• During an attempt to protect the Three Headed Dragon of Darkness from Ryuuwon, the Precious of darkness lands in Masumi's control, allowing for his latent darkness to emerge. (Task 45)
• Yaiba tempts Masumi to fully awaken his darkness to use the Three Headed Dragon, but as a means to force a mass of darkness from space to Earth for those who can control it to rule.

• Having reached the limit of his powers, Ryuuwon makes a final drive towards reaching Pandora's Box but is beaten to the Precious by Gajah; the Gordom Priest absorbs the energy within the box to create his ultimate minion: Desperado. Believed to be fully defeated, Ryuuwon kills himself, leaving behind a helmet that the Boukenger claim as a Precious due to it's unnatural power. Upon taking Ryuuwon's helmet to SGS's Precious Bank, Ryuuwon reveals it as a deception in order to become reborn into a dragon via the Egg of Lemuria.

• From within the rubble of the now-destroyed Precious Bank, Gajah reclaims the Heart of Gordom, which he absorbs to begin a mutation into the Gordom God before returning to Gordom Island to allow Desperado to reclaim the Brain of Gordom. SGS shuts down all Parallel Engines as a failsafe after the destruction of the Precious Bank and Gajah's maneuvers.

(Task 48)
• The Boukenger return to Gordom Island and face down Gajah, who has evolved due to the effect of the Heart of Gordom. Using the full extent and abilities of the Parallel Engines and all 18 Go Go Vehicles, the team puts a stop to the ancient being, who appears killed but is merely defeated, choosing to return to cryogenic stasis until the world no longer has such nuisances. (Final Task)
