Precious

Precious(プレシャス,Pureshasu) are the dangerous treasures that the Boukengers and Negative are fighting over. For a relic to be considered a Precious, it must be physically or technologically superior to any current human (or SGS-related) technology. The hand-held Accellular henshin devices use their half-open Scan Mode to determine the "Hazard Level" of each relic; the higher the number, the more important or dangerous the Precious is. Each relic that ends up in the Boukengers' hands is placed into a box that materializes from a card-like device.

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(スペシャルファイル,Supesharu Fairu) that cover milestones from the "First Gattai Robo" to the "First Sixth Hero" and then from the "First Multi Gattai" to the "Extra Heroes", playing an insert song from the respective series. The show's final segment (Task 48) covered its successor Juken Sentai Gekiranger.

The movie is titled GoGo Sentai Boukenger the Movie: The Greatest Precious(轟轟戦隊ボウケンジャー THE MOVIE 最強のプレシャス,Gōgō Sentai Bōkenjā Za Mūbī Saikyō no Pureshasu), which occurs between Tasks 28 and 29. It was released in theaters on August 5, 2006. A mysterious being called Muse(ミューズ,Myūzu) awakens, announcing the Precious to whoever gets to her first, causing a 5-way confrontation between the Boukengers, Gajya, the Jyaryu, Dark Shadow and the Questers. Even Satoru's father, Kouichi(虹一,Kōichi) is involved. But as Satoru learns while dealing with his father ideals, the prize is more treacherous than the path to it.
GoGo Sentai Boukenger vs. Super Sentai

While the remaining Boukengers are in the other dimension, they meet up with Hikaru (Magi Shine of Magiranger) and Smoky, his cat genie, and try to find a way to escape. When Chronos turns Meemy, TsueTsue, and Furabiijo into a staff-like Precious with a Hazard Level of 666, Aka Red becomes a vessel for the six Sentai Spirits and allows for DaiVoyager to become Burning Legend DaiVoyager(バーニングレジェンドダイボイジャー,Bāningu Rejendo Daiboijā).
