Jimmy Hopkins (Bully) Is a principal character.

Jimmy is a 15-year-old boy, of stocky build and very short compared to the other students, even shorter than the girls he can kiss; you can notice how he stands on his toes to kiss girls. He has red hair, brown eyes, and freckles on his cheeks. He also has a reddish nose and a gold earring in his left ear.

When he arrives at the academy, Jimmy can be seen with very short, but not completely shaved, hair. He wears a brown jacket over a white T-shirt, blue jeans, and white sneakers. His school uniform consists of a blue Bullworth vest over a white shirt, khaki pants, and the same sneakers he wears upon arrival.

Jimmy isn't a particularly muscular student, but he's not a weakling either. Despite his lack of muscle, he makes up for it with his inexhaustible energy, which allows him to sprint without tiring, have the agility to climb walls, and even fight. Jimmy is a very troublemaker; he was expelled from seven schools. He worries a lot about his mother, who continually married other men.

Jimmy has the typical personality of a daring schoolboy, who doesn't care about anything or anyone except himself. He isn't usually that violent; in fact, he only resorts to violence when challenged to a fight. He usually has a good side, helping those in need, although he usually demands something in return (money or objects).
