* [[CrouchingMoronHiddenBadass A young and seemingly inept Mafia boss]]? Check. [[ImpossiblyCoolClothes Black & White Mafia standard suit]]? Check. [[PowerFist Kick ass combat gloves]]? Check. [[ImpossiblyCoolClothes Pimp ass Mafia cape]] made out of a [[KillerRabbit pet lion]]? That's a big [[PrecisionFStrike fucking]] '''CHECK!'''
* Reborn using the [[PrecisionFStrike F-word]] [[spoiler: when the boss of the Arcobaleno and granddaughter of a friend gets threatened.]]
** In Chapter 122, he finds out Xanxus' plans [[spoiler:involved placing the 9th in Gola Mosca which was draining his life force and killing all of Tsuna's guardians at once.]] After he says this the Cervello tell him that he should refrain from making accusations against their opponents. He basically tells them to go screw themselves and for the first time they look terrified.
** In the anime. Reborn and ''[[CoolPet Leon]]'' get several during the Arcobaleno Trials. Taking out [[{{Badass}} H]][[{{Determinator}} i]][[{{OneHitKo}} b]][[{{CurbStompBattle}} a]][[{{OneManArmy}} r]][[{{MajorInjuryUnderreaction}} i]] with one move? Yup it's there. Demanding EVERYONE to attack him all at once? Check. Taking them all out with not one of them even landing a hit on Reborn? Check. Shooting down Tsuna in Hyper Dying Will Mode with his ultimate attack? OH YES! And it's implied that Reborn was ''barely'' using his strength. Tsuna only managed to get a scratch on Reborn because Reborn gave him a chance to! If Reborn got a little serious, the entire episode would probably last 5 minutes. Reborn is a '''BADASS'''.
* Any moment involving Tsuna [[spoiler:getting shot by the Rebuke Bullet]] is a Crowning Moment of Awesome.
--> '''Tsuna:''' "If I were to lose a dear friend right in front of my eyes...I'd never be able to die in peace!"
* How can you not mention Tsuna's fight with Mukuro in the Kokuyo arc? AWESOME. Especially the end where he ''fucking slams his X-Gloves into Mukuro's face'' and then forces him to the ground, where he passes out.
* Chapter 98: Twenty Years into the Future [[spoiler: Lambo]].
* Chapters 116 & 117: How has Mukuro's [=CMoA=] in Chrome's fight with Viper not up here yet? Chrome's getting completely overwhelmed, only to have Mukuro intervene and [[CurbStompBattle shred]] the punk. Just that fact that he can out-cast the master illusionist of the Arcobaleno is badass in and of itself.
* Chapter 125: Reborn gets one in this circumstance when the Sky Ring Battle commences. The Cervello tell him that once the fight starts, nothing interferes; no advice, no special bullets, nothing. Then Xanxus punches Tsuna in the face. The following dialogue ensues:
--> '''Xanxus:''' "Oh, I'm sorry, did I get him before he could be shot with his bullet?"
--> '''Reborn:''' ''(twirls smoking gun)'' "Nonsense, who do you think you're talking to here?"
* During Tsuna's fight with Xanxus, when he first utilizes his X-Gloves. This was made even more awesome when Xanxus unveiled his guns, only for Tsuna to calmly suggest that they "try them out" and see who is strongest. Then he attacks. His BadAss levels ''sky-rocketed''.
* This troper never liked Ryohei much, but still found the fact that in Chapter 132, he [[spoiler:demolished the school gym with one punch]] very very cool.
* Regardless of whether they won or lost, every main character got one in the Rings Battle.
* Chapter 153: Gamma reveals to Gokudera [[spoiler: that the Tenth Vongola Boss was gunned down in plain view of many of his subordinates]]. Gokudera then dives into a fight with Gamma he definitely won't win. When he loses Gamma tortures him for information and Gokudera responds by ''spitting in his face''.
* Chapter 164: Chrome creating real illusions of her allies during her fight with Glo Xinia.
* Chapter 240: Byakuran [[spoiler:comes out of the sky and shoots a giant laser from his eye]]. This may not be a CMOA, but it is definitely a Crowning Moment of some sort.
** Within that same chapter, Tsuna's family had to raise five million fiamma volts; something treated by the others as absurd. They are given a brief period of time to do so, and wait until the last second anyway (as they were waiting for Yamamoto and Hibari to show up.) Then, within the last possible second, they [[spoiler: simultaneously open their Vongola Boxes and proceed to achieve ''twice the required amount''.]] Even ''Byakuran'' stopped smiling by that point! [[StepfordSmiler BYAKURAN!!]]
* Chapter 250: [[KillItWithFire "I'm out of the illusion."]]
** Explanation: Tsuna was trapped in an illusion that made him fly in circles. He X-BURNER'd his way out.
* Hibari... just Hibari. He might as well be a living example of a Crowning Moment of Awesome.
** His battle against Gola Mosca in Chapter 119 is all the evidence you will ever need.
** You mean despite the fact the fight was fixed?
*** He managed to [[spoiler:rip off the arm of a robot within seconds after promptly crushing its head using his Tonfas. Fixed or not, winning the ring in less than 5 minutes? With a robotic juggernaut? Genuine CMOA material right there.]]
*** Not to mention the robot was said to be invincible by Tsuna's dad and company.
*** [[http://www.mangahere.com/manga/katekyo_hitman_reborn/v14/c119/17.html And looking at the reactions of almost everyone]], they were NOT EXPECTING anything like this.
* Chapter 226: Xanxus tells Rasiel that, regardless of internal conflict, in times of crisis the Vongola are always one. Then he blasts him. ''Awesome''.
--> '''Xanxus:''' "Regardless of our internal strife, in times of crisis, when we are attacked by scumbags from the outside... We, the Vongola, are always... as one!!"
** All the while not moving from his chair.
** See the fight, along with the above quote [[http://www.youtube.com/watch?v=uSmv0YxLoaw here]].
* Hibari appears in Chapter 261[[spoiler: to have killed Daisy of the Real Six Funeral Wreaths with his Vongola Box.]]
** Using ''handcuffs''.
*** Well but ''that's Hibari''. I'd also like to point out how, during the Sky Ring Battle, Hibari managed to overcome ''poison which could've killed an elephant'', knock down a pole and save himself while everyone else was still either agonizing or being saved by someone else. And then he appeared in front of Belphegor to just, generally, be awesome.
* Chapter 264: Fran of the Varia gets one by [[spoiler:tricking the Vindice and having them release Mukuro instead of the last of the Six Funeral Wreaths, Ghost]].
** It helps that apparently [[TheGuardsMustBeCrazy the guards are idiots]].
---> '''Vendicare Prison Guard:''' "Who ever could trick us? There are just three illusionists who are strong enough..."
* Chapter 266: Gokudera after over 250 chapters [[spoiler: has openly defied Tsuna's direct orders. Thus getting quite the 'Oh shit!' reactions from everybody]].
* Chapter 268: Lambo managed to [[spoiler:beat Kikyou's dinosaur box animal with his Vongola Box Weapon. Granted not the most amazing method... but ''he just killed a fucking dinosaur'']].
** Not just one...7-8 OF THEM.
** And the owner of those dinosaurs, [[spoiler:Kikyou]], is the one that claims to be the one with the most power of the Six Funeral Wreaths.
*** And the owner of those dinosaurs just got PUNCHED in the face by Ryohei. Seriously. Punching [[spoiler:dinosaur-hydra-monster-thingies]] in the face? Can't get much more extreme.
**** And the said owner also claims him to be hands down the strongest human he has ever fought.
* Chapter 270: After the dinosaur spam, [[spoiler: Mukuro shows up with an [[BigDamnHeroes illusion]] that not only tricked the Six Funeral Wreaths but was enough to have them use each of their hell boxes first. On top of this, he did so ''without''using a Vongola Box]].
** His and [[spoiler: Fran's]] [[BigDamnHeroes entry]] ''was'' a CrowningMomentOfAwesome of epic proportions.
* Chapters 275 & 276: [[spoiler: After Byakuran's power-up, and [[CurbStompBattle "round"]] with Tsuna, Reborn still believes that Tsuna will win. ''Even after it appears that he slit/cut/crushed his neck.'']]
--> '''Reborn:''' "Don't underestimate the strength of Tsuna's Dying Will. Besides, I'm not talking about whether you can win. ''Tsuna, you've got no other choice than to defeat Byakuran.''"
* Chapter 278: [[spoiler: Tsuna just got a AwesomeMomentOfCrowning by being officially accepted as the [[AwesomeMomentOfCrowning 10th Vongola Boss]] ''from the '''First''' himself''. A little later on, he turned that into Crowning Moment of Awesome with the amount of power he just received by blocking and countering Byakuran who just easily Curbstomped him not so long ago.]]
--> [[spoiler:'''Vongola Primo:''' "Now give that Mare boy what he deserves."]]
** And just a few pages later:
---> '''Byakuran:''' "Haha, too bad. I've only shown eighty percent of my power so far."
---> '''Tsuna:'''[[spoiler: "I've only shown half."]]
---> [[spoiler: Cue reversal of the [[CurbStompBattle curbstomping]].]]
** And then Chapter 280 got [[UpToEleven EVEN MORE ''EXTREME'']].
* In Chapter 293, Kaoru gets one for [[spoiler: critically injuring Yamamoto of all people considering how he runs on "instincts" so damn well to the point of hospitalization is pretty badass regardless of his [[FaceHeelTurn face heel turn]].]] This is continued in Chapter 294 when Tsuna quite simply sent shivers down my spine for [[spoiler: accepting the ceremony to fish out the culprit knowing full well where this choice is taking him. Note that he did this ''without his Dying Will Mode'']] ''[[{{Squee}} Shit just got real.]]''
* Chapter 298... did.... did Enma just...[[spoiler:... just utterly ''[[CurbStompBattle wreck]]'' everyone, destroying their [[DeadlyUpgrade Upgraded Vongola Rings]] on a '''seventh''' of his power? How goddamn powerful IS he?]] The chapter title is [[ExactlyWhatItSaysOnTheTin exactly what it says on the tin.]] Needless to say, it was totally badass from a [[spoiler: villain's point of view]].
* Chapters 312 & 313: [[spoiler: Lambo defeating Ooyama without outside help and without turning into [[FutureBadass 25 Year Old Lambo]], marking his first victory in the series.]]
* Chapter 320: "Well then, you should equip your Vongola Gear, Hibari Kyoya." Badassery in 3... 2... 1...
** On that note: Hibari vs. the 500 "invincible" ice clones of Adelheid Suzuki. Guess who wins.
* In Chapter 325, [[spoiler: Yamamoto]] shows us how to flawlessly pull off a proper BigDamnHeroes.
** He has a habit of pulling off a number of BigDamnHeroes moment, like saving Gokudera and Ryohei from [[spoiler:Ghost's flame absorption]].
* Chapter 334: Mukuro defeats [[spoiler:Daemon Spade]] by demonstrating that trying to slow him down with illusion of his friends will not work.
** Of course, Daemon Spade gets props too, especially since [[spoiler: in the next chapter it's revealed that his loss was just a gambit to possess Mukuro's body.]]
* Chapter 340: Enma is willing to sacrifice himself in order to defeat Daemon Spade. Even if it ends up not happening... wow.
** Chrome in the very next chapter jumping in front of Enma to protect him from the XX-Burner. [[FauxActionGirl Poor combat skills]] or not you can't say the girl doesn't have guts.
*** ....Well, illusionary guts, anyways.
* Chapter 360: Iemitsu defeats Tsuna with a ''single punch''.
* Chapter 361: "The Arcobaleno Skull has been approved to enter the battle!" [[OhCrap OH SHI-]]
* Chapter 363: [[spoiler:Gokudera and Yamamoto successfully escape ''[[ImplacableMan HIBARI]]'' without getting their watches broken.]]
* Chapter 366: "The Arcobaleno Colonnello is approved to enter the battle!" Cue {{BFG}}.
* Chapter 369: [[spoiler:[[BigDamnHeroes Adult Reborn shows up to save Tsuna]] from Iemitsu's attack]]. "It's lesson time. No-good Tsuna" indeed.
* Chapter 370: [[spoiler: Iemitsu vs. Adult Reborn]].
* Chapter 372: Fon vs. The Varia. [[spoiler: Varia's on the ropes.]]
* Chapter 381: Mukuro uses his flesh eating crow illusion on the Vindice.
* At the end of Chapter 382, [[spoiler: Chrome shows up to help against the Vindice while telling Mukuro that she will help with the illusion and fight as well.]] She does so even though she's "seriously ill" as M.M. says.
* Chapter 383: [[spoiler: Chrome proceeds to use her own illusions to replace her organs, showing that with her new found motivation she has a very powerful Dying Will Flame. She then combines her illusions with Mukuro to make [[http://manga.animea.net/katekyo-hitman-reborn--chapter-383-page-16.html THIS]].]]
* Chapter 385: Reborn basically tells Bermuda to [[ShutUpHannibal go screw himself]] after being offered the opportunity to join him.
* In Chapter 390, Tsuna tells Reborn that he's a failure as a home tutor and he's not gonna let Reborn die.
* Chapter 402: Reborn vs. Bermuda. [[spoiler: And then Reborn shoots Tsuna with a Dying Will Bullet while Tsuna's in Hyper Dying Will Mode.]]
* Chapter 403: Tsuna epic one punch defeat of Bermuda.
