Ann Margaret would be cruel in her catfight with Lindsay Wagner and seriously beat her up.
Elvira would have a very low tolerance for Loni Anderson and get seriously pissed off if Loni gave her any trouble. Elvira would demolish her opponent.
Cathy Crosby would get increasingly nasty with Joey Heatherton whilst beating the weaker woman.
Goldie Hawn and Barbara Bach is an extremely difficult one to call, perhaps Goldie could win this?
Raquel Welsh would aggressively and cruelly fuck up Sharon Tate, no question.
Britt Eckland would rag Annette Funicello by the hair and drag her around until Anette began to cry in pain.
Stephanie Powers fighting Linda Evans would be an even fight, perhaps both women getting increasingly frustrated and Stephanie resorting to choking Linda or scratching her face in order to win by submission.
