Eve 8 was a clone from the Eve Series of clones created in the Lichfield Experiment. Like the other Eve clones in the original run she was extremely intelligent, had extraordinary strength and suffered from homicidal and suicidal tendencies.
After the closure of the Lichfield Experiment she was housed at the Whiting Institute for the Criminally Insane with the other surviving clones in her series but escaped into society. In 1994, after Eve 9 and Eve 10 were added to the menagerie of clones at the Whiting Institute, Eve 8 returned posing as a doctor. It seemed as though she had some kind of fiendish plan in mind for her remaining siblings (TXF: "Eve").
