Victoria Waterfield

One of the Second Doctor's companions and Edward Waterfield's daughter.  She was taken hostage by the Daleks, then joined the TARDIS' crew on Skaro after her father's death.  Victoria helped the Second Doctor and Jamie against   the Cybermen, the Yeti, the Ice Warriors, Salamander and the intelligent seaweed creatures, which turned out to be vulnerable to the ultra-sounds in her voice.   Victoria eventually left to stay with the Harris family, who took her in as a daughter.
