The series idea had two ways: both animation and live-action combined or just pure animation. The episodes are set in several timelines to explain certain parts of the history before the events of the DigiDestined Saga. It will also connect the DigiDestined Saga and the Legendary Tamers Saga to each other. Despite episodes set in separate years, there are few characters who appear in every episode. And the story in set into both the real world and the Digital World. The miniseries has three story arcs.
The development of the miniseries started at the same time with the Legendary Tamers Saga films. The Arc 1 was released in November 2015. The Arc 2 was released in January 2016. The Arc 3 was canceled, but the planned plot points were revealed in March 2016.
The series is based original ideas, combined with adapted plot points from certain real-life films and common Digimon mythology.

- The Arc 1 includes the only full appearances of all Seven Great Demon Lords. It is the only part of the Cinematic Sagas continuity that includes the appearance of fourteen members of the Guardian Knights, including those who will never be seen in the films. Using Lucemon and the Celestial Digimon is the only plot element from Digimon Frontier to have ever been adapted into the Cinematic Sagas.
- The Arc 2 includes plot points of inspired partly by movies Digimon Adventure: Our War Game! and Digital Monster X-Evolution, through use of Diablomon (Diaboromon in English dub) and X-Antibody. X-Antibody was originally never meant to be used in the Cinematic Sagas, but Dorumon's appearance in the series caused a change of plans.
- The Arc 3 includes plot points which explain several plot holes of the films. It is also the only arc that isn't a full prequel, since the events of its last episodes happen during the events of the films rather than before them.
- There was once two different prequel ideas. One of them was an anthology film about from the birth of the Digital World to the battle against the Great Demon Lords, and the other one was a drama series taking place solely in the human world, with Robert Harmon, Kevin Harmon, Audrey Clinton, and Martin Harmon as the main characters. DigiPast Chronicles was born as a combination of these two ideas. The Arc 1 is based on the anthology idea and the Arc 2 is based on the drama series idea.
- The series was left only 13 episodes long in order to make sure the unreleased film ideas won't be delayed for too long.
