Introducing humans to the Chimera Ant food chain allowed impossible things to happen. It made them bigger, stronger, faster, smarter, and more independent. Aside from the King himself, Neferpitou is the finest specimen of Chimera Ant evolution there is. At a glance, Neferpitou is a monster. The Royal Guards and their King have the ability to utterly wipe out entire country's worth of humans: choosing to eat some, converting others into soldiers, and callously killing the rest. Pitou is capable of utter cruelty, not just at the order of its King (which Pitou follows to the letter) but also in its own time.

Pitou's cruelty, however, is a cat's playful cruelty. It is in its nature to be a hunter, to toy with its prey. This concept of the ant's 'nature' is a moral dilemma that is reflected on several times within the arc, with several characters questioning if it is right to eradicate a species for their nature alone. Also if it is right to kill them when they exhibit human intelligence and at times human emotion. In fact, nearly all of the ants, with the exception of Shaiapouf (butterfly satan), learn to respect, befriend, or care for humans in some way, which gives several of the heroes sent to stop them pause. Who becomes the monster in that situation? This is a question you are meant to ask during the arc.

For Pitou's personality, this question informs that they are both dangerous, as well as innocent. They have an animal's lack of real malice or intent for evil. They have done things the humans see as evil, but it was done due to biological imperatives of survival, expansion, obedience. However, several times within the arc, Pitou's aura is described as being very malicious but, each time this description was made, Pitou was protecting either the pregnant Queen or the beloved King. Why wouldn't Pitou have malice against anyone trying to enter the ant's domain and possibly injure the monarchs? Its immense nen just allows it to project and amplify its protectiveness. Killua notices this trait when Pitou is desperately trying to protect Komugi from Gon, comparing Neferpitou to a mother cat. A cat's instinct to protect its young is instinctive and less emotionally complex than a human's: but is that less worthy? Despite the fact that Pitou has used its powers in unfortunate ways, it is still a guardian and a healer.

Pitou is loyal to its core, it was born with the imperative to protect the King and this mission is what it lives for. The strength of this genetic wiring can be seen late in the arc when Meruem attempts to bow before a converted Palm. Although formerly human and against the ants, Palm begins to cry and screams that he can't bow before her because he is her King. Palm is only a soldier ant, for a member of the Royal Guard this devotion and adoration is much greater.

As Meruem learns to care for and respect humans through his interactions with Komugi, the same seeds begin to take root in two of his Guards. He asks Neferpitou to look out for the human girl, and then when the palace is attacked, to save her life. Neferpitou is forced to articulate this to Gon, saying that it cares for the girl because its King cares for her. Unlike Pouf, Neferpitou can understand the King's relationship to the girl, in its own way, because it also had affection and admiration for Kite. Although it showed that in a gruesome way. Considering Meruem ripped his own arm off for Komugi, he also showed his affection morbidly, this is because the ants just don't really understand human affection. Their interactions are built on hierarchy, where behavior is strictly enforced and expected and has none of the flow and optional friendships of mankind. They take their bonds very seriously, especially in the royal court.

Still, as examples of human friendship and spirit are provided, the ants learn. When Neferpitou is taken to Kite's puppet by Gon, it apologetically tells the boy that the body has no soul and cannot be healed. It observes Gon's sadness and anger, and apologizes again in explaining that it must kill him, in order to protect the king. This one-sided conversation shows that Pitou is capable of coming around to certain aspects of human nature, but is ultimately still bound by the ant paradigm.

I’m sorry to say this, but, I must kill you. For the king.

This dissonance is observed by Chairman Netero when he fights Meruem, he recognizes that both human and ant are present, and that some human kindness is sprouting, but expresses his doubts that the creatures can ever fully overcome their biological wiring and live peacefully with mankind. Certainly not while their wildly powerful King and Royal Guards live to embolden the race and bolster its numbers.

What I would like to summarize about this based on these various anecdotes is that Neferpitou has conflicting sides to itself. It has the intelligence and individuality of a human, the playfulness and curiosity of a cat, the obedience and loyalty of an ant. It is not entirely human, and to expect it to behave as such is not really respecting its nature. But its immense power and lack of clear morality make it incredibly dangerous and worthy of fear. With its particular set of powers and roles, it is as capable of devotion and caring as it is for thoughtless sadism. It doesn't really have any reason to question what it does, it hasn't learned enough about people to know what hurts them or they deem wrong. They have different rules than ants, and those rules cannot truly be learned without first-hand experience and guidance.

At surface level, Pitou's most obvious traits are likely the cat ones. It appears inquisitive and eager, except when it's being fickle and standoffish. Separating Pitou from the King and that duty will allow me to lower its violence level, since it will not be on guard for such dangers towards its beloved King.

Possesses three nen abilities:

ː Puppeteers - Nen dolls which attach strings to victims, able to control them with simple commands from Neferpitou. It can maintain a number of these puppeteers simultaneously.

ː Terpischora - A specific puppeteer Pitou summons to control its own body. Terpischora can use Pitou's body above and beyond its already immense capabilities. Remains in effect until the nen dissipates or the body is well and truly destroyed. Even after Gon took off Pitou's head, the body continued to attack.

ː Dr. Blythe - Blythe is a doll which grows from Pitou's tail. When summoned, Blythe takes all of Pitou's concentration and all puppets and increased awareness (called en) is dropped. Blythe can surgically treat any wounds, although cannot revive the dead. Blythe cannot move from where it was summoned, and Pitou's tail will only stretch up to 20 meters away from it.

Other Skills:
+ Speed - Can move faster than the eye, can propel self long long long distances in seconds, despite lack of wings.
+ Strength - Can carve off limbs. Can withstand large amounts of damage, has a carapace.
+ Presence - Enhanced senses, both the usual five senses as well as its nen power. Can extend its nen out in a cloud which allows it to be aware of things outside of its sight, and is also so terrifying that intruders have a hard time proceeding into the nen once they reach it. Specifically, other nen users can feel how strong they are.
+ Intelligence - Neferpitou is terrifyingly intelligent. I think the most apt example of this is that it read a couple of books about how the human brain works, went 'I get it now' and was immediately able to cut open a hunter's head and begin torturously manipulating the subject's brain to force the truth about nen abilities out of him. Similarly, from that explanation, Pitou was immediately able to grasp how nen worked and master the abilities of its choosing.
+ Instincts & Reflexes - Catlike, Pitou always lands on its feet.
