The Villains are the Antagonists from the Geronimo Stilton books and animated series. This can range from annoyances like Sally Rasmausssen and Veronica Stiffwhiskers to actually serious threats like the Pirate Cats, the Mafia and other ruthless criminals who tried to commit crimes but are always foiled by the main protagonist Geronimo Stilton. Despite the main villains are very dangerous, they aren't so very lucky in the end.
Fact: Geronimo, by his philosophic description is pretty much a skinny weakling without muscular development. he is very weak, he's not physically fast, horrible durability and stamina, very low pain tolerance. but makes up for very excellent in academics, and has insane luck when it comes to danger.
