Neferpitou, nicknamed Pitou, is a cat-humanoid Chimera Ant and the firstborn of the Chimera Ant King's three Royal Guards.
Neferpitou is very loyal to the King, just like the rest of the Royal Guards that would sacrifice themselves for him. Neferpitou gets distracted easily, loves to play a lot and that makes them the most curious of the three Royal Guards. Hence their cat-like appearance, Pitou is a cat Chimera Ant who loves to play with their opponents like a cat would with their prey. Despite their cheerful and playful manner, Pitou has a sadistic and terrifying personality as well.
Unlike Menthuthuyoupi and Shaiapouf, Neferpitou does not seem to mind much in regards to Meruem's later newfound interests with Komugi. Thus, among the three Royal Guards, Neferpitou is the only one that greatly prioritizes Komugi's safety as opposed to how Menthuthuyoupi and Shaiapouf hate Komugi, which causes tension among the guards.
When the day of the selection finally occurs, the Extermination Team attacks the palace and causes massive damage. The King's consort, Komugi, is mortally wounded and under the King's orders, Neferpitou heals her; Neferpitou noticeably begins to sheds tears, understanding the King's sorrow and the importance of the order.
Though a promise was made to go with Gon to Peijin to restore Kite, once they've reached the area, Neferpitou affirms that it is impossible and subsequently prepares to kill Gon. Gon then forcibly ages his body by sacrificing nearly all of his aura and kills Neferpitou in battle.
