Eveline

Eveline looks like a harmless ten-year-old girl, but her origins are anything but. Known by an alternate title, E-001, Eveline was created by a bioweapons research group as an experiment in harnessing a newly designed fungus. Everything about her was intentional, from her age (which made her seem less suspicious) to her placement with Ethan's wife Mia, who posed as a parental guardian. The fact that Eveline was created to destroy drives much of her character, ultimately leading her to manipulate her powers to fulfill her desire to belong.
