Eve (The Mad Woman in the Attic)

Eve was a member of an unknown race of aliens which were destroyed during a Time War.

Biology
Eve was a humanoid child, with red skin, eyes and hair. She had large, extended ears.

Eve's race could read timelines and control objects from a distance. They also had the ability to possess and control humans. A juvenile of the species could be strong enough to manipulate objects for a short while but would eventually be burnt out by the energy. Their powers were at least partially linked to their technology, as demonstrated by Eve's Ship absorbing excess energy from her after she tried to control too many people and machines.

Biography
Eve's race was being destroyed in a war between two great powers (presumably the Last Great Time War between the Daleks and Time Lords, as she says her planet was "Exterminated"). Their ability to read the timelines had made them a target for elimination; it is not stated which side committed the genocide, although it is presumed to be the Daleks as Eve said they were exterminated. Eve was smuggled onto a ship by her parents, who sent her away to Earth as an evacuee. Her ship crash landed on a beach. Harry Stevens, the caretaker of a nearby funfair, found Eve and, under orders of Ship, kept her in the haunted house away from civilisation for her to play games until Ship rebooted.

When the funfair was closed down, Eve got lonely and kidnapped and possessed four Humans to play with her in the fair. When Samuel Lloyd came to the funfair, his mind was read by Ship, who found the information about Sarah Jane Smith and her friends, who Ship believed could help. Ship made Samuel contact Rani Chandra and bring her to the fair. When Rani Chandra came to investigate the funfair on her own, she stumbled across Eve. When Rani persuaded Eve to leave the haunted mine, she tried to control too many people and rides, and began to burn herself out through an excess of energy. Helped to the crash site at the beach by Sarah Jane's companions and Harry, her energies were absorbed by Ship and her health was restored.

With Ship's engines repaired, Eve departed Earth to explore the universe, taking along Harry and Samuel. She and Sam later had a son, Adam, who appeared human. (SJA: The Mad Woman in the Attic)
