Aside from a few occasional ShipTease moments, they never show any intention of wanting to get together.

After being struck by lightning, he falls into a coma and awakens as a "[[DifferentlyPoweredIndividual metahuman]]" with SuperSpeed, which he eagerly uses to fight crime, find other meta-humans, and eventually find his mother's killer.

* NowOrNeverKiss: Knowing that what he is about to do, ''(actually stop Thawne from killing his Mom)'', the entire time line will change, and the next time he sees her, things will be radically different between the two, he seizes the opportunity to finally share a real kiss with Iris, and let her know how much he loves her one last time, before he leaves.

leaves. Later shares this with ''Flashpoint'' Iris, knowing that allowing Eobard to ''fix'' the timeline will result in her being RetGone'd, he shares one with her before leaving Flashpoint behind.



* OOCIsSeriousBusiness: To characterize how much despair Henry's death has caused him and how much he has come to hate Hunter Zolomon, Barry outright admits to Joe that he doesn't want to just kill Zoom -- he wants to make him ''suffer''. Considering that Barry is usually merciful and only resorts to killing as a last resort, this was enough to alarm the rest of the team into locking him up in the Pipeline until Barry calmed down.* OpenSecret: His SecretIdentity borders on this as the series goes on. One character (who runs a company that competes with Star Labs) casually reveals that she knows Barry is TheFlash, and when he asks how the response is "I'm not stupid". It doesn't help that Barry is pretty casual about revealing his identity to people anyway, often for reasons as trivial as boosting their morale.

* SherlockScan: Particularly evident in the early episodes, especially the pilot before he became the Flash. As Barry looks over the crime scene, the clues he spot are accompanied by visual text to show Barry's observations (much like how the TropeNamer [[Series/{{Sherlock}} does so]]). He was able to discern exactly what type of car the Mardon brothers used in their getaway from a robbery from analyzing a tire track, and figure out a vague location from a piece of excrement mixed with the track; all within a minute and without the use of any equipment.* ShipperOnDeck:

Cue a lightning strike and Barry looking out at it for a few seconds.

->'''Known Aliases:''' Franchise/TheFlash, The "Red Streak", The Fastest Man Alive, The Scarlet Speedster, The Man Who Saved Central City, [[Series/{{Supergirl 2015}} The "Blur"]], "Bart"
->'''Played By:''' Creator/GrantGustin, Logan Williams (young, Seasons 1-2), Liam Hughes (young, Seasons 3-)
->'''Voiced By:''' Arturo Castañeda (Latin-American Spanish dub), Creator/JunFukuyama (Japanese dub)

->''"To understand what I'm about to tell you, you need to do something first: you need to believe the impossible."''

An assistant crime scene investigator in Central City with a habit of being late. After the murder of his mother by a "man in yellow", he develops an interest (some say obsession) in "impossible" crimes and events. He first appears in-universe in the mid-season 2 two-parter in ''Series/{{Arrow}}'' investigating a break-in by a thief who apparently has SuperStrength. After being struck by lightning, he falls into a coma and awakens as a "[[DifferentlyPoweredIndividual metahuman]]" with SuperSpeed, which he eagerly uses to fight crime, find other meta-humans, and eventually find his mother's killer.
----
* TenMinuteRetirement: Very briefly quit being the Flash due to getting his ass kicked in his first fight with Multiplex ''and'' Joe chewing him out. Fortunately, he gets his motivation back quickly.
* HundredPercentHeroismRating: As of "The Man Who Saved Central City", evidenced by the massive cheering crowd that assembles at the rally in his honor.
* AuthorityInNameOnly: Him being the owner of S.T.A.R. Labs has yet to affect the plot in any way.
* AdaptationDyeJob: Barry Allen has light blond hair in the comics, but dark brown hair on the show.
* AdaptationalCurves: Inverted. In the comics, Barry has a straight-out HeroicBuild. [[note]]But not to the level of Creator/JohnWesleyShipp's [[Series/TheFlash1990 version]][[/note]]. Here, he more or less has a "HollywoodNerd GeekPhysique".
* AdaptationPersonalityChange: This Barry Allen is a lot more nerdier and geeky than he's usually depicted as.
* AdaptationalWimp:
** In this version, despite his power, he seems totally unable to beat an opponent without the support of his team (the majority of the time). Justified since not only is Barry still relatively inexperienced, he has a bad habit of rushing in without thinking as well as over relying on his SuperSpeed (something Oliver chastises him about InUniverse), otherwise he'd function as a StoryBreakerPower.
** This is somewhat rectified in Season Two, where he's fighting more battles and stopping more criminals while being guided through step by step less often, along with learning and using even the more difficult new powers like throw lightning and making Speed Mirages more effectively and in a short amount of time, along with honing his known moves thanks to about a year of experience. Hell, he's starting to take Oliver's advice about using precision, analyzing the situation and his surroundings to his advantage more to heart, as seen with Dr. Light and even Zoom. A true testament is his victory over the Reverse-Flash and Zoom, using both his speed and brains without any outside help.
* {{Adorkable}}: Portrayed this way ever since his first appearances on ''{{Series/Arrow}}'', having a tendency to get himself tangled up in his social life and tripping over his own words.
** During their double date, Iris even notes Barry is just like Felicity - a member of the rare breed of "adorable nerds".
* AesopAmnesia:
** A big part of Barry's CharacterDevelopment in Season Two is learning to accept Nora's death and being a hero doesn't make him immune to tragedy. Unfortunately, Zoom killing Henry (the second parent to be killed by an evil speedster) coupled with the real Jay Garrick being the doppelgänger of his father pushes Barry over the edge and he decides to abuse his time travel abilities to save Nora, consequences for the world be damned. Though from the looks of things at the start of Season 3, this will most likely be subverted.
** In Season 3, [[spoiler: he accidentally goes into the future and sees Savitar killing Iris, but Jay is able to convince him that this is only a ''possible'' future and that he should just ignore it lest he accidentally creates a StableTimeLoop. However Barry begins having night terrors about it and when he realizes that the events leading to Iris' demise are about to happen he and Team Flash try to avert them - to no avail.]]
* AgeLift: A bit younger than Barry's usual depictions, which is actually turned into a plot point when it's revealed that the "Man in Yellow" turned him into the Flash seven years early (giving Barry his powers in 2013 instead of 2020).
* AgentMulder: Perfectly willing to accept that one guy with SuperStrength was behind the break-in at the Queen Consolidated warehouse, and actively seeks out weird cases.
* AllLoveIsUnrequited: Downplayed. Felicity Smoak is genuinely fond of him, but he's more interested in Iris West.
* AllLovingHero: Barry sees the best in everybody, while refusing to blur the line between black and white. In "Tricksters", Joe tells him that this specifically is his most valuable asset, more than his physical superpowers.
** Taken UpToEleven in ''Rogue Air'' when Thawne reactivates the Particle Accelerator and Barry tries to move the meta-humans to another location, since he refuses to let any of them die even though most of them tried to kill him.
** Despite their past animosity, Barry even sees some good in Captain Cold of all people. And the events of "Family of Rogues" prove Barry right.
*** He is genuinely saddened in "Invasion" [[spoiler: when he is told of Snart's HeroicSacrifice.]]
* AllOfTheOtherReindeer: Henry wanted him to change his surname so people would stop giving him grief about being related to a (albeit innocent) murderer.* ArcSymbol: Different kinds of prisons are heavily associated with him, signifying how he can't move on from the fateful night his mother was murdered no matter how much he tries.
* ArmourIsUseless: Subverted, his suit was originally protective gear for firefighters. It doesn't work well in protecting against physical attacks such as Green Arrow's throwing knife or Zoom's claw to the gut, but it helps a bit against Captain Cold and company's weapons. It also completely protects Barry against the hand blasters that S.T.A.R gave Linda, when they disguised her as Dr Light.
* ArchEnemy: Poor Barry seems to pick up at least one new ArchEnemy OnceASeason.
** Season 1: The Reverse-Flash, aka Eobard Thawne, who murdered his mom, framed his dad for it, and then manipulated Barry's life all while the under the guise of TeamDad Dr. Wells. He is Barry's most personal enemy, but not necessarily his most hated one. Make no mistake, though, they do hate each other -- a ''lot''; their destinies are so intertwined that they will never be fully rid of one another -- they both tried and realized it wasn't possible, something that only makes them hate each other even more. [[spoiler:When Barry needs Thawne to help reset the timeline by murdering his mother (again), Thawne decides to twist the knife a little bit further by demanding that Barry tell him ''exactly'' what he needs him to do]].
-->'''Barry''': I hate you.
-->'''Eobard''': And I hate you. And I sometimes wonder which of us is right.
** Season 2: Zoom, aka Hunter Zolomon, who pulled the same trick as Thawne did by impersonating Jay Garrick and presenting himself as an ally all so he could steal Barry's speed to cure himself. Zoom would then beat the crap out of Barry several times, with their first confrontation ending with Zoom breaking his back and humiliating him in front of all of Central City. Combined with kidnapping Caitlin and Jesse, holding the latter hostage to force Harry to do his bidding, and holding the real Jay Garrick in a carbine cell as a trophy (with plans to do the same with Barry), topped off with him murdering Barry's father right in front of him, ''in the very same spot where the Reverse-Flash murdered his mother no less'', Zoom is the top contender for Barry's worst enemy by far -- he inspired a deep hatred in Barry that not even Thawne was capable of.
** Season 3: Savitar, who believes he is Barry's worst enemy. [[spoiler:He traps Wally into the Speed Force and, in the future, kills Iris. Then it's revealed that Savitar is actually Future Barry, post-FaceHeelTurn, who is trying to ensure a StableTimeLoop by killing Iris so Present Barry becomes him. That means Barry is HisOwnWorstEnemy -- ''literally'']].
** Captain Cold was this, before he and Barry became FriendlyEnemies. [[spoiler:The Speed Force even outright states that Snart's Heroic Sacrifice at the end of ''Legends of Tomorrow'' Season One was inspired by Barry and his belief that there was good in Snart]].
** Grodd has taken Cold's place as Barry's top non-Speedster enemy. By the time "Attack on Gorilla City" happens, Grodd has forgone all former attachments and his sole concern is getting revenge on Barry for exiling him to Earth-2 by any means necessary.* AscendedFanboy: Barry idolized superheroes like the Arrow, and was thoroughly delighted to meet the Arrow and his secret identity in person. A season later, he himself becomes a superhero.
* AtrociousAlias: His own thoughts on his first alias, "the Streak", as he explains in "Fast Enough". When he visits Series/{{Supergirl|2015}}'s Earth, he is not overly enthused when Cat Grant dubs him "[[Series/{{Smallville}} the Blur]]". When he "suggests" the Flash, Cat points out a certain other meaning of that word. His reaction makes it clear he'd never thought of that before. Oh, before we forget, Cat [[InSpiteOfANail also suggested "The Streak"]] before settling with "The Blur".
* AwesomenessByAnalysis: Displays this ability in the pilot, knowing a car's exact make and model based off of faint tire tracks left at a crime scene.
* BadassAdorable: Barry is nerdy, lovable and incredibly endearing but DO NOT underestimate him as he can kick ass like no other.
* BadassBookworm: Police forensic scientist gets superpowers and fights crime.
* BadLiar: Joe and Iris seem to think so.
* BeautyIsNeverTarnished: His face doesn't typically suffer anything severe, save for a few nicks and dings. Justified, as he heals at a much faster rate than your regular human.
* BecauseDestinySaysSo: Oliver thinks that the lighting bolt that struck Barry wasn't random:
--> '''Oliver:''' I don't think that bolt of lighting struck you, Barry; I think it ''chose'' you.
* BeingGoodSucks: Best exemplified in Season Two, where Barry manages to imprison a time traveling Eobard Thawne (a time remnant), in the Pipeline before he killed Nora or the the real Dr. Wells in his timeline. Unfortunately this causes time paradoxes so Barry has to let him go.
* BewareTheNiceOnes: Barry is generally a nice, sweet guy but if you cross him or hurt anyone that he cares about, he won't hesitate to kick your ass.
* BigBrotherInstinct: Towards Wally, though he is only his foster brother, and the two didn't grow up together like he did with Iris, Barry is incredibly protective of him.
* BigDamnHeroes: Starting to rival Oliver in these moments. Notably, he gets a pretty spectacular one each season during the crossover with ''Series/{{Arrow}}'' where Barry will come in and save Oliver and Team Arrow from a main villain.* BigDamnKiss: Finally kisses Iris before going to save Central City from a tsunami, but when he accidentally travels back in time this is erased.
** Later shares one with her on the West's front porch after defeating Zoom, even with the two's silhouettes being [[LipLockSunBlock eclipsed by a background light]], [[spoiler: yet this too is erased, due to Flashpoint.]]
** And shares yet another LipLockSunBlock variety when the two officially cement their status as a couple.
* BigEater: It turns out that his SuperSpeed speeds up his metabolism too, [[BlessedWithSuck and if he doesn't eat heavily, he collapses from hypoglycemia.]] He also can't get buzzed by alcohol unless he drinks ultra-high concentrated alcohol, and even then, it only lasts briefly.
* BigGood: A role he shares with Oliver Queen. They're both the first public superheroes in the Arrowverse, and set examples for many heroes after them, while leading their respective teams. They are the two vital heroes of the Arrowverse, and without them, all hell would break loose.
* BirdsOfAFeather: With Felicity Smoak. They're both {{Adorkable}}, super-excitable nerds who are ''awful'' at saying what they actually mean. He's also this with Patty Spivot for many of the same reason. And later with Kara Danvers, as they're both {{Adorkable}}, super-excitable superheroes who absolutely love saving people and having adventures.
* BlessedWithSuck: His speed power is a fantastic thing, except for one hitch. His metabolism is so high that even a heavy dosage of anaesthesia has no effect on him, when he has to go in for surgery (including removing hundreds of barbed needles out of his body) he's going to feel all of the pain for the whole time. Also, depending on whether or not he can shift his perception from normal to BulletTime at will, [[FridgeHorror the procedure would feel like it's taking years.]]
* BorrowedCatchphrase: In season 3, he has sometimes used Oliver's CatchPhrase "Suit up!"
* BoyNextDoor: He is considerate and selfless. In the case of Iris, ''literally'' next door, as he lived with her growing up.
* BreakoutCharacter: He is the most popular hero of the [[Series/{{Arrowverse}} Arrowverse]] (in ''and'' out of universe) and is essentially its SeriesMascot.
* BreakTheCutie: While still trying to deal with everything that the Reverse Flash put him and those he's close to through during Season 1 and contending with all the crisis that Zoom and the Earth 2 Meta's are throwing at him currently, and that's without even touching upon the issues in his civilian life, makes Season 2 an immensely long one for him, culminating in his DespairEventHorizon at the end of the season.* BrokeYourArmPunchingOutCthulhu:
** While not to Cthulhu levels, Barry breaks his hand punching [[ChromeChampion Girder]] in the face.
** The first time he fought Zoom he ended up with his back broken.
** Whenever Barry engages Savitar, he's always on the receiving end of a CurbStompBattle, with Savitar dragging him around the city and pummeling him or punching him around the room with ease.
* BrokenHero: By Season Three as the consequences of Flashpoint continue to take their toll not even counting all of his past failures which still haunt him.
* BrokenPedestal:
** Barry idolized the Arrow but upon actually meeting him he is seriously off put by how much of a jerk Oliver can be. Similar things happen in subsequent crossovers with Barry's initial enthusiasm getting derailed by Oliver's more brutal methods. Ultimately subverted when Barry learns to see Oliver / The Arrow as an ally with his own strengths and flaws rather than an idol.
** The Flash becomes a Broken Pedestal to Iris when he brutally attacks Eddie while under a HatePlague. However she quickly changes her mind after he saves Eddie from Cold and Heatwave.
** As of "Rogue Time", "Wells" seems to have finally become this to Barry; Barry knew Mason Bridge was investigating, claiming to know some very dirty secrets about him and that he'd reveal it all soon -- and then Bridge [[RevealingCoverUp mysteriously disappears. Barry doesn't think it's a coincidence and finally starts to grow suspicious of "Wells".]]
** The events of "Flashpoint" made Barry this to the other superheroes — specifically Cisco (who lost his brother), Diggle (whose daughter was changed to a son) and the Legends (who now have a new threat to deal with [[spoiler:including one of their own partners]]) — since he was always held up to a higher standard by being the most virtuous of them all. However his willingness to sacrifice himself to the Dominators if it meant they would leave Earth rebuilt that pedestal.
* BroughtDownToBadass: The penultimate episode of Season Three shows that even without his powers, Barry has become a skilled hand-to-hand combatant, able to take out two highly-trained guards with relative ease. While not quite on the level of the members of Team Arrow, with or without his speed, Barry is nowhere near helpless.
* BroughtDownToNormal:
** Temporarily during ''Power Outage'' when Blackout drains the electricity from his body and depowers him. Fortunately Barry is able to recover from it [[TookALevelInBadass and becomes even faster then before]].
** Happens again in ''Verses Zoom'' when the titular Zoom forces Barry to siphon off his speed and give it to him or risk having his friends and family murdered. Barry reluctantly agrees and has the speed force drained from his body.* BulletCatch: Barry is eventually fast enough to catch bullets, the first time he did so it was fired at his neck from behind and ended up grazing him.
* BullyHunter: He's aggressively anti-bully, especially since he had to deal with them a lot as a kid. Best shown in "The Flash Is Born" when he goes after one of his childhood bullies and now metallic metahuman, Tony Woodward.
* ButtMonkey: In the first episode alone he gets battered by a mugger, struck by lightning & goes into a coma for 9 months, all in the space of an evening, then wakes up to find that the woman he's in love with has begun a relationship with another man during said coma. [[ThrowTheDogABone But hey]], he gets SuperSpeed.
* CameBackStrong: Of the non-death version. After Barry had his powers stolen by zoom, he later enters the speed force and while inside learns to harness it's power effectively. The trip itself not only restores his connection to the speed force but increases it drastically as before Zoom was about four times faster than him and after he came back he was faster than Zoom [[UpToEleven who has his power plus what he stole from barry before]].
* CantKillYouStillNeedYou: It drives Eobard crazy that he needs Barry's speed to get back home and that he can't kill him like he ''really'' wants to.
* TheCape: Barry is basically the counterpart to Oliver Queen's TheCowl. The two-part crossover of "Flash vs. Arrow" on ''The Flash'' and "The Brave and the Bold" on ''Arrow'' is an extended look at how Barry's city is clean and a nice place to be and had to be bombarded with metahumans before it needed a hero, one like Barry, who's sweet and kind, contrasting them with Oliver and his city. Once he's revealed to the public, he fully embraces being a symbol of hope for Central City. The one time he ''tries'' to be TheCowl it backfires in his face spectacularly.
* CassandraTruth: The only people who truly believed Barry's story about his mother's murder were... Barry & his father, who were the only people to witness it. Many flashbacks show a tearful ten year old Barry trying to convince people to let his dad go. Present-day Barry is still very bitter over this.
* CharacterDevelopment: Barry has become more confident, forceful and driven than he was during his first appearance on Arrow; stammering a lot less and interacting with more ease, which he might owe to his powers. According to the creators, it won't stop there...
--> '''Andy Kreisberg''': It's Barry Allen coming to terms both physically and emotionally with what's happened to him. He's not really The Flash yet because he's still in the early days. By the end of the year, he will come to resemble The Flash that we know from the comic books. That's really the arc for the first year.
** WordOfGod say that Season three will see Barry take another big step in his maturity, particularity when it comes to the facing the consequences of his actions, creating Flashpoint especially when it comes to his powers, and learning to move on and being stronger for it.
--> '''Andy Kreisberg''':“He really becomes an adult and that’s been really exciting for Grant, that’s been really exciting for us — it was very black and white before this, very ‘that’s good and that’s evil,’ and like most adults, Barry has to learn that people make mistakes. The question isn’t ‘Did you make a mistake or not,’ it’s ‘What are you gonna do about it?’ And if there’s nothing you can do about it, how are you gonna live with yourself?” * ChickMagnet: He's been involved, or at least had a ShipTease, with ''four'' women in the first season alone, namely; Iris, Felicity, Caitlin and Linda.
* ChildhoodFriendRomance: With Iris West -- Barry had loved Iris before he even knew what love meant, and explicitly admits he had a crush on her even before his mother died. It takes some time, but they finally start dating at the start of Season 3.
* TheChosenOne: In [[Series/{{Arrow}} Oliver Queen]]'s own words, the force behind the lightning that struck Barry chose him for a reason. Additionally, Eobard Thawne keeps implying that there is something special about his speed. "The Runaway Dinosaur" confirms this by having the Speed Force itself state that it specifically chose Barry.
* ChronicHeroSyndrome: He's compelled to save people. This gets deconstructed in Season 3 when [[spoiler: he sees a future in which Iris will die and is desire to save her causes sever lapses in his judgement.]]
* ClarkKenting: Cleverly averted, as most of the people who get a clear look at him in action already know about him. When he has to appear in front of people not in the know who might recognize him, he vibrates his face so it becomes a blur, and also his vocal chords.
* ClearTheirName: Knows his father is innocent and won't rest until everyone else knows it too.
* {{Cloudcuckoolander}}: Has a vested interest in weird crimes which can't be explained with pure fact and logic, due to his mother's death being such a case. Detective West repeatedly tells Barry to stop looking into such cases & accept that his father killed his mother, not a "ball of lightning with a man inside."
* TheCloudcuckoolanderWasRight: Considering Barry himself becomes the fastest man alive and Clyde Mardon can control the weather, Detective West realises that Barry was right about everything upon seeing it for themselves.
* CompositeCharacter: This version of Barry Allen can be very impulsive and reactive much like his grandson Bart, the fourth Flash. He can also be very forgiving to enemies like Snart and sympathize with them just like Wally West. Having Zoom as an {{Archenemy}} is also a trait he shares with comic book Wally.
* TheCoroner: He works for the CSI unit of the CCPD.
* CosmicPlaything:
** Much to his chagrin his life is so intertwined with Eobard Thawne's, that when he attempts to stop Thawne's villainy before it even begins it causes no end of temporal paradox because their two time lines are in reverse. ** It's something of a sick joke that he can't stop evil speedsters from killing his loved ones: Thawne killed Nora when he was 10 (and going back in time to stop him just breaks the universe), Zoom killed Henry right in front of him, but was too slow to stop it, and [[spoiler: Savitar kills Iris with Barry being powerless to rescue her]]. The poor boy's ''cursed''. It's implied that the time with Zoom was because the Speed Force felt a need to put their champion through a SecretTestOfCharacter.
* CreateYourOwnVillain: [[spoiler: By creating and then negating Flashpoint, Barry created a "ripple" that led to creation of the StableTimeLoop that created Savitar.]]
* DeadpanSnarker: Barry can throw in a snide comment when the moment calls for it.
* DespairEventHorizon: He hits it at the end of Season 2 - not only does he lose his father, but when the real Jay Garrick turns out to be his dad's double you can practically ''see'' Barry die inside. At that point, he decides he just can't take any more punishment and goes back in time to save his mother, setting the Flashpoint story in motion.
* DeusExMachina: His TimeTravel ability, which is why it's used sparingly.
* {{Determinator}}: He'll flip cars to catch local Central City bad guys.
* DimensionalTraveler: DependingOnTheWriter, his SuperSpeed allows him to cross TheMultiverse at will.
* DitzyGenius: He's has a keen mind and is undeniably brilliant in the field of science, but he has a severe lack of common sense out the battle field, having a tendency to charge into battle blindly and get his ass kicked. He's also had quite a few IdiotBall moments, such as recruiting Snart to help in a metahuman prison transfer. [[RealityEnsues It doesn't work out]].
* DorkKnight: He's a bit awkward and is prone to geek-outs, but he's brave and has a big heart.
* TheDreaded: The Flash is this to many metahumans. Wells reveals a list of the metahumans on his world, and there are hundreds if not thousands. Earth 1 should have far more because the Earth 2 particle accelerator explosion was contained unlike Earth 1's. However, the vast majority of the metahumans are in hiding out of fear of the Flash.
** Also, even to Zoom at some extend, giving his BigNo upon seeing Barry attempting to regain his powers and his rush off to try stop him.
* DudeWheresMyRespect: Not as the Flash, but in his day job most of the CCPD (sans Joe and Eddie) seems to take him and his forensic work for granted.
** Get's even worst, [[spoiler: with his RetCon of the timeline]] by the addition of [[JerkAss Julian Albert]], his professional nemesis and superior!
* DudeWheresMyReward: The Flash has saved countless people and all he has to show for it are two murdered parents and [[spoiler: one murdered fiancee]]. Iris actually has to remind that the Universe doesn't keep score.
* EarlyBirdCameo: Had a two episode guest appearance on ''Series/{{Arrow}}'' before headlining his own show.* EarlyInstallmentWeirdness: In the "Pilot", when Barry first gained his speed, he didn't have any lightning trailing behind him as he ran. This continues until he first dons the Flash suit and faces off against Clyde Mardon.
* TheEveryman: Of a sort. Barry is a lot geekier than the average Everyman character, but that fits with the show's target audience of comic book/sci-fi fans.
* EveryoneCanSeeIt: Over the course of Season One, many characters who have seen him and Iris together can tell that Barry is in love with Iris. For the first nine episodes, only one person was oblivious to his affections. Unfortunately for Barry, that person was Iris herself.
* ExperiencedProtagonist: By Season 2 of his own series, since he has a year and a half of experience as a superhero, enough to mentor [[Series/{{Supergirl 2015}} Kara]] and give her advice when they first met, then Wally in the Flashpoint timeline, and Jesse.
* FailureHero:
** The first season is tough on Barry in this regard. By the end of it Captain Cold has released all the Metahumans that Team Flash had captured, Barry is unable to defeat Reverse Flash on his own and stop the singularity resulting in Eddie and Ronnie respectively having to perform {{Heroic Sacrifice}}s. This all takes a toll on Barry by the start of the second season.
** Gets even ''worse'' in Season 2, with Zoom kicking his ass throughout the Season, getting Earth-2 Joe killed, being tricked by "Jay", having his speed stolen by Zoom, him being unable to do anything when Zoom kidnaps Caitlin and kills a bunch of cops, and Zoom killing his father right in front of him.
* FatalFlaw:
** His ChronicHeroSyndrome when combined with his time travel abilities makes for a very bad combination. It's repeatedly stressed that he could really screw up the timeline if he wanted to, as the Season 2 finale demonstrated.
** He can also be a little too easy to emotionally provoke, especially when it comes to his loved ones being threatened, to the point that he ignores the potential consequences of his actions.
** Barry is really bad at dealing with personal loss, although this is somewhat understandable given the frequency his loved ones are killed ''right in front of him''.
* {{Foreshadowing}}: When he messes about with the chemicals in the lab, making comments about how it's dangerous to have them so close together, Felicity responds that maybe he shouldn't be touching them. Cue a lightning strike and Barry looking out at it for a few seconds. This is a nod to the most well-known of Barry's origin stories: getting doused in chemicals after a lightning bolt knocks him into it. At the end of "Three Ghosts" in ''Arrow'', this is indeed how Barry gets his powers, with the lightning bolt being generated by Star Labs' overloaded particle accelerator. * FirstLove: It can be argued that he is both this ''and'' SecondLove to Iris; while Iris entered a relationship with Eddie Thawne first and loved him a lot, it's been confirmed that she was in love with Barry long before she had even met Eddie, and simply hadn't realized it yet.
* FishOutOfWater: ZigZagged when he traveled to Series/{{Supergirl|2015}}'s Earth. One one hand, he doesn't need to adjust as much despite being TrappedInAnotherWorld, as both Earth-38 and Earth-1 are set in regular PresentDay [[RetroUniverse unlike Earth-2]]. On the other, none of the people from his Earth have counterparts there.
* FlashStep: No {{pun}} intended. There's a reason why he was nicknamed "the Streak" at first. To normals, whenever Barry uses his speed, all that's seen is a trail of lightning.
* {{Foil}}: Of a sort to Felicity Smoak. Both of them are the {{adorkable}} [[TheHeart heart]] of their teams, with both being quite smart and geeky. However, while Felicity is the sole [[TheSmartGal smart]] member on her team of {{Action Hero}}es and serves as MissionControl, Barry on the other hand is the single superhero on his team which consists of geniuses who all serve as his MissionControl. This later gets subverted where more members get added to both teams' rosters, so Felicity isn't the sole genius and Barry isn't the sole field member.
* FragileSpeedster: Comparatively. Despite being more resistant to harm than the average person thanks to his super speed, Barry will still injure himself if he runs into something at said speed, as part of his inexperience.
* FreakLabAccident: See above: he [[LampshadeHanging warns Felicity]] about how to avoid them. Then, [[ForegoneConclusion as you may have guessed]], {{Irony}} kicks in and he is the victim of one.
* FreudianExcuse: He couldn't help his dad get acquitted of his mother's murder, so he when he gets his powers he ''jumps'' at the chance to help people over the city.
* FriendlessBackground: Prior to meeting Oliver and becoming the Flash, Barry's only friend was [[ChildhoodFriendRomance Iris]] with whom he grew up with. [[spoiler: Which makes him hurt even more when he realizes how he messed up the lives of [[CynicismCatalyst Cisco]] and [[JumpingOffTheSlipperySlope Caitlin]] after Flashpoint.]]
* FriendlyRivalry: With [[Series/{{Arrow}} Oliver Queen]].
* FutureBadass: If Thawne's 2024 news article is any indication.
* GadgeteerGenius: Not to the extent of Cisco, but he can put together some impressive tech.
** He will eventually create the AI Gideon, which will later be standard issue on all Time Master vessels.
** [[Recap/Supergirl2015S1E18WorldsFinest While he was on Earth-38 he created special ear plugs to counter out Silver Banshee's scream and helped the National City police devise containment cells for metahuman criminals.]]* GeekPhysique: In contrast to his muscular comic-book counterpart, Barry is a boyish-built guy and shows a fair amount of self-consciousness whenever he gets compared to more heroically built heroes such as Oliver Queen ("His arms are like, twice as big as yours...") and Hunter Zolomon's time remnant ("Your shirt looks so small on him...").
* GeniusBruiser: He gets to show off the "Genius" part a bit more on Supergirl's Earth than in his own series, as his biggest contribution aside from his speed are the gadgets and software he develops for the DEO. Barry is a certified genius in his own series as well, but rarely gets to show it off because of his teammates, who usually handle these aspects for him.
* AGodIAmNot: Executed beautifully in one line.
-->'''Mardon''': I didn't think there was anyone else like me. \\
'''Barry''': I'm not like you. You're a murderer.
* GoodFeelsGood: Barry ''loves'' helping people.
* GoodIsDumb:
** Not usually, but Barry has a blind spot when it comes to Eobard Thawne. Until he sees the headline that Mason Bridge, the reporter who's been going after Thawne is missing. Then he finally sees the painfully obvious.
** He once made a deal with Captain Cold thinking he could be trusted. It blew up in his face, big time!
** He did have his moments in his early days, like trying to punch a villain made of poisonous gas.
* HappilyAdopted: While adopted at an older age under distressing circumstances, Barry did end up being a true part of the West family. Reciprocated by Joe, who admits that Barry brought a lot of joy and warmth to the West household.
* HasAType: When looking at the likes of Iris, Linda, Felicity and Patty, he seems to be attracted to smart, perky and tough girls.
* HealingFactor: A side-effect of Barry's power, which speeds up his healing process.
** Comes in incredible handy in "Revenge of the Rogues". In order to defeat the Rogues, he needs them to fire their guns at each other. Ultimately, the only way to do this is to briefly endure their fire and ice blasts coming at him from each side before running out of the way. Given that the guns were absolute zero and absolute heat, this would have easily killed any normal human.
* TheHeart: Barry is this for the entire Series/Arrowverse.
* TheHero: Of the show, considering that the series revolves around Barry and his journey as a superhero.
* HeroOfAnotherStory: He is this by default every time he does a {{Crossover}} to the other shows.
* HeterosexualLifePartners:
** With Cisco. The two hit it off immediately as friends, functioning as each other's wingman and even briefly moved in together in Season 3. [[spoiler:They're so close that Barry asked Cisco to be his best man for his wedding with Iris]].
** With Oliver. Oliver was his first mentor and one of his inspirations for becoming a hero. While he isn't as close to Oliver as he is with Cisco, the rapport they share is strong enough that Barry is the only person that didn't know Oliver pre-island to call him "Ollie".* HisOwnWorstEnemy: It's been repeatedly stated that Barry himself is his own worst enemy, not who or whatever he faces. [[spoiler:This is taken to new heights with the reveal of Savitar being an evil future version of him]].
* HopeBringer: To the people of Central City. When he fully reveals his existence to the whole city, he embraces this. This can be especially shown in "The Man Who Saved Central City".
* HorribleJudgeOfCharacter: One reason why Barry grabs the IdiotBall a lot is because he has a tendency of seeing people in the best light. Besides Thawne, he also thought that Snart is a man of his word despite a huge criminal record and he didn't realize that the Arrow has no qualms about torturing people even though he's followed up on news about the Arrow and knows that Oliver has an extensive body count.
* HotScientist: Genius-level intellect and a day job as a forensic scientist? Check. Clear skin, styled hair, and abs? Double check.
* HurtingHero: Poor Barry has suffered quite a lot in order to become The Flash. First his mother was murdered and his father was wrongfully accused of her murder. Then he finds out that his mentor was in fact his Archenemy and the one responsible for his mother's murder. He is given a clear chance to save her life but ultimately has to let her die in order to create a StableTimeLoop. At the start of Season 2 he begins working alone after his guilt over Ronnie and Eddie's deaths. Then he finds out that Zoom was in fact "Jay Garrick" in disguise who proceeds to steal Barry's speed and then later on murder his father. And at the end of the season he finds out that the Man in the Mask is in fact the real Jay Garrick, the Earth-3 Doppelganger of his father which finally breaks him completely. By the end of the season he's so broken and riddled with despair that he decides to undo his mother's death just so he can have a modicum of peace.
* HyperAwareness: His brain can work at SuperSpeed, which allows him to perceive things more slowly than they really are. It automatically activates when he's running, though he can willingly use this ability outside of SuperSpeed if he needs to.
* IAmTheNoun: In the opening narration he refers himself as "The Impossible".
* IconicSequelCharacter: Was only introduced during the second year of the Series/{{Arrowverse}} but by the third year, he now has his own show which, near its SeasonFinale, is now wildly considered as a MorePopularSpinOff. By the fourth year, he practically becomes the entire franchise's SeriesMascot.
* IdiotBall: Grabs it occasionally when things are at their worst and can't see any better options
** In "Rogue Air" he made a deal with Captain Cold to transfer metahumans from the Pipeline to Oliver's prison on Lian Yu, naturally Cold double crosses him in the end.
** In "Flash Black", he outdoes himself by time traveling back to Season One to get Eobard Thawne help get faster. It actually works, but only after Barry majorly screws up and Thawne gives him what he wants just to get rid of him.
* ILetGwenStacyDie: A non-romantic variation, but the fact that he was unable to help either of his friends, Eddie or Ronnie, have him questioning whether or not he truly is TheHero Central City has made him out to be come the beginning of Season 2.** Adding to his hurt is that both men were the Fiancée and Husband of two of his best friends, Iris and Caitlin respectively, though neither of them blame him for what happened.
** Later applies during the weeks following his trip to Earth 2, where he was unable to save Earth 2's Joe, Jay and pretty much all of Earth 2 from Zoom and his minions after closing the breaches for good.
** Also applies to his mother and later on father the former of whom he had to allow die in order to create a StableTimeLoop and the latter who was murdered right in front of him without him able to do anything do stop it. At the end of Season 2 he decides to undo Nora's murder after getting thoroughly [[BreakTheCutie broken]] by the TraumaCongaLine he experienced.
* InASingleBound: By building up enough momentum, Barry can leap really high. He utilizes this in the first episode to save Joe and Eddie from falling debris.
* {{Intangibility}}: Learns how to do this in "Tricksters".
* IShouldHaveBeenBetter: Fast as he is, he's not fast enough to save everyone so when somebody dies on his watch, he takes it hard.
* IWantMyBelovedToBeHappy: Confesses to Iris, but is acting like this for the time being.
** Also his reasoning for letting Patty Spivot leave Central City to achieve her dream of being a CSI rather than revealing his secret to convince her to stay.
* ItsPersonal: Barry's relationship with his [[ArchEnemy Arch-Enemies]].
** Barry Allen and Eobard Thawne have been at war with each other over the course of several timelines, and their enmity is the most personal in all of the Arrowverse. Only Oliver's relationships with his respective Arch-Enemies come even close to the amount of hate Barry and Eobard have for each other. They would give almost anything to kill each other, but are unable to since their timelines are so heavily intertwined -- killing one at the wrong moment would wipe out the other from existence. This fact only makes them hate each other even more.
** Hunter Zolomon deliberately invoked this trope in Season 2 to make sure Barry got faster and faster for his own plans. By the end, it was so personal that Barry wanted to kill him with his bare hands (he let the time wraiths have Zolomon instead). Unlike his conflict with Eobard, the "personal" part is mainly confined to Barry's end. While Zolomon seems to resent Barry for suffering a similar childhood tragedy only to retain a somewhat stable home life with the Wests (unlike Zolomon, who was sent to an OrphanageOfFear), when it comes down to it, Zolomon messed with Barry ForTheEvulz rather than out of any desire to settle a personal grudge.
** Savitar ''claims'' this is the conflict between him and Barry, but other than trapping him in the Speed Force, there hasn't been much revealed about why that is. [[spoiler: Turns out that Savitar '''is''' Barry and he needs Iris to die to ensure his own existence.]]
* JackOfAllStats: His superpowers aside, he can function as TheMedic like Caitlin or a GadgeteerGenius like Cisco, but still isn't as strong as either of them in their respective fields. Then Julian waltzes in and shows he's not even the best there is at his own field, forensic science.
* JumpedAtTheCall: Very eager to use his powers to help people.
* TheKnightsWhoSaySquee: Even after he develops his powers, he still thinks [[BadassNormal Oliver Queen]]'s grappling arrow is cool and relies on him for support.
* TheLabRat: His day job at the Central City PD.
* LateForSchool: Or perhaps Late For Absolutely Everything. At first, though he likely won't have to deal with that for too long. Even with SuperSpeed he's still late to crime scenes, mainly because of other heroics.
* LetsYouAndHimFight: In ''Flash vs Arrow'', Barry has been hit with the HatePlague and they get into a fight. Ends in a draw, as the fight is interrupted before either can secure victory.
* LightningBruiser: Puns aside, he's super fast and can hit hard through either [[RapidFireFisticuffs throwing a lot of punches]] or his supersonic punch. When returning home from the Speed Force, he has almost literally become this, able to take Girder's hits and recover quickly.
* LoveHurts: He's flat-out told by Oliver that it won't end well with Iris and at the end of ''Flash vs Arrow'' she never wants to see The Flash again, but she changes her mind after the BigDamnHeroes moment he pulls against Captain Cold and Heatwave.
* LoveMakesYouStupid: His feelings for Iris cause him to make some really stupid decisions that often come back to bite him in the bud.
** Best example of this is in "Rogue Time," when Barry tries to flirt with Iris (even though he should have known better than to do something like that in different circumstances and in a different time line) and she says he is "too late," and then later Eddie punches him for trying to steal Iris from him.
** He seems to have gotten better about it in "The Trap," when he learns that he and Iris get married in the future and he doesn't try to steal Iris from Eddie. In fact it's Iris who brings it up in conversation, and they both muse what their lives would be like if Thawne hadn't screwed with them.
** In Season 3, [[spoiler: he proposes to Iris in an attempt to change the future where she's killed by Savitar - they weren't engaged in that future, when she finds out she breaks it off.]]
* TheMainCharactersDoEverything: He seems to be the ''only'' forensic scientist the CCPD has. But averted in Season 3, where he gets a very rude and insufferable coworker.
* TheMasqueradeWillKillYourDatingLife: He's learning this the hard way during his dates with Linda. Oliver Queen warns him as such in the first crossover.
--> '''Oliver''': Guys like us don't get the girl.
* MaybeEverAfter: With Iris, according to Gideon, and the article from the future, and her doppelganger on Earth-2, she at one time may change her surname to West-Allen. In the episode ''Trajectory'' Iris even makes a casual mention of a possible wedding between her and Barry, showing he's not the only one open to the idea.
** As of the end of ''The Runaway Dinosaur'' the two have become the OfficialCouple.
* TheMedic: The biochemistry knowledge he obtained in his forensics background evidently carried over to this, and it allows him to save Oliver's life when he first finds out about his SecretIdentity.
* MessianicArchetype: The Chosen One of the Speed Force, a tragic past filled with doubters, gaining true friends, family and loved ones, was believed to be dead in a attempt to regain his powers, but came back to save the worlds.
* MiseryBuildsCharacter: Brutally deconstructed; all the tragedies Barry face only make him weaker as they happen in such frequency that Barry has little time to process them: due to the traumatic circumstances of Nora's death it took a long time for Barry to finally accept her death, then Henry was murdered in ''same spot as Nora was'', and barely a year after Henry's death, [[spoiler:Savitar kills Iris which in a BadFuture was the last straw as it just '''broke''' Team Flash. When it's revealed that Savitar is a future version of Barry, it implies that all these events happening in such a quick succession facilitated his transformation into a TragicVillain, desperate to ensure his own survival even if it meant forcing his past self to suffer the same tragedy of losing the love of his life]].
* MoralityPet: To Oliver Queen. One of many Oliver has.
* MotorMouth: It's hard to get him to stop once he starts talking.
* MrFanservice:
** He doesn't have a shirt on much of the time whenever Star Labs is running tests on him. Lightning gave him abs!
** In "Plastique" he ''strips down to his boxers'' in an alley. Yeah, "[[DoubleMeaning The Flash]]" indeed.
* MyFutureSelfAndMe: Being a speedster capable of time traveling, this has happened on a few occasions.
** Back on the night of Nora Allen's murder, a young Barry sees his mom being surrounded by two speedsters, with one of those speedsters being a future Flash who proceeded to save young Barry's life.
** In "Fast Enough", Barry travels back to the night of his mother's murder, where there were three Barrys. There was Barry from the future trying to save kid Barry from the past, and the present Barry trying to save his mom from being murdered by Reverse-Flash. However, Future Barry signals present Barry not to intervene.
** In "Flashback", Barry travels back to a year ago during the episode "The Sound and the Fury", where he sedates his younger self and attempts to take his place to consult Dr. Wells, however past Barry eventually awakens and returns, leading the two Barrys to have a very amusing interaction.
** In "The Present", Barry travels to the future by accident and witnesses Savitar killing Iris, while a Future Barry isn't fast enough to stop this from happening.
** In "The Once and Future Flash", Barry travels to the future and meets the Future Barry of 2024, who's a lot more grimmer than his younger self due to having to face the loss of Iris.
** In "I Know Who You Are", it's revealed [[spoiler:Savitar is actually a Future version of Barry Allen who has become corrupt and evil, which means the entire season Barry has been fighting his future self.]]
* MyGreatestFailure:
** His trusting of Eobard Thawne, may also be a huge one, since he believed it is what lead to the deaths of Eddie, Ronnie and a lot of other people in Central City.
** In the same vein, his trusting of Hunter Zolomon, as this lead to the death of his father.
** In Season 2 he regrets not saving his mom back when he had the chance. He rectifies it at the end of the season. Which unfortunately leads to an even greater failure ....
** Flashpoint, every time he finds out another shift in the timeline that causes his friends pain, he is [[ItsAllMyFault always willing to take the brunt of the blame.]]
* NerdActionHero: He'll geek out about science and zombie movies and then save your life with his powers.
* NerdsAreSexy: Considering that he is a scientist who is a combination of {{Adorkable}} and MrFanservice, Barry definitely qualifies as a very attractive nerd.
* NiceGuy: Goes along with his being so {{Adorkable}}; he's very friendly and empathetic, and he'll put his life on the line for strangers and friends alike, and is quite possibly, aside from [[Series/{{Supergirl}} Kara]] the nicest hero in the Arrowverse. But, as always, BewareTheNiceOnes.
* NiceJobBreakingItHero: Has a terrible habit of being emotionally provoked, intentionally or otherwise, into causing potential [[ApocalypseHow extinction level events]].** In the season 1 finale, Eobard Thawne proposes a plan — using Cisco's Rip Hunter-esque time machine, Barry goes back in time and saves his mom and in turn Eobard returns to his own time, the entire story between them retconned from time. Barry agrees, travels back to the past, then backs out of saving Nora at the last minute when another future Barry warns him off, returns to the present and stops Thawne from going home. This leads to a fight in which Eobard has Barry on the ropes until Eddie shoots himself to [[{{RetGone}} erase Eobard's "current" existence]]. Thawne then disappears…and [[ApocalypseHow/{{Class 6}} a black hole, a singularity forms over the city]], from the resulting paradox. Barry tries to stop it with his speed but can only slow it down at best, so Ronnie has to sacrifice himself to close it completely by defusing Firestorm within the event's center. As Nice Jobs go, this is a particular crown jewel, and let's not get into how it lead to opening Earth-1 to an even more dangerous speedster and his minions, turning the events of Season 2.
** When Zoom murders Henry before his eyes right before the season 2 finale, Barry is angered and provoked into agreeing to a race with Zoom… which will generate enough energy into a stolen pulsar device [[ApocalypseHow/ClassX5 to destroy every other universe]]. It takes the rest of the team figuring this out, holding him back, going through a failed alternate plan, and voicing their concerns for him to regain a sound enough mind to figure out how to actually beat Zoom and avert the disaster.
** Right after the above situation was cleared up, Barry is so thoroughly broken at this point that he goes back in time and follows through on saving his mom from Thawne. This AFTER it's been explained dozens of times (and demonstrated a few, for those who watch Series/LegendsOfTomorrow) how messing too far with time is a terrible idea, and AFTER the Speed Force outright told Barry that his mother's death and his becoming the Flash led to his saving countless innocents. Even those who didnt't know [[{{ComicBook/Flashpoint}} the comic book version of what happens when he does this]] figured out this wouldn't end well...
** So, how not well did things end? The West family and Team Flash are all screwed up. [[spoiler: Joe is a drunk who's always hung over and late for work and on the verge of being fired. Cisco made a fortune off an invention, S.T.A.R. Labs is Ramon Industries now, and he has a new girlfriend/assistant…but he's incredibly pompous, pretends not to care about people, dislikes Wally and Iris, doesn't know Barry or Caitlin, and speaking of which, Caitlin doesn't work there, she's an eye doctor. Why does Cisco dislike Wally and Iris? Wally is Kid Flash, Iris is using her reporter connections to feed him info, and they came to Cisco for help building Wally's suit before but he doesn't want to get involved. Meanwhile, Barry using his speed also accelerates his assimilation into the new timeline, meaning every time he thinks of an old memory afterwards he ends up forgetting it and blanking out. He helps Wally take down The Rival (Edward Clariss) but Wally is near-mortally wounded in the process. All the while Eobard, from the speed-dampening cell Barry put him in, keeps taunting Barry about how he screwed up everything.]] Once Barry finally sees he didn't stop [[spoiler: his loved ones' suffering]], he agrees to let Thawne go back and kill Nora again in order to "fix" things. However…** Because Barry was [[spoiler: collapsing due to his memory blanks, Eobard got to be "the hero", meaning ''the Reverse-Flash now had free reign to make subtle changes'']], ensuring that Barry's misery just keeps on going even after the timeline was [[spoiler: mostly]] restored. The end results were: [[spoiler: Joe didn't tell Iris about Francine; she found out on her own and has been pissed at him for months. Cisco's brother Dante was killed in a car accident, he's still grieving over it, and he's mad at Barry's refusing to change the timeline to save Dante. John Diggle doesn't have his baby daughter Sara, he has a son, John Jr., instead, the same one who becomes Connor Hawke by 2046 according to the Legends' visit to the Star City of that hypothetical future — a post-apocalyptic gangland dystopia. Also, a strange masked man called Dr. Alchemy is finding the Flashpoint-exclusive metahumans (first one being The Rival) and experimenting on them to give them back their powers. This ''will'' affect Wally in the future, but since the others don't want to know about their Flashpoint lives he ''doesn't'' tell them this immediately. The resulting leftover skin husks are being investigated by a new partner of Barry's at CCPD who's frosty with him because can tell he's hiding something[[note]]but doesn't know that something is him being The Flash[[/note]] and therefore doesn't trust him. And speaking of frosty, Barry doesn't learn about this for awhile, Caitlin is becoming Killer Frost]]. He also wanted to go back in time and "fix" these things too, but [[spoiler: was intercepted by Jay Garrick, his dad's doppelganger, who had to teach him from experience about moving forward responsibly instead of constantly trying for do-overs and just making everything worse]]. And then Season 2 of ''Series/LegendsOfTomorrow'' shows even more horrible consequences: [[spoiler: because Eobard Thawne never died in this new timeline, he formed an alliance with Damien Darhk and proceeded to nuke Manhattan in 1942, extending World War II by a couple of years and millions of casualties. The Legends had to go back to that time period to prevent it from happening despite the warnings of Hourman, the results of which caused Rip Hunter to go missing and nearly killed the rest of the Legends. Not to mention that Darhk and Thawne are just half of a Legion of Doom with Malcolm Merlyn and a version of Leonard Snart who never became a hero]]. Then it turns out later [[spoiler:his time travel mess-ups also resulted in a calamity on another planet whose victims considered it an act of war and responded with an ALIEN INVASION OF EARTH.]] When Barry Allen makes a mistake, he goes big.
* NiceShoes: Barry seems to have a thing for Converse All-Stars.
* NoHoldsBarredBeatdown: His battle with Oliver during the very first {{Crossover}}, a BrainwashedAndCrazy Barry lays one on Oliver through a [[RapidFireFisticuffs flurry of punches]].
* NoodleIncident: There was one time as a kid where he tried out for his school's football team. He and Joe have agreed [[LetUsNeverSpeakOfThisAgain never to speak of it]]. * NotSoSimilar: From Eobard Thawne. Despite their many similarities there are some key differences, Eobard is a fatalist while Barry is a firm believer in that you can ScrewDestiny.
* NowOrNeverKiss: Knowing that what he is about to do, ''(actually stop Thawne from killing his Mom)'', the entire time line will change, and the next time he sees her, things will be radically different between the two, he seizes the opportunity to finally share a real kiss with Iris, and let her know how much he loves her one last time, before he leaves.
** Later shares this with ''Flashpoint'' Iris, knowing that allowing Eobard to ''fix'' the timeline will result in her being RetGone'd, he shares one with her before leaving Flashpoint behind.
* OddFriendship: With Oliver Queen, AKA ''The Series/{{Arrow}}''. They're not far apart in age (Oliver is about 4 years older), but Oliver's age and experiences make him the older, gruff, almost unwilling mentor to Barry's eager kid. In their first crossover (not the backdoor pilot), they both feel out of place in one another's series, as Oliver is the brutal cowl and Barry the idealistic cape. They're the DC Television Universe equivalent of Bruce Wayne and Clark Kent.
* OhCrap: When he travels back in time to the previous night in "Out of Time", he is visually perplexed and frightened. Same with "Flashpoint", the aftermath of "Flashpoint", et al.
* OlderThanTheyLook: Earning him the nickname "Babyface". He's 25 at the start of the series.
* OmnidisciplinaryScientist: Barry seems to be the only crime scene/forensics tech CCPD has. In "The Man in the Yellow Suit" he mentions that he had a double major in physics and chemistry in college.
* OneHeadTaller: At 6'2", he towers over Iris, 5'4", his primary love interest.
* OneManArmy:
** In the ''Arrow'' Season 3 finale, he's able to take out the '''League of Assassins''' like they were nothing.
** He was able to defeat dozens of Zoom's metahuman army during the penultimate episode of his show's second season.
* OneTrueLove: Iris West. Their Earth-2 counterparts are married, and Flashpoint!Iris fell for Barry almost immediately. While Barry is capable of feeling genuine attraction to other women and can even fall in love with someone else, in the end, Iris is the love of his life. He can't bear the idea of living without her, be it as a friend or lover.
* OOCIsSeriousBusiness: To characterize how much despair Henry's death has caused him and how much he has come to hate Hunter Zolomon, Barry outright admits to Joe that he doesn't want to just kill Zoom -- he wants to make him ''suffer''. Considering that Barry is usually merciful and only resorts to killing as a last resort, this was enough to alarm the rest of the team into locking him up in the Pipeline until Barry calmed down.* OpenSecret: His SecretIdentity borders on this as the series goes on. One character (who runs a company that competes with Star Labs) casually reveals that she knows Barry is TheFlash, and when he asks how the response is "I'm not stupid". It doesn't help that Barry is pretty casual about revealing his identity to people anyway, often for reasons as trivial as boosting their morale.
* ParentalAbandonment: Barry's mom was murdered when he was eleven, and his father was convicted for the murder.
* PlatonicLifePartners: Barry this relationship with Caitlin; despite being close friends, both have other love interests and have no romantic feelings for each other. Aside from a few occasional ShipTease moments, they never show any intention of wanting to get together. [[spoiler: May not be the case as of season 3 onwards, as Caitlin shows a lot of resentment for Flashpoint turning her into Killer Frost, and when Killer Frost takes over completely, Barry soon learns that she joins Savitar. Needless to say, [[{{Understatement}} siding with the speedster that's going to murder his fiancee probably won't do wonders for their relationship]].]]
* PopCulturedBadass: The fastest man alive likes "Pokerface" by Lady Gaga. He's got a blog according to Eddie and a Facebook account according to Cisco.
** He also has a zombie movie scale and even rates one film at a 4.
--->'''Iris:''' There's a zombie movie scale?
* PowerIncontinence: He has great deal of control over his abilities....except his ability to travel through time. While his future self is implied to be able to time travel at will, present day!Barry can't. It takes a disaster like Weather Wizard's tidal wave to push into a state of emotional distress so he can go fast enough to do it, and even then he really has no control when he'll go back and it's less like he's going back in time and more like he's rewinding time. The only time he exhibits more precise control when he went back to save his mom, and that was due to the controlled environment of the the Particle Accelerator and Thawne's coaching.
* ThePowerOfFriendship: The STAR Labs gang realizes that his devotion to his loved ones are what give him greater strength.
* ProperlyParanoid:
** His gut instinct on meeting Hunter Zolomon's time remnant was to throw him in the Pipeline. Turns out he was right.
** He often worries about his loved ones' safety, since his various enemies have no qualms kidnapping or killing them.
* RankUp: Averted in the first five episodes of Season 3 in his day job as a CSI tech after he fixes the timeline; were despite his experience and intelligence he's been demoted to junior lab tech by his new coworker Julian, who's in charge of investigating all metahuman crimes and forces Barry to do all of the mundane paperwork while he does all the lab tests. Eventually he and Julian become friends and they act as equal partner.
* RedBaron: Appropriately, the Scarlet Speedster/Knight. Also, the Fastest Man Alive. The Man Who Saved Central City is also frequently used in Season 2.
* RedIsHeroic: Barry's entire Flash costume is red.
* RedOnesGoFaster: If the color of his costume is not obvious enough. It's actually downplayed a lot, with several other speedsters with different color outfits (Reverse-Flash and Wally - yellow, Zoom - black, Savitar - silver), all being faster than him at some point.
%%* RedOniBlueOni: The Red to Thawne's Blue
* RelatedInTheAdaptation:
** In this version, he was adopted into the West family after his mom's death and his dad's falsely-charged imprisonment.
** {{Inverted|Trope}} with Eobard Thawne's ancestor as he has no relation to Eddie, whereas Malcolm Thawne was Barry's identical EvilTwin.
* RelativeButton: Mess with Iris as Girder learned, or either one of his Dads as Weather Wizard and the Trickster found out respectively, and you will be sorry.
* RippleProofMemory: He's able to remember how time was before he changed it.
* RoaringRampageOfRevenge: After Zoom kills his father (in the spot where the Reverse-Flash murdered his mother no less), Barry straight up ''loses it'' and beats the shit out of his time remnant. The rest of the episode has him transitioning between this and TranquilFury, to the point that the team locks him up in the Pipeline for a time because they believe his anger would do more harm than good.
* TheRunaway: After his dad was convicted, and he was given to Joe he would runaway a lot trying to see his dad.* SadClown: According to a comment from executive producer Greg Berlanti.
-->'''Berlanti''': Barry lost his mother at a very young age, his father was sent to prison for murdering his mom, he went through a lot of stuff - on the surface he's [[StepfordSmiler bubbly]] and [[PluckyComicRelief upbeat]] and seems like an [[NiceGuy optimist]], but deep down maybe there's no hope left.
* ScienceHero: Barry works in a science lab and he saves innocent people on the side using his science know how. Best shown in his debut episodes on ''Arrow'' and his on his time on [[Recap/Supergirl2015S1E18WorldsFinest Earth-38 with Supergirl without his support team.]] He just prefers to be collaborative with his heroics.
* SecretIdentity: According to Grant Gustin, Barry will try to keep his activities as the Flash secret from certain people but most of the people in his social circle will know the truth.
** By the end of the 1st season his identity barely qualifies as "secret", as literally every main character on the show, several villains, and at least four characters from ''Arrow'' all know who he is.
** Gets even worse in Season 2 with Wally, Jax, two ex-girlfriends (one of whom Barry revealed his identity to just to give her a morale boost), the BigBad (who discovered his identity before they even met), the head of a rival science lab (who thought his secret identity was so obvious she didn't bother explaining how she knew), a former villain who got retconned into an ally due to time-travel, and who knows how many people from Earth-2 all knowing who Barry is. It's starting to border on EverybodyKnewAlready.
* SecretKeeper: Mutually with Oliver Queen[=/=]The (Green) Arrow. This extends outside their superhero schtick, as he's the first person Oliver tells that he fathered a child out of wedlock about a decade prior. Felicity found out too, but Barry's TimeTravel negated her finding out about it and postponed it to a later time.
* SeekerArchetype: Was this to some extent before he got his powers -- seeking answers about "the impossible" to prove his father was innocent of his mother's murder.
* SelfDeprecation: Mocks the name "Leonard", saying it's nearly as bad as "Bartholomew", which is his given name.
* SelfFulfillingProphecy: His future incarnation went back in time to save his mother's life from the Reverse-Flash, yet this action created the skirmish that ended with Reverse-Flash killing her. Even so, this is probably a good thing—the one Reverse-Flash was trying to kill was ''Barry himself as a little boy''.
* SensitiveGuyAndManlyMan: Every time he and Oliver are together, he's usually depicted as the sensitive one.
* SherlockScan: Particularly evident in the early episodes, especially the pilot before he became the Flash. As Barry looks over the crime scene, the clues he spot are accompanied by visual text to show Barry's observations (much like how the TropeNamer [[Series/{{Sherlock}} does so]]). He was able to discern exactly what type of car the Mardon brothers used in their getaway from a robbery from analyzing a tire track, and figure out a vague location from a piece of excrement mixed with the track; all within a minute and without the use of any equipment.* ShipperOnDeck:
** He notices the budding interest between his father and Dr. [=McGee=]. Unfortunately, Zoom puts a stop to it from becoming anything more.
** He's enthusiastic to see Joe's budding interest in DA Cecil.
* ShipTease: With Felicity Smoak in ''Arrow''. Also a few times with Caitlin. Both ships are sunk once Caitlin gets married and Felicity ends up with Oliver. More recently a brief one with [[Series/{{Supergirl 2015}} Kara Danvers]], though it goes nowhere due to her being on another Earth.
* SingleTargetSexuality: Subverted - although he's been in love with Iris since they were children (a possible case of LoveAtFirstSight, even), he did show a genuine attraction to Linda Park and seems to acknowledge his chemistry with Felicity Smoak; he also mentions a girlfriend he had back in high school. It's just that his love for Iris is too great to get over her, and thus his relationships with other women don't last.
-->'''Barry''': I really do feel a lot for you Linda. It's just.....
-->'''Linda''': .....Just not as much as you feel for someone else (both look at Iris).
** Averted to some degree with Patty Spivot. While he does admit that he is still in love with Iris, and never explicitly says that he loves Patty before she leaves, it's implied that he's open to the possibility of falling in love with her, and seems genuinely sad that it didn't work out.
* SmugSuper: Occasionally displays traces of it.
-->(Regarding the [[{{Series/Arrow}} salmon ladder]]) Honestly, I don't know what's so hard about this.
* SociallyAwkwardHero: He has trouble relating to other people.
* SpearCounterpart: To [[Series/{{Arrow}} Felicity Smoak]]. Both are {{Adorkable}}, have a tendency to babble, and are brilliant in their respective scientific fields.
* SpikyHair: It's like it's always in clay dough.
* StoryBreakerPower: Everytime he crosses over to ''Series/{{Arrow}}'' since becoming The Flash, he has a tendency to fix problems literally more faster than Team Arrow usually does.
* StaticCharacter: Despite having gained a greater control over his powers, Barry changes very little mainly because of his constant AesopAmnesia regarding LoveMakesYouStupid and personal lost which in a way have stunted his maturity.
* StrongAsTheyNeedToBe: Barry has shown incredible feats in speed. Including being so fast that he was able to punch a hole in time. He was even so fast as to take Weather Wizard from his hideout all the way to STAR Labs before the latter even knew what happened. Yet he will still somehow not be fast enough to take out the any other VillainOfTheWeek in a similar manner, even when they have far less dangerous abilities, if for no other reason than that it would be very boring to the viewers.
** Then, again it my be to show his inexperience that he is slowly growing out of, and Barry taking Oliver's advice about not rushing into every situation without a plan, or risk doing more harm than good.
* StrongFamilyResemblance: His adult self is stated to look almost exactly like his grandfather did as described by Nora Allen when Barry time travels into the past.
* SuperheroOrigin: His is told in the ''Arrow'' episodes "The Scientist" and "Three Ghosts", and is expanded upon in the pilot episode.* SupermanStaysOutOfGotham: In his first {{Crossover}} since becoming The Flash, he and Oliver had a lot of discussion regarding their different approach in heroics. They eventually sort things out.
* SuperpowerLottery: Easily the Arrowverse's most powerful superhero of Earth-1 and, short of Savitar (and even then his future self sealed the monstrous speedster away), most powerful character overall. [[spoiler:And then Savitar is revealed to be Future Barry, reestablishing that Barry Allen truly is the fastest man alive]].
* SuperSpeed: His primary ability.
* SuperSpeedReading: Uses it to help Caitlin look for clues on the "F. I. R. E. S. T. O. R. M." project.
* TalkingIsAFreeAction: [[DefiedTrope Denied.]] He frequently takes the time to talk to his opponents when he has them down but not beaten…and almost just as frequently [[RealityEnsues gets made to pay for it]].
* TallDarkAndHandsome: He stands 6'2.
* ThouShaltNotKill:
** He prefers saving lives to taking them. It doesn't matter if a person is some innocent bystander or the VillainOfTheWeek; he'll try to save them.
** However this is averted in Season 2 with the Earth-2 Metahumans -- specifically Atom Smasher and Sand Demon. However this is a special case: because a) they're far more dangerous than Earth-1 metahumans, b) they each have an Earth-1 doppleganger so they can't send them to Iron Heights without raising awkward questions, nor can they send them back to Earth-2, c) killing Sand Demon was an accident on Barry's part.
* TokenWhite: He is HappilyAdopted to the African-American West family.
* TookALevelInBadass:
** Does this during his fight with Clyde Mardon.
** Runs across the surface of the bay in order to carry Plastique far enough away from Central City so she doesn't destroy the city when she explodes.
-->'''Caitlin''': "You just walked on water. Puts you in some [[JesusChrist pretty interesting company]]!"
** Goes even further after losing his powers to Blackout and regaining them to new heights. Before then, he had to make a massive running start to break the sound barrier. Afterwards, he is able to FlashStep to avoid ''lightning''. Even Caitlin notes that his cells are generating more energy than they were before.
** In "Out Of Time", he needs to protect the city from a tidal wave headed its way. The solution, according to Caitlin? Run back and forth on the beach to generate a second tidal wave in the opposite direction to cancel the first one out. However, this requires going faster than he's ever had to before, to the point where he unintentionally goes back in time. ''Barry can now travel back in time.''
** In "Tricksters", Thawne vocally instructs him how to vibrate his body in order to phase through solid matter, a technique that Thawne himself had already demonstrated in the previous two episodes. Then at the end of the episode his AwesomenessByAnalysis kicks in and he remembers the aforementioned detail.
** His fight and victory against Eobard/Reverse-Flash in "Reverse-Flash Returns" is definitely one, after spending pretty much all of Season 1 being pummeled by him.
*** Though this is somewhat justified since not only is Barry more experienced than he was in season 1, but Eobard Thawne is ''less'' experienced, due to this version being from an earlier point in Eobard's life. From ''Eobard's'' perspective, he's actually the one who [[TookALevelInBadass takes a level in badass]] and defeats The Flash.
** By season 3, Barry has reached [[Film/XMenFilmSeries Quicksilver]] levels of speed, and is capable of redirecting bullets from multiple gun shots, ''midflight''.
* TookALevelInJerkass: Briefly in Season Two, as he's still dealing with the fallout of Season One. He goes back to cheery self soon enough though...mostly, since some damange is still there.
* TrappedInAnotherWorld: He finds himself stranded on Supergirl's Earth for a few days after accidentally running fast enough to break the dimensional barrier.
* TwinkleInTheEye: It is quickly becoming a trademark that whenever the Flash is about to do something utterly ridiculous with his speed, lightning bolts are seen sparking in his eyes.
* TwoFirstNames: Being a Creator/DCComics based character, he has a last name that is traditionally used as a first name.* UniquenessDecay: Originally the very first speedster of his world (or at least the first one known to the public), but it didn't take long until a whole lot more appeared. His claim of being 'the fastest man alive' also usually only holds water for a short period of time.
* UnluckyChildhoodFriend: Other than his father being framed, being this is his personal dilemma. He seems to be working this out as of episode 12.
** Averted by ''The Runaway Dinosaur'' as he and Iris finally decide to get together.
* UnskilledButStrong: Barry has his super speed, but he doesn't have a lot tactical or martial arts training. This tends to let him get hit by surprise attacks a lot. [[BoxingLessonsForSuperman This gradually gets averted over time]], given that Oliver has been training him.
* WeirdnessMagnet: Well, not so much a "magnet" since he readily goes ''looking'' for the weirdness. To be fair, he never thought he'd actually become the [[SuperSpeed weirdness]] in the process.
* WellDoneSonGuy: Given that he has three father figures (in the first season, Joe West, Henry Allen, Eobard Thawne), he gets a lot of this. However, it's also frequently inverted, with Barry telling Joe and Henry how much they mean to him, especially Joe.
* WhatTheHellHero: Delivers this to Thawne, calling him out on his ManipulativeBastard tendencies and general selfishness.
* WhatHaveIDone: Has this reaction, [[spoiler: after seeing all of the ramifications he's caused to the timeline when he created Flashpoint.]]
* WildCardExcuse: Caitlin Snow comes up with "Lightning Psychosis" as a way of explaining all his strange behavior.
* WillfullyWeak: It's indicated several times that he holds himself back due to combination of self-doubt and the bad memories of his mother's death, combined with a subconscious awareness of how dangerous his powers are.
* WindmillCrusader: How Joe and perhaps the entire CCPD thinks of him, before he got his powers.
* WouldHitAGirl: If there's a female criminal with evil intent, Barry doesn't discriminate against gender.
* TheWorfEffect:
** To show off how dangerous an evil speedster is, they tend to be faster than Barry. Zoom and Savitar in particular stand out -- Zoom ''decimated'' Barry in their first fight, temporarily crippling him. Savitar was so fast that Barry running at super speed was slow motion to him, and he ruthlessly curb-stomped Barry in their first and second fights (though he didn't beat him savagely like Zoom did).
** Was on the giving end during the "Invasion!" crossover. [[spoiler:Every single hero except him and Oliver were brainwashed by the Dominators, forcing them to keep the others at bay until they could jam the signal. Barry quickly took out Mick, Ray, ''and'' Firestorm, and was able to match and manipulate Supergirl into destroying the signaling device]]. For all his faults, there ''is'' a reason why Barry is one of the two top heroes of the Arrowverse.* WorldsStrongestMan: Just like how Oliver Queen is the WorldsGreatestWarrior, Barry Allen is, by far, the most powerful superhero in all of Earth-1, and has the potential to be the strongest character in all of the Arrowverse. [[spoiler:This is only reinforced when Savitar, without a doubt ''the'' most powerful speedster/character ever introduced on the show, is confirmed to be a future version of Barry]].
* WorthyOpponent: What Hunter Zolomon/Zoom came to see him as by the end of season 2, especially after learning about the similarities between the two of them.
* YouAreBetterThanYouThinkYouAre: Even after he gets his powers, he still has doubts as to his capabilities in part because of Joe's disapproval of his heroics.
** In a conversation with Caitlin he admits that he thinks that best part of him is the Flash, and not his civilian identity.
--> '''Caitlin:''' With or without your speed, you're still you Barry.
--> '''Barry:''' No I'm not. I'm not the best version of me.
** Gives one of these to Oliver when he feels that what he does as the Arrow is consuming him. Barry assures Oliver that he can inspire people not as the Arrow, but as Oliver Queen.
* YouAreInCommandNow: It's revealed in Season 2 that Eobard Thawne left S.T.A.R. Labs to Barry in his will.
* YoungerAndHipper: A fair bit younger than Barry Allen is usually depicted as. It's explained in-universe that Eobard Thawne made the particle accelerator accident that gave him his powers occur nearly a decade earlier than it was supposed to. This younger Barry also relates better with the target audience of teenagers and young adults.
* YoureNotMyFather: After Joe comes down hard on Barry for risking his life by fighting other metahumans and engaging in dangerous heroics, Barry fires back by saying he is not Joe's kid and that his father is still sitting in prison for a crime he didn't commit.
** Later in a CrowningMomentOfHeartwarming, Barry lists all the things Joe ''has'' done for him and says that while Joe's not his father, he is a "Dad".
