The Chimera Ant is a top-level quarantined creature due to its dangers to other species. They can copulate with a female of any species and endow her with the abilities of a Chimera Ant Queen: Anything a queen consumes will incorporate its DNA into the queen's offspring; she will then give birth to Mix-and-Match Critters of random things she's eaten. Such offspring will receive the best physical advantages of everything it's based on. For instance, a Chimera Ant that's part human will have human intelligence and the ability to speak.
Oh, and by the way, they're human-sized.
- Alien Blood: They bleed dark blue.
- Assimilation Backfire: Though taking human DNA making them stronger, smarter, and more powerful, it leads to their downfall by giving a sense of individuality, which creates rivalries and ambitions that tear apart the army.
- Authority Equals Asskicking: The King plus his royal guard are the strongest possible creatures produced by the Queen.
- Big Bad Wannabe: A number of them chafe at following orders and express a desire to set out to carve empires of their own. They get their chance when Queen dies, but they're put down before they can really get started.
- Big Creepy-Crawlies: Up to Eleven.
- Bug War: What they trigger, a much more strategical and Shounen variant to the norm given how smart the "bugs" are.
- Call a Smeerp a "Rabbit": While some information about the Chimera Ants demonstrates some surprising depth of knowledge, most of the "ants" look nothing like insects in the least. A few will have a mammal's body and insect-like limbs, for example, while others will look like a combination of several non-insect animals, while another simply looks like a large cartoon penguin. Just a penguin.
- Then theres the pink mafioso koala in a tuxedo, out, alone, in the middle of the forest. He has to verbalize his loyalty to the queen to know hes related at-all to the ants.
- The series at least tries to justify this by adding the special factor that whatever a Chimera Ant Queen eats is 'assimilated' into their potential genetic chain, to the point that humans devoured can even regain their memories of their past life regardless of their new form.
- Combine the above issue with their human behavior, and theres really nothing distinguishing the ant threat from pretty much any human adversary.
- Character Development: The King, Pitou and Youpi arguably go through more of this than even the protagonists, especially the King. Each one is more detailed in their respective folders. The ants themselves begin to evolve a sense of morality as soon as the first humans are consumed, and this theme permeates all of the development of the ants.
- Darker and Edgier: Their arc is significantly the darkest of the series thus far. Previous arcs had body counts in the tens- this has it in the hundreds.
- Extreme Omnivore: At least of the types of life forms they eat, varying to small critters to Nen-infused humans, the latter being very troublesome as it grants newer Chimera Ants deadly intelligence, and later Nen powers.
- From Nobody to Nightmare: From a mere species of habitat destroying insects to near deities that caused the biggest calamity to the Hunter's Association with the deaths of Gon's mentor Kite, as well as Netero, the then head of the Association.
- Genetic Memory: A number of the Chimera Ants are able to remember their past lives before they were eaten and their genetic material was mixed. Some even remember up to the moment they were eaten alive by the queen herself.
- HeelFace Turn: A number of them abandon their predation of humanity after the Queen dies and more them begin to recover their memories.
- Hero Killer: To establish their Darker and Edgier traits, they're often shown killing established characters quickly, especially Kite.
- Hive Caste System: Divided into ranks, with soldiers of higher ranks usually, but not always, being stronger and more intelligent than their subordinates. The Royal Guards and the King take this concept Up to Eleven, being born superior to anything else in the hive. Subverted in that the Queen has shown no great fighting skills.
- Horde of Alien Locusts: Played with. Despite their alien appearance, they're born on the Hunter × Hunter planet, they're also a significantly more cunning than your usual alien swarm.
- Humanity Is Infectious: Played for horror, as the assimilation of humans into the later Chimera Ants makes them not just smarter, but capable of actively malicious behavior that wasn't present in earlier drones.
- Knight of Cerebus: Hisoka, the Phantom Trope and the Bomber still had some restraints and weren't serious enough for the Hunter Organization to be considered a threat. The Ants on the other hand not only required the top brass in order to even fight with them, they kill off some of those brass like Kite and Netero with little effort. More importantly, the majority lack restraint to kill without wanton regard to others and some quite kill very casually as seen when a Leol\Hagya eats a reporter's head to prove a point that they were the real deal.
- Mix-and-Match Critter: There's cat, butterfly, bird, armadillo, wolf, and whatever Youpi's supposed to be.
- Only One Name: All of them.
- Past-Life Memories: Some of the Chimera Ants retain or gain memories of their past lives as humans or other animals. These memories become important to their motivations or HeelFace Turns.
- Reincarnation: Some develop memories of their past lives over time, which becomes a plot point.
- The Starscream: Thanks to their human genetics the ants slowly begin developing their own ambitions and chafe at being under the Queen's thumb sometimes disobeying orders to hunt down "rares" themselves. Once she dies most of them go their separate ways to try and become Kings in their own right. Even the ones that do return to the fold and serve the King have ambitions to overthrow him.
- Strong Ants: Justified. They are giants, not really gigantic, just human sized, which is considered huge for an insect.
- Theme Naming: The Royal Guards' names can be split into two halves. The first half is a lesser-known Egyptian god (Nefertem, Shai, and Montu), and the second half is a character in the children's books Caroline et sus amis (Pitou, Pouf, and Youpi).
- Was Once a Man: A lot of them.

One day, a dying Chimera Ant Queen washed up on the shore of the country of Neo Green Life, a place with an agrarian culture and no weapons, off limits to everyone except those with special permission. She had enough strength to create a few offspring and made a small hive nearby. Said offspring was able to slaughter the locals and create havoc. However, the inhabitants of this country would rather stick with tradition than call for outside help, at least publicly. By the time an investigation team could enter Neo Green Life, the Queen had already consumed nen-powered humans and recovered from her injuries (but not completely), and the team had its hands full with her offspring. When it came time, the Queen gave birth to the King, who killed her immediately. Afterwards, some of the ant commanders left her now-massive hive and set up their own empires in other countries.
The Queen is not able to speak. Instead, she communicates telepathically with the other Chimera Ants, who all have this ability. In spite of being surrounded by powerful nen-powered ants, the Queen has no nen control and no fighting ability.
- Death by Childbirth: Subverted. Her son forcibly birthed himself, causing wounds which nearly killed her. She fights to live for her son's sake, but the moment she hears of his strength, she happily lets go.
- Mega Manning: Technically, she spawns a Mix-and-Match Critter every time she eats something... when she starts on humans, they become intelligent, and when she eats someone with Nen abilities...
- Monster Is a Mommy: NOT an excuse this time, as the Queen commits some terrible acts all for the sake of her race.
- Nice Job Fixing It, Villain!: In hindsight, eating mostly humans led to the ruin of her hive. While eating humans did increased her offspring's intellect and strength, the sense of individuality and humanity and, in some cases, memories of their past lives made most of them go their separate ways and even aid the humans in defeating the other Chimera Ants.
- Non-Action Big Bad: She's the primary antagonist of the first part of the arc, but never leaves the hive. She can sense nen, but cannot use it herself.
- No Name Given: Justified since the Ants didn't have an understanding of the concept of names till her human-based offspring started learning it. While her children received names of their own, she never thought to give one to herself.
- Telepathy: How she communicates with other Chimera Ants. It appears to be a bit painful for the receivers.
- The Voiceless: She and her early offspring only communicate via telepathic links, as she doesn't have the physiological features to allow for voice; only her children that came after she began consuming humans were able to achieve vocalization.
- Wacky Cravings: Fish, centipedes, people...

When a Chimera Ant Queen has gestated enough, she will give birth to the King—the strongest Ant possible, gifted with all of the best traits possible.
The Queen's masterpiece and crowning achievement, the King is by far the strongest Chimera Ant she created and was born with the best traits of everything she had ever consumed, including intelligence off the charts. He began as completely ruthless, splatting even fellow ants' heads if they did so much as hesitate when he gave an order. The King moved to the neighboring country of East Gorteau, a brutal dictatorship not unlike North Korea, and immediately took charge there. The King has the ability to, upon death of a nen-powered individual, absorb his or her nen into himself, though it manifests as raw power rather than Mega Manning. Due to this, he has manipulated East Gorteau's entire population to be killed off except for those with nen control, whom he'll kill and consume himself.
Out of boredom, he called in champion players of various board games, such as chess, shogi, and go. He kept playing against them until he defeated them, then killed them off. However, he met his match in a blind girl named Komugi, East Gorteau's gungi champion. No matter how much he plays her, she curbstomps him every time. Having such a brilliant mind and no way to fend for herself, the King starts to feel sorry for her and also begins respecting humans and other creatures. The King's sympathy towards Komugi eventually grows into casual chatter and then outright affection for her, spurring Shaiapouf's envy. Netero is his first opponent in combat who gives him a good fight, though by then, he has become appreciative of talented people, Netero included, and would rather not fight. He is forced into it anyway and kills Netero. Netero's death, however, sets off a nuclear device, detonating the palace and nearly killing Meruem, who is revived by his guards, but becomes afflicted with amnesia. After a series of events, it's revealed that the device's radiation has given him severe cellular degeneration, and that Pouf and Youpi have died due to this. After reuniting with Komugi and playing Gungi one final time, he dies in her arms.
- The Ace: Good at everything, explain to him the rules of any game, he will learn them quickly and beat you, easily. The ego this gives him is rather large, but it's eventually deconstructed when he begins to realize there's Always Someone Better.
- Affably Evil: Becomes a caring Well-Intentioned Extremist by the end of his arc.
- Ain't Too Proud to Beg: Perhaps one of the most dignified examples. He comes very close to kneeling before Palm to ask for her help in finding Komugi before she stops him, her chimera half unable to bear the sight of the king brought so low.
- All Your Powers Combined: After consuming Youpi and Pouf's bodies Meruem gains more refined and powerful versions of their abilities. From Youpi's side he gains the ability to grow wings which allow him to travel faster then his Royal Guard (it's stated that, form where they where, it would take 15 minutes to reach the palace. For Meruem it only took 5) and a more controlled and concentrated version of his rage blast powers. From Pouf's he gains his own version of Spiritual Message by dispersing his Aura which allows is so powerful it allows him to read peoples minds.
- Always Save the Girl: He is always there to rescue Komugi.
- Always Someone Better: Despite his immense pride, he takes this surprisingly well- his constant losses to Komugi make him more determined to beat her, and the constant challenge she provides him both entertains him and teaches him the worth of other creatures.
- A more terrifying version of this comes into play with the revelation of the existence of the Dark Continent, which the ants originally hail from. Apparently, in comparison to some of the disasters that emerge from there, the Chimera Ants, including Meruem, are one of the tamer ones.
- Always Second Best: In Gungi, he is always defeated by Komugi.
- Anti-Villain: While in the beginning, he was a flat out sociopath, he eventually evolves into a very mentally complex Well-Intentioned Extremist. Compare his perspective of humans at the beginning and end of his character arc: as just worthless food at first, and into deep respect and awe by the end.
- Arc Villain: Of the Chimera Ant arc. His status as the Big Bad is debatable however, as that title is better suited to Shaiapouf near the end and after his fight with Netero he loses all remaining traces of evil.
- Attack! Attack! Attack!: His strategy against Netero, to wear him down until he makes a mistake. It works.
- Awesomeness by Analysis: The ultimate aim of the above strategy. He knows that he can't beat Netero's sheer speed, so he uses his attacks to continually force Netero to bring out all his best moves so that he can analyze them and ultimately build up a way to reach Netero by exploiting the minuscule bias in Netero's moves.
- Badass Arm-Fold: Has a tendency to default to this when standing. And, can more than back the swagger up.
- Badass Boast: At least three.(To Netero) Defeat you without killing you? So like a bishop with a handicap. No matter, I'll checkmate you shortly.
- Bad Boss: Annoy him in the slightest and he will whip you with his tail, and if you are not durable enough, you die. Eventually subverted. He doesn't punish Welfin or Pouf despite the former's explicit renouncement of him as his king and the latter's outright treachery, and near the end of his life and Character Development, he tells Komugi that he was unworthy of the Royal Guard's loyalty and that he would like to thank them in the afterlife.
- Bald of Evil: Almost all the evolved Ants have hair, though Meruem is completely bald.
- Bait the Dog: Meruem's games with Komugi bring out his more human side, with him developing some respect for the Gungi prodigy. He goes so far as to tear off one of his arms as an apology for a dirty tactic. One night, he gives a speech to the Royal Guards about how human beings can be strong in more than one way, and mentions a young child he killed and how he stifled the child's potential...only to say he regrets nothing and can do anything he wants thanks to his overwhelming physical might. He then goes into his castle to kill Komugi but shows doubt over discarding her so easily, ends up rescuing her from a hawk, and tells her she is an honored guest at his castle.
- Battle Aura: Up to Eleven.
- Blind and the Beast: The Beast (the Chimera Ant King) to Komugi's Blind.
- Blood Knight: Not as much as many but he is definitely one. He didn't really want to fight Netero at first but later he starts to enjoy the fight.
- Born Winner: Despite being a newborn, Meruem is the most powerful Chimera Ant, and the most powerful character to be introduced in the series so far, as well as one of the most intelligent. Born as the ultimate biological weapon, his physical power is only matched by an unparalleled intellect. His overwhelming talent allows him to analyze and learn anything almost instantly, and hone his strategies to perfection.
- Break the Badass: Managed to scare Netero and Zeno just by walking.
- Bridal Carry: Does this to Komugi when she is severely injured, and later, asleep.
- Cannibalism Superpower: The more Nen based life forms he eats, the stronger he becomes. Note: he's already freakishly strong, so this is a really bad thing. After consuming Pouf and Youpi's bodies he transcends into the realm of a Physical God at least before his death.
- Catchphrase: "Don't make me repeat myself."
- Subverted Catch Phrase: "Let me repeat myself" to Palm near the end of the arc, showing how much he's changed.
- Character Development: He changes wildly throughout the arc. To go into detail: he begins as a sociopath, viewing all life (including his guards) as lower than him. After being with the Royal Guard for a while, he begins to appreciate their existence, and is respectful of them, but lets them know that they are replaceable in his eyes. After playing with Komugi, he begins to have an existential crisis about how everyone has potential to best him in any field, yet his raw strength trumps all- only for him to declare that this must mean he's better than everyone, because even if they beat him in a game he can still destroy them easily. It becomes clear, however, that this is just him convincing himself of his power, and he holds off of his original plan of killing Komugi because he wants to keep her around. After Komugi is injured, the King expresses incredible anger, and goes to fight Netero in an honorable duel. He states he now appreciates humanity as well, and despite still wanting to conquer the world he decides he will spare humanity for their efforts and their role in his creation. He also states he detests conflict, and will rule the world through diplomatic means- he even tries to negotiate with Netero. After he's caught in the Rose Bomb explosion, he loses his memory but keeps his Anti-Villain nature, respecting his Guard even more. After sparing Pouf (despite Pouf lying to him on multiple occasions) he realizes that he is poisoned, finds Komugi, and dies playing Gungi with her, finally content.
- Code of Honor: He slowly begins to develop one over the course of the arc. His pride as a powerful individual influences his code early on as he couldn't stand weakness nor tolerate any instance where he himself seemed weak. This manifested as never being able to accept victory unless his opponent was at their best because he didn't want an unfair advantage. Later he ripped off his own arm as an apology for trying to use a petty tactic to manipulate Komugi into losing; "Petty" in his eyes as, while using psychology was fine to psych out opponents, Komugi proved to have more resolve willing to bet her life on the game and realized she had more resolve and was taking the game more seriously than he was. Toward the end his code of honor developed into one based on the admiration he felt towards other exceptional individuals and felt that if he went back on his word or acted in a dishonorable way he would, to use Youpi's own words, feel like he "lost to them" or was less than them (them being the people he admired and the strength they demonstrated).
- Combo Platter Powers: After consuming Pouf and Youpi's bodies to survive the Rose Bomb he ends up having pseudo-precognition, lightspeed flash step, Youpi and Pouf's abilities in addition to his ability to grow stronger with devouring other Nen users and his flying brick set.
- Dark Messiah: Starts off as The Antichrist, but becomes this with Komugi's influence.
- Defeat Means Friendship: Sort of. He strikes up a friendship/UST with Komugi after getting his ass kicked in Gungi.
- Desperately Looking for a Purpose in Life: Has traits of this over time:Meruem: Who am I? Why am I here? A king with no name. A borrowed castle. My subjects are mindless drones. If this is the mandate of Heaven I have been given...I fear...I fear nothing...except the tedium that it will bring!!!
- Devour the Dragon: A rare non malicious version. After getting caught in the centre of Netero's Miniature Rose, Meruem is left on the verge of death. In order to save him, Pouf and Youpi willingly transform most of their bodies and Nen into energy and feed it to Meruem which restores him and gives him a boost to boot.
- Died in Your Arms Tonight: In Komugi's arms. Who joined him immediately afterward by the very act of holding Meruem in her arms.
- Double Consciousness: Stuck between the Ant and the human being.
- The Dreaded: The mere mention of his birth is what gets the leader of IGO to get back into fighting on the front lines. Up to Eleven when he briefly becomes a Physical God.
- Enfante Terrible: Kills his mother after telling her to shut up.
- Evil Laugh: FUHAHAHAHAHA.
- Face Death with Dignity: Dying hardly seems to matter to him, so focused is he on reuniting with his veritable Love Interest, Komugi.
- Fetus Terrible: Before his birth, everybody knew how dangerous he would be.
- Fights Like a Normal: He beats Netero without using Nen.
- Flying Brick: Initially lacked this, having to rely on Pouf for transport, but he later gains wings and teleportation after becoming a Physical God.
- Foil: To Gon, despite the two never interacting. The main theme of the Chimera Ant arc, as exmpelified in the lyrics to the ending song Hyori Ittai, is that good and evil are two sides of the same coin; the "monstrous" Ants and the "heroic" humans are capable of being both moral and amoral depending on the individual. Meruem's character arc turns him from one of the most heinous characters in the show to a rational, level-headed individual who greatly respects humans and gracefully accepts his own defeat, whereas Gon goes through the opposite journey, going from the All-Loving Hero we all know and love to a vengeful, dark individual who infamously threatened to kill an innocent human girl and ended the arc as a grotesque caricature of his former self, covered in the blood of his freshly-mauled nemesis and his own Broken Tears. Some fans have also noted that Gon's sitting posture while furiously waiting for Komugi to be healed is identical to Meruem's default sitting posture, along with some other visual parallels and contrasts, such as Meruem's increasingly soft and human expressions as opposed to Gon's increasingly deranged and hateful expressions.
- On a similar note, Netero is another potential Foil as the other representative of "humanity" as a whole, paralleling Meruem's representation of the Ants as a whole. Meruem did not want to fight Netero and would've preferred to negotiate a way to create a world that's an equal utopia, a proposition which Netero rejected. When Netero was defeated, Meruem explained that he is the apex of the entire Chimera Ant race and the culmination of their evolution, whereas Netero, while powerful, is ultimately just an individual. In response, Netero merely scoffed, and explained that he is not alone and that Meruem has no idea how far humanity's potential for evolution/malice can go. He was carrying inside him a crystallization of humanity's achievements: a horrifyingly cruel WMD, the past usage of which makes the Ants' antrocities look like child's play.
- The Force Is Strong with This One: His aura, after his rebirth, is so strong that it envelopes the entire castle, giving a massive Oh, Crap! moment to all those that sensed it. Knuckle says that they would need the military might of an entire nation to handle him.
- Genius Bruiser: Meruem has extraordinary intelligence, being able to learn and master nearly anything he comes across, such as board games. He then can apply this knowledge in his battle against Netero and eventually succeeds by doing so.
- Graceful Loser: He really didn't take his first losses against Komugi well, but after some consideration and introspection, ended up accepting his defeats easily.
- Hate Sink: He is initially presented as being heinous beyond belief, an arrogant megalomaniac who would trample over his own family, his comrades and innocent children just to establish his supremacy. The fact that he goes from this to being one of the most sympathetic characters in the arc is a testament to the enormous amount of Character Development he goes through.
- I Just Want to Be Normal: Before he dies.
- I'm a Humanitarian: To him, all creatures are prey. He would have also eaten Welfin if he had lied to him.
- Interspecies Romance: He (a chimera ant) and Komugi (a human).
- Jerkass: He told his mother to shut up moments before he was born. Not a minute after, he Tail slaps the heads off two of his subjects. The first was Peggy, who ran past him when he demanded food and then the other because he offered to clean Peggy's blood off Meruem's tail... which Meruem demanded Colt specifically to do first. Thank god he Took a Level in Kindness.
- Laser-Guided Amnesia: After Netero explodes on him, he temporarily loses his memories.
- Lightning Bruiser: He's virtually unstoppable on the attack, fast enough that Netero needs his highest-level technique just to stay a step ahead, and durable enough to simply tank Netero's attack over and over and over (etc) again until he finds its weakness.
- Love Redeems: A major part of his Character Development is him admitting his respect of other creatures, and the experience of having someone care for him as an equal, not a superior.
- Made of Iron: This saves him when fighting Netero, since at first he could not block and barely avoid Netero's attacks.
- Major Injury Underreaction: He ripped off his own arm without batting an eye.
- Meaningful Name: Meruem means Light and he later masters a light themed teleportation technique.
- The Napoleon: Shorter than all three of his guards and with a personality to match.
- Nice Job Fixing It, Villain!: By killing Peggy, he ended up causing Meleoreon to switch sides and perform a HeelFace Turn
- Nigh Invulnerable: He only just started to notice dull amounts of pain after getting hit a bunch of times by Netero. He was also able to take on Netero's most powerful move, the Zero Hand, which launches Netero's entire aura upon his opponent (aura so strong that simply being in the presence of it can feel like needles on the skin) and he only received cuts and bruises. It took a fucking atomic bomb to bring him to near death. Near!
- Noble Demon: He starts out as a monster who only lives to eat, kill and conquer, and doesn't feel a sliver of care for anyone except for himself. After bonding with Komugi, he starts respecting his guards and accepting the value of other lifeforms.
- No Name Given: He does, but he left his mother to die before finding out, and honestly probably would not have cared at that point anyway. Once his Character Development kicks in, this bothers him a great deal, to the point that Netero is able to goad Meruem into fighting by telling the king he knows his true name.
- O.O.C. Is Serious Business: After telling Pitou to heal Komugi, he calmly adds "I'm counting on you", which is a massive departure from his usual manner of barking demands at his underlings. Pitou was reduced to tears in response and treated healing Komugi as the most important task in their life.
- Oh, Crap!: After seeing Netero's smilling face right before he set off the Miniature Rose, the King- as per the narrator's words- experiences fear for the first time in his life.
- One-Man Army: Especially after becoming a Physical God.
- Physical God: After Netero's supposedly failed attempt to kill him via nuclear bomb, Meruem's power ascended to near omnipotent levels, being able to zoom in onto a location kilometers away in seconds.
- Picky People Eater: His meal of choice is the brain of a Nen user.
- Pride: Has a large ego fitting of a Physical God, he tries to later use that ego for well-intentioned purposes after some significant Character Development.
- Psychic Link: With Pouf and Youpi, after his fight against Netero. Pouf continues to forget about it, and this brings about his downfall as Pouf attempts to plot against his wishes.
- Psychotic Smirk: Smiles like that from time to time, but he mellows out of it.
- Puny Humans: His initial thought about them, but Komugi and Netero changed his view on them.
- Purple Is Powerful: His aura; fitting for the most powerful character in the series.
- Red Eyes, Take Warning: For a moment in episode 132 as well as a few in several episodes prior.
- Royals Who Actually Do Something: Technically it's an insect hierarchy term, but he fulfills the requirements, especially with the Physical God traits.
- Reality Ensues: Upon being subjected to the explosion of the Miniature Rose Netero kept inside himself, Meruem seems to recover relatively well thanks to the healing given to him by Youpi and Pouf. Unfortunately for him, one of the reasons nuclear devices are so deadly is radiation- Meruem dies from radiation poisoning not long after he returns to the palace, not realizing the deadliness of it. This also causes the deaths of Youpi, Pouf, and Komugi by proxy, as they all have prolonged contact with the king and are thus contaminated as well.
- Self-Harm: Rips off his own arm as an apology to Komugi for trying to use a "petty tactic" to unnerve her.
- Self-Made Orphan: He killed his own mother.
- Smart People Play Chess: And Gungi, and Go.
- Smug Smiler: The master of this and one of his first expressions.
- Smug Super: Even with his Well-Intentioned Extremist goals, he still viewed his power highly.
- Social Darwinist: He believes that the strong should rule the weak. When Shaiapouf tells him that in human society individuals without intelligence and talent can nonetheless be in positions of power due to bloodline and connections, he is truly perplexed and says that it defies logic.
- Spanner in the Works: He is this for himself. His failed attempts to manipulate Komugi results in him ripping off his own arm, causing Neferpitou to drop their shield while they repair him, allowing Knov to infiltrate the palace and giving the Hunters easy access.
- Spider-Sense: After all his losses against Komugi, he developed these.
- Stay with Me Until I Die: To Komugi. And by doing this, she joins him shortly afterward.
- The Stoic: You could count off the number of things that could make him visibly react with five fingers. Before you do, ripping off his own arm isn't one of them.
- Story-Breaker Power: Photon. He transforms his own En into light, which allows him to not only sense others within his vicinity, but also teleport to their location instantly. And it just so happens that Meruem has vast En, meaning he can blanket an entire city and possibly even well beyond that with his aura, locate a target in an instant, and attack them without warning. Had he survived, he could have easily conquered the entire 'known' world with this power alone.
- Superpower Lottery: The most powerful character in the series by far. He is born as the ultimate biological weapon, able to increase his own aura by eating other nen users, giving him vast amounts of nen. After eating Pouf and Youpi's bodies, his aura reserves are so great that even the Royal Guards admit the he seems invincible.
- Super Speed: He can move at extremely fast speed when fighting Netero, despite Netero landing multiple strikes upon him (he could travel at speeds approaching mach 1). After absorbing Menthuthuyoupi and Shaiapouf, he gained the ability to fly, allowing him to move at super-sonic speed in mere seconds.
- Super Strength: Meruem's physical strength is inconceivable as he was able to use only one powerful strike with his tail to kill several other Chimera Ants. He also was able to rip off Netero's left arm and right leg easily. He even injured all three of the Royal Guards with his tail strikes, however they weren't serious injuries (However it should be noted that he didn't use anywhere near his full strength).
- Tail Slap: Really fond of doing this when one of his subordinates make him angry.
- Take Over the World: Born to stand at the top of this world.
- A Taste of Defeat: His first loss against Komugi.
- Teleportation: His ability, Photon which allows him to turn his En into light and move instantly to any spot it covers.
- Together in Death: With Komugi.
- Took a Level in Kindness: Meruem started off as a callous, sociopathic jerk who was a Bad Boss to his minions and regarded everyone beneath him as tools or food. When he rescues Komugi from a hawk, her sheer helplessness, talent, and gratitude shake Meruem to his core. His first conscious act of kindness is to make Komugi his honored guest, and from there, his respect for others grows and extends to humanity itself.
- Too Powerful to Live: At the point before his death, he was the strongest character in existence, and since there wasn't any convincible way for him to be defeated, he died from radiation poisoning.
- Tranquil Fury: When Netero and Zeno (accidentally) hurt Komugi. He was not happy at all.
- Ultimate Life Form: The ultimate Chimera Ant. Taken Up to Eleven once he gets a power boost from Netero's failed (or thought to have failed) attempt to kill him, rising him to Physical God levels of power, and was at that moment, the strongest character in the series.
- Unskilled, but Strong: At least when it comes to fighting and using nen. While he is a genius and can use all of the basics of nen, he never went through any kind of conditioning or formal training nor did he have extensive experience using nen. In the one real fight he ever had against an experienced nen user (Netero who was once considered the strongest in the world no less) he had to resort to "let him hit me until I find and opening" because he coudln't keep up with Netero's speed at all. If he wasn't such a physical monster or had Super Toughness as one of his powers, he would have stood no chance against Netero.
- There are also other nen abilities which are subtle and can bypass strength alltogether. While not explored in depth, Knov could create portals and use his ability to make a Portal Cut on one of the ant soldiers. If this was a One-Hit Kill then all they would have to do it set up the king for it and then bisect him. As Hisoka once said, "Nen is deep and has many facets". Power isn't the deciding factor in a nen fight.
- Utopia Justifies the Means: After observing some of humanity's structural flaws (pigs being in positions of power while innocent children starve to death) and after interacting with Komugi, he adjusts his ambitions from a hostile takeover of humanity to creating a utopia where "the concept of inequality doesn't exist" and humans could coexist with Chimera Ants to some extent. He admits that he will at first use terror to achieve that goal, but the end result will be a far better world to live in for both humans and Ants. Netero was not fully convinced, and he wasn't about to give up his mission either way.
- Victory Is Boring: Which is why he found playing with Komugi so refreshing.
- Villain Protagonist: Once he's introduced, most of the Chimera Ant arc seems to focus on him and his Royal Guard. Gon and the other Hunters become less and less prominent in the story's trajectory and seem more like supporting characters of his personal story.
- Visual Development: As Komugi opened his heart, he noticeably became more human and gentler in appearance.
- Well-Intentioned Extremist: After meeting Komugi, Meruem's motivations change from, "turn humanity into mindless livestock for me to devour" into "protect the weak and insure the abolishment of inequality". He actually brings up several good points in his argument which are so effective Netero has to steel himself lest he be turned over to the King's side.
- What Is This Feeling?: At first, he didn't understand the reason he felt the urge to protect something weak like Komugi.
- When He Smiles: When he finds Komugi after getting his memories back.
- Would Hurt a Child: Kills a little girl and her family with no hesitation. They are just food to him, after all.
- Worthy Opponent: While waiting for his plans to proceed, Meruem entertains himeself by challenging the country's best board game champions and defeats them all on his first try, only needing to read the rules before he bests them at their own game. But not once over dozens of games of gungi does Meruem ever defeat Komugi. In time, he comes to admire, and eventually fall for her, not just for her skill, but for her spirit- the commitment to play each game as if her life depended on it.
- During their battle, he also comes to respect Netero as a truly worthy human.
- Your Days Are Numbered: Because of The Rose's poison.

The first of the Royal Guards to be introduced, direct assistant to the king and an incredible fighter in their own right. Neferpitou, called Pitou for short, is an extremely feminine cat person. Like a cat, they love to toy with their victims and is somewhat psychotic. After killing Kite, Neferpitou uses him as a training toy. Seeing his dead mentor like this creates a deep grudge in Gon. After Komugi becomes injured in one of Zeno's attacks, the King assigns Neferpitou to heal her. When Gon arrives at the East Gorteau palace, Neferpitou had not yet finished healing Komugi, but Gon allows them to finish first on the condition that Pitou return Kite to normal. The two then duel; Gon ultimately kills off Neferpitou. Of the three Royal Guards, they were the only one to retain their composure despite being the most psychotic under normal circumstances.
Neferpitou is a Specialist. Their Nen ability comes in two varieties: "Doctor Blythe", a strange, horrific-looking nurse with the ability to heal injuries, and a clown-shaped puppetmaster that turns people into People Puppets. Said puppets can use their nen abilities, if they had them. During their fight with Gon, Pitou displays a third ability, "Terpischora", a deranged-looking puppeteer ballerina who can enhance their physical abilities.
- Ambiguous Gender:
- Pitou's gender isn't confirmed. They use "boku", a masculine pronoun, (albeit also used fairly commonly by tomboys and some young girls) contrasted with a curvy body that is especially feminine in the anime. Given the presence of transgender and gender-nonconforming characters elsewhere in the series, speculation as to where Pitou falls between "male" and "Bokukko" is going to remain speculation. Additional Material and Games currently go for female.
- The narration in the Chimera Ant arc is extremely detailed, but Pitou is never referred to by any pronoun. It's not even clear if they're non-binary.
- Apologetic Attacker: Apologizes to Gon before they explain they have to kill him for the King's sake.
- Arch-Enemy: Gon considers Pitou to be his.
- Art Evolution: Pitou starts off in the manga with an Ax-Crazy yet blank look in their eyes for a more realistic face, and a rather large sash across their standard clothes, somewhat resembling a violent and crazed feline in a Humanoid Abomination form. As the Chimera Ant arc goes on, however, Pitou's design ditches the sash post-Kite, gradually becomes more cute, wide-eyed, leaner and shorter, and falls more in line with the series' feminine designs to fit their Character Development. The anime opted to use the later design from the start for more consistency, and with no sash in sight, but still has their facial and eye expressions shift for a broader emotional spectrum with time to match the same general idea.
- Awesomeness by Analysis: In the anime, they learn how to operate a brain by reading books.
- Ax-Crazy: Though they have a relatively small on-panel body count, they control a large number of corpses and describe killing with glee (saying they wanted to kill Kite over and over).
- Badass Adorable: Admit it. Even being horrible can be adorable, because cat.
- Badass Bookworm: Teaching yourself advanced neurobiology to then incorporate it into a powerful attack-defense mechanism with Nen? Yeah: this counts.
- Blood Knight: Very much loves a good fight. Poor Kite.
- Born Winner: Born with an Nen mastery and an aura stronger than Netero, they even kill Kite with no training or special ability. It's valid for all the Royal Guards and even more for The King.
- Breakout Villain: Since their appearance, they've easily become one of the most popular characters in the series, appearing in fan arts and other media.
- Catchphrase: "Now I understand", though it could also be translated as "Meow I understand", due to them making a cat pun in the original Japanese whenever they say it. The dub runs with the pun.
- Cat Girl: Basically Pitou looks like a human cat with cat ears, a tail, and bestial hands. Their gender is officially unknown, but Pitou appear more feminine in their anime adaption with a consistent bust, differing from their slightly ambiguous manga appearance.
- Cats Are Mean: Played with. They were very loyal to the king and were always ready to give their life for him, but against humans and lesser Chimeras, they cranked this trope Up to Eleven.
- Character Development: Goes from a murderous lunatic to a protective figure for Komugi. Despite being easily able to kill Gon where they stand (even with Gon and Killua's Training from Hell), they actually honor Gon's wishes and breaks the news to him about Kite face to face out of respect. They even seem to sympathize with him, but by then it's too little, too late.
- Climax Boss: Pitou is this for Gon in the Chimera Ant arc, since Gon and Meruem never meet.
- Cloud Cuckoo Lander: It's even lampshaded by Pouf.
- Combat Medic: Played with, since they can't fight while using their healing ability.
- Creepy Ballet: Terpischora evokes this, as they appear like a deranged yet graceful puppeteer-ballerina whom Pitou commands to make them "dance past [their] limits".
- Cruel and Unusual Death: Punched incredibly high into the sky with a hit that breaks ''almost all of their bones and mulches their internal organs'', is then hit with a second one that completely caves in their skull, and is finally put down when Gon smashes their head into nothingness. They come back as a zombie, only to be blown into oblivion by Gon's Super Mode self-destructing.
- Determinator: Continues fighting even after Gon destroys their head.
- Death by Irony: Pitou is the first character to take Meruem's Tail Slap without getting their head splattered, earning Meruem's praise for their durability. Gon's Roaring Rampage of Revenge ages him up to his peak, where Pitou observes that he's on par with Meruem, and they end up dying from... getting their head pulverized.
- Death by Pragmatism: Pitou fully acknowledges that Gon is such a serious threat that, should his potential get the opportunity to grow, he might even be a threat to Mereum. With some exploitation by Pouf to stir Pitou into killing Gon, this choice of action would've been easy enough - had Gon not been so broken that he willingly sacrificed all of that potential just to kill Pitou. Thus the Ant's pragmatism ended up causing their own demise.
- Death Glare: In their first meeting with Gon and Killua
- Does This Remind You of Anything?: Pitou's speech to Kite's corpse about how much fun fighting was sounds quite a bit like Pitou is describing something else...
- The Dragon: To the king, along with Youpi. Pouf on the other hand is complicated to say the least.
- Dramatic Irony: They're also the first of the Royal Guard to die, not because of the radiation that kills the other two and the King, but because their attempts to resolve an equivalent deal of reviving Kite for Gon sparing Komugi fell through and Pitou was going to kill Gon. Gon's response of sacrificing all of his potential just to murder Pitou as brutally and violently as possible succeeds, killing Pitou in a downright horrific fashion and as far away from the King they swore to protect as possible - and because Kite was reincarnated as a Chimera Ant, Pitou's death by Gon's rage was ultimately meaningless, a mere aside note that affects little else for the rest of the arc yet cripples Gon's Nen for life.
- The Dreaded: Has an insanely malicious aura that can paralyze even experienced Hunters in their tracks. Killua described it as being even worse than Hisoka or Illumi's auras, and the invasion squad could feel it even when Pitou was blown away from the palace by Netero.
- Evil Puppeteer: One of the major antagonists throughout the Chimera Ant arc, Pitou displays the ability to create People Puppets out of humans the Ants capture.
- Fighter, Mage, Thief: The thief to Pouf's mage and Youpi's fighter.
- Game Face: This◊.
- Hero Killer: Personally offs Kite, and interrogates (read: lobotomizes) Pokkle before disposing of him. The former sets off Gon personally, while no one learns about the latter because Pokkle's entire squad also bit the dust to Soldier Ants.
- I'm Crying, but I Don't Know Why: They didn't understand why they were crying after Meruem finally offered them his trust, but they were truthfully happy.
- Impaled with Extreme Prejudice: On top of every thing else they endure after having their head caved in Gon proceeds to impale Pitou's reanimated course with his severed arm before smashing them point blank with his most powerful Jajanken to finish them off.
- In a Single Bound: Their legs are incredibly powerful, they are able to cover very long distance in one leap. They made a huge leap to slice Kite's arm and to attack Netero.
- In Love with Your Carnage: After killing Kite Pitou kept his body and mentions how much fun they had fighting him describing it as a "dream like moment." In fact the entire reason Pitou develops their People Puppet ability is so they can bring Kite back and experience that moment over and over again.
- In-Series Nickname: Pitou.
- Irony: As the one that killed Kite, personally setting off Gon on being hellbent for vengeance as well as being considered potentially strong enough to beat even Netero, much of the planning to kill the King focuses on separating Pitou from Meruem with everyone absolutely paranoid of dealing with them on any level; indeed, Pitou could've killed Gon and Killua effortlessly in each of their encounters. In the end, Pitou trying to save Komugi's life from a wound inflicted in the initial crossfire means they are completely removed from the rest of the main battle without a fight.
- Killed Off for Real: They made a promise to go with Gon to Peijin to restore Kite, but once they reached the area, Pitou affirms that the task is impossible and subsequently prepares to kill Gon. In a rage, Gon forcibly ages his body through expending nearly all of his natural potential and kills Pitou with the temporary Nen-boost. Postmortem, Pitou's corpse is manipulated by the remnants of their Nen ability until it is destroyed by Gon.
- Knight of Cerebus: The show always had a dark side, but none of it sent Gon off the edge before Pitou came along.
- Losing a Shoe in the Struggle: When Pitou was on the ends of a downright grisly No-Holds-Barred Beatdown from Gon, it knocked off one of his shoes at some point, then the other, leaving them with just a pair of socks covered in their own blood.
- Mad Scientist: Has a lair filled with equipment and works with Pouf to revive and turn Palm into a Super Soldier Half-Human Hybrid.
- The Medic: Their "Doctor Blythe" (a giant doll), that can used to surgically treat damaged areas of the body. It is equipped with countless medical tools that can be used to provide first aid as well as perform major surgeries.
- Muscles Are Meaningless: Skinny as a twig, they can rip off human limbs and heads without strain and with just one hand.
- The Nose Knows: Neferpitou was able to smell Pokkle while the latter was hiding in a massive pile of bones.
- Ooc Is Serious Business: Drops their "playful catgirl" attitude upon being hit by Netero's attack and realizing that the invasion squad might be an actual threat to the King and that Komugi's life is in danger. They stay that way until the end of the arc.
- Off with His Head!: A particularly scary example in which Pitou's head is not cut off, per se, but beaten so badly that it is pulped away until it is outright GONE.
- Oh, Crap!: Has a spectacularly terrified reaction that realizes just how screwed they are once Gon gives in to his rage and enters his Super Mode. Further bolstered when he immediately demonstrates that he outspeeds Pitou with no effort.
- People Puppets: After emitting their aura in the shape of a clownesque puppeteer, Neferpitou can attach it to a body (alive or dead) to exercise complete control over the body in question. The body can not only move it, but also make it speak and even have it use Nen regardless of whether the owner of the body was a Nen user. If the corpse is indeed that of a Nen user, Neferpitou can have it use its Nen abilities. The number of bodies Neferpitou can control at the same time is unknown.
- They can use this power even on themselves. Their Terpsichora takes the form of a monstrous ballerina with strings connecting its fingertips to Neferpitou's body like a marionette. It is a combat-oriented ability that manipulates Neferpitou. Even when Neferpitou's head was crushed, the ability remained active out of their loyalty to the King, becoming stronger after death, enabling them to mutilate Gon's arm.
- Perpetual Smiler: Has various smiles to use, but rarely manages any other expression.
- Pronoun Trouble: Not as much a problem in Japanese, but definitely plagues English translations.
- Rasputinian Death: Gon beats Pitou so badly that their head is destroyed, then the rest of them gets smashed to bits while reanimated by the force of their own Nen.
- Red Eyes, Take Warning: In the anime, their eyes are usually depicted as a maroonish red in the dark parts of the iris and gold in the light parts, for a "red" look overall, but in some shots from a sharp angle are all gold or all maroon/red. It might be an attempt at representing iridescence on a limited animation budget.
- The Reliable One: In spite of not quite looking the part and being a cold-blooded killer and torturer, Pitou is both the most reliable and resourceful of the Royal Guards, and is the only one of the three that actually adheres to their Kings wishes behind his back and has no restraints about it.
- Scarf Of Asskicking: Had one during their first appearance in the manga.
- A Storm Is Coming: Said this before the Palace Invasion.
- Super Mode: By conjuring an eerie Nen creature to control them. According to the narrator, "Puppet Master's Serenity" is their strongest ability, though Gon promptly defeats it with his Dangerous Forbidden Technique.
- Super Senses: Their sense are over-developed. Pitou was able to spot Kite, Gon and Killua, who were around more than half a kilometer away with their sight. And was also able to hear cell phone that was on low volume with their extremely accurate hearing, while Gon, who has a similar ability, could not hear anything.
- Undying Loyalty: Unlike Pouf, they never even consider questioning the King's judgment and will follow his orders to the letter. Their loyalty even inadvertently humanizes the King the most. Their loyalty is so strong that their nen can activate on its own after their death, to treat their own corpse as a puppet that will fight to protect the King.
- Verbal Tic: "Nyah". Drops it when things start getting serious, though.
- Worthy Opponent: They appear to develop a genuine respect for Gon after he keeps his word to allow them to heal Komugi, to the extent that they apologize for being forced to kill him.

A bishounen man who is mostly human and butterfly and the second of the Royal Guards to be introduced. Called Pouf for short. His defining characteristic is his obsession with making sure the King is safe and to follow his every order. Shaiapouf becomes incredibly anxious if he's separated from the King or becomes unable to finish a command from him. He cries waterfalls and plays the violin to relieve this frustration, making him something of a comic relief of the bunch. After gathering everyone in East Gorteau over to in front of the palace, Shaiapouf hypnotizes the crowd to keep them organized and takes on Morel in one of the towers. Morel takes advantage of Shaiapouf's fanaticism towards the king and traps the both of them in a smoke wall he is unable to force through. However, he finds an opening and escapes with his other nen ability, which is to split himself into any number of smaller versions of himself; these fragments resemble a Puni Plush version of himself. He meets up with Menthuthuyoupi as he flees from Morel, finds the King, and allows the King to absorb himself into him, adding Shaiapouf's strength to his own. He then takes advantage of the king's bout of amnesia to try to kill Komugi and/or manipulate him away from the King, which he nearly succeeds doing if not for Welfin's interjection. He dies of radiation poisoning soon after Komugi's existence is remembered by the King.
Shaipouf mainly uses his Nen in two ways: Spiritual Message, in which he uses his scales to assess someone's aura and mental condition, and Beelzebub, where he breaks his body up into Fun Size versions of him that can act as spies or form clones. He also displays the ability to create human-Chimera Ant hybrids, and control his face and voice to look like someone he's met.
- Ax-Crazy: His Yandere obsession with the King and killing Komugi makes him the most unstable of the Royal Guard, despite being the most rational in normal circumstances.
- Badass Cape: When his wings are not deployed they look like a cape.
- Beastman: A butterfly man.
- Big Bad: He takes up this role during the period of time the king lacks his memories.
- Bishōnen: Despite this, he's easily the most amoral of the Royal Guard, lacking the honor Youpi feels for his opponents or the understanding Pitou has for the King.
- Broken Tears: Up to Eleven. He constantly cries, and eventually he manages to get Youpi crying.
- Catchphrase: "Sore dake no koto" which means "that's all there is to it".
- Character Development: Started out as one of the more rational members of the Royal Guards but by the end of the Chimera Ants arc, he ended up being the most unstable one of them all.
- Cultured Badass: Exudes this and can back it up in a number of ways — he's a well-dressed violinist with an operatic "cape" (actually his wings). However... there's an emotional thug inside the violin player.
- Despair Event Horizon: A particularly unsympathetic example. After witnessing Meruem remember Komugi and realizing through their mental link just how much he cares for her, Pouf loses all hope and asks Meruem to execute him right then and there. To his further dismay, Meruem refuses. As the final twist of the knife, when Pouf is lying down in a Pose of Supplication, he overhears Meruem telling Welfin that he "wishes he can live as a human" and winces at the phrase. Devastated beyond repair, Pouf remains at that exact spot until his poison-induced death puts him out of his misery.
- Drama Queen: There are parade and runway queens who drama less.
- The Dreaded: Just looking at his aura is enough to terrify even the most experienced Hunters. Knov got caught in it during a scouting mission, and it was enough to turn his hair white and horrify him into a Heroic BSoD.
- Elegant Classical Musician: Violin in his case.
- The Empath: In his fight against Morel he uses his nen ability Spiritual Message this way.
- Evil Genius: When he uses his energy for plotting rather than sheer melodrama, he's scarily good.
- Face of an Angel, Mind of a Demon: Despite being Bishōnen, he's easily the most amoral of the Royal Guard, and especially since his more moral associates are an Ax-Crazy Cat Boy.. Girl... and a Hair-Trigger Temper brute. One particular facial expression he makes is particularly notable, as it fully illustrates that his human appearance is a mask that barely hides what he really is on the inside - a vicious, ugly beast.
- Fighter, Mage, Thief: The mage to Youpi's fighter and Pitou's thief.
- Glamor Failure: While normally Bishōnen, when the King was badly wounded, one of his clones reveals his true hideous nature for a moment.◊
- Green-Eyed Monster: Let's just say that a lot of King/Komugi shippers have it out for him. To say nothing of how many pages Togashi devotes to him gushing over the king.
- Hate Sink: Unlike Meureum, Pitou, and Youpi, he is presented in a very negative light as a Yandere who is deadset on killing the King's Morality Pet.
- Flight: Naturally.
- In-Series Nickname: Pouf.
- It Is Pronounced Tro Pay: The "ai" in "Shaia" is not pronounced at all, instead replaced with a "wh" sound, thus the pronunciation is more along the lines of "Shauapouf".
- Kick the Dog: He ended up suggesting a Brainwashed and Crazy Palm to kill Killua when the ex-assassin was in the middle of an emotional breakdown.
- Manipulative Bastard: To the king and everyone
- Me's a Crowd: Pouf's Nen ability Beelzebub allows him to split his body into tiny sized pieces that allow him to scatter into multiple areas and scout ahead. The downside is that these smaller forms are much weaker then when he is complete and, if destroyed, Pouf losses a portion of his body and power.
- Mind Control: One of his Nen abilites, Spiritual Message, which allows Pouf to hypnotise anyone that is hit by his scales. He uses this to put the inhabitants of East Gorteau into a trance in so that they wont run away from being feed/converted into ants.
- Murder the Hypotenuse: Makes it very clear he intends to kill Komugi, because she's his Morality Chain, seeing her as an obstacle in the kings path to greatness.
- And once the King gets Easy Amnesia, he immediately tries to jump at the idea of killing her while he's unable to remember anything.
- Mood-Swinger: Goes from cold-hearted plotting to insane laughter to Inelegant Blubbering in the span of minutes.
- Never My Fault: He did nothing wrong. It was all for the sake of The King!
- Nightmare Face: This.◊
- Nonstandard Character Design: Chibi-Pouf. His ability to strategize is not lessened at all, still making him a threat despite his adorable appearance. He looks like APR!
- Only Sane Man: Subverted. He thinks he is, but he's easily the most monstrous of the Royal Guard in terms of amorality.
- Pretty Butterfly: Subverted to hell and back. He's a butterfly man who may look pretty, but his personality is anything but.
- Psychic Link: With Meruem and Youpi.
- "Psycho" Strings: Easily the most pretentious yet unhinged of the Royal Guard; Pouf is usually seen playing the violin and his theme contains a lot of frantic strings.
- Psycho Supporter Becoming more Yandere towards the King as time goes on.
- Psychotic Smirk: Once he starts going off the deep end, he starts making facial expressions that would make Light Yagami proud.
- The Reliable One: When Pitou and Youpi don't know what to do they always listen to him. But when Komugi is involved, this is heavily subverted.
- Say My Name: Your majesty!. This is not a name but it counts.
- Self-Deprecation His extreme loyalty causes him to cry buckets and play the violin whenever he feels like he betrayed the king, which is often.
- Sleep-Mode Size: He can split into multiple tiny, adorable clones of himself.
- Super Empowering: Spiritual Message permits him to give a Nen ability who will suit perfectly to anyone. He can also completely change their ability.
- Superpower Lottery: Able to manipulate an entire population of people to do his bidding and clone himself endlessly.
- Tears of Joy: After being complimented by Meruem while feeding him.
- Token Evil Teammate: Easily the most amoral royal guard of the three.
- Undignified Death: Collapses from the Miniature Rose poisoning in the middle of the brainwashed crowds he personally subdued, and Dies Wide Shut with an expression of despair. Unlike Youpi, whose death is recounted in detail by Welfin as a horrifying reveal for the effects of the poison, Pouf's is off-screen and not even given the dignity of a final speech or dramatic scene. Arguably a deserving fate for one of the most genuinely antagonistic characters in the whole arc.
- Undying Loyalty: Deconstructed very much as his loyalty to the King seems to be out Blind Obedience to the system of the Chimera Ants' hierarchy than true loyalty of his colleagues, which gives him the justification to Murder the Hypotenuse in order to get things back on track despite realizing how much this would make the king hate him.
- Unknown Rival: Rightly views Komugi as an impediment to the King taking his place at atop of the planet's food chain and desires nothing more than to kill her. Komugi's completely oblivious to all of this.
- Unwitting Instigator of Doom: In his plans to kill Komugi, Pouf intentionally tricks Pitou into thinking that she had been rescued from the Hunter attack team when she very much wasn't. This results in Pitou trying to fight Gon after they realize Kite was dead, and Gon pulling out a Super Mode that gets Pitou maimed and slaughtered for their troubles. Though to be fair to Pouf, he fully expected the opposite result, and while he considers it as a possibility, he never learns the result.
- Yandere: Is fanatically devoted to his ideal of what the King should be to the point of trying to change the King as he sees fit by lying and trying to kill Komugi, though the King obviously cares for her.

The third and last of the Royal Guards to be introduced, Menthuthuyoupi, or Youpi for short, is mostly human and shark. He is the Dumb Muscle of the bunch and considerably less intelligent than Pitou or Pouf. Nevertheless, the sheer force of his attacks mor than makes up for his ineptitude at strategization. He doesn't do much until the East Gorteau palace comes under direct attack, where he stands in a room getting bored. Knuckle, Meleoron, and Killua takes him on and attempt to kill him via attrition and Knuckle's ability. After a long fight, Youpi instead chooses to just go straight to the King. He meets up with Shaiapouf on his way, finds the King, and allows the King to absorb himself into him, adding Menthuthuyoupi's strength to his own but turning him into a chibi much like Pouf. He's soon accosted by Welfin, but he dies from radiation poisoning before Welfin can even touch him.
Youpi displays two main Nen abilities: shapeshifting, and rage-induced strength. The more frustrated and exasperated at his foes he becomes, the stronger and bulkier he gets. He gets so big and bulky that he unintentionally shifts forms once more into a centaur-like creature with his face on the side.
- Amazing Technicolor Population: He has red skin in the 2011 anime.
- Angst Nuke: His Rage Blast.
- Badass Baritone: It's a given considering his voice actor.
- The Berserker: Youpi harnesses his pure rage in battle to power himself up and transform his body into grotesque shapes to make himself stronger. Eventually he hones his rage and becomes able to fight while keeping a clear head thus averting this trope.
- Body Horror: He can transform his body, but what he does transform into isn't pretty
- Born Winner: Since he gets Voluntary Shapeshifting based on Wrath Up to Eleven, he's the physical strongest aside from the King
- Borrowed Catchphrase: Lampshaded by him upon borrowing Pitou's.
- The Brute: Relies on brute strength, but gets smarter with Character Development.
- Character Development: Goes from The Brute full of Hair-Trigger Temper to a Genius Bruiser who prioritizes the King's safety over a fight. A lot of this development happens over the course of one battle.
- Combat Tentacles: One of his transformations.
- Deadly Nosebleed: While dying from the Red rose.
- Dumb Muscle: Until the raid on the palace, Youpi acts as muscle for the Ants and leaves the thinking to Pitou and Pouf. It is later shown that he wasn't really dumb at all, but rather had never met an opponent he couldn't easily beat into oblivion.
- Evolution Power-Up: When he calms down, he becomes a centaurian being.
- Eyes Do Not Belong There: In one of his transformations, he sprouts eyes all over his body to keep track of his foes.
- Fighter, Mage, Thief: The fighter to Pouf's mage and Pitou's thief.
- Fun Size: After feeding his body to the King in order to revive him, Youpi shrinks to a winged chibi form only a bit bigger than Pouf's clones.
- Game Face: Abandons his humanoid form in favor of one more suited to intense combat when he battles the Extermination Team.
- Hair-Trigger Temper: He gets stronger the angrier he gets, but eventually masters it.
- Half-Human Hybrid: Averted unlike most of the ants Youpi doesn't have any human DNA in his system instead being a hybrid of various Magical Beasts. The narration notes that this means he's not concerned by his own existential identity and can just fight with raw animal instinct.
- Ignored Epiphany: After his fight with Morel and Knuckle, Youpi's opinions on humans begins to turn around and he finds himself respecting them for their tenacity. But then Meruem almost dies in the Miniature Rose explosion and Youpi rejects humanity once more.
- Incurable Cough of Death: He coughed frequently and died after saving Meruem. It's because he was caught in the radiation of the Rose.
- In-Series Nickname: Youpi.
- It Is Pronounced Tro Pay: The "Menthuthu" part of his name is pronounced similarly to French, making it sound more along the lines of "Montutuyoupi".
- Lovecraftian Superpower: He can transform his body into very eldritch shapes.
- Multi-Armed and Dangerous: One of his transformations.
- Noble Demon: Spares Knuckle, Morel, Meleoron and Shoot because he respects them as fighters.
- Nonhuman Humanoid Hybrid: Even though he looks quite a bit like a human being, he hasn't got a trace of human DNA inside him.
- Only Sane Man: Surprisingly, he turned out to be the sanest Royal Guard.
- Our Centaurs Are Different: Becomes this once he calms down enough to master his rage.
- Person of Mass Destruction: Especially his Rage Mode which causes a huge explosion with each hit.
- Pragmatic Villainy: Youpi agrees with Pouf that Komugi could potentially be a problem for the King and eventually goes along with Pouf's plan to murder her when Meruem loses his memories. However unlike Pouf whose Driven by Envy Youpi does so because he genuinely believes that Komugi could potentially weaken Meruem if they don't do something about it.
- Power Degeneration: He willfully gives some parts of his body to Meruem in order to heal him.
- Psychic Link: With Meruem and Pouf.
- Red Eyes, Take Warning: Once the Invasion Squad breaks into the palace Youpi stops thinking and switches into animalistic attacking which is represented by his eyes turning red.
- Rubber Man: Another extension of his shape-shifting abilities.
- Screaming Warrior: Prior to his Character Development.
- Sleep-Mode Size: After feeding most of himself to the king.
- Tentacled Terror: One of his methods of attack.
- Tranquil Fury: The culminant point of his Character Development.
- Undignified Death: Collapses from exposure to the Miniature Rose poisoning, right when he was about to tear Welfin a new one. His Sleep-Mode Size corpse is promptly left there, and while Pouf and Meruem question Welfin about it, he's forgotten fairly quickly as anything other than a warning for what's soon to come for Pouf and Meruem.
- Undying Loyalty: To the King, which he realizes is much important than lashing out angrily all the time.
- Unskilled, but Strong: He doesn't know how Nen works but he is still able to beat Knuckle, Shoot and Morel without problem.
- Vocal Dissonance: Youpi continues to speak in his gruff deep voice even after being reduced into Sleep-Mode Size.
- Voluntary Shapeshifting: His Nen power.
- Worthy Opponent: Considers Knuckle and Morel to be this and refrains from killing them because of it.
- Wrath: Weaponized.
- You Shall Not Pass!: "I am a shield. I protect the King with my body".
Meleoron / Jail
Voiced by: Nobuo Tobita (Japanese), Bill Rogers (English)
A human-chameleon hybrid and one of the former commanders. He served loyally under the Queen but dislikes the King and decides to join up with Gon and the others to help bring him down.
He has little combat ability on his own, but his Nen ability allows him and anyone he's touching to turn invisible. Not just visibly either, but from all five senses, plus total undetectable Nen cloaking. However, he can only do this while holding his breath. He helps his allies gather information about the King and the Royal Guards, then helps Knuckle and Killua fight Menthuthuyoupi by making the two of them appear to teleport around. He is currently hurt but not dead.
- Defector from Decadence: From the Chimera King forces.
- Half-Human Hybrid: A half chameleon, half human hybrid. He even has the power that comes with being one.
- HeelFace Turn: After seeing Gon's power, he decides its better to side with him than to be his enemy.
- Invisibility: Since he is a chameleon, he can turn invisible.
- The Nondescript: He uses this as an example to explain his ability to Gon. His power is this Up to Eleven.
- Only Sane Man: He is shocked that Gon isn't the least distrusting of him, for understandable reasons.
- Perception Filter: His second Nen ability lets him erase himself from all of the senses of other people, including Nen sensing.
- The Power of Trust: Reveals his powers only to those he trusts, and since his secondary power is a potential Story-Breaker Power, that's not very many.
- Satellite Character: His existence in the story is basically an excuse to not give Knuckle an invisibility power out of nowhere in the final battle. And also foreshadowing for the final power-up of Gon.
- Squishy Wizard: Knows without his Invisibility power, he has no way to defend himself. Good luck finding him though.
- You Killed My Father: Part of his motive for turning against the king was because Peggy, one of the Chimera Ants the king killed shortly after being born was Meleoron's foster father when they were both human.
Colt / Kurt
Voiced by: Hirofumi Nojima (Japanese), Zach Aguilar (English)
A hybrid of unclear animals who was once one of the top commanders of the Queen, serving one rank under the royal guards. He was the first Chimera Ant born from the consumption of human DNA, and as a result the first to possess the ability to speak. Thus, he was the first one the Queen designated as a commander. Colt is one of the commanders who fled the hive in Neo Green Life after the King was born and decided to directly seek help from the extermination squad. He knows a lot of inside information about how the hive works, as well as the Royal Guards and their abilities. He has chosen to stay far away from the battle sites and thus hasn't been seen for some time. His nen ability is unknown.
- Big Brother Instinct: Very much so. It's his identity's bedrock and the key to his human memories.
- Decoy Protagonist: In a sense. Colt starts off as the Chimera Ant that gets the most focus of the arc and was something of a Token Good Teammate to the ants. That left the impression that he would have a more important role in the grand scheme of things, but then he gets pushed to the background After the Ant Queen dies, and Colt defects with her final child.
- Declaration of Protection: Towards the Ant Queen's last baby who turns out to be Kite reborn.
- Defector from Decadence: After witnessing just how little the King values his subject's lives, he leaves the hive to warn the hunters about Meruem's birth.
- Doting Parent: Many, many toys can be seen in Kite's room.
- My Greatest Failure: He blames himself twice for not saving the lifes of his human sister Reina and the Chimera Ant Queen.
- Noble Demon: Originally, but makes a HeelFace Turn after the Queen is killed.
- Promotion to Parent: Takes one peek at the Queen's second, mostly unnoticed, attempt at a royal child... and promotes himself from "Brave Big Bro" to "Doting Daddy" on the spot; no second thoughts, no questions.
- It's very easy to put this simply down to Chimera Ant programming plus whatever bird instincts provided the wings, but... he skips right past "Obsessive Royal Guard" or "feed the chick" and gets right to working on 1) surviving and 2) organizing a legal way to earn money to live alongside Hunters and humans so he can raise a kid (not just "the princess") in a relatively safe and stable environment. This is 100% Kurt/Colt, character growth included.
- Punny Name: His name Colt is a phononym to Kurt.
- The Reliable One: It's easy to forget that this level-headed organizer and practical-minded problem-solver with the air of a stern-but-kind headmaster... isn't even a teen — even when putting both lives together back-to-back.
- Winged Humanoid: He has a pair of white feathered wings.
Voiced by: Issei Futamata (Japanese), Cam Clarke (English)
- Bookworm: Constantly seen with a book at his side. It was apparently a trait he also had when human.
- Cool Old Guy: He is not really old but his appearance invokes this.
- Luke, I Am Your Father: It's revealed that he was Meleoron's foster parent when they were once humans.
- Mauve Shirt: An important character who helps his fellow Ants understand human society, only to be killed in one stroke.
- Off with His Head!: Meruem's second kill.
- The Smart Guy: Of the squad leaders, as he often helps explain human concepts like names to the other ants.
Hagya / Leol
Voiced by: Jiro Saito (Japanese), Jamieson Price (English)
One of the commanders and the direct superior of Hina and Flutter, among others. Part lion, part human, he has remained in service to whoever is the current monarch of the Chimera Ants though always with treacherous intentions. He is somewhat annoyed at his subordinates' ditsiness and wishes they'd think things through.
Leol's nen ability takes the form of an iPod-like device. Leol must perform a good deed for a nen-powered individual and then let that individual know that he or she owes him. For the next 24 hours, Leol can then select that ability for use as if it were a song on the device. Leol steals a water-based ability from one of Morel's men and takes Morel on. Leol meets his end through carbon dioxide poisoning, as Morel used his impressive breath control to displace the oxygen from the enclosed space they fought in.
- Animal Eye Spy: Borrowed Flutter's ability.
- Catchphrase: "I was once the king of the jungle."
- Cool Board: Can use a surf board made of Nen called Inamura as a part of his borrowing ability.
- Conditional Powers: To borrow an ability he must have seen it or know its name. He must also help the designated person and she has to express his gratitude.
- Dark-Skinned Blond: In the 2011 anime.
- Do Not Call Me "Paul": He changes his name to Leol and he doesn't like it when he's called Hagya.
- It becomes a plot point when Ikalgo uses Flutter's corpse and spies in the chimera ant base. Because Ikalgo never knew his new name, Bloster and Welfin notice he is suspicious and later try to assault him.
- Flat-Earth Atheist: Due to being a lion prior his transformation into a Chimera Ant, he has no concept of God.
- Giant Wall of Watery Doom: BIG WALL.
- Good Samaritan: Weaponized.
- Half-Human Hybrid: Lion-man.
- Hoist by His Own Petard: When fighting Morel, Leol uses the ability of a hunter he stole from. This Hunter turns out to be one of Morel's old friends, so Morel is fully aware of the flaws behind the ability and uses it to his advantage.
- Making a Splash: Technically not his power, but it's the only one we ever see used on offense.
- Powers as Programs: Leol can borrow powers from people who owe him a favor.
- Prongs of Poseidon: Can conjure a harpoon when using Inamura.
- The Starscream: Leol is among the most treacherous and power hungry of the Ants and was notable for his bad behavior and lack of loyalty under the Queen. When he went under the employ of the King it was explicitly to overthrow him eventually and take his power for himself.
- Tornado Move: Tornave.
Voiced by: Motoki Takagi (Japanese), Cedric J. Williams (English)
An arrogant chimera ant with a serious attention deficit problem and a massive ego. He's also by far the fastest Ant of them all, able to sprint at incredibly high speeds.
- Archer Archetype: In a desperate attempt to defeat his enemy, he creates a crossbow with claws. His opponent points out how stupid that was, since the bolts from a crossbow move much slower than he does.
- Amazing Technicolor Population: Has yellow skin in the anime.
- Attention Deficit... Ooh, Shiny!: When he finally gets a Nen ability, it requires him to keep his opponent busy for eight hours for it to finally take effect. Except that, as his opponent notes, it's impossible for him to keep focused for that long and he quickly becomes bored and sloppy when said opponent refuses to play along.
- Attention Whore: He likes being the center of attention, which made his first Nen ability, which requires both patience and subtlety in order to not get caught, rather ironic.
- When he gets another ability, he brags about it, but no one cares. He's even killed before showing it.
- Awesome, but Impractical: His first ability traps his victim within a dimensional space, and if they don't catch him within eight hours, something (he never clarifies what) will happen to them. Since there's no Required Secondary Powers that forces the enemy to actually chase him, it's useless. Made even more so when catching him also means he can never use that ability again. And that's not even getting into his Attention Deficit... Ooh, Shiny!
- Crouching Moron, Hidden Badass: He may be an idiot, but he still managed to give Morel and Knuckle trouble in his first fight.
- Dodge the Bullet: When policemen attacked him.
- Dropped a Bridge on Him: Or a "Silva", in this case.
- Evil Red Head: In the 2011 anime.
- Fun Personified: He'd rather play around with his enemies than strategize how to defeat them, which led to his humiliating defeat by Morel.
- Harmless Villain: He poorly uses his Nen abilities and is more interested in running around and showing off rather than being an actual threat.
- Humiliation Conga: Cheetu gets pretty much zero respect. His first Nen ability is casually beaten (including a secondary ability he conjures up at the spur of the moment). Afterwards he's given a different ability that he really wants to talk about to anyone will listen, but nobody cares. He's eventually killed in one hit before we ever see it.
- Irony: His first Nen power, "Tag," traps his opponent in a dimensional space and gives them eight hours to dispel it by touching him. There's nothing saying the opponent has to chase him, however, which turns it into a waiting game requiring immense patience; something cheetahs aren't known for, especially ones with Attention Deficit... Ooh, Shiny!
- It Only Works Once: His "Tag" ability is so powerful because he set the limitation that if he gets caught, he can never use it again. Morel catches him.
- Manchild: Technically an adult, and all he cares about is having fun and running around.
- Motor Mouth: Along with his short attention span, he chatters on endlessly, causing others to find him unbearable.
- Mugging the Monster: Cheetu meets his end after trying to pick a fight with Zeno Zolydck. Ironically, it was actually Silva who kills him completely at random, but Zeno snarks that the result would have been the same even if he dodged Silva's attack.
- Panthera Awesome: He's a cheetah Chimera Ant.
- Rapid-Fire Fisticuffs: Due to his speed, his punches are really fast. Unfortunately, this tactic doesn't work on his far more cunning enemies.
- Shout-Out: His last Nen ability was called Monroe Walk. It's all we ever find out about it.
- Small Name, Big Ego: He brags about being really strong, when in fact, he can't even figure out how to use his own Nen abilities effectively due to his short term attention span.
- Stupid Evil: Morel points out he's Too Dumb to Live to come up with a complex plan.
- Super Speed: He is very fast and likes to remind others of that. It's also a Fatal Flaw as he can't comprehend anything faster than him, even if it's his own abilities.
- Unknown Rival: Played with. Morel acknowledged him but pretended the contrary.
- Unskilled, but Strong: While he is able to learn them with ease, Cheetu never bothers to actually test the limitations of his abilities before trying to use them in combat.
- Who Wears Short Shorts?: Cheetu wears tiny, denim short shorts for some reason.
Welfin / Zaikahal
Voiced by: Daiki Nakamura (Japanese), Xander Mobus (English)
A skeptical and suspicious chimera ant that tries to manipulate the events at the castle in order to give him an edge in life. It's later revealed he's the reincarnation of an NGL Underground member.
- Abusive Parents: After he recovers his human memories, he recalls being strangled by his father and ignored by his mother.
- Awesome, but Impractical: Welfin's ability, Missileman, allows Welfin to coerce its target to follow his orders or answer his questions. However, it requires several handicapping conditions to be used (he must "charge" the missile with a question, make a summation to his target, and the target must refuse to cooperate), it is not guaranteed to hit and, if it hits, does not prevent Welfin's enemy to either counterattack or force him to cancel his Nen.
- Dirty Coward: For all of his violent posturing and threatening disposition, Welfin's ability is made for tracking down targets to force Cold-Blooded Torture and information gathering, not for direct combat. The one time it manages to successfully land on its target is when he catches Ikalgo off-guard in the middle of his Heroic BSoD - and he shoots Welfin anyway as the latter starts screaming in pain and shriveling in fear from Ikalgo being Not Afraid to Die.
- Disease Bleach: The fear of being killed by Meruem, coupled with sensing his immense aura, causes Welfin to shrivel up and lose his hair. The narration notes that in the second after realizing what Meruem was planning on doing to him it appeared as if he had aged one hundred years.
- Half-Human Hybrid: Wolf-man.
- HeelFace Turn: After regaining his human memories and being spared by Ikalgo, he realizes that the chimera ants are humanity's enemy.
- Homing Projectile: his Nen allows him to fire Nen-tracking missiles, albeit the missile is not harmful in itself. The brain-eating caterpillars inside the missile are what makes it dangerous.
- Only Friend: To Gyro, in their human life.
- Properly Paranoid: His obscene amounts of paranoia and being on edge around even his own comrades turns out to be the correct guess after Ikalgo's infiltration.
- Smug Snake: He makes some noise about wanting to be the King behind the King and after Youpi dies in front of him he actually thinks he can take on Meruem. Both times his ambition gets shot down and he almost ends up killed.
- Spanner in the Works: He saves the day (and humanity) with a single word.
- Super-Persistent Missile: Missileman homes in on the target and is allegedly undodgeable, as he puts it; their persistence even lasts after they explode, embedding black centipedes of nen within the target to torture them so he can interrogate on his own terms. But given the Awesome, but Impractical conditions above, and the fact that one of his targets can go invisible and completely fool the attack, he only manages to hit one person with them. And they're willing to pull a Taking You with Me, rendering the persistence of the attack completely pointless.
- Thong of Shielding: Codpiece thong. For double protection?
- Undying Loyalty: To Gyro.
Bloster / Brovada

- Gentle Giant: He promises Shidore/Layna to stay with her and he helps her to reunite her with her human mother.
- Giant Enemy Crab: Well, he's more like a crawfish...
- HeelFace Turn: After being spared by Ikalgo and regaining some of his human memories, he stays together with Shidore/Layna and becomes a member of her village.
- More Dakka: From his claws.
- Tears of Joy: After he reunites Layna and her mother, he first refuses to eat with the villagers, but when Layna begs him to join, he shed tears because of the warmth of the village.

A selfish and conceited Chimera ant that attempts to form her own kingdom after the NGL base is destroyed, setting up shop in Meteor City, the home of the Phantom Troupe.
- Amazing Technicolor Population: Has pink skin in the anime.
- Bare Your Midriff: Wore a tube top before the King was born, and then changed to a bra and a corset that still exposes her stomach.
- Berserk Button: Don't hurt her face.
- Blood Knight: Happily joins in on fights even after declaring herself queen.
- Catchphrase: "Mother's greatest failure was XXX"
- Expy: Of Zarbon. They share an obsession with outward appearances, preferring a beautiful appearance over a stronger form. After shedding their respective shells, they both become significantly more muscular, but also more hideous, with reptile-like qualities. In exchange, their power increases drastically.
- Faux Affably Evil: Once she matures, she goes from crude to very elegant in speech, even though she's still a control freak.
- The Fighting Narcissist: Considering she is an expy of Zarbon it's not really surprising.
- Half-Human Hybrid: Scorpion-woman, also some alligator as well.
- Kicking Ass in All Her Finery: Subverted. Feitan destroyed her channel skirt.
- Royals Who Actually Do Something: She is a self-proclaimed queen though.
- She Is All Grown Up: She managed to mature into a more adult form once she became a queen. It's quite beautiful.
- The Smurfette Principle: The only female Squadron Leader, though she's still very dangerous.
- Stripperiffic: She wore nothing but a tube top and underwear at first, and she got even skimpier as a self-proclaimed queen.
- Super Mode: When she removes her stinger, she turns into a giant, grotesque alligator like behemoth.
- Super Toughness: Even a Ko attack wasn't enough to hurt her.

An octopus and a former commander of the Chimera Ants, though he served under the King and prefers to call himself a squid. In charge of an underwater unit, he took on Killua using a set of nen abilities: He can see his immediate surroundings as a set of coordinates to snipe with, and he shoots fleas that drain the subject of their nen. If enough nen gets drained, the subject is depowered momentarily. Ikalgo is also able to climb into the body of a dead person and move them around as if he were that person, though his rifle will appear as a sniper-shaped growth. Inspired by Killua's bravery, he decides to join up with Gon and the others. He makes his way to the East Gorteau palace and sneaks into a basement area to try to rescue Palm. Unfortunately, he finds out Bloster, another commander, is in the basement with him and plays a game of cat and mouse with Bloster to dispose of him.
- Abnormal Ammo: Fires flea-bullets in his first appearance.
- Bad Powers, Good People: Ikalgo can use dead bodies as disguises and infect enemies with flea-bullets, but he's extremely loyal to those who gain his respect and can't even bring himself to kill his fellow Ants.
- Because You Were Nice to Me: He joined the Invasion Squad because Killua spared his life.
- Body Snatcher: Only if it's a dead body.
- Cold Sniper: Subverted. He may be a sniper, but he has strong moral fiber.
- Combat Tentacles: Well, he is an octopus.
- Dead Person Impersonation: How he uses ability during the palace invasion.
- Defeat Equals Friendship: On both the giving and receiving end of this trope. After being defeated and spared by Killua Ikalgo becomes so moved by him that he decided to help him take down the King. Afterwards his sparing Bloster and Welfin's life's leads the two of them to HeelFace Turn themselves.
- Defector from Decadence: After Killua tells him that he considers the two of them to be friends he defects from the ants and helps the Invasion Squad take on the King and his Royal Guards.
- Funny Animal: An Octopus. Not that he likes being called one...
- HeelFace Turn: Goes from fighting the Invasion Squad to joining them.
- I Just Want to Be Badass: And to be a badass you must be a squid.
- Insistent Terminology: Insists on being called a squid, though he's obviously an octopus.
- Nonstandard Character Design: He more closely resembles something out of a Butch Hartman cartoon.
- People Puppets: He can get inside of corpses and use the body as if it were his own, including any Nen abilities that his host had in life. It crosses into Squick territory when he uses Flutter's body, which is already decomposing and stinks horribly.
- Smug Snake: At least prior his HeelFace Turn.
- Thou Shall Not Kill: Despite having both Welfin and Bloster dead to rights Ikalgo ultimately can't go through with killing them. In the long haul this ultimately turned out to be the right decision.
- Undying Loyalty: Double subverted. He was ready to die for his superiors but became a traitor to help the Invasion Squad...risking his life on several occasions while doing so.
- You Are What You Hate: Literally. He is an octopus.

A huge Jerkass Chimera ant with a bone to pick with everyone around him. Surprisingly, he's the first to learn Nen after Gon and Killua knock him silly.
- Always a Bigger Fish: He developed a desire for becoming the king himself while on a power high. He subsequently lost it after sensing Pitou.
- Break the Haughty: Pitou instantly broke his spirit after he awakened his Nen abilities and experienced a Power High.

The previous ruler of NGL behind the scenes. Gyro lives to cause misery and death, spawned from his absolutely atrocious upbringing and the mistreatment from his father. After being eaten, it's revealed he's somehow reincarnated into an Ant with all of his memories intact, and is now roaming the land, looking to rebuild his kingdom.
- Abusive Parents: Up to Eleven.
- Break the Cutie: He believed his father only wanted to keep him out of trouble to protect him, and it turns out he only didn't want to have to bother taking care of him.
- Catchphrase: Don't die until you die.
- Chekhov's Gunman: Most likely set up to be this; the manga outright says that Gon and Gyro haven't met each other, but they will eventually.
- Determinator: The reason why he didn't become a soldier ant, a loyal one anyway.
- Diabolical Mastermind: Managed to create a drug empire disguised as a luddite society.
- Evil Counterpart: Based on his backstory, he's being set up as this for Gon. Gon had an absent father who left Gon in someone's care (who made a much better parent) and who Gon had to go through extreme lengths to meet, but who nonetheless does care about Gon. Gyro, on the other hand, had a father who was always around, but who was extremely abusive and didn't care about Gyro at all. And while Gon searched for (and eventually met) his dad, Gyro made sure his dad wouldn't be around...
- Freudian Excuse: He became how he is because of his father.
- From Nobody to Nightmare: Especially noteworthy since this happened before he became a Chimera Ant.
- Minor Major Character: The way his backstory is told, you'd think he'd be a Big Bad, but so far he's only been referenced twice in the series thus far.
- Only Friend: As humans, Welfin and Gyro were such direct comrades since childhood that Welfin served as his personal bodyguard at the NGL. Welfin even refers to him as a brother unrelated by blood.
- Pet the Dog: Welfin and Gyro were close friends in their former life to the point that Gyro saved Welfin when they were kids - likely because Welfin's abusive father trying to murder him reminded Gyro of his very own problems. Whether there was an ulterior motive is unknown so far as we only know this from Welfin's perspective.
- Reincarnation: And unlike the others, he immediately left the colony to reestablish his empire.
- Self-Made Orphan: Not that the father didn't deserve it, being a complete and utter Hate Sink.
- Street Urchin: After killing his father.
- Tragic Villain: He grew up thinking he was only being rejected by his father in order to build humility towards others, but it later turns out he only said that in order to not have to be bothered by his existence. This event broke the poor boy's heart, driving him to want to create despair in everyone.
- Used to Be a Sweet Child: Till daddy was revealed to never have given a care about him
- Woobie, Destroyer of Worlds: His father abused his childhood and didn't love him in the slightest. Now he wants to spread evil thorough the world.
