History Awesome / ACertainScientificRailgun

* Most of the finale for Railgun S: 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.

* Railgun S Episode 15-16: Touma vs Accelerator. Though this was already shown in [[Literature/ACertainMagicalIndex 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 from Touma, and the Level 5 is laid out on his backside in the gravel. Cue freak-out, and a desperate attack. The fight continues on for a few moments with Touma having the upper hand until Accelerator begins to gather the plasma ball.

** Misaka 10032 ends up subbing in for Mikoto during balloon hunter. When the opposing team finally corners her with enough firepower for her more talented sister, 10032 shows off her impressive acrobatic skills, taking down at least 4 opponents before being eliminated. And her elimination was at least partially due to the shock of a tranquilizer dart....

** One of the Sisters gets kidnapped for reasons unknown, 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. That is until one of said friends gets hurt. She just walks right past, in a straight line towards her goal.
--->'''Misaka:''' "Unless you are prepared to kill me to stop me...''then move''."

** To get around Touma's [[AntiMagic Imagine Breaker]], 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.

* Railgun T, Episode 14: 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 8 dragons to come out and eating the giant black sphere she created, finally changing 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.

** Mikagami Nagisa has the power to control oil; ie, fat. She became a political force practically by accident. Then when some of her subordinates are attacked, she demonstrates that this power is worth ''far'' more than just shedding unwanted pounds. One second she's as thin as a rail to run faster, in the instant before she lands a punch she suddenly gains a hundred pounds, when she's tied up she sheds the weight again to escape, and then she body-slams her opponent while she's the size of a weather balloon. All while demonstrating advanced martial arts techniques.

** In probably one of the most BeyondTheImpossible moments in the ''franchise'', Uiharu's strange new power isn't even a natural state or something deep within herself like a Level 5 might pull out. She instead straight up hacked AIM Jammers and then ''modified her own AIM field in real-time'', essentially producing an impossible Esper with the exact means to be able to cut off Kimi's power source from her black hole generation, presumed to be by somehow digitizing space around herself to modify it precisely. This is not only something not a single person nor computer in Academy City, or the entirety of the Science side in general, has ever managed to do, but just through her hacking abilities that have to make her mind one of the most advanced in the planet, she effectively became a '''RealityWarper''' to be able to accomplish this feat, even if only temporarily. And all on a spur of the moment IndyPloy with absolutely no hesitation nor any backup plans, all to bail her friends out of an otherwise completely unwinnable battle.

* Season 1, Episode 23: Mikoto is outnumbered and outmatched by a company of PowerArmor mooks. [[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.

** 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.

--->'''Mikoto:''' "Unless you are prepared to kill me to stop me, ''get out of my way''."

** Later on, Mikoto obliterating Baba's giant mantis robot, tracking down his location, and puting him to rout by sheer intimidation.
