As a child, Barry Allen's life was uprooted forever by the death of his mother. The police arrested his father for the crime, but Barry had seen a strange man with inhuman powers in a yellow suit commit the deed.
The death drove him to find answers, researching cases of paranormal activity and possible superhuman forces at work. He also found answers in science, getting a job as an intern with the Central City PD Crime Scene Unit. However, he was perpetually late.
Hearing about the Starling City vigilante, he looked into the stories about him, keeping a running tally of the colorful criminals he caught. He followed and developed theories as to the man's operations. When a seemingly impossible case cropped up in Starling City, Allen used deferred sick days to travel across country, claiming that this case connected to something happening in Central City and inserting himself into the investigation.
He proved instrumental to solving the case, even meeting the vigilante, learning his secret identity and saving his life with his chemistry knowledge. Parting with the man on cordial terms, he returned to his duties mere seconds before Central City's new particle accelerator backfired, showering the city with dark matter. In the ensuing confusion, Allen was struck by lightning, but survived. Allen was in a coma for 9 months. During the time he was in a coma, he was moved to S.T.A.R. Labs. He awoke from his coma with the power to move at superhuman speeds, and met Cisco Ramon and Caitlin Snow.
He later would later join them in addition to Harrison Wells as part of Team Flash. Later he encounters with numerous meta-humans and villains, such as, Captain Cold, Heat Wave, but, he would encounter The Man in the Yellow Suit who killed his mother
The Man in Yellow
At a later point in time, Barry would find out that his mentor, Harrison Wells, was secretly the Reverse Flash, and the man who had killed his mother. Wells' real name was Eobard Thawne and was from the future. He had traveled back and got stuck in Barry's period of time. Wells engineered the particle accelerator explosion and began mentoring Barry and helping him get faster so Wells could return to his time-period. With the help of the Arrow and Firestorm, Barry was able to defeat Wells.
At one point point in time, Barry and the rest of Team Flash were visited by a speedster from Earth-2, calling himself Jay Garrick. Jay informed the team of a powerful speedster named Zoom who had stolen his powers. Jay began working with Team Flash to stop Zoom, and became something of a new mentor to Barry.
Following the confrontation of a new speedster named Trajectory, Barry and the team realized that Jay Garrick was actually Zoom. After the team discovered new revelations about Zoom's real history as Hunter Zolomon, Barry attempted to lure Zoom into a trap, but this backfired when Zoom escaped and captured Wally West, forcing Barry to surrender his speed. With the help of his team, Barry recreated the conditions of the night he was given his speed, and regained his powers.
Barry's father is later kidnapped by Zoom and killed in front of Barry. Shortly after, the team tried to take down Zoom on their own, resulting in the abduction of Joe West. Realizing he has no choice, Barry agrees to a race arranged by Zoom, who is planning on destroying the Multiverse, leaving only Earth-1 behind. Barry races Zoom, creating Time Remnants to help him. Zoom is finally defeated and is taken away by Time Wraiths and into the Speed Force.
Sometime after, Team Flash returned to Earth-2 and rescued the man Zoom had been keeping captive, and it is revealed that the man was the actual Jay Garrick and Barry's father's Earth-3 doppelganger.
Barry, emotionally distraught after his father's death, time-traveled back to the night his mother was killed to save her, drastically changing the timeline.
After defeating the Reverse-Flash and returning back to his time, Barry realized he had drastically changed the timeline. Both his parents were alive and Wally West was the Flash. Realizing his mistake, Barry allowed Reverse-Flash to go back in time to kill his mother and reset the timeline, causing a third timeline to set in.
Arrival of Savitar
Returning back to present day after undoing his mistake, Barry discovered that things had still changed, such as his friendship with Cisco, the relationship between Iris and Joe and a new begrudged colleague at C.C.P.D.. Adjusting to these changes, Barry started investigating "husks" whilst trying to secretly help fix the lives of his friends. During this time, an enigmatic figure known as Alchemy began enlightening those from Flashpoint with their alternate timeline memories and powers, such as the Rival. Discovering that Alchemy worked for a self-proclaimed "speed god" called Savitar, Barry and his team began trying to find a way to stop Savitar from breaking out of his prison. Barry later admitted the truth about his manipulation of the timeline to the team, upsetting them and effectively placing his friendship with Cisco in jeopardy. During this time, Barry learned that Wally obtained his Flashpoint self's speed thanks to Alchemy and attempted to dissuade him from following in his footsteps for Joe's sake.
Barry responded to an alert from an incoming object and realized it was an alien ship, reporting back that aliens had landed on Earth. A.R.G.U.S. later responded, with Lyla Michaels confiding the truth to Barry and the others about the existence of a species called "Dominators" and how they've been abducting people since the 1960s. Aware of the worldwide danger this signified, Barry called upon Green Arrow and his team, Supergirl (of Earth-38) and the Legends to stop the Dominators from invading. Whilst preparing for a counterattack, Barry was informed by Martin Stein and Jefferson Jackson about a voice message from his future self, telling them to trust no one, not even himself. Attributing this to his creation of Flashpoint, Barry told them the meaning of the message and was forced to later tell the truth to the others, realizing that not only had he effected his team's lives but also that of John Diggle (whose daughter was erased and replaced with a son). With the makeshift group's trust in Barry broken, they went without him to investigate the origins of the Dominators and to stop the invasion from occurring. Oliver and Barry stayed behind and were the ones forced to battle their friends when the Dominators mind-controlled them. Barry, realizing that the mind-controlled Supergirl could help destroy the device, taunted and tricked her into doing so, undoing the effects. The group of heroes eventually regained their trust in Barry and were able to work together once more. However, Oliver and many non-powered individuals close to him were abducted by the Dominators and placed into a reality where none of them became vigilantes. Barry and some of the remaining heroes left to find a way to hack into the Dominator's technology. After doing so, Barry was told that the reason why the Dominators attacked Earth was due to his actions in making Flashpoint, representing the threat of meta-humans being able to do unimaginable things with their abilities. Barry chose to take responsibility for his actions and willingly gave himself up, to which his allies convinced him not to. With a way to disrupt the Dominators across the world, Barry races across the planet placing the devices on as many as possible in order for Felicity to enact the plan. Despite being successful, the Dominators used a meta-bomb as a last-ditch effort in eliminating meta-humans. Barry witnessed Firestorm transmute the bomb into water, negating the effects and forcing the Dominators to flee.
Barry, still facing the threat of Savitar and Alchemy, enlisted Jay Garrick of Earth-3 for help. Uncovering the true identity of Alchemy, being his colleague Julian Albert, Barry tried to persuade him to be a middleman between him and Savitar in order to glean information out of him. Being told of a prophecy that including one of them dying and another betraying the team, Barry ultimately decided to throw the Philosopher's Stone connected to Savitar into the Speed Force, having the adverse effect of throwing Barry into the near-future. Witnessing his future self failing to save Iris, who was brutally killed by Savitar, Barry returned to present day and obsessed over preventing that future from coming to pass. Barry kept the truth secret but eventually told the team sans Iris herself. Drawing up a list of events that occur leading up to her death, Barry obsessed over changing the outcome of every event, such as having Wally, now Kid Flash, stopping Plunder instead. After a run-in with a bounty hunter from Earth-19, called Gypsy, Barry and the team were able to save the new Harrison Wells, H.R., from facing execution for traveling between universes. Barry later concluded that it should be Wally to save Iris instead and began training him to increase his speed.
When Jesse Wells returned from Earth-2 with news of her father's abduction at the hands of Grodd, Barry, Cisco, Caitlin and Julian all traveled to her Earth to rescue him. However, they were captured and awoke in Gorilla City, where Grodd asked Barry to defeat their leader, Solovar to prevent an imminent attack on Central City. After heeding to his request, Barry discovered that Grodd lied and only wished to usurp Solovar to attack the city himself. Conjuring a plan to trick Grodd and escape, Barry had Caitlin fake his death with her newly attained cold-powers and, taking Harry with them, escaped back to Earth-1. Unbeknown to them however, Grodd had captured Gypsy and secured a means of traveling to Earth-1 to fulfil his plan. Barry and the team were forced to battle Grodd and his army in the streets whilst Cisco and Gypsy went to find Solovar to prove Grodd's betrayal. Having defeated Grodd's forces and exposed Grodd's plan to Solovar, Barry considered killing him once and for all but wisely left Grodd in Solovar's hands, ending the threat.
Return of Savitar
Despite having presumably destroyed the Philosopher's Stone and kept Savitar trapped, Wally and Barry found themselves haunted by the villainous speedster. Wally informed Barry that Savitar has been affecting his mind, making Barry angry for keeping such a thing a secret. Warped by his protectiveness over Iris, Barry was convinced that Wally was being controlled like Julian and fired him from the team. Fearful that Savitar's possible return might once again place Iris in danger, Barry asked Cisco to act as another middleman in order to talk to Savitar. After being teased with the possibility that the Philosopher's Stone may not be totally destroyed, Barry learned that Caitlin had kept a piece of it hidden in the hopes of getting rid of her powers.
- Speed Force Conduit: After being hit by the dark matter lightning from the particle accelerator explosion and exposed to various chemicals, Barry's DNA was altered and his cells were supercharged with enormous amounts of electricity, augmenting his physiology, and granting him access to the extradimensional energy source called the Speed Force.
- Superhuman Speed: Barry is able to move at vast superhuman speeds. He is also unaffected by the side-effects of moving at these speeds such as high friction, air pressure, reduced oxygen, and kinetic impact. The intensity of his speed allows him to run across vertical structures and over large masses of water. While able to reach Mach 3.3 on his own and later augmenting his speed by using a tachyon device to reach Mach 13, Barry has since gained a stronger connection to the Speed Force, making him considerably faster.
- Superhuman Reflexes: Because of his great speed, Barry's reflexes are heightened to superhuman levels, allowing him to react to danger instantly. His reflexes are great enough to allow him to catch a bullet while standing still.
- Superhuman Agility: Barry's balance and bodily coordination are far superior to the finest human athlete. He is able to make sharp turns on streets without losing balance, and leap far and high in the air, while running.
- Superhuman Stamina: Barry possesses superhuman stamina, which allows him handle the stress of running at superhuman speed, without getting tired or weak.
- Superhuman Durability: Barry possesses far greater durability than a normal human, due to his body being adapted to the effects of moving at super-speed. He is able to withstand hits from superhumanly strong meta-humans, and only be momentarily stunned.
- Accelerated Healing: Barry is capable of healing at a rate much quicker and efficiently than regular humans. When he severely fractured his arm shortly after gaining his powers, the break healed in three hours.
- Aerokinesis: Barry can use his speed to generate air flow as vacuums on various levels. He can suffocate people by creating a vortex around them by running around them. He can spin his arms to create tornado to remove air from fire and extinguish it and repel targets away.
- Dimensional Travel: With a tachyon device, Barry is capable of moving fast enough to break open portals to alternate dimensions, although he has only done this once by accident, and needed assistance to return back to his earth.
- Electrokinesis: Barry's body generates an aura of Speed Force lightning when he is moving at super speed. By generating enough friction on a specific part of his body, such as his hands, he is able to produce a strong shock, capable of reviving someone. Barry is also capable of electrifying water by rapidly running on it.
- Electro-Blast: After being trained by Jay Garrick, Barry learned to build up and redirect the electricity his body produces, and hurl bolts of lightning.
- Energy Absorption: Barry is able to drain electrical energy from outside sources.
- Healing: Through physical contact of his electrical Speed Force energy, Barry was able to heal Jesse Wells from a coma.
- Enhanced Mental Process: Barry's brain is able to process information at a highly accelerated rate, which allows him to perceive time and events in slow motion, as well as take in and process large amounts of information.
- Enhanced Senses: Barry's speed extends to his senses, allowing him to see and hear normally when moving at increased speed, even when moving at, or above the speed of sound, where this would normally be impossible. The Speed Force also grants Barry extra temporal senses.
- Molecular Acceleration: Barry can vibrate his molecular structure at various levels to achieve various effects. He can accelerate the molecules in his throat to distort his vocal cords to disguise his voice.
- Intangibility: Barry can vibrate his cells, making his body intangible. He frequently uses this power to vibrate his entire body to conceal his identity from others.
- Phasing: By vibrating his molecules at the frequency of the air, Barry is capable of phasing through solid objects.
- Speed Mirages: Barry can use his speed to make it appear as if he's 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, allowing him to disorientate his enemies.
- Speed Lending: Barry can temporarily extend his Speed Force to others, allowing them to move at super-speed for a short time.
- Speed Steal: By trailing another speedster, Barry is capable of siphoning off speed from them to bolster his own speed.
- Time Deceleration: When Barry and Supergirl ran around the Earth in opposite directions at just over Mach 7, they were able to generate enough centrifugal force to slow the Earth's rotation, along with time itself.
- Time Travel: Barry can move fast enough to break open holes in the fabric of time and space, allowing him to travel through time. This power was formerly uncontrollable, as the first two of his time travels were achieved by accident, although Barry has since then gained partial control over this power.
- Reality Alteration: By preventing past events from happening, while time-traveling, Barry can unintentionally alter the present reality. This was displayed when Barry traveled back in time and saved his mother from being killed, and accidentally altered the entire universe, creating the Flashpoint timeline.
- Time Remnant Creation: Barry is able to essentially "clone" himself by creating a time remnant, a version of himself from either his past or future. He can do this by time traveling back moments before his current self time travels, producing a time remnant as a result, hailing from a future that no longer exists. This effectively allows for Barry to be two places at once.
- Computer Operation
- Cooking: He has decent cooking skills- It is demonstrated when he prepared omelettes for himself.
- Forensic Pathology
- Indomitable Will
- Hand-to-Hand Combat (Advanced): Held his own for a while against Griffin Grey without powers. Even without his superspeed, Barry was able to swiftly take out two A.R.G.U.S. security guards simultaneously. Upon fighting Cicada for the fourth time, Barry stood up to him for a considerable period of time even when Cicada used his dagger, landing multiple hits on him without the use of his powers. Only losing due to the Cicada's superhuman strength and durability. Later, Barry's combat skills improved to such a level, that he fought on par against Ultraviolet for while without using his powers and ultimately bested his opponent by dropping stage lights on her.
- Boxing: Trained how to box with Joe West, Iris West and Eddie Thawne; Barry even practices boxing in his free time.
- Hyper-Metabolism: While moving at accelerated 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.
