Art3mis is a famous gunter. She is first mentioned in Chapter 0002. She is the writer of "Arty's Missives," a blog dedicated to her search of Halliday's egg. Wade/Parzival describing her blog entries as endearing, intelligent, and self-deprecating, he admits to having a crush on her. This crush is frequently addressed throughout the book and proves to complicate their competition.
She is named after Artemis, the Greek goddess of the hunt.
Art3mis is intelligent, independent, funny, and bold. She is extremely knowledgable of "gunter" culture. Art3mis is fiercely protective of her freedom and doesn't like to rely on anyone else — especially when it comes to gunting. Furthermore, Art3mis doesn't wear her heart on her sleeve; while Wade confesses his undying love for her, she remains hesitant and cautious, believing online romance to be impossible. Her refusal to return that four-letter word to Wade implies that she's motivated by her goals as a gunter as opposed to those as a love-hungry teenager.
She may succumb to her feelings after the final battle, but it's important to note that she refused to meet with Wade beforehand. This decision indicates her values, as if to say, "let's get the job done first."
Wade describes Art3mis' avatar as raven-haired. She has a pretty face: hazel eyes, a pointy chin, rounded cheekbones, and a perpetual smirk. He also adds that her features look realistic, in comparison to the other avatars, as if her actual face had been scanned into OASIS as a skin.
He has referred to her avatar's body as "unusual." While a majority of female avatars assume one of two shapes, either thin like a supermodel or top-heavy like a porn star, Art3mis' frame was short and curvy — Rubenesque.
After finding her file in the IOI (Innovative Online Industries) database, Wade discovers that Art3mis looks identical to her OASIS avatar with the exception of a birthmark. The birthmark, a port-wine stain, is on the left side of her face.
The file also mentions that she is 5'7" and 168 lbs.
