Tersilla

"You may have won this time, Stilton, but you'll see us again soon!"

Tersilla is a leading antagonist from the Geronimo Stilton comic book series. She is the daughter of Catardone III, leader of the Pirate Cats, and is aided by their henchman, Bonzo. Although Catardone leads the gang, Tersilla is the real brains behind the operation. Spoiled, selfish, conniving, sly, and sadistic, Tersilla plots with her father and sidekick to change the course of time in history to get rich. Her schemes involve kidnapping important figures, stealing treasure, and especially, taking out Geronimo Stilton. But at the end of every book, she is outwitted and vows to Geronimo that they will meet again. Tersilla makes an appearance in Geronimo Stilton: The Golden Statue Plot.
