15MARCH OF THE BLACK QUEEN
In the famous "Dark Phoenix Saga", Jean Grey falls victim to Jason Wyngarde (Mastermind), a prominent member of the power-hungry Inner Circle of the Hellfire Club. Wyngarde uses his powers, which have been enhanced by unscrupulous telepath Emma Frost, to make Jean fall in love with him. After months of careful manipulation, Jean is firmly enough under Wyngarde's control that she betrays her fellow X-Men to the Inner Circle.
Adopting the name the Black Queen, Jean knocks out her friends and stands passively by while they are chained up and, in Cyclops' case, nearly killed. But like we said: Phoenix is one of the most powerful women in comics. She inevitably breaks free of Wyngarde's control, and once she does... well, let's just say the queen was not amused.
