Some cartoons don’t try to make the main character perfect—and that’s exactly why they work. Horrid Henry builds its world around a boy who breaks rules, argues back, and somehow still feels real.
Set in a typical neighborhood with school, family, and everyday problems, the show gets its humor from how different each character is. Some are strict, some are annoying, and some are just trying to survive Henry’s chaos. Here’s list of the main characters.

Henry
Henry is loud, rebellious, and always looking for shortcuts. He doesn’t like rules, homework, or being told what to do. Most of his plans are about avoiding responsibility or getting what he wants quickly.
Funniest quirk: Creating clever but messy schemes that usually backfire at the worst moment.
Peter
Peter is Henry’s younger brother and the complete opposite of him. He follows rules, behaves politely, and often becomes the “favorite child” in the family.
Funniest quirk: Always doing the right thing, which makes Henry even more frustrated.
Mum
Henry’s mother tries to maintain order at home. She deals with daily arguments, complaints, and Henry’s constant trouble.
Funniest quirk: Switching quickly from calm to strict when Henry crosses the line.
Dad
Henry’s father is more relaxed but still gets caught up in the chaos. He often tries to handle situations calmly, though that doesn’t always work.
Funniest quirk: Getting overwhelmed when both kids create problems at the same time.
Miss Battle-Axe
Miss Battle-Axe is Henry’s strict school teacher. She expects discipline and has very little patience for misbehavior.
Funniest quirk: Catching Henry almost every time he tries to break rules.
Moody Margaret
Margaret is confident, bossy, and likes to be in control. She often clashes with Henry because both want things their own way.
Funniest quirk: Acting like a leader and expecting everyone to follow her rules.
Rude Ralph
Ralph is one of Henry’s close friends. He enjoys mischief just as much and often joins Henry in his plans.
Funniest quirk: Supporting Henry’s ideas without thinking about the consequences.
Sour Susan
Susan prefers rules, order, and doing things properly. She often gets annoyed by Henry and his friends.
Funniest quirk: Complaining about everything that doesn’t follow the rules.
Beefy Bert
Bert is friendly and always hungry. He enjoys being part of the group but focuses a lot on food.
Funniest quirk: Thinking about food in almost every situation.
Bossy Bill
Bill likes to take charge and tell others what to do. He often acts as if he’s the leader.
Funniest quirk: Giving orders even when no one asked him to.
Conclusion
The strength of Horrid Henry comes from its characters. Each one represents a different type of personality you see in real life—rebellious, disciplined, bossy, or easygoing.
Together, they turn simple daily situations into funny and relatable stories. That mix of chaos and familiarity is what keeps the show enjoyable even after many episodes.
