Since Weisman et. al. claim to be distilling the best of the DC comic stories, here are the potential death candidates simply based on the comics: No core supporting character of the Batman franchise has ever died. Even Bruce Wayne's supposed death in Final Crisis was a time travel story.
 * 1) All the New Gods (killed off in Death of the New Gods and Final Crisis)
 * 2) Artemis (killed in Teen Titans Annual during the Harvest)
 * 3) Aqualad (written out of continuity after Flashpoint)
 * 4) Flash/Barry Allen (killed by Anti-Monitor in Crisis on Infinite Earths)
 * 5) Flash/Bart Allen (killed by Rogues at the instigation of Inertia in Flash v4)
 * 6) Flash/Wally West (written out of continuity after Flashpoint)
 * 7) Martian Manhunter (killed by Libra in the Prelude to Final Crisis)
 * 8) Miss Martian (killed in the events of The Brightest Day)
 * 9) Superboy (killed by Superboy in Infinite Crisis)
