Legends of the Dark Knight 100-Page Super Spectacular was an ongoing comic book featuring Batman stories by many different creative teams. All the stories were intended to be “continuity free” and do not fit into the canon of any of the mainstream DC universes (Prime Earth, New Earth, Earth-One or Earth-Two). This series was digital first, meaning the stories were first available online, and then later published on paper in this series.
