Artemis Fowl is a genius, plain and simple. He has translated the fairy Book, kidnapped a fairy, separated the fairy People from some of their gold, and escaped a time-stop. All at the age of twelve years old!

Artemis Fowl has pale skin and what used to be deep-blue eyes, but one of those eyes was swapped for a hazel with Holly Short, during the transfer of Hybras from Limbo. He also has raven black hair. He often treats people to a vampire grin, sending shivers down their spine. He is from an Irish family, and lives near Dublin, in Fowl Manor.

He has by his side the giant Eurasian manservant Butler. His mother's pet name for him is Arty, and, strangely, he does not mind when Juliet Butler calls him this. Artemis attends school at St. Bartleby's School for Young Gentlemen, when he attends school at all, and is not on an adventure with the Fairy People.
