* Season 1, Episode 9: When teleporter Kuroko fights a thug, whose power make her own useless. Her response: [[spoiler: Lure him into an abandoned building and [[DroppedABridgeOnHim let it collapse about both of them]]! By [[TeleFrag cutting the support columns with glass plates]]!]]
* In the climax of the Level Upper arc, [[spoiler: Mikoto battles a creature formed from the AIM Dispersion fields of ten thousand individuals, which Kiyama dubs "AIM Burst". After the AIM Burst loses its HealingFactor, she proceeds to cut loose and use her full power, releasing a blast of electricity so intense that, even though the creature blocks it with a barrier, the heat generated from all of the electricity is still more than enough to ''completely burn its skin off and roast it alive''. Then she uses magnetized iron sand to block whatever attacks it throws at her, ripping multiple limbs apart in the process, then finishes it off with her [[SignatureMove Railgun]].]]
** [[https://www.youtube.com/watch?v=OXkbQoXNusc You can see it here!]]
* ''Every single time'' [[BadassNormal Wataru Kurozuma]] kicks ass.
* Season 1, Episode 23: Mikoto is outnumbered and outmatched by a company of PowerArmor mooks. [[spoiler: [[BigDamnHeroes Kongo arrives]]]] and gives them a single warning to withdraw. [[OffscreenMomentOfAwesome In the time it takes to cut to the next scene]], the BigBad learns that the [[CurbStompBattle entire company has been wiped out]] by their new opponent.
* In Episode 24 of Season 1, [[spoiler:Mikoto takes down a HumongousMecha piloted by Telestina by latching onto its RocketPunch, ripping the projectile to pieces, and then with Kuroko's help, using a large chunk of debris as ammo for a ''huge'' Railgun.]]
* Saten gets her moment [[spoiler:near the end of Episode 24 when she saves Mikoto and the others by smashing Telestina's [[PowerNullifier Capacity Down]] machine with a baseball bat.]]
** [[spoiler: And just to add to her moment of awesomeness, she delivers a short but sweet Shut up Hannibal to the villains endless ranting about regarding the whole city as her guinea pigs. "Guinea pig or not, I don' really give a damn! You keep your hands off of my friends!" SMASH.]]
* During the first Railgun SS, Mikoto [[spoiler: takes Flight using her power and all but destroys the magicians' ships to protect Liberal Arts City before the lifeboats could escape.]]
* Mikoto's BigDamnHeroes moments saving [[spoiler: Lessar in the second Railgun SS.]]
* Episode 1 of Railgun S:
** Mikoto stops a helicopter from taking off by pinning it down with magnetism.
** Saten catches Erii when the thugs throw her out of the helicopter, nearly dislocating her arm in the process.
** Kuroko teleports Mikoto several times in a row so she can catch up to the helicopter. Mikoto destroys it with her railgun upside down while falling from the sky. Kuroko teleports all the thugs to the ground.
* Episode 2 of Railgun S: We find out that [[spoiler: Shinobu]] is the one placing cash cards in alleyways and is eventually confronted by a gang of Skill Out thugs who are trying to rob her. With only a dramatic performance, two vials of local anesthesia and some improvised props, she bluffs them into thinking that she has a deadly esper ability that allows her to kill anyone she has ever touched with a thought, and frightens them into leaving her alone.
* The end credits of Episode 5 of Railgun S may count as CrowningMusicOfAwesome.
* Misaka's entire fight against ITEM on August 19th, but special bonus points for outsmarting the [[FrickinLaserBeams Meltdowner]] by using her [[StuffBlowingUp bomb happy]] companion's own traps against her twice when the constant battles had worn her down.
* Railgun S Episode 15-16: Touma vs Accelerator. Though this was already shown in Index season 1, the battle here is much more beautiful. After the latter has been driving Misaka to despair through the Level 6 Shift experiments and boasting of his near-infinite power, Touma decides to take on the strongest Level 5 by himself. Accelerator goes a final double-handed strike... only to receive the mother of all punches is laid out on his backside in the gravel. Cue freak-out, and a desperate attack, followed [[http://www.mangareader.net/1080-58418-30/to-aru-kagaku-no-choudenjibou/chapter-36.html by]] [[http://www.mangareader.net/1080-58418-31/to-aru-kagaku-no-choudenjibou/chapter-36.html this]]. This continue on for a few moments with Touma having the upper hand until Accelerator begin to gather the plasma ball.
** After the Sisters had halt Accelerator's attempt to form the plasma ball, a half-dead Touma stand back up, ready to end the fight. Accelerator is so frighten by Touma's determination that he unconsciously attempts to run away. Accelerator proceeds for the kill only for Touma to break his fingers and finish him off with one last punch.
* Mikoto's exploits in Episode 23 of Railgun S are impressive. [[spoiler: She got injected with something that shut off her voluntary nervous system, so she proceeds to use her electrical powers to emulate nerve signals, then goes to meet up with her friends who are raiding the warehouse she's held in because she implanted herself with a TrackingDevice in case she got captured.]]
* Most of the finale for Railgun S: [[spoiler: First with many Judgment members coming to help take down the armored suits, and using Kuroko's CatchPhrase, Mugino and the rest of ITEM lend a hand, Misaka does [[Franchise/MassEffect a vanguard charge]] to stop the BigBad from shooting himself, then Saten and Uiharu pilot a HumongousMecha made by Kongou Airlines, Mitsuko launches said HumongousMecha into space with her wind powers, and finally Misaka uses said HumongousMecha as ammo for a '''huge''' Railgun to take down a missile IN SPACE.]]
** Kuroko in particular deserves a special mention. [[spoiler: During the Silent Party attack, pretty much all of Judgment is focused on just drawing the powered suits' attention and keeping the 20,000 strong army contained. Cue Kuroko teleporting around like a madwoman, one shotting dozens of powered suits at a time with friggin' ''javelins''. After all, they're a threat to onee-sama, and robots are acceptable targets!]]
** Saten takes on the powered-suits with her baseball bat, until everyone's favorite Anti-Skill officer Yomikawa shows up with an even bigger powered suit, which Saten had spent the night before learning to pilot. She then proceeds to kick much robot butt.
** ITEM shows up, with Mugino furious that STUDY had sent them around on a number of pointless errands to analyze their abilities, AND copied her powers for their latest robots.
** Mikoto stopped the bullet from Arotomi Haruki's gun, but took some damage from it. What does she do? Slaps Arotomi with her wounded hand, leaving her blood on his face. She never once mentions the obvious pain she must be in.
* Chapter 51: In the Sports Festival arc in the manga, one of the Sisters gets kidnapped, and Mikoto is forced to stay behind while her friends do all the work, since mind-controlled minions are keeping a close eye on her, and she's not willing to kill them to escape. Until one of said friends gets hurt. She just walks right past, in a straight line towards her goal.
-->'''Mikoto:''' "Unless you are prepared to kill me to stop me, ''get out of my way''."
* Chapters 51 & 52: [[TheDividual Wannai and Awatsuki]] completely out maneuvering Baba and his robots leading to his complete defeat.
* Chapter 54: In the face of a girl who is threatening her, Kuroko (who is in a wheelchair) teleports out of the wheelchair, over the girl, and throws the damned thing at her!
* Chapter 63 of the manga sums up why it's awesome on the very last page: [[spoiler: "The unprecedented combo of Touma and number seven act to stop Mikoto's rampage!!"]]
** To put it into perspective, [[spoiler: this is the first time the two of them ever meet. At first, Gunha dismisses Touma as another normal until the both of them NoSell Mikoto's beams mid-conversation, which then leads the two of them to team up. The fact they are very similar means Touma befriended another Level 5.]]
** To get around Touma's [[AntiMagic Imagine Breaker]], [[spoiler: Angel!Mikoto starts flinging massive piles of scrap metal in all directions. And just before she can connect a large ball of it towards him, Gunha does a BigDamnHeroes and obliterates the scrap ball.]]
* In Chapter 68, Kuroko [[spoiler:blocks a knife... by letting it embed into her palm. She doesn't even show a twinge of pain and then proceeds to [[CurbStompBattle curb stomp Mitori]].]]
** Also from Chapter 68, [[spoiler: Misaki tricking Gensei into entering Exterior's self-destruct code by switching her own concepts of it and the limiter release code, along with erasing her own memory of doing so. The failed Graviton Panel plan was just a ruse to make Gensei think he had won.]]
* Chapter 69: [[spoiler:Touma takes charge of the situation and has Gunha clear a path for him while he runs up to Mikoto. Her out of control powers obliterate his right arm, only for the dragon to come out and finally change her back to normal. His arm grows back and he nonchalantly says saving her was no big deal before covering her naked body up with his jacket.]]
* In the Dream Ranker arc Mikoto faces off against [[spoiler: an android with the ability to project its soul into, and thereby take control of, any nearby physical matter. After some back and forth the android rips up half a city block and becomes a kaiju-sized engine of destruction. How does Mikoto respond? By creating her own kaiju-sized monstrosity out of an equivalent amount of iron sand!]]
