Moonshadow and
Brooklyn Dreams. He began writing for DC in the late 1970s and rose to prominence with characters such as the Justice League revamp of the 1980s, a franchise that earned him an Eisner Award in 2004 for Best Humor Publication. He has written every major character at DC and Marvel, using that experience for a successful foray into animation writing including episodes of
Justice League Unlimited and
Batman: The Brave and the Bold.
