Madame Zodiac
In issue #285, Batman begins to experience strange blackouts, and Superman experiences a prophetic dream in which he witnesses Batman lying on an altar beneath the Zodiac Idol of Doctor Zodiac. Superman briefs Batman on his vision, but when he uses his X-Ray vision to check on Doctor Zodiac he notices that the criminal is still in prison. The issue reintroduces us to Madame Zodiac and reveals her first name to be Marissa, while also reintroducing Doctor Zodiac (Theodore Carrigan). Madame Zodiac reveals to Doctor Zodiac that she has begun testing Batman, and that she believes that Bruce Wayne is Batman. Superman and Batman consult with Zatanna and give her a couple of Doctor Zodiac's mystical Zodiac Coins hoping that she can use them to track down the Zodiac Idol. Zatanna loses control the moment she touches the coins, and mentions a "dark cloud" before eventually lapsing into a coma.
