!Season One
[[folder: Episode 1: Pilot]]

* The flashback that shows a child Barry getting beaten up by some bullies. The reason? Because he stood up to them for picking on some other kids. He emerges without any bruises, and his Mom later reveals that he won.
* The S.T.A.R. Labs team testing Barry's powers. They don't expect much..until he begins clocking in at 200 mph and blows away the canopy they set up.
* Barry cancelling out Mardon's TornadoMove at the end of the pilot is awesome both in-universe [[VisualEffectsOfAwesome and out]].
** [[CrowningMusicofAwesome The music definitely helped the scene too]].
* The moment Barry catches the piece of debris headed for Joe and unconscious Eddie, then tosses it off and standing up to reveal himself in The Suit and Mask for the first time.
* The fact that ComicBook/CrisisOnInfiniteEarths gets mentioned at the end of the pilot. Making this the first time in non-comic media that any Crisis has been so much as hinted at.
* Oliver's RousingSpeech about how Barry can be even more of a hero than him, topped by giving the Flash his name.
** To say nothing about how the scene ended with [[CrowningMusicOfAwesome a combination of both their theme songs]].
* Shortly after Barry gets his powers, he sees Mardon driving in a getaway car. After he and Iris get out of the way, what does he do? He doesn't stop to think, he doesn't hesitate, he just runs after him with the powers he barely even understands yet. The lightning bolt chose well.

[[folder: Episode 2: Fastest Man Alive]]

* Flash running through the giant mass of Multiplex's clones [[Film/TheMatrix Matrix]]-style.
* Thawne stating that the Flash must be protected, then stabbing Stagg who was talking about harnessing the Flash's powers after having seen the Flash in action.
* Flash [[BulletDodge dodges a bullet]] for the first time.

[[folder: Episode 3: Things You Can't Outrun]]

* Ronnie Raymond's HeroicSacrifice. The moment the particle accelerator begins to fail, he straight-up volunteers to use his expertise to redirect the explosion. He saves countless lives in exchange for losing his '''one'''.
* Barry's first confrontation with The Mist. He gets exposed to the toxic gas, his next course of action? ''Running'' all the way back to Star Labs so they can extract a sample from his body and create an antidote. Bear in mind, ''he can't breathe and is dying''.
* In the opening scene, Barry pulls a guy being chased by the police out of his car, puts handcuffs on him, and delivers him right into the back of the squad car chasing him - in the time it took Iris to take one phone call with Eddie. Bookended when he snatches a knife from a mugger and leaves the woman being mugged holding the knife, all in an instant.
* Caitlin facing her fear of going down into the Particle Accelerator deserves some mention. Bonus points for Barry agreeing to accompany her.

[[folder: Episode 4: Going Rogue]]

* Barry is now able to simultaneously play Operation, ping pong, and chess, winning two of them.
* Captain Cold is able to get away from Barry twice (one without his cold gun), and then nearly kills him at the end of the episode. He figures out Barry is more concerned with saving people than stopping him, so he endangers a train full of people, and has proven himself to be the most dangerous villain so far.
* When Cold derails a train, the cars flip and fall out of control. Barry is able to save everyone by picking them up, running them out and then going back for more at lightning speed. He's moving so fast he might as well be ''teleporting.''
** No, we need to emphasize this. The train derails, we go to bullet time... and ''while in bullet time'', '''''he's still moving too fast to be seen'''''.
* Cisco successfully bluffing Captain Cold into backing off by pretending a vacuum cleaner is an upgraded version of his gun. Even when Cold points out he's clearly never killed anyone, the guy is able to keep his cool enough to make it believable.
* Everyone seems to hate Cisco's code names for the villains, but when he calls Snart "Captain Cold" during their standoff, the latter can't help but give an affectionate smirk, apparently getting a kick out of the title.
* A small but notable one for Captain Cold (who, remember, is a [[BadassNormal completely unpowered man]]). At the end of the episode he first casually boards a speeding train and then, just as casually, jumps off it ''while it's crashing.''

[[folder: Episode 5: Plastique]]

* Barry runs up a building (And back down again) to save a falling window cleaner.
* Barry talking Plastique down, only for her to be shot and killed by General Eiling. As her explosive powers begin to overload her body, Barry picks her up and runs across water to get her out of Central City.
* When Eiling confronts Thawne over sending Plastique to kill him, Thawne doesn't even need to get out of his chair to convince the general to back off.

[[folder: Episode 6: The Flash is Born]]

* Just before launching on his way to his mach punch, Bary takes a three point stance and his eyes flash with yellow lightning.
* Barry's Mach Punch!
--> '''Cisco''': ''[[AudienceSurrogate SUPERSONIC PUNCH, BABY! WOO!!]]''
* Iris taking the finishing swing at Tony.
* Barry reveals his identity to an incarcerated Tony, not only to let the JerkJock know who beat him, but to give him a TheReasonYouSuckSpeech about how Tony is nothing but the same elementary school bully who has wasted a powerful gift.
* Barry comes up with an especially sly way to get the public onboard with his preferred superhero name, contriving to mention the word "flash" while talking about the Streak with Iris so she'll put it in her blog.

[[folder: Episode 7: Power Outage]]

* Blackout's CurbstompBattle against Girder.
** Before his death, Tony punching Blackout across the room and pulling a NoSell against a blast of electricity. He may not have lasted too long, but he did put up a fight against Blackout.
* Barry outracing lightning from across the room and saving Thawne, followed by overloading Blackout.
* Iris taking out Clock King.

[[folder: Episode 8: Flash VS Arrow]]
* Flash VS Arrow in a downright epic street fight!
** This is also awesome on a meta level, as they seamlessly combine ''The Flash's'' special effects with ''Arrow's'' fight choreography.
* Thawne deducing the Arrow's identity in less than a day once he decides to get serious about it. FridgeBrilliance kind of nullifies this though, since he probably just used his future computer to figure it out.
* With the Flash and the Arrow teaming up, the outcome is such a foregone conclusion that we cut straight to Bivolo being put in the Pipeline.
* During TheStinger, two crooks try [[MuggingTheMonster robbing]] someone who turns out to be alive and with superhuman fire powers.
* Oliver's method of teaching Barry to be more aware of his surroundings: He challenges Barry to avoid being shot, and while Barry easily catches the arrow Oliver himself fires, he runs straight past two automatic crossbows hidden in the grass which both get him in the back.
** Which then gets a super sweet callback as Barry catches the arrows Oliver had set up to repeat the trick during the street fight. "Fool me once." Then he gets a flechette in the leg. The Arrow landed a hit on a rage-maddened Flash!

[[folder: Episode 9: The Man In The Yellow Suit]]
* Reverse Flash's fights with The Flash are awesome, and the character is very scary and effective-as a good villain should be.
** During their second fight, Barry saves Joe and Eddie from Reverse Flash, and then is himself [[BigDamnHeroes saved]] by Firestorm, who blasts RF like a flamethrower. Firestorm then flies away with awesome trails of fire behind him.

[[folder: Episode 10: Revenge of the Rogues]]
* Barry has been training to increase his speed, and at the beginning of the episode, we catch up with him dodging missiles. Except he's now gotten so good that he opts to instead ''catch'' one and throw it back at the drone, in the process freaking Thawne out so much that he almost jumps out of his chair.
* This exchange from when Caitlin is being held prisoner by the Rogues.
-->'''Caitlin''': You're sick.
-->'''Heat Wave''': You ever think you're all the sick ones?
-->'''Caitlin''': [[ShutUpHannibal Not really, no.]]
* The Flash's epic fight with Captain Cold and Heat Wave, which combines with his public reveal to make the police quickly accept him as a hero.
** Ending the fight by slowing down, [[DeliberateInjuryGambit deliberately letting himself get hit by their weapons]], in order to cross the streams and cancel them, knocking both villains out.
*** The scene nicely resembles the cover to [[http://www.wtv-zone.com/silverager/flash/flash140.jpg ''Flash'' #140]].
** Eddie deserves mention as well, as he dives into the fight with nothing but one of Cisco's customized shields, saving Flash from a double attack by the villains.
* TheStinger. Both Captain Cold and Heat Wave are on their way to Iron Heights in a police wagon. Heat Wave is ranting about how Cold's obsession with the Flash cost them everything, but Cold is his usual calm and collected self, saying their current situation just means the plan changes. Then an explosion goes off (or some sort of commotion) and someone opens the police wagon door. Who opens it? Cold's ''sister''. The man has a plan for '''everything'''.

[[folder: Episode 11: The Sound and The Fury]]
* Hartley nearly kills Eobard Thawne. Not bad, for the 'Prodigal Child'.
* Hartley destroying the company of his parents who disowned him for being gay (old money, old values).
* Eobard saves Barry by sending a frequency through the satellite radios of all the nearby cars that destroys Hartley's special gloves.
** And at the beginning of the episode, where he directed Barry to steer 3 motorcycle crooks right toward each other.

[[folder: Episode 12: Crazy For You]]
* Barry being a [[{{Series/Glee}} great singer]] at the Karaoke bar. It helps when Barry impressed a girl enough that she gives him her phone number.
* While confronting Peekaboo, Barry hears a gunshot from behind and catches a bullet fired by Clay just before it enters the back of his neck. It barely broke the skin.
* Cisco and Hartley's fight. For a couple of nerds, they throw it down ''pretty hard''. And when Hartley almost escapes, Cisco whips out a vibration device of his own making that makes his hearing aids emit a sonic tone right into his brain.
** Hartley's eventual escape is also a villainous awesome moment, with him turning ''this'' against Cisco, allowing him to disable him using the same method. The icing on the cake? He did it ''after'' telling him what he wanted, and thus, lived up his end of the bargain, and made sure Cisco held up ''his''.
* Iris being fast enough with her phone's camera to get a picture of the Flash's face.
* Barry and Peekaboo both showing great creativity in their fights to constantly turn the tables on each other with their particularly well-matched powers.
* Though he doesn't outright say it, Henry figuring out that Barry is the Flash.
* Barry finds out his father's been stabbed by the underling of a local crime lord. He proceeds to take the assailant out of prison, and instead of attacking him, interrogates the thug on the activities of his gang. They finish their "interview" with the Flash leaving the thug outside of prison instead of returning him inside (police sirens can be heard closing in so he wouldn't even think of escaping on his own), adding 5-10 years to the thug's sentence. The Flash had his revenge without even getting too violent.
* The final scene where Grodd makes his debut, and it was tense, a little scary and definitely FREAKIN' AWESOME!

[[folder: Episode 13: The Nuclear Man]]
* Barry redeemed himself in Linda's eyes by eating a ghost pepper, which is the spiciest of all peppers (it is so spicy that it has been known to send people who try eating it to the hospital), thus becoming her "Spicy Champion" and winning back his date.
* Barry ''outrunning a nuclear explosion''
** Which is in itself a [[MythologyGag Mythology Gag]] to an issue where the Flash did the exact same thing, but saving ''all the people'' of the town being blown up.

[[folder: Episode 14: Fallout]]
* You have to admire the tenacity Professor Martin Stein shows when he refuses to give the military information about how F.I.R.E.S.T.O.R.M works. The professor didn't surrender even when he's shivering in the cold torture room and getting electro-shocked by a cattle prod. Even General Eiling is genuinely impressed by the professor's endurance.
* To contact Martin, Ronnie willingly cuts himself to write a message in his own skin.
** And in return, Martin taps his arm against a metal surface, using Morse code so Ronnie can relay the location.
* Ronnie and Martin are cornered by the military, leaving them no choice but to merge together again in order to fight back. This time, they performed a successful FusionDance due to cooperating with each other, resulting in Ronnie's body powered by Firestorm and Martin's sharp mind.
** Because they discussed the possibility of the merging being permanent, the FusionDance is treated as a GodzillaThreshold. And both Ronnie and the professor still decide to go through with it.
* The final scene. It features [[[DramaticUnmask our first look at the Reverse-Flash's suit]], our first full view of ([[EvilSoundsDeep and dialogue from]]) Gorilla Grodd, and the delicious karma of the episode's absolutely ruthless villain, all rolled into one.
** It's even better if you're a fan of the Franchise/{{DCAU}}, where Grodd was killed by Lex Luthor, voiced by Clancy Brown, but not before swearing he would somehow get revenge. It fits so perfectly that one wonders if this was done specifically to pay that moment off.
* Victorious over Eiling, we are treated to the Flash and Firestorm racing together back towards Central City. It makes fans think a live-action Justice League may just happen yet.

[[folder: Episode 15: Out of Time]]
* Captain Singh defended Joe from a lightning strike by Mardon. Singh may be suffering from paralysis and brain damage from his heroic action, but it was a quite the BadassNormal moment.
* A villainous one for Eobard Thawne. How he reveals himself to Cisco is a truly chilling scene. The way he explains everything; what his motivations are; even killing Cisco are all done in a chillingly calm and matter-of-fact manner. Not once did he raise his voice.
* The BigDamnKiss Barry shares with Iris, after she confesses she has feelings for him as well before he goes off to save her father, that leads directly into the reveal, as he immediately, and by immediate super speedy, changes into the Flash. The look on her face is priceless, both Shock and Awe!
* Barry Allen out-races a lightning bolt. He's in a car with doors closed and seatbelt on, the lightning bolt has already smashed through the sunroof, and Barry unbuckles his seatbelt, grabs Joe, unbuckles him, opens the door and quickly moves himself and Joe out of the car '''[[SlowMotion while the lightning bolt is moving in super-slow motion]]'''. From a sitting position, Barry saved himself and Joe from a lightning bolt that was literally three feet away from blowing up the car.
** He tops it at the end of the episode, when he runs so fast that not only does he create a wall of air to stop a tsunami from crashing into Central City, but [[BeyondTheImpossible he breaks the time barrier]] and winds up one day in the past.
*** This carries into a meta level by being such a big moment that for the first time they don't even try to top it with any kind of stinger.

[[folder:Episode 16: Rogue Time]]
* Both Barry and Cold have their respective BadassBoast on how much leverage they have on each other. Barry having his SuperSpeed to put Captain Cold away for life, but at the risk of revealing his true identity. It ends on a draw resulting Cold having no actual means to broadcast the identity of the Flash, but still free to go.
** Cold is perfectly capable of broadcasting the identity of the Flash if he wants to. It's just that if he does so, Flash no longer has any incentive not to capture him and turn him in to police.
* Captain Cold and Heatwave don't need their guns to send a message to a mob family. They simply kick asses after freeing themselves from being held captive.
* Reverse Flash decides to pay a visit to the reporter investigating Thawne and his connection to Stagg. The meeting ends with his hand through the reporter's chest.

[[folder:Episode 17: Tricksters]]
* The opening of the episode was a MomentOfAwesome! We finally get to see the fight between Reverse Flash and Flash in the Allen home, as they run around on walls faster than light. Giving us a glimpse into Barry's true potential.
** One highlight is Flash flinging the Reverse Flash into a wall and stomping on his chest.
* James Jesse's BatmanGambit. Arrange for a lost soul to act like a copycat, and then pretend to be enraged that somebody's stolen your act. Then have that copycat dupe the police to look for a bomb in the city, when the real bomb is at Iron Heights ready to go off to set you free. Also doubles as [[Heartwarming/TheFlash2014 Heartwarming]] when [[EvenEvilHasLovedOnes you know that said lost soul is in fact your long-lost son]].
* Jesse's "perfect trick": Infiltrate a fundrasing gala hosted by the mayor by posing as a waiter. He spikes the complimentary champagne with mercury poison that takes one hour to kick in, and effectively hold the entire poisoned gala hostage. He forces the guests to transfer all their funds into his bank account (the number is located at the bottom of the wine glass) before he gives them the antidote, and he has a gun with him in case they try to call 911.
** And he tops that by planting a kinetic bomb on Barry that will blow up if he goes below 600 mph or tries to take it off.
--> '''Trickster:''' Ooh, it's active. Run, run, run, run, run!
* Thawne coaching Barry on how tap into the Speed Force by telling him to vibrate at the same frequency as air. The result leads to Barry running through a truck and getting rid of the bomb bracelet on his arm:
--> Breathe. Feel the air. Feel that wind on your face. Feel the ground, your feet lifting you up, pushing you forward, and the lightning... Barry, feel the lightning. Feel its power. Its electricity pumping through your veins, crackling through you, traveling to every nerve in your body, like a shock. You're no longer you now. You're part of something greater. You're part of a speed-force. It's yours. Now do it.
** Considering that the bomb will go off if he runs below 600 miles/hour or forcibly take it off, it's a relief that Barry didn't have to run forever to prevent the explosion.
** The end of the episode: Barry figuring out from said coaching that "Wells" is in fact the Reverse-Flash.

[[folder:Episode 18: All-Star Team Up]]
* Another crossover episode with {{Series/Arrow}} is expected to be chock full of awesome moments:
* Barry manages to revive Cisco with his super vibration as substitute for a defibrillator.
* Felicity outhacks the Bug-Eyed Bandit and proceeds to drop the entire swarm dead on its tracks.
-->'''Felicity''': Stay away from Barry Allen!
* Ray manages to outmaneuver the swarm of robotic bees in his Atom suit and short circuited them.
** Despite frying his Atom suit in the process, Ray manages to safely land inside of Cisco and Caitlin's van.

[[folder:Episode 19: Who Is Harrison Wells?]]
* Once he stops holding the IdiotBall, Barry gets it together and gives the Shapeshifter the very definition of a SpeedBlitz. Even when the shapeshifter changes into Flash himself, Barry still outfights him!
* Thawne nonchalantly taking down Barry!Bates with a tazer before the shape shifter can attack Caitlin and Iris.
* At Laurel's request, Cisco invents '''The''' [[MakeMeWannaShout Canary Cry]]. He repurposes (and improves on) Sara's sonic devices, fits it into a choker that won't look out of place on her costume, ''and'' does it in whatever spare time he has on his visit to Starling City.

[[folder:Episode 20: The Trap]]
* Barry saves the people (including Captain Singh's fiance) trapped in the fiery building by creating a vacuum from his super speed arm rotation, therefore putting out the fire in a flash.
* It turns out Eobard has been keeping tabs on the team and has known about their growing suspicions of him the whole time, culminating in his sending Hannibal Bates disguised as him into the trap they prepared while he heads out to kidnap Eddie.
** Even though it was somewhat a disappointing outcome for the team, the fact that Joe killed Hannibal Bates with a precise heart shot goes to show his excellent marksmanship.
** In that same moment Barry manages to run after and snatch harmlessly out of the air 2 out of 3 bullets. It really shows how fast he's become since the beginning. And hell, the ''only'' reason he didn't catch the third is because of the force field bouncing him back!
* After a whole season of keeping Iris LockedOutOfTheLoop, she ultimately doesn't need anyone to tell her and figures it out through her own detective work plus a handy EurekaMoment.
* The implication that the Arrowverse is heading towards making its own Justice League, particularly given how the DCCinematicUniverse has been screwing with the shows and dictating which characters they can use.

[[folder:Episode 21: Grodd Lives]]
* Following up on her learning Barry was the Flash last episode, Iris wastes ''no time'' revealing this: literally, Iris arriving at S.T.A.R. Labs to reveal she knows happens five minutes in.
** This leads to Iris giving her dad a '''WELL''' deserved WhatTheHellHero moment, for not only not telling her about the incident, but on the stupidity of not telling her about Flash. She then explains that she could have helped, could have stopped putting herself in trouble, and even stop writing the blogs about the Flash.
** Also, just how quickly Iris fell into the groove at S.T.A.R. Labs, and, in a part Awesome part [[Heartwarming/TheFlash Heartwarming]] scene, in which Cisco and Caitlin are in a panic, Iris calmly and knowingly snaps Barry out of his Grodd induced Mental Stupor with just the sound of her voice.
-->'''Iris''': ''Barry'', Do it for me!
* ''Everything'' about Grodd. For starters he pulls a NoSell when Barry tries to do his super sonic punch.
** Not to mention that Grodd has come so close to killing the Flash with his MindRape telepathy. If Iris didn't snap Barry out of his senses, he would have been squashed by a subway train while under Grodd's trance.
** Turns out Grodd survived getting hit by a subway train and proceeds to climb up a building King Kong style before TheStinger begins.
* A double header for Eobard: 1) he's hiding with Eddie underneath STAR Labs where nobody would think to look and 2) He turned the particle accelerator into a giant Cosmic Treadmill.

[[folder:Episode 22: Rogue Air]]
* [[DamselOutOfDistress Iris]] [[ActionSurvivor West]] rescuing a cornered Caitlin's life by knocking an escaped Peek-a-Boo out cold from behind mid-taunt.
* Considering how long Eddie endured captivity from Thawne, it's still commendable of him to have enough energy shouting out for help so that Team Flash can hear and rescue him.
* On the dark side, we have Snart double crossing Barry and releasing all of the captured metahumans back out into Central City]]. And this is after talking Barry into destroying all federal evidence of his existence.
* Snart also shows remarkable NervesOfSteel as he stares down both Weather Wizard and Prism after casually murdering Deathbolt. It helps that he has his sister backing him up.
** Which in turn also leads to Lisa's awesome moment as she casually puts her gold gun to Bivolo's head when he tries using his HatePlague powers on Leonard and tells him to "Power down if you don't want me to melt your face".
* The all out 3 on 1 battle between the [[BigBad Reverse Flash]] and a team consisting of the Flash, the Arrow and Firestorm. And thus we have the genesis of the ArrowVerse's version of the Justice League.
** And while Ray couldn't make it to the fight, his nanites are what let them negate Eobard's powers and take him down.
** Reverse Flash managed to hold his own against three of his opponents, taking down both the Flash and Firestorm temporarily. While Arrow is the only non-metahuman of the group, he managed to fight on par with Reverse Flash (albeit disabled super speed) while Firestorm was recovering from being blown away and Flash busy helping out Firestorm.
** What makes it more awesome is that Reverse Flash is holding his own in a melee fight against Ollie post-training with Ra's.

[[folder:Episode 23: Fast Enough]]
* The implication that Cisco has been affected by the Particle Accelerator and that one day he may become Vibe. And on the evil side Caitlin may become Killer Frost.
* The HeroicSacrifice that Eddie makes erases the existence of Eobard Thawne just before Barry is about to get killed.
** Seeing the monstrous Eobard Thawne ''finally'' getting what he deserved is quite [[CatharsisFactor cathartic]].
* Barry running right into the middle of a Black Hole to prevent a universal calamity
** And from what we see, it's not having any effect on him. Translation? Barry is outrunning a ''black hole''.
* Barry's RoaringRampageOfRevenge after witnessing his mother die once more. Sadly, [[CurbStompBattle it doesn't get far]], and seems to only make things worse.
** On that note: the final fight between Barry and Eobard, while awesome in and of itself, is one for Eobard. He shows Barry that, no matter how fast or strong he gets, Eobard will always be one step ahead.
* As Eobard prepares to go through the wormhole, a silver winged helmet flies through, which [[OhCrap he takes as his cue to leave]]. It seems that Barry isn't the only Flash Thawne has made an enemy of. In fact, he's quite scared when he sees the helmet; as we see in Season 2, he's right to be.

!Season Two
[[folder:Episode 1: The Man Who Saved Central City]]
* The Flash finally getting recognition for being the saviour of Central City 6 months after the singularity incident. It's nice to see that civilians show their appreciation towards their icon of hope despite all of the hardships that had to suffer since the particle accelerator explosion.
* Joe [[ImprobableAimingSkills bullseyes a pair of propane tanks in mid-air]] after Barry throws them at Atom Smasher in their first confrontation.
* Just how quickly Stein and Iris fell in as official members of Team Flash.
* The addition of the Iconic White Circle to the Lightning Bolt insignia on The Flash's suit.
--> '''Stein''': Well see I like it. The lightning definitely pops more against the white.
* Barry shows he's mastered those late Season One tricks, like the classic Flash ability of vibrating his body's atoms to move through solid matter, and creating tornadoes that even Atom Smasher has trouble with.

[[folder:Episode 2: Flash of Two Worlds]]
* An OffscreenMomentOfAwesome, but with the revelation that "Jay" has inexplicably lost his speed makes his casual stroll into S.T.A.R. Labs, with recently beefed-up security, an impressive example of either strength, wit, stealth, or a combination of the three.
* Dr. Stein and Cisco proving the existence of alternate universes and discovering the gateways to these universes. A minor scene in the show, but if this news ever broke out, they'd win the Nobel Prize of the millennium.
* "Jay Garrick" coaching Barry how to throw a lightning punch at Sand Demon is pretty awesome considering how Barry didn't trust "Jay" earlier in the episode. The cherry on top of this moment is when Barry pulled it off and turned Sand Demon into shattered glass.
* Cisco tapping into his Vibe powers to figure out where Patty is kidnapped and what kind of trap Sand Demon laid when nobody else has a clue on where to find her.
* Patty's hard work and determination finally landed her a spot in Joe's Anti-Metahuman Task Force. It helps that her school credentials are the best among her class.
* The recreation of the iconic Flash of Two Worlds comic cover.

[[folder: Episode 3: Family of Rogues]]
* Barry catching Iris in Mid-Air after telling her to jump out a window to flee her pursuers.
** Even more so, Barry ''literally'' dropping what he's doing when he hear gunfire on the other side of the phone, and arriving in Uniform, that means he raced from his lab at the CCPD, to S.T.A.R.S Lab to change into his Suit, then rushed across Central City again to catch Iris mere seconds after she jumped. Yeah, he's the Fastest Man Alive, but still, ''Wow!''
** Followed with him immediately racing back to the top of the building and incapacitating all of Iris' attackers while alerting the CCPD to their location.
* Barry being fast enough to catch a bullet and make Snart and his dad think he's dead.
* Cisco removing the explosives from Lisa's head.
* Cold finally giving his dad the karma he deserves by killing him with his cold gun.
--> '''Lewis''': [[EnemyMine You're working with the Flash... I thought you hated him.]]
--> '''Leonard''': [[PreMortemOneLiner Not as much as I...]] ''[[PreMortemOneLiner hate]]'' [[PreMortemOneLiner you.]]
* On a meta-level, the show refusing to copy last season's shtick of keeping Iris LockedOutOfTheLoop. The length of secret keeping from her has gone from most of a season to half an episode.

[[folder:Episode 4: The Fury of Firestorm]]
* The flashback from the Particle Acceleration Explosion shows how Jax saved a high school boy in crutches by getting him to safety within the stadium. Jax may have taken the explosion's impact, but his selfless heroics is what allows him to become a worthy half of Firestorm.
** Before the explosion, Jax has his teammates and coach congratulating him for making a game-winning touchdown for the football match. It makes it even more awesome when the coach mentions that there are spectating university recruiters on their phones considering about giving Jax a football scholarship.
* The [[UnexpectedCharacter sudden appearance]] of [[ComicBook/SecretSix King Shark]] at the end, in addition to being scary, is awesome for how it was [[BrickJoke humorously]] [[{{Foreshadowing}} foreshadowed]] earlier in the episode and for [[SugarWiki/VisualEffectsOfAwesome how splendidly rendered he is]].
** Patty shows her courage by pulling her gun on the huge monster and emptying it into him (even if he does NoSell [[ImmuneToBullets the bullets]]) to save the Flash. A moment later, Harrison Wells of Earth-2 tops it off in true BigDamnHeroes style by zapping King Shark in the back and knocking him out with an energy weapon, thus [[InternalReveal revealing himself to Barry]].

[[folder: Episode 5: The Darkness and the Light]]
* Barry successfully creates speed mirages to confuse Dr. Light courtesy of both "Jay" and Earth-2 Wells coaching.
* Cisco finally lands a date with Kendra thanks to Barry's encouragement in getting her phone number. Considering how awkward their first encounter was, it's reassuring to see that Kendra didn't tell Cisco to buzz off.
* Now that he's accepted his powers, Team Flash realizes that Cisco needs an alias. Barry suggests, "Vibe?" Caitlin tests it herself, then Cisco smiles the grin of an AscendedFanboy and agrees, "Vibe!" The whole scene gives you chills.
* Iris shooting Dr. Light's helmet right off of her head.

[[folder: Episode 6: Enter Zoom]]
* Doctor Light escaping the pipeline through clever usage of her powers.
* The whole Zoom-Flash fight. Barry is, as Cisco notes, not afraid, and does his best to fight Zoom, its just not enough. Zoom catches Barry's lightning attack and throws it right back at him! Barry then concludes that he needs to even the odds so he gets Zoom to chase him off a building, so their speed is equal as they are in free-fall. Zoom wins, but its not for lack of trying on Barry's part-and Zoom's own efforts are as awesome as they are horrifying-catching a half dozen cop's pistol fire with one hand effortlessly, and racing from the newspaper to the police station and back to Star Labs in instants.
** The whole sequence deserves some kind of award. The sense of speed and power in every frame is incredible. It's easily the most impressive fight in the series to date.
* Just as Zoom is about to kill Barry in front of all his friends at STAR Labs, Cisco of all people gets the drop on him and shoots him while he's busy monologuing, driving him to flee and probably saving Barry's life.

[[folder: Episode 7: Gorilla Warfare]]
* Near the end of the episode, Barry regained his confidence in his speed by taking down Grodd into a breach. If you remember last season, Grodd can easily catch Barry's supersonic punch without much effort.
* Keep in mind that Grodd was stubbornly holding on with all his might in order to not get sucked into the breach for a few minutes. That takes significant strength to not get sucked into the breach.
* Harry facing Grodd to rescue Caitlin was very impressive as well.
* Cisco's vibe of Hawkgirl looks ''amazing''.

[[folder: Episode 8: Legends Of Today]]
* Kendra getting her wings and taking flight for the first time
* The fight between Hawkman, Flash and Green Arrow.
* Vandal Savage fully proves himself worthy of being the BigBad of a whole new show when he throws knives at Barry's allies, forcing him into a straight path to grab them, and then managing to fire off another one to nail Barry with perfect timing ''while'' he was at super speed.
* Despite hating Harrison Wells, "Jay" reluctantly took the Velocity-6 drug to enhance his speed temporarily in order to remove a bullet from Wells quick enough without damaging the pulmonary artery.
* Oliver casually disarming Damian Darhk's minions at the beginning of their fight:
-->'''Darhk:''' You brought arrows to a gun fight?\\
'''Oliver:''' [[PreAssKickingOneLiner What guns?]] ''(activates a magnetic arrow, pulling away all the guns)''

[[folder: Episode 9: Running to Stand Still]]
* Barry using a ''running helicopter blade'' as a launch pad to catch up to the flying Mardon.
** Most likely just as impressive is that he's zooming across buildings.
* Mardon and Trickster use a SadisticChoice in the form of bombs hidden as presents distributed to random children throughout the city to force the Flash to let them kill him. Wells comes up with the idea of using one of the breaches to get rid of all the bombs at once. The Trickster is just about kill Barry with a knife when Cisco informs him they've lost their leverage, upon which lightning crackles in his eyes and Trickster has a ''glorious'' OhCrap moment when he sees it.
* Both Barry and Mardon have learned to use [[BlowYouAway their powers]] to fly.
* Iris gives a pretty awesome ShutUpHannibal to Captain Cold:
-->'''Cold:''' "Didn't you hear? I had a rough childhood."
-->'''Iris:''' "Everyone in this room had a rough childhood. Get over it!"

[[folder: Episode 10: Potential Energy]]
* With Cisco unable to neutralize the Turtle's powers, Barry simply uses brute force, getting enough of a running start that he can push through the entropy waves and punch the Turtle hard enough to send him flying.
* TheStinger, where [[MagnificentBastard Eobard]] [[EvilIsCool Thawne]] makes his grand return, ''[[BeyondTheImpossible despite having been erased from existence]]''.

[[folder: Episode 11: The Reverse-Flash Returns]]
* A moment years in the making for Barry: he ''finally'' defeats the Reverse-Flash on his own. Even more impressive he doesn't do it by being faster, he does it by being ''smarter''.
** Not only that but a personal character moment for Barry: he is so utterly [[CurbStompBattle curb-stomping the Reverse-Flash that you wonder for a second whether it will play out like the comics, and the Flash will ''[[NeckSnap kill the Reverse-Flash]]''. Fortunately, he manages to resist and settles for imprisoning him.]]
** Barry wins because he's able to find a shortcut to cut off Thawne. All of that good Samaritan work paid off. Barry protects his city. He knows his city.
* Just like Iris, Patty ultimately doesn't need anyone to tell her Barry is the Flash. And she didn't even need a coincidental blatant clue like Iris got, and figures it out through good old detective work.
* Cisco speaking to Eobard Thawne in his prison cell gives us this awesome exchange:
-->'''Cisco''': I want you to know that I'm the one who figured out you were back. I helped stop you. Me.
-->'''Eobard''': And how'd you do that?
-->'''Cisco''': I have powers. And I helped track you down and I put you in here.
-->'''Eobard''': That's quite the ability you've been given.
-->'''Cisco''': [[HoistByHisOwnPetard And here's what's so ironic about it. You gave me these powers. Have fun thinking about that while you rot away in this cell that you helped me build.]]

[[folder: Episode 12: Fast Lane]]
* Joe gets two PapaWolf scenes in quick succession. After discovering that Wells has been stealing Barry's speedforce, he punches him out, grabs him, and throws him in a cell, saying it's either that or he'll shoot him. Not long after, he does the same thing to Tar-Pit after the metahuman put Iris in the hospital.
* Barry and Harry closing a breach with the Breach Implosion Reactor, and in essence rewriting the laws of physics. Barry is ecstatic that it worked and even Harry has to admit that it was pretty cool.
* Iris' entire reaction to Wally's drag-racing. Not only does she call out Joe for trying to be his friend instead of his father, she uses her investigative skills to find out everything she can about the guy running them, before threatening him with exposure and then arrest. Especially awesome because she's clearly scared out of her mind and didn't even call Barry for backup, but she did it anyway because that's how much she cares about Wally. Plus, it's nice that we get to see her as a badass reporter.
--> '''Wally''': Do you have a death wish?
--> '''Iris''': You're not the first person to ask me that, so maybe.

[[folder:Episode 13: Welcome to [=Earth-2=]]]
* The trip through dimensions, featuring glimpses of [[Series/TheFlash1990 a different Barry]], [[Series/{{LegendsOfTomorrow}} a different Green Arrow]], the ComicBook/LegionOfSuperHeroes, ComicBook/JonahHex, and '''Series/{{Supergirl}}'''. Yeah, this crossover is officially happening.
* Reverb, the Earth-2 version of Cisco, is a serious badass who can not only see things from other Earths, but can generate powerful vibrations and attack people with them. If this is an indication of the power that Cisco will one day achieve, then Earth-1's metahumans have a lot more to worry about than just The Flash.
* The Arrowverse crew gives their biggest middle finger yet to the ExecutiveMeddling from the Franchise/DCExtendedUniverse, with an appearance from Earth-2 Deadshot and the implication that Earth-2 Barry has Batman, Green Lantern, and Wonder Woman on his speed dial.
* After learning the truth about Velocity-6, Caitlin is able to make a safer version in just a few hours. This allows "Jay" to show some of what he can really do as the Flash, including using his helmet for a directed vibration attack.

[[folder:Episode 14: Escape from [=Earth-2=]]]
* In the opening, instead of Barry narrating, it's Zoom! He proceeds to cause the city to burn, even making words of flames appear on buildings to declare he wants Harrison Wells. This works so well that the police are willing to capture Wells. That's right: The police are willing to bow to Zoom so much, they will kidnap people for him!
* Earth-2 Barry has created an algorithm that tracks down metahumans with an impossibly complex array of statistics. Even without superpowers, he's a quite valuable crime fighter.
* Who captures Geomancer? Not [[EvilAllAlong "Jay"]], not [[ActionGirl Iris]], but [[ActionSurvivor Caitlin]]! [[BewareTheQuietOnes Girl]] proves that even without ice powers, she's a [[BadassNormal badass]]. Crosses into CrowningMomentOfFunny with this moment:
--> '''Iris''': Nice shot!
--> '''Caitlin''': I was aiming for his leg.
* Caitlin also deserves some credit for perfecting the Velocity-9 Formula. Not only does "Jay" get his speed stabilized, the damaged cells in his body are repairing themselves. Caitlin saved Central City in more ways than one.
* Barry and Jesse put their brains together and figure out what the mysterious masked man's tapping means. Barry knows it isn't Morse Code because the tapping uses a special 5x5 sequence that decodes 25 letters ("C" and "K" being the same in the pattern). Jesse also helps on decoding what the masked man's tapping is about: J-A-Y, as in Jay Garrick. Unfortunately, Zoom interrupts before they can find out the whole story.
* At one point Zoom enters Barry's cell. Barry, who was ''crippled'' the last time he fought Zoom, just defiantly says he going to destroy him prompting a beating from Zoom. After the villain leaves all Barry takes away is that he now has a way of escaping his cell. In a few words it becomes obvious that while Zoom is TheDreaded to everyone else, to Barry he's just another criminal to be taken down.
** This scene really stands out because Barry actually gets under Zoom's skin, a feat not even Eobard Thawne has pulled off with his defiance. The villain that wants all to fear him can't break the hero with hope.
* Earth-2 Barry's RousingSpeech that inspires our Barry to vibrate faster than ever before to get out of his cage.
** Or, in other words, Barry didn't believe in himself, [[Anime/TengenToppaGurrenLagann so he believed in the Barry who believed in Barry.]]
* Killer Frost having a full Darth Vader moment when Zoom's attempt to kill Jesse gets her to turn on him for good. She holds him back as the others escape, knowing full well that she can't keep it up for long and faces a very painful death when he gets out of it.
* Team Flash finally getting one over on Zoom: By episode's end, they've escaped Earth-2 with Jesse, meaning Zoom no longer has leverage over Harry. They also manage to seal the last remaining breach, so Zoom cannot travel back to Earth-1 (for the moment, anyway). Unfortunately, Zoom gets the last laugh when he kills what would be revealed to basically be himself.

[[folder:Episode 15: King Shark]]
* Just the fact that King Shark is back at all. He was originally only meant to be an impressive (and expensive) bit of CG work by the crew and a chance to show off how {{Badass}} Harry is. However positive fan reception has now {{Retconned}} his supposed death so that he can be [[MonsterOfTheWeek the villain of his own episode]]. And he still [[VisualEffectsOfAwesome looks as good as ever]].
* Joe West, seeing King Shark in his house, shoots at the nigh-invulnerable fish-man. It may not have done more than distract him, but given what this thing has done to government-trained agents, that takes a LOT of guts.
* Barry and King Shark's aquatic battle, which Barry wins by electrifying the water, finishing the beast off with a lightning throw.
* Although Barry helped out with Wally's school project, Wally was able to complete a biodiesel fueled turbine engine for his assignment all by himself. This goes to prove that Wally isn't so BookDumb.
* TheReveal in TheStinger of Zoom's face. In just thirty seconds and after fifteen episodes of buildup, the show throws a curveball that questions everything we thought we knew about "Jay Garrick".

[[folder:Episode 16: Trajectory]]
* Earlier in the episode, Barry couldn't run fast enough to jump across a canyon. It was only when Trajectory destroyed a bridge that he ran Mach 3.3 in order to jump across the bridge gap.

[[folder: Episode 17: Flash Back]]
* Barry managing to beat Eobard, so he can't kill him, by deliberately leaving a DeadManSwitch so if he killed him, it would ruin Thawne's plans. Thawne is pissed, but gives him what he needs to avoid that.

[[folder: Episode 18: Versus Zoom]]
* Seems that Eobard's formula worked. To Iris, Cisco and Caitlin's amazement, Barry's now 4x faster than he's ever been.
** Even more than his friends realize, Barry was moving fast enough [[Recap/Supergirl2015S1E18WorldsFinest to warp himself to another dimension]].
* Sure he's rather reluctant, and downright frightened to do so, but Cisco using his powers to reopen the breaches to Earth-2.
* Flash vs Zoom, Round Two:
** Barry shows, through his newly-improved speed and knowledge he gain on Zoom's past, how he is now more of a match for Hunter Zolomon... [[HopeSpot in a straight up speedster fight at least.]]
** But then Hunter shows [[GeniusBruiser how he is not lacking in the battle smarts department, holding Wally hostage to finally get Barry's speed.]]
** [[TheBadGuyWins So it's now 2-0.]]
** Regardless of how it ended, the simple fact that Zoom's SmugSuper expression got wiped off his face (even just for a few moments) when he realized that Barry figured out his true identity and used images of his parents against him was immensely satisfying.
* In a nightmarish way, the explanation for how Zoom and "Jay" could exist at the same time. They ''both'' were Hunter Zolomon all along; it's just that the one who was killed in front of their eyes was from an alternate timeline. Zoom's own Time Remnant, disturbing as it is, [[StuffedInTheFridge agreed to be murdered]] [[ThanatosGambit in order to traumatize Team Flash and get them to increase Barry's speed]].]]

[[folder:Episode 19: Back to Normal]]
* Caitlin coming face to face with Killer Frost.
* [[ActionGirl Iris']] instinctive reaction to grab the gun after witnessing Harry's accident site.
* [[TheHero Barry]] still going against Griffon, even without his powers.
* Jessie Wells joining TheTeam in the field, to save Harry.
* [[BigDamnVillains Zoom's]] [[CrowningMomentOfAwesome spectacular]] [[ImpaledWithExtremePrejudice rescue]] [[IntangibleMan of]] [[MadLove Caitlin]] [[SuperSpeed from]] Killer Frost.
** After Caitlin helps her escape from her cell, Frost double crosses her, believing (correctly) that now Zoom has the "real" Caitlin, he's got no reason to let Frost live. Frost drives Caitlin into the tunnel exit of Zoom's lair and launches an icicle at her...at which point Zoom comes flying down the hallway, [[CrowningMomentOfAwesome PHASES THROUGH]] Caitlin, [[ArrowCatch grabs the icicle mid-flight]] [[HoistByTheirOwnPetard and stabs Frost with it.]]
[[folder: Episode 20: Rupture]]
* Barry managing to use holograms of the Flash to fight crime and Rupture.
** Holograms allowed the Police to handle Rupture.
* Even though she is still at Zoom's mercy, Caitlin risking pretty much her own life to get a message to Joe and the CCPD about Rupture's attack.

[[folder:Epsiode 21: The Runaway Dinosaur]]
* Despite being mere minutes after she watched the man she loved ''die'' (or so she thought at the time), Iris goes full on BigSisterInstinct with Jessie and Wally after finding them unconscious alongside Joe and Harry.
* Barry literally having conversations with the Speed Force in the forms of his loved ones ''(Joe, Iris, Henry... and Nora)''.
-->'''Barry''': ...That's trippy.
* Barry chooses to stay and regain his powers, even when Cisco vibes and offers him the chance to return.
* [[ActionGirl Iris]] using herself as bait to lure Zombie Girder back to STAR Labs.
-->'''Joe''': Are you sure about this?
-->'''Iris''': [[DidntThinkThisThrough You know what, two minutes ago, I would have said yes, absolutely.]] But now, ''What the Hell!?!''
* Barry finally regaining his powers!
* Barry bringing Jessie out of her coma by just touching her hand.
* So Zoom has a small army of metahumans working for him. That alone has a lot of potential for Awesome, although it looks like they're mostly fairly normal people with a variety of weapons or small powers... wait, is that Atomic Skull?

[[folder: Episode 22: Invincible]]
* The leader of Zoom's army is Black Siren aka the Earth-2 Laurel Lance.
* Team Flash taking out Zoom's metahuman army by remembering that everyone on Earth-2 vibrates on a different frequency and using that against them by creating a sonic weapon to take them out ''all'' at once Zoom of course is fast enough to create a breach to Earth-2 but even he was in pain for a moment.
** Combined with HeartWarming, Harry gives Jesse his earphones, the only thing that protects him from the sonic weapon's effects, when her own fail to block the frequency.
* Early in the episode, Barry captures several metahumans at once, all by himself.
* Wally using CarFu to rescue Barry from Black Siren.
* Cisco and Caitlin pulling off flawless impersonations of Reverb and Killer Frost. Yes, Black Siren sees through it, but for a moment you'd swear that the two supervillains had returned.
** Not to mention she could have easily hurt or even killed them, but they lost their cool only when the Black Siren saw through their act. Considering how they've reacted when faced with less dangerous metahumans, gotta give them props for walking into the lion's den.

[[folder: Episode 23: The Race of His Life]]
* How Barry finally stops Zoom: he creates a time remnant of himself during the booting up of the Magnetor. Barry frees Joe while the time remnant keeps Zoom busy; then, while Barry and Zoom are fighting, the remnant creates a force strong enough to stop the Magnetor, [[HeroicSacrifice sacrificing himself in the process]] -- as well as luring out the Time Wraiths to destroy Zoom.
** The actual final fight between them: Barry ''pounds'' Zoom. After seeing Zoom's actions the entire season, his time as BigBad ending with the Flash utterly pounding him then leaving him to his demise is satisfying to say the least.
** The MythologyGag of Zoom turning into the Black Flash, complete with the red and white ChestInsignia, as the Time Wraiths attack him and drag him off is wonderfully creepy.
** This time, on his own, Barry just proves he is "The Fastest Man Alive"!
* The identity of the Man in the Mask: Henry Allen's doppelganger from a third Earth, who is also the ''real'' Jay Garrick. Getting to see John Wesley Shipp in a Flash suit again is the perfect capper.
** Jay declaring he never wants to see the mask again and ''slicing it in half'' with a vibrating hand.
* While it obviously will cause no ''end'' of problems with the timeline, there's an undeniable vindictive satisfaction in seeing Barry go back in time and save Nora by delivering a CurbStompBattle to the Reverse-Flash, ending it by knocking the murdering bastard out cold. The stunned gape on Eobard's blurred face and the surprised smile that the Season One Barry gives just before fading from view really sell it.

! Meta
[[folder:Meta (human)]]
* Unlike ''Series/{{Arrow}}'', which tries to be much more grounded, this show's heavy use of metahumans means it's much more effects-heavy (Barry's speed effects, Mardon's tornado, and Nimbus's mist effects just from the first two episodes, for starters.) And as shown throughout the entire first season, [[VisualEffectsOfAwesome they've handled it really well]].
* The fact that they've tackled Gorilla Grodd, one of the more outlandish elements of the Flash mythos, in live-action.
** And King Shark. And made you believe that a 15 foot tall shark man could...um...swim.
* Many queer viewers have been praising the fact that Captain Singh is gay, like his comic book counterpart, and especially the fact that his statement confirming this was ''the'' most casual and normalized thing he could have said.
--> "My boyfriend wants us to eat more healthy at home, so this is the only place I can eat what I ''like.'' Sorry, you were saying something?"
** Later in the season, he just as casually reveals that he and his boyfriend are now engaged, and no one treats him any differently.
* Creator/MarkHamill reprised his role of the Trickster, having played the role both in the 1990's TV show and in ''Justice League Unlimited''. The sheer amount of ActorAllusion going on here is simply glorious, culminating in one beautiful line: [[spoiler: "I am your father."]]
* The CW releasing a teaser not for an episode, but for a ''villain'' - Grodd, a few weeks before he fully revealed himself to Team Flash. It's a warning: '''Grodd is Coming'''. It's a testament to just how popular Grodd has become among viewers and fans even though he'd only had a few minutes of screen time before his debut. [[https://www.youtube.com/watch?v=cGA0fxXBwc0 Watch it here.]]
** And on a side note General Eiling, looks ''terrified'' in the teaser. Keep in mind Eiling is a man who thinks he can bully meta-humans to be living weapons, and Grodd is able to scare the hell out of him.
* Not directly Flash related, but Jesse L. Martin, Carlos Valdes and Rick Cosnett took part in a Kickstarter project titled "The Letter Carrier". This Kickstarter [[https://twitter.com/josswhedon/status/580256287100792832 got the support]] of none other than '''Creator/JossWhedon'''. [[https://www.youtube.com/watch?v=Ac3a49-sj3A This]] was how the three thanked Whedon for his support.
* Superhero Fight Club. Black Canary and Arsenal fight Merlyn. Arrow fights Ra's al Ghul. Flash takes on Captain Cold and Heatwave, then the Reverse-Flash. [[https://www.youtube.com/watch?v=p1P7ujKw9yQ It's as awesome as it sounds.]]
* By stopping the singularity, 52 breaches in Earth-1 materialized. By doing this, the CW has just made its own version of ComicBook/TheNew52!!
