Dennis the Menace is the main character in the Beano comic and the fifth student of the seven pupils in Bash Street School's Class IA. He owns an Abyssinian Wire-Haired Tripe Hound named Gnasher and lives in Beanotown. His most famous features are his spiky black hair, his red and black striped jersey and his grey boots. Another comic, also named Dennis the Menace, exists in the USA.
Dennis, as his name suggests, is a menace who likes to cause trouble wherever he goes. His main arch-enemy is Walter the Softy, who is the complete opposite of him. Whatever he loves, Dennis hates.
If he is defeated in the end it is quite often a result of his parents, or other Beanotown residents, such as Softies, ruining his fun by laying traps for him, using softy stuff such as soap or perfume on him, or forcing him to go to one of Walter's tea parties. On one too many occasions has Dad spanked him.
He first appeared in the Beano in 1951, but Gnasher didn't make his first appearance in 1968.
