Antagonist
Character Role Analysis
Boov and Gorg
Even though the Boov turn out to be not as bad as the Gorg, they're still antagonists because they're fighting against our main girl, Gratuity. Throughout the book, we see these two races of aliens fight with the humans, force them to live in cramped and unfair conditions, and even plan to kill them off. Yep, these folks are definitely the antagonists. There's no clear reason for the Boov and Gorg to hate the humans and want to destroy them, yet they actively work against them, and they're behind pretty much every problem Tip encounters.
