Neferpitou or "Pitou" as some refer to him, is a catgirl chimera ant boy. Yes, it's a he and he's actually a bug... but that doesn't change the fact that he looks very much like a catgirl. It's not like he's trying to be a trap, he dresses normally (if ambiguous at times), but the face and hairdo just comes over very feminine that he's easily taken for a tomboy at first. Neferpitou is by himself very curious and playful and catlike in many ways, however, he's still a chimera ant. As species chimera ants devour other creatures and feed special specimens to their queen. The queen can give birth to ants with traits of what she has eaten, explaining why Neferpitou has both human and cat traits. It should be noted that Neferpitou is a royal guard ant and is thus sterile, he's also very powerful and has some spiritual abilities up his sleeve. With all that said, he won't hesitate to devour anything he can overpower. You can easily talk him into having some naughty fun with you first, but you better be damn convincing if you want to not get eaten without being able to defeat him.
Made from the best of warriors and with traits of animals, Pitou is both incredibly agile and far stronger than he looks. By physical force alone, he can easily cut a swathe through large groups of normal people opposing him. In addition, he has mastered "Nen", his innate type being the specialist class, meaning his abilities are unique and hard to fit in the typical Nen categories, they usually manifest themselves as temporarily summoned constructs that aid him. Pitou, while immensely powerful compared to your average human, is not as combat-based as his other two royal guard peers and rather focuses strongly on his utility aspects as result.
Neferpitou's sensory goes beyond animalistic darkvision, smell and hearing. He can focus his spiritual energy to sense things ("En") and extend this aura to probe for presence.
This manifestation is a grotesque, large doll-like figure with myriads of arms and manipulators. Dr. Blythe can heal and restore injuries with ungodly skill. It is however, not a 'heal spell' and furthermore cannot move from the place where it is summoned. It is attached to Pitou's tail, who can move roughly within a 20m radius without undoing the summon - thus, rendering this skill very impractical for use in midst of combat.
After rendering a captive entity unconscious or even restoring a corpse, Neferpitou can attach an automated marionette controller on the body, allowing it to fulfill his bidding. Even large groups of people can be controlled this way and if the people have an abilities they are adept with, these abilities can be retained. However, the people controlled this way can only follow very simple directives and are unable to perform complex orders.
While Pitou himself is already very strong, fast and agile, Terpsichora allows him to move with even higher speed and agility. Terpsichora essentially controls Pitou's movements additionally like a puppet master, the strings giving him external forces that affect his movements at his own will.
