The 30 Sentai Encyclopedia (2006)

The 30 Sentai Great Encyclopedia is a series of featurettes that aired at the end of each episode (Task) of Boukenger that honors each of its predecessors in the Super Sentai franchise, starting with Task 4. They looked back at each of the 29 previous teams, referencing various items within the older shows, and later on, wearing the costumes and using other props from the series, such as the "civilian" clothing. After covering themselves, they start a new series of segments called the Special Files that cover milestones from the "First Sentai Team" to the "First Sixth Hero" and then the "First Multi Gattai", playing an insert song from the respective series. The show's final segment covered its successor Juken Sentai Gekiranger.

The Encyclopedia is not included as part of Boukenger in the DVD release or on streaming.
