Dark Lucifer (ダークルシファー Dāku Rushifā) is the final Dark Ultra to be created by Dark Zagi, appearing in 2012, three years after his master's death. Dark Lucifer was actually meant to be the final antagonist of Ultraman Nexus but due to the series' low viewership, Zagi was instead the final boss. He was originally meant to be the revived form of Zagi, but is instead a final creation thanks to the novel.
