Artemis Fowl II is the main protagonist of the novel and it's movie Artemis Fowl. He is a child prodigy who is originally an adversary but eventually become an ally of the fairy civilization. He is Iish, 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 abilites 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).
Artemis and Butler blackmail a fairy in Ho Chi Minh City to get a copy of The Book, which is a fairy bible containing all of their secrets. Using this information, Artemis, along with Butler and Juliet Butler, manage to kidnap Captain Holly Short of the Recon division of the Lower Elements Police. The LEP, who led by Commander Julius Root, lay siege to Fowl Manor, and surround it with an inescapable time field. Artemis negotiates to get gold from the fairies, but "accidentally" lets slip that the faries can't enter while he is alive. The fairies interpret this to mean that they can go in once he is dead. Briar Cugeon of the LEP wanted to send in a bio bomb to kill everyone, including Holly, but Root forbade it. Instead, he sent in a criminal dwarf named Mulch Diggums to infiltrate Fowl Manor. Around this time, Holly excaped, mesmerized Juliet, and recovered some equipment that Butler stole. After Mulch Diggums escaped from Butler and faked his own death, Briar Cudgeon sent in a Troll. Butler was initially defeated by the troll, but Holly healed him, allowing Butler to defeat it. After this, the faires send Artemis the gold. Artemis paid Holly half the gold to heal his mother, and then releases her. Following this, the fairies sent in the bio bomb. Artemis drugs Butler, Juliet, and himself, causing all of them to fall asleep and escape the time field, preventing the fairies from killing him or taking the gold.
