 In the Post-"Crisis" DC Universe, the Roman Gods existed separately from the Greek ones after Darkseid tricked them into splitting up so they could be worshipped by two different cultures at the same time; only after the "War of the Gods" did the two versions merge again.So in effect, both Heracles and Hercules existed, and they merged into one being during John Byrne's run on the comic.A revamped Hercules reappears during the events of "One Year Later".
