Madame Zodiac
In issue #286, Wonder Woman takes Zatanna away to Paradise Island for medical treatment, and Madame Zodiac reveals that she freed Doctor Zodiac from prison and left a mystical illusion in his place. She freed him because she had his Zodiac Idol, but wanted access to the Zodiac Coins that provide its power. She uses Doctor Zodiac's mystical connection to the twelve Atlantean coins to steal them from the coin collectors who currently own them. Now possessing all twelve coins she is able to activate the Zodiac Idol. It is also revealed that Theo (Doctor Zodiac) and Marissa (Madame Zodiac) are now romantically involved. Theo discovers that she has used the Zodiac Idol to contact an ancient other-dimensional evil she refers to as her "master". Meanwhile, a dark cloud begins appearing all over the United States in various cities including Metropolis and Gotham City. Everywhere the cloud appears it inspires hate crimes, including the defilement of a Jewish synagogue, and the near lynching of Lucius Fox. Meanwhile, Theo (Doctor Zodiac) is becoming concerned as Madame Zodiac's shadowy master grows in power. Elsewhere, Green Arrow (Oliver Queen) confronts a werewolf, and Hawkman (Katar Hol) defeats what appears to be a vampire. An unstoppable phalanx of zombies attack a GCPD barricade in Gotham City, but are stopped by Superman. At the end of the issue, Madame Zodiac states that her master is now powerful enough to possess his chosen host's body.
