be towed to a garage in Masonville, where they were stuck all day. Barry, his siblings, and his parents had ice cream and French fries with gravy for dinner at a small diner and spent the night watching the local fireworks display. Barry would consider this to be one of the happiest memories he ever had with his parents and siblings.

Barry and his mother would watch Fred Astaire and Frank Sinatra musicals together on rainy nights.

At some point, Barry met Jamie West at school, with whom he became best friends. At the age of 10, Barry formed a crush on her. Jamie's father, Joe West, as well as Jim and Nora, were all aware of Barry's developing romantic feelings.

On March 18, 2014, 4 days after his 11th birthday, Barry ran home from school after getting into a fight with some bullies. Though not being fast enough, his mother assured Barry that he had a good heart, and his father was proud of him for winning the fight. Later that night, Barry was comforted by his mother when he admitted he was afraid of the dark. Nora convinced him he wasn't afraid of darkness itself, just being alone in the dark and wished him sweet dreams.

#### Death of Nora Waters

That night, Barry and his siblings was woken up by a commotion. They went downstairs and saw his mother surrounded in streaks of red and yellow lightning. Barry attempted to reach his mother, but she told him to stay back and amidst the streaks, Barry saw "the Man in Yellow" for a brief moment, and his father urged him to run with his siblings. At that very moment however, Barry and his siblings suddenly found themselves 20 blocks away (because his future self took him away from the Reverse-Flash).

Barry and his siblings returned home in time to see their father being arrested by police, and they were told by their father not to enter the house. They entered, seeing Joe standing solemnly over a body. When he walked away, Barry approached the body and discovered, to his horror, that it was his mother.

Following the ordeal, Barry and his siblings was taken in by Joe, Jamie, and Iris. When Joe and Barry arrived at the West house, Barry was not crying, due to shock. Joe asked Iris and Jamie to show Barry and his siblings to their guest rooms, and Barry told Jamie that his father did not kill his mother, to which Jamie responded that she believed him. Later that night, Jamie found Barry crying alone and comforted him.

After a while Barry and Jamie were always hanging out together. Alex saw that he was smiling, but not as bright as he used too. Aurora noticed that too. They all knew that Jamie and Barry liked each other.

Months down the road, Barry, changed his named from Johnathon to **Bartholomew Jimmy "Barry" Allen**, and his siblings changed their names too, as kids were bullying them at school and they went to a different school in Central City with Jamie and Iris.

Initially, Jim asked Joe to not let Barry and his siblings see him. Not knowing this, Barry kept trying to run away to see his father at Iron Heights, and he was caught and stopped by Joe every time; at one point, Barry called him out for it, telling him that he wasn't his father and that he hated him. Eventually, Barry finally reached Iron Heights before Joe could stop him, and he finally came face to face with his father. Jimmy told him that he simply did not want Barry to see him in prison. Despite this, Barry begged for his father's release, insisting that the man in the lightning was who killed his mother, not Jim. Jim told him that he couldn't help him and asked that he be a good boy and let Joe raise him. Jim was promptly taken away and Barry became more accepting of Joe as his new guardian.

Six months after his mother's murder, Barry was still depressed and became grumpy towards everyone. Seeing this, Joe understood that Barry was acting angry because he didn't want to let the pain of the grief in, fearing his father and mother would be disappointed in him if he did. Joe assured Barry it was okay to let the pain in. Barry finally allowed himself to feel the grief and cried, with Joe comforting Barry and promising that he'd always be there for him.

During the first year that Joe took him in, Barry attempted to impress the former by building a robot with wheels for his science fair project, which nearly set the school gym on fire and hurt his teacher, Mrs. Dumas. In school, Barry was relentlessly bullied by Mason Woodward. Joe noticed this and had Barry spar with Jamie, who easily beat him. Joe then told Barry that if he ever got into a fight he couldn't win, it was okay to run the other way.

At the age of 12, Barry went to a reptile camp, which was paid for by Joe. In 7th grade, Barry decided to mix glycerol with an oxidizing agent for his science fair project, believing he would win if he started a chemical fire. Barry got an A, but was suspended. As a teenager, Barry, according to himself, "lived for danger", including smoking a cigarette once, which was an unpleasant experience.

In high school, Barry attempted tryouts for the football team but failed horribly and made Joe swear to never talk about it again. Barry dated Becky Cooper in high school, though she was apparently a "nightmare" of a girlfriend. When Barry was 16, he and Jamie switched bedrooms so Iris and Jamie along with Aurora could sneak out the window past curfew, which was 8:00 pm at the time. They told Joe the reason they switched bedrooms was that Barry and Alex didn't like the noise from the streets. At one point, The West Girls and the Allen kids took Joe's convertible out for a joyride and ended up crashing it into an oak tree on Fairmont Drive. Without realizing he was the man who killed his mother, Barry idolized Dr. "Harrison Wells" so much that read his biography twice, though he was still left not knowing much about him.

Barry graduated from college with a double major in physics and chemistry. It was with this skill that Barry was motivated to study criminology at Central City University in the hopes of proving that his father was innocent in his mother's murder. Barry was hired for the Central City Police Department by Captain David Singh. Shortly after, around 2023, he was the Junior CSI (later a rookie cop and detective at CCPD) on a murder case in which the victim, Judy Gimlin, was stabbed to death and her husband, Reagan, was the prime suspect, which touched home for Barry. His superior, Detective Ralph Dibny, apparently proved Reagan's guilt by finding the knife used to kill Judy, which contained his fingerprints. Seeing similar circumstances to his mother's murder, Barry decided to delve further into the investigation and tested the knife. The knife actually didn't match the murder weapon used to kill Judy and Barry reported Ralph, who was subsequently fired for planting evidence. This created an enmity between the two.

After a while Jamie joined the CCPD as a cop too, and became Barry's partner at work.

#### Visit to Star City

A year later, in December 2024 when he was 21, Barry arrived in Star City. He wasn't able to initially get a cab as the driver pulled away, and he soon arrived at Queen Consolidated's Applied Sciences Center to investigate a mysterious break-in as a CSI/Detective from Central City with a connecting case, where he met Oliver Queen, John Diggle, Quentin Lance, and Felicity Smoak.

Barry was set up in the division with Felicity's help, unknown to Barry, because Felicity believed that they should have used him as an asset considering his work in forensic science. The two began talking, and Barry began speculating about The Arrow and his background, making incisive observations about why The Arrow wore green instead of black, the type of arrows he used, and how he theorized that The Arrow has partners, particularly someone who had a background in computer sciences; all of this unnerved Felicity.

Barry was astounded when Felicity asked him to help with a blood sample from an arrow she received from the police both by her "connections" from working for Oliver, and the fact that he was working the same case as The Arrow. During that particular part of their investigation, Felicity invited Barry to a Queen Consolidated function, which was actually a party at the Queen Mansion. However, before the results came in, his cover as a crime scene investigator working for the police was blown by Oliver just after he and Felicity began arguing over a news report about the mass particle accelerator.

It was revealed that he was just an assistant CSI and a detective and there was no connecting case in Central City. Barry explained what happened to him as a child and how it had caused him to begin looking into cases with impossible circumstances, in hopes of one day proving one possible, therefore solving his mother's murder and freeing his father. He was later re-invited by Oliver as Felicity's plus one to come to his home, where he was throwing a party for his mother. When there, Barry apologized to Felicity while they danced.

After the party, Barry was contacted by Singh and was told to return to Central City if he hoped to keep his job and revealed the sedative used was ketamine, informing Felicity it should have been easy to track. He tried to catch the soonest train, though missed the last one of the night. He settled down into the train station to wait for the next one in the morning, when suddenly he was hit with a tranquilizer dart to the neck. When he awoke, he found himself in Oliver's base with Diggle watching him and Oliver lying on a table in full Arrow costume. Felicity approached him and asked Barry to save Oliver's life, who was not only poisoned with an unknown substance from the A.R.G.U.S. disaster bunker, but also had been beaten by the robber who had stolen the centrifuge from Queen Consolidated, raided the blood bank, and encountered Oliver as The Arrow while stealing large amounts of ketamine from the bunker.

Barry was able to save Oliver's life by thinning his coagulating blood with rat poison. Oliver was not too pleased with the situation at first, as Felicity had revealed his secret without his permission. However, Barry eventually gained Oliver's trust. He recommended that a mask would be better than the green grease paint he used on his eyes as concealment of his identity. Oliver later asked Barry if there were any side effects to the rat poison he injected in him, and Barry admitted it could cause hallucinations and heavy sweating. After testing Oliver's blood though, Barry discovered that Oliver's hallucinations weren't from the rat poison, and that it was psychological. Soon after, Barry headed back to Central City, but not before leaving Oliver a mask as a parting gift.

#### The accident

On his train back to Central City, Barry encountered Martin Stein and the two discussed physics and Harrison Wells' particle accelerator and how it would change the world. After he got off the train, Barry soon headed back to work, arriving at a crime scene late. He was successfully able to identify the getaway car from the robbery and also grabbed a sample of some animal feces found on the ground, before heading back to his lab to examine the evidence. While processing the feces, he was greeted by Jamie, his partner at work. Barry talked on and on about the S.T.A.R. Labs particle accelerator with her, noting that it provided ideas that were far beyond their current capabilities of science, hence why he was so excited. Detective West approached right as the feces had processed. Barry described the results found, explaining that it had a chemical used only at four different farms around town, suggesting they check them out.

Following this, Barry and Jamie headed to the unveiling and switching on of the particle accelerator. Barry attempted to convey his attraction towards Jamie, and they both asked each other out and they smiled at each other knowing. They began listening to Dr. Wells, who described how the particle accelerator would lead to a much greater future. As they were listening, a thief stole Jamie's bag, along with her laptop inside it. Barry ran after him, He caught up and got into a fight with the mugger. Barry knocked him down and told him how he stole a detective's bag. And he arrested the mugger. Then a cop by the named Detective Eddie Thawne. At the police station, Jamie and Barry mocked Eddie, a new transfer from Keystone City.

Later, Barry headed to his lab, watching the news of the S.T.A.R. Labs particle accelerator, when it suddenly became unstable. As Barry tried to close his lab's rafters due to the worsening storm, he watched in confusion and awe as the liquids around him suddenly levitated, defying gravity. The particle accelerator then exploded and sent a shockwave of dark matter through the city. Seconds later, Barry was struck by a yellow bolt of lightning through a window in the roof. He was sent flying backwards through the already-charged chemicals and knocked unconscious. A red flash of light appeared across Barry's cheek, rising, and then faded away. Barry was quickly rushed to Central City Hospital, where he was kept on life support while in a coma.

For the following five weeks, Barry constantly seemed to flatline. However, it was concluded by Harrison Wells - who had also started visiting him - that Barry's heart was in fact beating too fast to even register on the EKG. When Barry's condition began to worsen he was moved to S.T.A.R. Labs to be closely monitored and was frequently visited by Jamie West. When Jamie came by one day, she received a static shock when she touched Barry's hand.

## Powers and abilities

### Powers

"*I've spent my whole life searching for the impossible, never imagining that I would become the impossible.*"
—Barry Allen to Oliver Queen
* **Speed Force connection/Meta-human physiology:** Barry's powers comes from his connection to the Speed Force, gained when struck by dark matter lightning and exposed to several chemicals. This altered and supercharged his DNA, cells and neurotransmitters. It also augmented his bones, joints, tissue and entire physiology well-beyond peak human condition to easily handle the rigors of his powers. High-level friction, inertia, air pressure, reduced oxygen, vectors, and kinetic impact no longer affect him. After regaining his powers from inside the Speed Force, his connection to and understanding of it improved considerably, with a new-found instinctual control and efficiency, and his improved natural performance unhindered. After Oliver Queen as the Spectre unlocked Barry's full potential, restoring the Speed Force after its destruction, and bringing harmony between the four Forces of Nature, Barry's powers were greatly augmented, reaching the highest known performance of any natural speedster in existence and making him also one of the most powerful beings in the entire multiverse.
	+ **Accelerated healing factor:** Barry's molecules move at accelerated rates, mending damage far quicker and more efficiently than normal humans. Without treatment, most damage heals in under a day with no lingering signs. Even normally permanent damage, like paraplegia, is completely repaired in under a week. His body can break down food more efficiently and, as a result, expels very little waste products that he can exhale through his skin. After the Speed Force was restored, Barry's healing powers further increased, able to recover from the most grievous of injuries in under an hour.
		- **Superhuman immunity:** Due to Barry's accelerating healing factor, he is immune to most types of diseases, illnesses, sickness, drugs, poisons, toxins, etc. He also has greater resilience to radiation than normal humans, only suffering minor burns from it. 2,000 milligrams of horse tranquilizer only momentarily slowed him down until his body burned through it.
		- **Superhuman longevity:** Due to Barry's accelerating healing factor, he ages much slower than normal humans and most other meta-humans. In an erased future of the year 2024, Barry who had been the Flash for 10 years, has not visibly aged. This also enhances his vitality and health, letting him retain his youthful performance for far longer. According to Abra Kadabra, a villain from the 64th century, he is still alive and an active hero that deep into the future.
	+ **Astral projection:** Originally, with the help of a tachyon prototype, Barry was able to project his mind into the Speed Force and communicate with it. Since being taught by Wally, and with increasing both his powers and understanding of the Speed Force, Barry has learned to do this of his own accord. This enables him to contact the other Forces whenever needed.
	+ **Electrokinesis:** Barry can produce yellow electricity, a physical manifestation of Speed Force energy, from his body. It is commonly seen when running to boost his already immense speed to far higher levels. This energy can be focused into his strikes, generating enough force in his strikes to greatly harm super durable foes without any harm to himself.[148] Alternatively, its intensity can interfere with surrounding electronics and overwhelm electric-absorption. He can focus it into specific body parts and produce strong static shocks to electrify a surface or stun targets on contact. Barry was later taught to harness it into his arms to repeatedly hurl lightning bolts to stun or repel enemies. Barry can also absorb electricity from other sources, simultaneously giving him an extra boost when running or throwing lightning.[149] His highest levels are about 5 billion joules (equal the power of five lightning bolts). Being taught by Wally, Barry can generate several constructs to be used in battle; such as swords and shields. These constructs can also levitate to act as platforms. While originally required extensive running to build up his lightning, by 2021, Barry became able to generate his lightning without moving. By this point, he can use it to unleash heavy amounts of destructive electro-blasts in the surroundings, block energy blasts, and even destroy a speedster's powers. His lightning also has electromagnetic capacities, able to act as barriers able to repel entire cars launched at him.[138]
		- **Speed Force aura:** As a user of the Speed Force, Barry can build up a protective aura.[149] This allows him to withstand large gravimetric force and protects the environment from the harm caused by high-speed travel. Barry even built up his aura to be a billion times more powerful than the force of a black hole.[98] This aura also seems to affect kinetic energy and inertia as Barry was able to throw off the Turtle's ability to steal kinetic energy and increase inertia on his victims.[61] This also lets him grab other individuals at high speed without their momentum and kinetic energy ripping them apart and survive impact with objects moving so fast with only minor injuries.
		- **Speed Force sharing:** Barry can expand his Speed Force aura to protect other individuals he carries while moving at superhuman speed. Taught by Jay Garrick, Barry can siphon the speed energy from another speedster to bolster his own speed.[76] After escaping from the Speed Force, gaining a greater an understanding of his power, he can use it in more passive means. By touching others, he can share his energy, letting them move, think, and heal as fast as himself, as this let Jesse recover immediately from a coma. By channeling enough energy, he can share his speed with others, letting them independently move as fast as speedsters without exhausting or affecting their own powers, until they burn through the borrowed energy. Barry is currently the only speedster known able to do this because after spending 6 months in the speed force he was able to absorb enough of its energies to share that energy with others.
		- **Speed stealing/Speed Force siphoning:** He picked up the ability to temporarily steal speed from other speedsters to empower himself and make himself faster for a time.
		- **Energy absorption:** Barry is capable of absorbing Speed Force energy that he injects himself with, for more power.
	+ **Superhuman durability:** Barry possesses superhuman resilience, most commonly seen from being unaffected by momentum build-up. He can take impacts relatively unfazed that would easily kill normal humans. While not invulnerable nor immune to pain, he withstood powerful lightning bolts, concussive shock waves, sonic blasts and inhumanly strong strikes, only being momentarily stunned. After regaining his powers, his resilience has been greatly augmented, quickly rebounding from zombie-Girder's blows, who previously seriously injured him in a single blow. Barry can also remain almost unharmed when falling from certain heights that would easily killed normal humans.
	+ **Superhuman mental process:** Barry's powers also augment his electro-chemical systems, nerve synapses, and brainwaves, and thought process. Granting him an eiditic memory and perfect recall, he takes in and retain information just as fast and efficiently. Even while using his raw speed, he can clearly think, react to events, and perform actions long before normal humans can perceive them. This lets him learn in a small fraction of the normal time, able to change his entire strategy in an instant and familiarize himself with advanced new knowledge within seconds. Flash's heightened mental capacity also lets him change his entire strategy in an instant; able to catch people completely off-guard after familiarizing themselves off his previous patterns. After six months in the Speed Force, Barry's brain activity became over five times faster than it had been previously.
		- **Superhuman perceptions:** Barry's senses are also enhanced. This allows Barry to perceive the world as if it is nearly frozen. He can see and hear normally, even while moving at speeds faster than sound, where this would normally be impossible. Barry became able to easily perceive the attacks of other powerful speedsters. This heightened alertness enables him to instantly read and adapt to the situation. His perception of time, however, seems to vary by his emotional state, as in one instance, when he was waiting to check out from work, he described it as feeling as if it were hours away, while in real time it was merely minutes. Since uniting the four Forces of Nature, Barry's perception can follow the movements of other speedsters as if in slow motion.
		- **Superhuman reflexes:** Barry's reaction time is augmented to superhuman levels, allowing him to react to danger and events far faster than normal humans. When shot in the neck on his blindside, Barry caught the bullet and minimized the damage before it could fully penetrate his skin. He also became able to easily react to the attacks of other speedsters.
	+ **Speed Force awareness:** Due to Barry's connection to the Speed Force, he can sense the presence of other speedster's with such energy in their system.
	+ **Superhuman speed:** Barry can move at such vast speeds. According to Eobard Thawne; Barry's speed is potentially unlimited;[38] he can run across vertical structures and ceilings, over stretching seas, effortlessly catch speeding projectiles, complete his several daily activities in seconds and even casual walking can go unnoticed by normal individuals. While reaching Mach 3.3 on his own and later Mach 13.2 from tachyons, since increasing his Speed Force connection and ability to store-up its energy, Barry has grown tremendously faster. After six months in the Speed Force, his speed reached levels far exceeding all other known super-fast beings, noted by Gideon to be at 2325 miles per second (Mach 10908.82) or 1/80 of the speed of light. After Oliver Queen as the Spectre unlocked Barry's full potential, greatly augmenting his superhuman speed, he became much faster then before. When his powers were restored by reviving the Speed Force, Barry became even faster than Eva McCholloch, whose fractal photons manipulations let her move at a superluminal speed. Barry's speed is further augmented after bringing harmony between the four Forces of Nature.
		- **Aerokinesis:** Barry can use his speed to generate air flows on various levels and for several effects. He can create vortexes to suffocate people or extinguish fires by forming it around them. He can create large and strong tornadoes, able to repel massive targets. Alternatively, he can use this skill to propel himself through the air as a pseudo-form of flying. Later, Iris taught Barry, from her own experience as a speedster, to use this build-up to gather and direct enough water into a tidal wave capable to disperse a giant fire cyclone of over 6000 degrees Fahrenheit.
		- **Interdimensional travel:** Barry can move fast enough to break open portals between dimensions, allowing him to travel to different universes. If desired, Barry can also bring others with him as he did with Harry and Cisco to Earth-2. While originally he could not consciously control this, as his first solo use was done by accident and required assistance to return home, after greatly increasing his Speed Force connection, he can break open portals of his own accord and consciously chose his destination, even into the Speed Force itself.
		- **Speed mirages:** Taught by Harry Wells, Barry can generate illusions of himself to make it appear as if he in many places at once, when in reality he is simply bouncing back and forth too fast for the human mind to perceive the difference. He can create dozens of after-images. This allows him to disorientate enemies and then catch them off guard from appearing to be in more than one place at a time. Barry can also create a mirror speed projection, which he learned from fighting Thawne in 2049.
		- **Superhuman agility:** Barry has demonstrated flawless coordination, equilibrium and dexterity. He can change direction with immediate sharp turns without sliding or losing balance and instantly stop running on the spot. He can jump and run along falling debris and launch himself tremendous distances without build-up. His efficiency of movement can even disassemble an entire speeding car in seconds
		- **Superhuman momentum:** Barry 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 tremendous force, able to knock a person out. He can propel himself to jump tremendous heights and distances. He can also create substantial frictional force with any object he touches, and exert enough force to hurl people into the air. This seemingly negates the weight of his target, able to move about as if targets are frozen, even in mid-air. This also lets him propel and manipulate the targets' flight path, including launched bullet with no loss of force and hurl them through a powerful barrier, followed by a person. He can completely remove the physical force from massive tidal waves, stabilize a giant singularity, or dispel F3 tornadoes by running around them. He can also snap his fingers to ignite flammable gas with the friction. After escaping the Speed Force, Barry can generate enough force to break down the natural durability of a target, as he effortlessly shattered his way out of his meta-human cell. With enough momentum, he can generate a powerful sonic boom through his punch able to destroy a crashing satellite.
			* **Bodily vibration:** Barry can vibrate his body for various effects. This can mask his form from being clearly perceived or distort his vocal cords to disguise his voice. His vibrations can forcibly expel any toxins in him. He can also generate enough heat to recover and stay thermally insulated from extreme cold. Offensively, he can vibrate his limbs to augment his strikes or seamlessly grind through highly solid targets, which he can use to harm or kill a person.
			* **Intangibility:** By vibrating his molecules at the frequency of air, Barry can physically pass through solid matter, even highly complex matter like carbine while in a universe of a different vibrational nature. He can do this with multiple targets, saving an entire moving train with hundreds of passengers, as well as an entire plane with hundreds of passengers with the help of Kid Flash and XS. He can also harmlessly pass through living individuals as he did to escape Atom Smasher's grasp.[1] Barry can also vibrate just parts of his and other bodies, as he phased his hand and Ralph Dibny's arm in order to eject a needle into the latter's elastic skin and give him blood.[6] He can extend this ability to others. During his final fight against Savitar, Barry's efficiency could simultaneously shift the time remnant out of his armor and encase himself in it. He can also pass through one target while simultaneously making harmless contact with another. Alternatively, he can passively phase through the target to incapacitate them.
			* **Invisibility:** Barry can vibrate his body so fast that that he can no longer be perceived by the human eye. When Clifford DeVoe trapped Barry in a force field prison that prevented the latter from phasing through it, Barry did this in order to "trick" Clifford DeVoe into releasing him.[87]
			* **Seismokinesis:** By vibrating at varying frequencies and with different levels of force, Barry can create small tremors to induce extreme amounts of jolt on any target he touches, even disrupt the inter-molecular bonds and cause it to shatter. This can lead to many effects such as molecular combustion upon physical contact with the target. His vibrations can even shatter targets into fragments, as he did to Savitar's armor once inside it. If Barry wanted to, his vibrations could even destroy the world.
			* **Limited Temporal immunity:** Barry was able to reactivate his powers when the Negative Still Force froze him in time, indicating Barry’s powers have grown so strong that he is now partially immune to time related powers.
			* **Time travel:** Barry's speed can breach the temporal barriers, letting him enter different points in time. While originally only accessed by accident when under extreme stress, Barry learned to use it at will and arrive at a destination with pinpoint accuracy. Alternatively, he can enter timelines independent from himself and unaffected by his travels. Regardless of the changes he makes, Barry's powers allow him to retain all memories of the previous timeline in addition to the new timeline and differentiate between them.
			* **Temporal awareness:** Even if Barry is not responsible for any time alterations, he can still remain somewhat unaffected by it; he remembers that John Diggle and Lyla Michaels had a daughter instead of a son in the original timeline. Barry is able to subconsciously detect when other speedsters enter the Speed Force to time travel. After learning that Nora West-Allen had been working with his arch-enemy, he warned his daughter that if she attempted to enter the dimension and travel back to the present, he would feel it.[143] Eobard Thawne later confirmed this to be the case, as it is one of the reasons for him to create the Negative Speed Force to avoid Barry's detection.[150]
			* **Temporal dilution:** By generating enough energy, Barry can move so fast that time essentially slows down relative to him in a large area, to a complete standstill. However, he must continuously concentrate on this action as losing such focus will gradually speed back up again before ultimately returning to its original flow. He can pull others into this state, however, non-speedsters will quickly tire from it as their bodies aren't accustomed to moving at such great speeds. Other speedsters can also remain unaffected by this even provided they retain enough stamina to expand their Speed Force energy. By running around the Earth in the opposite direction with another super fast being at Mach 7, he can generate enough centrifugal force to slow the Earth's rotation and its flow of time.
			* **Temporal regression:** With Barry's ability to shift through time, he can also reverse the flow effects while running at a certain speed, while he remains completely unaffected. Ultimately, he can even grant himself a time do-over, wherein he enters the past and "merges" with his temporal counterpart to be fully immerse in the timeline. This ability is enhanced when he has a Still Force connection, as he was able to not only reverse the progression of Thawne's giant Negative Speed Force lightning tsunami, but undo it entirely so that Thawne would be obliterated by the absorption of his own energy.
			* **Time remnant construct/temporal duplication:** Barry is able to "create" a time remnant by traveling back to moments before his current-self time travels, hailing from a future that no longer exists. This allows Barry to be two places at once, enabling him to interact with the world for two separate actions simultaneously. If desired, Barry can create dozens of time remnants at once.
	+ **Superhuman stamina:** Barry can handle the stresses of extreme racing without noticeable distress, letting him function much longer than normal humans unhindered, showing no change in breathing or pulse after hours of constant exertion. This is due to his augmented physiology, building far less lactic acid or fatigue toxins. Even after running from coast to coast of the country to pick up a pizza, Barry remained unfazed from the prolonged running. However, while his stamina is greater than most speedsters, Barry's reserves are not inexhaustible. Extreme and extended uses of his more advanced powers will eventually drain him.
	+ **Superhuman strength:** Due to the tremendous amounts of Speed Force energy in his body, Barry's physical strength has been heightened beyond that of normal humans, able to carry multiple individuals at once while speeding away with them. When charging his momentum, he could smash through machinery with his bare hands or send opponents flying through the air. He can even stop a speeding car unaided.

### Abilities

"*Barry Allen is just as important as the Flash. Try to remember that. I know I will.*"
—Ralph Dibny to Barry Allen
* **Genius-level intellect/Master tactician/Leader:** A keen-minded individual from a young age, Barry displayed a natural understanding and quick capacity to learn, making it hard for his foster-father, Joe West, to help Barry with his homework by the time the latter was 12. Barry is also very well-read, greatly impressing the award-winning Professor Martin Stein. After Eobard Thawne was defeated, Barry was able to keep Team Flash together and lead them well, to the point that Eobard (as Harrison Wells) made him the new owner of S.T.A.R. Labs. Barry is able to remember everything he experiences with perfect recall; when he saw the Reverse-Flash for the first time in 14 years, Barry immediately recognized him as his mother' Nora Allen's killer, despite being only 11 years old at the time. Barry is also a quick study, as after reading through the various Earth-2 advances in physics, he instantly began making effective use of this knowledge. Barry can communicate with the 5x5 tap code, which he did with Jay Garrick when the latter wore a mask preventing him from talking.
	+ **Bilingualism:** In addition to English, after 6 months in the Speed Force, Barry subconsciously learned a strange language he would scribble in at all opportunities when he came out. However, he didn't understand this script after returning to his normal self.[78]
	+ **Computer specialist/Expert computer hacker:** Barry is adept with computers, as he was the only one who could write an algorithm that monitored the electrical manipulations to National City's network which Livewire's powers caused.
	+ **Cooking:** Barry is skilled in cooking, having made fancy meals for himself and Iris.[151][79]
	+ **Expert investigator/Forensics:** As a CSI of the Central City Police Department, Barry is highly skilled in forensics. From a single glance of the crime scene, he can quickly determine much of the events that transpired. Barry can quickly analyze any given data and quickly form accurate theories on the given situation, as seen with the Arrow; Barry correctly determined the Arrow's training background from his green attire and that he has at least one accomplice. Barry was also the first to deduce the true identity of Savitar, managing to put clues together from various things the evil speedster said and did, ultimately concluding that he was in fact a rogue time remnant of himself. Additionally, having learned from Oliver, Barry is able to case environments and predict every inch of them.
	+ **Expert of deception/Manipulator:** Despite Barry's somewhat awkward demeanor, he can be deceiving if need be. When he traveled back in time to find a way to get faster, Barry kept acting like his past self around everyone. Even when he was busted by Eobard, Barry made the latter believe he was able to achieve his goal mission of returning to his own time, when in truth, he had actually been erased from existence.[45] Barry also successfully distracted Remington Meister and Ultraviolet from launching a missile on Central City by pretending to be severely drunk.[152]
	+ **Master engineer:** Barry has very advanced skill in technology, as he was able reconstruct Captain Boomerang's projectiles from its broken pieces and build from memory a variation of the earpieces used against Hartley Rathaway to help himself and Kara Danvers confront the sonic-powered Silver Banshee. Barry was also able to build a carbine prison from which Reverse-Flash couldn't escape. In one possible future, Barry designed Gideon, a very sophisticated artificial intelligence unit with a system so complicated that even Cisco Ramon had no idea of how it works. Barry is very skilled with crafting and building, having spent weeks personally repairing Central City after the damage caused from the singularity by Eobard. He was also able to completely dismantle a speeding car using a box of mechanic tools.
	+ **Master physicist/Chemist/Scientist:** Barry graduated with a double major in physics and chemistry, making him a very knowledgeable scientist. Barry deduced that Oliver Queen was dosed with a blood coagulant and managed to use a small amount of rat poison to thin his blood again. He also created a compressible micro-fabric green domino mask for Oliver to conceal his identity more effectively without affecting his sight and aim. Barry's knowledge on physics possibly ranks among the best on Earth-1 and 2, as he was able to apply a new-found science and figure out how to close the various breaches between worlds.
	+ **Meditation:** Taught to him by Wally, Barry knows how to center himself to better access the energies that house inside his body and make contact with the other **Forces.** This was helpful when Barry used the Positive Forces in tandem to reset the universe.[153][154]
	+ **Speed Force knowledge:** After receiving the speed equation from Eobard, Barry gained great intelligence about the Speed Force and its usage. After regaining his connection to the Speed Force, Barry gained an even greater understanding of its nature, allowing him to heal Jesse Wells. Furthermore, he knows how to nullify another speedster's powers, as Barry did to Eobard for three months, which he may have learned from Zoom's prison. Further tutelage by Jay Garrick of Earth-3 also gave Barry greater knowledge of the lore, history, and legends of the Speed Force. He gained further in-depth understanding of it from Nora's journal filled with Eobard's own expertise.

"*Fighting is physics. It's not about strength. It's not about size. It's about energy and power. Channel your speed the right way and you can totally take this bad boy down.*"
—Cisco Ramon
* **Master hand-to-hand combatant/Martial artist:** In Barry's youth, he was trained how to box with Joe and Iris West. Although he remembers his time training with them, it never stuck since Barry wasn't much of a fighter growing up. This changed when Barry turned 25 and briefly trained with Eddie Thawne, relearning how to box due to the circumstances with Tony Woodward but this time, the training stuck, with boxing becoming his go-to style of combat as the Flash.[151] While never trained extensively in hand-to-hand combat, Barry's powers combined with his intelligence and combat skills made him a formidable opponent. At the same time Barry continued to gradually improve his abilities, as seen by how he went from being completely outmatched by Eobard to eventually able to decisively beat Eobard during the Earth-X invasion when their speed became equally matched. Later, Barry's combat skills improved to such a level that even without his powers, he was able to swiftly take out two A.R.G.U.S. security guards.
	+ **Expert swordsman:** Against Godspeed, Barry proved capable with a sword. While requiring the aid of Eobard to fend off Godspeed, Barry was able to shatter Godspeed's own sword and force him on the defensive.[155] During everyone's grieving process, Barry traveled to Kyoto to learn the disciplines of being a Samurai, as a way to honor Frost's legacy.[156]
* **Expert marksman:** Barry is proven to be adept with guns, though he does not use them if they could kill someone. Barry and Ralph Dibny once used stun guns stolen from Goldface to fight and knock out all of the latter's forces, as well as briefly stun Goldface himself.[157]
* **Singing:** While quite modest about this skill and not always a fan of performing, Barry is an excellent singer. His karaoke performance at a bar attracted the attention of Linda Park.[46] Barry was also able to pass as a lounge singer in Music Meister's reality.[11]
* **Dancing:** Barry is a talented dancer, especially in ballroom and tap, as seen in Music Meister's movie musical reality.[11] He has also shown during Carrie Bates' "whammie" to be a skilled breakdancer.
* **Artistic:** Barry is a proficient sketch artist, able to accurately draw a picture of Vandal Savage's face.[59]

"*I'll never let the pain, the darkness, determine who I am. I will never be you.*"
—Flash to Savitar
* **Indomitable will/High pain tolerance:** Barry is known for his force of will, with H.R. Wells declaring that his real superpower is hope, having an endless reservoir of it.[158] Even when being burdened of being aged rapidly to over a 100 years old, Barry has shown he can push himself beyond his limits when running. This was displayed when Barry resisted killing Savitar, as he dismissed his urges to do so.[10] Mar Novu described Barry's determination as "boundless" and called it one of his greatest qualities. Furthermore, Barry has a history of changing individuals' hearts and minds, which includes convincing his enemies to do the right thing by knowing how to reach them. As noted by Ramsey Rosso, Barry marches towards death without fear, as he derives his strength from his loved ones. During the Anti-Monitor Crisis, Barry was revealed to be the Paragon of Love due to his positive emotion.

### Weaknesses

* **Antimatter:** Just a slight contact with an antimatter wall in the Speed Force when Barry tried to time travel to the day after Crisis could leave him with a lasting scar. Jay Garrick noted that if not for Barry's accelerated healing, a scratch from antimatter would wipe him out of existence.
* **Cold temperatures:** Because speed is produced by a build-up of heat in the target's atoms, Barry is vulnerable to extreme cold temperatures. Under these conditions, Barry's speed will be greatly reduced. Also, direct exposure to such cold will temporarily stunt his healing capacities. However, since learning to regulate his body temperature with a buildup of energy, he has a much higher resilience to cold.
* **Gamma energy:** Gamma energy can have a negative effect on Barry if absorbed into his body. Reacting to his Speed Force energy, each time Barry uses his powers with the gamma energy interfering, it will cause Barry to biologically age by several years.
* **High density:** Barry has a much greater difficulty phasing through targets with greater natural resistance like carbine and force fields.
* **Hyper-metabolism:** While moving at superhuman speeds, Barry burns calories much faster than a normal person. While breaking down food far more efficiently, it requires him to consume large amounts of nutrients. Continued usage of his speed while deprived renders him disoriented and weak before ultimately passing out from low blood glucose. Also, he is unaffected by sedatives as he burns through them too quickly to have any affect. He also cannot experience a buzz as even 500 proof alcohol only intoxicated him for a few seconds. After naturally increasing his connection to the Speed Force, his performance noticeably increased, requiring much less nourishment in-between his meta exploits.
* **Power-dampening tech:** Initially, Barry's powers can be weakened, even neutralized, by specially designed tech that affects his resonance field. Later, after spending six months inside the Speed Force, Barry's massive build-up of Speed Force energy made his powers highly resilient to such tech, as he instantly smashed his way free of a cell in the pipeline. However, certain meta-powers and more advanced tech can still weaken him, as an upgraded B.O.O.T. slowed him down considerably; but not to the point of suppressing his powers. It is very likely that if he had spent more time in the Speed Force, Barry would become completely immune to such tech, even ones that are very advanced. Also, being a Speedster, special kind of anti-speedster weapons can render a speedster stunned and cut off from the Speed Force. However, the effects are only temporary.
* **Time alterations:** While Barry's speed can break through the temporal barrier, it is not without drawbacks. In addition to potentially causing unforeseeable, damaging changes to the timeline; such reckless actions can alert the Time Wraiths. These temporal guardians become instinctively drawn to the careless speedster, driven to capture him and draw the person into the Speed Force. Also, using his powers in a timeline where he didn't actually acquire them will gradually deplete them and make him lose his memories of the timeline where he gained his powers.
