E-001, AKA Eveline, was created by a crime syndicate involved in Bio-Chemical research, murder, money laundering, weapons & drug trafficking. She was cloned from a long-dead girl & spliced with a sample of a substance called "mold" to grant her powers of regeneration, mind control, hallucinations, shapeshifting & infecting people with the mold to and mutate them. Eveline was artificially aged to appear as a 10-year-old girl to suit her purpose for infiltration.

Eveline is 5'1, 99lb, & has pale-white skin, long greasy black hair & grey eyes. She wears a dark-grey knee-length dress with black long-sleeves, rolled-up to her elbows. The dresses crew-shaped neckline is black, the dress also has a waist-strap & she wears a pair of black 9-hole combat boots.

Eveline is bloodthirsty & homicidal but is not aware of the evil she commits. She is a severely disturbed & traumatized young girl who abused her powers to infect others, making them into her vicious servants. Despite Eveline's actions & playfully sadistic attitude, her obsession with family seem to have been brought on by her orphaned upbringing as a bioweapon. She acts like a bratty & entitled girl who wants to know what being loved by a family feels like & does not necessarily know what she is. She is solely a bioweapon who was never intended to be loved & she is unable to understand that others may utterly despised her.
