Diana Goddard

Diana Goddard is a human female and victim of the Chrono Slayer, who killed and erased her from history.

In the original timeline, she was the personal assistant of Henry van Statten, billionaire inventor and owner of GeoComTex. Following an eventful encounter with a Dalek and the Doctor in 2012, Diana, disgusted by the ethical attitudes of her boss, overthrew him and took charge of GeoComTex, sealing the Vault away.

Seeking to disrupt the Web of Time, the Chrononatrix conlcuded that van Statten unopposed would have ultimately brought the Earth to ruin, and so sent the Chrono Slayer to eliminate Diana Goddard from the timeline.

As it turned out, though June's mark was wiped from history, she continued to exist after being slain in the form of a Neverperson, whom was absorbed into the Neverloff. When the Doctor Donna found her absorbed, her face was seen embedded into the Neverloff's belly.
