- You may be looking for "Goldilocks," the sentient Black Void.
Goldilocks was leader of the human animatronic forces on Winkle's Wonderland. She used the fairy, Tinkerbell, to possess members of the opposing forces such as Captain Duck and Corporal Dodo. She was modelled on Walton Winkle's daughter.
While dealing with the aftermath of the explosion of anti-time, the TARDIS created a series of holographic projections, taken partly from reality and partly from the memories of the Eighth Doctor, Charley Pollard and the TARDIS itself. One such projection was the battle in Winkle's Wonderland as the TARDIS was looking for information on the Divergence. Inside this projection, it placed Charley in the role of General Mouse and itself in the role of the Captain Dodo. The projection of Goldilocks was created using the image of the Seventh Doctor's companion Melanie Bush. (AUDIO: Zagreus)
