Artemis Fowl II is the titular main protagonist of the novel and its movie Artemis Fowl. He is a child prodigy who is originally an adversary but eventually become an ally of the fairy civilization. He is Irish, black hair, blue eyes, very pale skin, a nearly dysfunctional family with an elaborate history of crime, a loyal manservant and bodyguard called Butler, millions of euros at his disposal, and the highest intelligence of his generation. He is also a criminally good genius who once used his intelligence to steal money to rescue his father, but has since then used his abilities to help the world and the fairy civilization.
Artemis was very intelligent at a young age. He grew very close to his bodyguard, Butler, who he viewed as a father figure, albeit one who obeyed orders. He had a lot of respect for his father, Artemis Fowl I, who taught him the family creed: "Aurum est Potestas", or "Gold is Power".
After his father went missing when the boat ""Fowl Star" went down in Russia, Artemis did everything to find him. He needed large amounts of money to search for him. When his mother, who was having an emotional an psychological breakdown, spent the family's remaining money to save the last silky sifaka lemur, Artemis stole the lemur and sold him to a group called the exinctionists to acquire a large amount of money.
Artemis began searching the internet an discovered that faries were real. (This is later revealed to be the result of his future self going back in time to the lemur incident).
