Originally from 1980s London, troubled teen Ace (real name ‘Dorothy’) met the Doctor on Iceworld, where she had been transported as part of a trap by an ancient evil called Fenric. Favouring home-made explosives, a baseball bat and her ghetto-blaster, she was a marked difference to Mel. As well as fighting Cybermen and Daleks singled-handedly, she faced the demons of her past and the reality of hating her mother. Righteous and brave, Ace had absolute faith in the Doctor, and developed into a bold young woman during her travels. Many conflicting reports exist as to what happened to Ace after her travels in the TARDIS, but Sarah Jane Smith later recalled that a “Dorothy something” raised billions through her foundation A Charitable Earth.
