Argus Filch is a character from the Harry Potter series, created by author J.K. Rowling. He serves as the caretaker of Hogwarts School of Witchcraft and Wizardry, responsible for maintaining the school's cleanliness and order. Filch is known for his strict demeanor and dislike of students, often patrolling the halls to catch those breaking school rules. Filch is a squib, meaning he was born into a wizarding family but lacks magical abilities. This often makes him feel resentful towards the students, as he cannot use magic to enforce discipline. He is frequently accompanied by his cat, Mrs. Norris, who helps him monitor the students.
