* Chapter 148: After training on Greed Island, Killua goes back to take the Hunter's Exam. 1489 people including himself joined that year. The goal of the first trial is to take five tags from five other participants, and present them to the Hunter in charge of the first trial. Within one and a half hours, Killua takes ALL of the tags from every participant, resulting him him passing the Hunter's Exam within record time.
* Gon flipping the stone in Heavens Arena with his bare hands and using it as cover to finally land that punch on Hisoka
* When Gon [[spoiler: is finally allowed back into the Chimera Ant fight]], Morel remains unconvinced he can be useful, and demands Gon hit him with his best move. Gon's fury-fueled Jajanken is so intense not only does it terrify Morel, who is leagues above him, but also ''everyone in the vicinity'', who are all also way above his power level besides Killua. Gon later remarks that it ''would have killed Morel had it landed.''
* Gon's entire fight with Genthru. Not only does he [[spoiler: sacrifice his hand and a chunk of his other arm]] just to get a hit in, causing Genthru to call him the crazy one, but he also manages to still win with a well-executed strategy. And who could forget "First comes rock!"
* [[spoiler: Gon annihilating Pitou in just two hits.]] [[http://www.mangafox.com/manga/hunter_x_hunter/v28/c306/9.html First]]. [[http://www.mangafox.com/manga/hunter_x_hunter/v28/c306/10.html Comes]]. [[http://www.mangafox.com/manga/hunter_x_hunter/v28/c306/12.html Rock]].
** [[spoiler: Following that, Gon ''stabbing through Pitou's torso with his own sliced off arm.'']] Can you say [[BadassAdorable GARmoe]]?
** [[spoiler: And following ''that'', Gon producing a large enough Jajanken ''with his stump'' that it produces a DBZ-rivaling blast.]]
* Leorio's [[TheBusCameBack return to the spotlight.]] He publicly calls out [[spoiler: Ging for refusing to visit his hospitalized son.]] Words don't seem to have an effect, so he flips him off and sends him flying with an uppercut, courtesy of his brand new Nen ability. In-universe it's acknowledged as awesome enough for a standing ovation and [[spoiler: enough votes for him to take over as hunter chairman to rocket him from an unknown to third place.]]
* The entirety of the fight between [[TookALevelInBadass Kurapika]] and [[TheBigGuy Uvogin]]. In fact, any climax of the entire Yorkshin arc may account for this.
** During the Troupe's attack at the auction, Zenji antagonizes Kurapika for not partaking in all the action and instead following his boss's orders to get Neon to safety. Kurapika, having other things to worry about, dismisses him with a fist in his face. In both adaptions, the impact puts Zenji on his ass, with a broken nose. In the 1999 adaption, he is [[PunchedAcrossTheRoom sent flying into the wall, spinning no less]]. He attempts to exact his revenge by thwarting Kurapika's duty to purchase the Scarlet Eyes, but this fails. Then, desperate to one-up the Kuruta, already pissed off and depressed because of the events of that night, he intercepts him on the street, preparing to shoot him with a handgun. Once Kurapika lifts his chin, revealing his own blazing [[RedEyesTakeWarning scarlet eyes]], along with a [[TranquilFury token of advice to not fuck with him]], Zenji drops to his knees in terror.
** Even though Uvo did end up gettting his ass handed to him by Kurapika, the way he went out shows just how badass he is. Even after Kurapika set the Judgement chain on him and asked where the other troupe members are, [[GoOutWithASmile Uvo merely scoffed]] [[FaceDeathWithDignity and said "You know what you can do with that question? Idiot."]]
* Even before Nen was introduced as a power, the series had a high amount of awesome. During the final fight of the Hunter exam for example, Gon displays his {{Determinator}} skills in his fight against [[CrouchingMoronHiddenBadass Hanzo]] -- by fighting on even after the guy breaks his arm.
* Also notable are a few moments from the third part of the Hunter Exams. The heroes face off against a group of former criminals, each of which trying to challenge them in a different way.
** Kurapika and Killua both [[CurbStompBattle curb-stomp]] their respective opponents.
** Gon tricks his opponent into defeat.
** And Leorio uses his skills as a doctor to force Kurapika's opponent (who [[spoiler: was playing dead) to give up.]]
** And Tompa gets one for being a [[spoiler: bastard full of Schadenfreude and getting away with it. At least up until the next part of the exams.]]
* Killua proves once again that he is capable of curb-stomping just about anyone during his fight against a triplet of rival aspiring hunters in the fourth part of the Exams. He defeats all of them without getting a scratch.
** Also [[spoiler: Gon escapes a cave full of poisonous snakes and sleeping gas. By holding his breath. For nine minutes. While carrying his friends.]]
*** [[spoiler: But first he has to get the antidote to the snakes from the guy who put them there (who's sitting in the cave as well and is now dead, half the snakes commanded to guard his corpse) to save Leorio. His solution: Just reach on in there and get bit by ''every single snake'' while he fishes around for the antifote.]]
** Killua gets another one in the [[spoiler: second Hunter Exam he takes. Out of 1498 candidates, he's the only one who managed to pass the exam. Because ''he defeated everyone else in the first phase within one and a half hours.'']]
* Silva's DynamicEntry during the Chimera Ant arc consists of him coming down from the sky with enough force to [[spoiler: squash a commander-level Chimera ant like the insect that it is.]]
** And before that, [[BadassGrandpa Zeno]] turns his Nen into a dragon.
* Netero [[spoiler: not only displays Nen skills no other Hunter in the series had ever shown before, he also blows himself up in a [[FantasticNuke NUCLEAR EXPLOSION]] to finish the Chimera Ant King.]]
** Which, by the way [[spoiler: works in the end.]]
** [[spoiler: How it works is a CMOA in and of itself for Togashi. Typical Shounen series would do one of two things. The villain would be vaporized or would survive. [[TakeAThirdOption The villain survives, and is soon restored back to full health plus some by his underlings (typical shounen) only to have it revealed he and several others who survived nearby are still dying because of radiation poisoning.]]]]
* Chapter 334 [[spoiler: when Pariston explains his and Ging's modus operandi.]]
* Kurapika using his brand new Nen chains to - not deflect, not dodge - but CATCH bullets fired at him during his first Hunter assignment. In the original series, the entire scene is made up him swiftly whipping the chain this way and that, skillfully taking the visual {{Badass}} level up to a gazillion.
* Gon's BatmanGambit against Bat and Owl, using their formation to lure Bat to a mountain side before picking up a tree and smash her with a giant gust of wind.
* Gon breaking Illumi's arm.
* For a villainous example: Uvogin is paralyzed from the neck down and faced with three highly skilled, super-powered assassins. What does he do? [[spoiler: He ''bites the the top half of the first assassin's head off'', spits it out with such force that it shoots right through the second assassin, and then yells so loud he explodes the third one's brain.]]
* Killua [[spoiler: ripping out [[SerialKiller Jones the Dismantler's]] heart before he even realizes it]], then crushing it in his bare hands. It's the first time we get to see just how [[BadAssAdorable badass]] Killua really is.
** That's just in the manga. In the 2011 version, he takes the heart and then [[AndShowItToYou smugly bags it up and plops it into his out reaching hand.]] And then goes right back to the group, bored out of his mind, asking of it's over already.
* Gon calling out the Genei Ryodan on their MoralMyopia and then proceeding to [[BreakingtheBonds breaking the chains]] to show that he and Killua are NOT to be taken lightly.
* How about [[MonsterClown Hisoka]] using his nen-forgery skills to pull a BatmanGambit on [[DangerouslyGenreSavvy Chrollo]], of all people ?
* Ging's description of Leoro's [[spoiler:new Nen ability]] and his theory for why Leorio created it: [[spoiler:as a surgical tool. Leorio can literally ''punch out cancer''.]] Bonus points to Ging since he [[spoiler:copied said power after being hit by it once.]]
* At one point of the Exams, the group, plus Tompa, get to the final obstacle: choosing between leaving three people behind by taking the short path, or choosing the long path that would allow them to go all of them together. After a very long debate between Leorio and Tompa (also discovering that Tompa was planning to wait untill all of them would off the others), Gon managed to convince the group to vote for the long way. The solution? [[spoiler:[[TakeAThirdOption They chose the long path and made a hole in the wall to take the shortcut]]]]. Even the examinator was impressed.
* Phantom Troupe vs the Chimaera Ants in Meteor City. The Chimaera Ants in question are the ones responsible for [[spoiler:Ponzu's death]] and [[spoiler:Pokkle's capture]] earlier in the arc. [[LaserGuidedKarma The Phantom Troupe obliterate them.]]
** [[DanceBattler Bonolenov]] vs the Gun-toting ant. During the fight, the Gun-Toting Ant (the same one who [[spoiler:killed Ponzu]]) made fun of Bonolenov's people, the Gyudondond, and their music. Bonolenov, [[BerserkButton insulted by this]], then drops a sphere in the shape of Jupiter on top of him, squashing him.
** Phinks vs Gorilla Chimaera Ant. The Gorilla taunted Phinks' punches for being weak, and offered to give Phinks a free punch. Fifteen wind ups of his arm later, and Phinks obliterates the Gorilla with [[MegatonPunch Ripper Cyclotron]].
** Feitan vs Zazan. Four words: Pain Packer - [[PowerOfTheSun Rising Sun]]. Don't make Feitan angry, [[UnstoppableRage or you will not live past the next minute.]]
* A minor one, but Palm's BadassBoast after [[spoiler: Killua finally helps her regain her memories.]]
--> "My name is Palm Siberia. I am a ''human''. [[spoiler: I will never be like you Ants!]]
* Just a little bit from ''The Last Mission''-- in Gon and Killua's absence, Zushi-- small, not quite powerful little Zushi-- became powerful enough to get to the 200th floor and become a ''Floor Master''. For context, the Floor Masters are the top 10 fighters in the Arena, which would normally take upwards of months or years to do. Zushi was still a kid at that point. No more than a couple of ''months'' could have passed since Heavens Arena. [[BadassAdorable Wing was right on the money with that "one in 300,000" speech.]]
** The introduction to Nen (for both Killua and the audience) wasn't shoddy either. Killua was ready to knock him out with one chop, just as he had done with almost all of his arena opponents beforehand. But when he does it, Zushi not only gets back up, but he changes stances to try and use Nen on the offensive. And kept doing it every time he was chopped, even though he was very visibly becoming exhausted and in pain. This utterly ''baffled'' Killua-- not only is this kid [[{{Determinator}} not staying down as intended]], but the aura surrounding Zushi ''threw him off'' because it reminded him so much of Illumi. The only way Zushi was put down for the match was when he tossed him into the Arena walls.
* ''All'' of Gon's fight against Hisoka in Heavens Arena. Especially in the 2011 series, where there's not much in the way of internal dialog, not much talking, no music, no nothing. Just a short, intense fight punctuated by the sound of fists flying through the air, with authentic sports commentary throughout. And then it becomes so, ''so'' satisfying when Gon actually connects right to Hisoka's face.
