Artemis, a Mythos cyborg engineered by Dr. Gaia—a defector from the Black Ghost organization—is conditioned to embody the Greek goddess of the hunt, complete with a bow launching explosive energy arrows. Her human past erased, she adopts the fabricated role of Apollo’s elder sister, bound by artificial kinship. Her striking appearance features dark teal hair swept into a ponytail, a gold-studded headband, and attire blending ancient Greek tunics with gladiator sandals, her obscured eye amplifying an aura of mystery.

Programmed to aid the Mythos’ crusade against humanity, she defies her peers through covert empathy, resisting needless bloodshed. During the 00 Cyborgs’ initial clash, she shields them from Apollo’s wrath, insisting excessive violence undermines their “divine” mandate. This nurturing instinct extends to Pan and Atlas, whose rivalry for her favor positions her as both mediator and emotional anchor within the group.

Encounters with Cyborg 009 ignite doubt in her divine identity, his claims of their artificial origins clashing with her memory gaps. Though outwardly loyal to Apollo, she covertly mends 009’s wounds and urges his escape from Magma Island. Her fragile faith shatters when Dr. Gaia betrays her, a gunshot wound exposing their existence as manipulated weapons. In her final act, she intercepts Apollo’s lethal strike against 009, confessing Gaia’s lies and begging for humanity’s mercy as she perishes.

Pan and Atlas’ grief over her death mirrors the Mythos collective’s ideological collapse. Her arc—a struggle between indoctrinated dogma and innate compassion—frames her as a catalyst for redemption, her rediscovered humanity defying systemic control.

Exclusive to the 2001 anime, this iteration supplants the manga’s Helena, integrating unused 1979 concepts by Shotaro Ishinomori. Spin-offs later reconcile her as a fusion with Helena, balancing mythological aesthetics with a narrative centered on identity crises and the tension between programmed purpose and latent empathy.
