The DC Comics co-publisher suggested that the minor Watchmen character may be highlighted in one of the forthcoming prequels, reports ComicBook.com.
"Moloch is such a strong character, you wouldn't be surprised if he shows up in his own book at some time," DiDio told fans at London's Kapow! Comic Convention.
He had previously said that more Before Watchmen tie-ins than previously announced could be forthcoming.
DiDio also described the controversial project as a "love letter" to Alan Moore's creations.
Moloch appeared briefly as a retired villain in the original 1986 limited series, his death serving as part of the overarching plot of the comic's villain.
Before Watchmen will launch in June.
