Angora is the secondary antagonist of Avengers : "The Hidden Tiger". She sent with Peters and Dr. Manx, many cats to kill all Congrest members of P.U.R.R.R. then to take the entire country in hostage with their army of cats and become immensely rich.
Fortunately, Steed and Emma succeeded to fail their plan. Angora is finally knocked out by Emma Peel whereas she tried to flee.
She sent in jail offscreen (with Peters knocked out earlier by Steed before he was captured by Manx and Angora, whereas Manx died in a car accident).
