Anat

Anat was a guerrilla fighter and part of the human resistance opposing the Daleks from an alternate Earth future. She was the leader of the group that travelled back to the 20th century to kill Sir Reginald Styles.

After rescuing the Third Doctor and Jo Grant from the Daleks, she tried to convince him to help them kill Styles and prevent their timeline from coming to pass. Instead, he deduced that it was actually the guerrillas who had created their timeline in their attempt to prevent it. Anat then allowed the Doctor and Jo to return to the 20th century.
