Hornet is the fearless and nimble princess-protector of Hallownest. With a lethal needle and iron will, she watches over the kingdom, and protects it from further destruction. Hardened by the harsh world, she has a stoic and somewhat inhospitable disposition, though she isn't a bad person by any means.

While Hornet's voice is soft, she speaks in an uninviting and determined manner. She's the type of person who you know means business just by their tone. Her disdain and bravery is certainly audible in her voice. Makoto Koji's performance as Hornet in the original game is a great reference to base your interpretation off of.
