GoGo Sentai Boukenger

Plot summary

Powerful relics known as the Precious appear throughout the world. Noticing these relics' power, various Negative Syndicates wish to take the Precious for themselves and use them for evil ends. To make sure that the Precious do not fall into the hands of the Negative Syndicates, the Search Guard Successor Foundation (SGS) has developed its own special operations team, the Boukengers, whose mission is to collect the Precious and thwart the Negative Syndicates.

Negative Syndicates

Not much is known about the Negative Syndicates (ネガティブシンジケート, Negatibu Shinjikēto) other than that they are individual organizations whose respective leaders, foot soldiers, and monsters try to steal the Precious and use them for evil deeds. Although there is some animosity between the member groups, they occasionally work together.

The Goodomu Civilization (ゴードム文明, Gōdomu Bunmei) is the first of the Negative Syndicates.

High Priest Gaja (大神官ガジャ, Daishinkan Gaja): The sole survivor of the Goodomu Civilization. He intends to restore Goodomu its former glory by retrieving the Precious lost to them over the thousands of years they spent in slumber. Goodomu was the first and last Negative the Boukengers had to deal with.

The Jyaryu Clan (ジャリュウ一族, Jaryū Ichizoku) are the second of the Negative Syndicates who seek to destroy mankind and make the Earth more suited to their reptilian bodies.

Creator King Ryuoon (創造王リュウオーン, Sōzōō Ryūōn): Once human, Ryuoon is the leader of the Jyaryu Clan. Ryuoon returned in Kaizoku Sentai Gokaiger episode 21, the tribute to Boukenger.

The Dark Shadow (ダークシャドウ, Dāku Shadō) is a ninja clan that is the third of the Negative Syndicates. Under Gekkou of Illusion, they use old and new items to create monsters called Tsukumogami (ツクモガミ) to help them gather Precious for profit. Dark Shadow resumed its wicked ways in the epilogue.

The Questers (クエスター, Kuesutā) are the fourth of the Negative Syndicates. Formerly of the demonic Ashu Tribe (アシュ族, Ashu Zoku), Gai and Rei were revived as robots by Gaja's Goodomu Engine after they were destroyed by the Boukengers and Eiji.

Films

Theatrical

Episode 18 of Kamen Rider Kabuto showed a short preview for the Boukenger movie, and starting with Task 19, Boukenger showed its own previews. 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 theatres on August 5, 2006, doubled-billed with Kamen Rider Kabuto: God Speed Love. 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's ideals, the prize is more treacherous than the path to it.

Other Specials

Boukenger vs. Super Sentai

As with Gaoranger before it, Boukenger features a team-up special featuring five past Sentai members and a new hero, entitled GoGo Sentai Boukenger vs. Super Sentai (轟轟戦隊ボウケンジャーVSスーパー戦隊, Gōgō Sentai Bōkenjā tai Sūpā Sentai).

The villain for this special, Time Demon Chronos (時の魔神クロノス, Toki no Majin Kuronosu), abducts all of the Boukenger, save for Eiji, into an alternate dimension. A warrior known as Aka Red contacts Eiji on Earth and provides him with a book that holds the names of all of the past warriors. He seeks the assistance of Tsubasa Ozu (Magi Yellow of Mahō Sentai Magiranger) at a boxing match, Tekkan "Tetsu" Aira (Deka Break of Tokusou Sentai Dekaranger) while he is undercover, Asuka (Abare Black of Bakuryū Sentai Abaranger) taking care of his daughter on Dino Earth, and Nanami Nono (Hurricane Blue of Ninpuu Sentai Hurricaneger) at her concert. They then fight Chronos who has purchased Goodomu Engines from Gajya to bring back Furabiijo from Hurricaneger, revive Duchess Org TsueTsue from Hyakujuu Sentai Gaoranger and Sorcery Priest Meemy of Magiranger. 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). The events of the movie take place between Tasks 42 and 43.

Gekiranger vs. Boukenger

In Juken Sentai Gekiranger vs. Boukenger (獣拳戦隊ゲキレンジャーＶＳボウケンジャー, Jūken Sentai Gekirenjā tai Bōkenjā), the Gekiranger team meets up with the team from GoGo Sentai Boukenger. The DVD was released on March 14, 2008, for rental and March 21, 2008, for purchase. This is the first team-up to be in wide-screen, appropriate as Boukenger and Gekiranger were the first Sentai series to be themselves shown in wide-screen. The events of the movie take place between Lessons 35 and 36. The film is dedicated to Machiko Soga who died in 2006

Gozyuger vs. Boonboomger
