Ace

"Do you feel like arguing with a can of deodorant that registers nine on the Richter scale?"

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 homemade 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.
