- Darker and Edgier: The darkest arc in the series to date, and arguably darker than most shonen stories in general.
- Ensemble Cast: The arc doesn't seem to have a focus on any singular protagonist. The story shifts between multiple characters at a time, including Gon, Killua, multiple members of the Hunter Organization, and even the Ants themselves.
- Sorting Algorithm of Evil: While HXH has largely averted this use of the trope (see its entry on the page for more details), this arc is closest the series has gotten to utilizing this trope in a more straightforward manner. The arc begins with low-level grunt soldiers who are easily dispatched. Then they learn about and develop their own nen, and while Gon, Killua, and Kite have little trouble with them, they begin posing more of a threat to the NGL as they feed more citizens to the Queen. The heroes start really having trouble when the Royal Guards are born, as they quickly overpower Kite and force Gon and Killua to retreat and getting the higher ranks of the Hunter Organization involved. Finally, the King is born, who winds up becoming the most powerful character in the series and poses a threat to the world at large.
