Kimera, an androgynous humanoid alien bearing vampiric traits, has striking heterochromia and vivid green hair. Their hermaphroditic biology designates them as the last viable Mother tasked with perpetuating a near-extinct extraterrestrial vampire species. Hailing from a dying planet plagued by reproductive collapse, Kimera once rejected blood consumption and embraced pacifism, haunted by memories of previous Mothers exploited to death for reproduction.

After crash-landing on Earth, humans imprison Kimera in cryogenic stasis. Upon awakening, they bond with Osamu, a human salesman, conflating him with Kianu—a past lover from their homeworld. This bond resurfaces fragmented memories: a romantic entanglement with Kianu and Kimera’s defiant refusal to comply with their species’ reproductive mandate. Their biology ignites conflict as Ginzu, a disfigured vampire, pursues forced breeding, while Kianu plots euthanasia to avert planetary catastrophe.

Kimera’s behavior shifts unpredictably. Initially passive and silent, they unleash violent retribution when threatened—draining assailants of fluids after enduring sexual assault. This brutality contrasts starkly with prior pacifism, hinting at trauma or primal biological drives overriding ethics. Flashbacks reveal a once-expressive, emotive being, now replaced by emotional detachment post-awakening, save for fleeting tenderness toward Osamu.

In their ambiguous conclusion, Kimera escapes captivity, confronts Ginzu and Kianu, then flees Earth with Osamu. Aware their offspring could threaten humanity, they nonetheless choose solidarity, embodying precarious hope for coexistence. Their fate remains unresolved, unchronicled in later records.

Physically, Kimera regenerates injuries, drains life via fangs or retractable tentacles, and emits luminescent skin flares during emotional peaks or transformations. Their androgyny and dual physiology perplex humans, compounded by translation errors in localized records obscuring their true nature.
