Samantha Evelyn Cook aka Art3mis
Art3mis is the quintessential girl geek. She is tough, courageous, diligent, and adventurous. Naturally competitive, she is not afraid to take on the most difficult challenges in the egg quest. She is the second person to find the Copper Key (after Wade). A member of the High Five, she is prepared to make sacrifices to defeat IOI's plans for the OASIS.
Despite her prowess as a gunter, however, Art3mis is haunted by self-doubts. Throughout the story, it is suggested that she struggles with body image issues: her port-wine stain birthmark is the bane of her existence, and her preoccupation with it arrests her developing intimacy with Wade. Art3mis makes the decision to leave Wade partly because she believes that he would be repulsed by her real-life appearance. Like Wade, Art3mis has to come to terms with her self-doubts before she can confront the enemy who threatens their freedoms. In the final battle at Anorak's Castle, she unequivocally supports Wade and plays an instrumental role in helping him overcome his Third Gate challenges.
