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.

Characters

SGS

The Search Guard Successor Foundation (サージェス財団, Sājesu Zaidan; SGS) collects artifacts known as Precious (プレシャス, Pureshasu) with help from the eponymous Boukengers. They are led by Mister Voice (ミスター・ボイス, Misutā Boisu), who serves as a liaison to the main SGS headquarters, and assisted by Morio Makino (牧野 森男, Makino Morio), who is the technical specialist of SGS and creator of the Boukengers' GoGo Vehicle (ゴーゴービークル, GōGō Bīkuru) mecha.

Each primary member carries an Accellular (アクセルラー, Akuserurā) cellphone as their transformation device along with a Survi-Buster (サバイバスター, Sabaibasutā) handgun, which can be reconfigured into the Survi-Blade (サバイブレード, Sabaiburēdo) sword, and a multipurpose Scope Shot (スコープショット, Sukōpu Shotto) device, which can combine with a Survi-Buster to access the latter's Sniper Mode (スナイパーモード, Sunaipā Mōdo), as their sidearms. Any one of them can also be equipped with the Accel Tector (アクセルテクター, Akuseru Tekutā) armor to wield the Dual Crusher (デュアルクラッシャー, Dyuaru Kurashā), which can switch between its Mixer Head (ミキサーヘッド, Mikisā Heddo) and Drill Head (ドリルヘッド, Doriru Heddo) modes.

Satoru Akashi (明石 暁, Akashi Satoru)

Satoru leads the team with a calm expression and a fire in his heart. He mostly battles Ryuuwon.

As the "Fiery Adventurer" (熱き冒険者, Atsuki Bōkensha), Bouken Red (ボウケンレッド, Bōken Reddo), Satoru wields the Bouken Bo (ボウケンボー, Bōken Bō), which can be reconfigured into the Bouken Javelin (ボウケンジャベリン, Bōken Jaberin). His personal GoGo Vehicles are GoGo Dump (ゴーゴーダンプ, Gōgō Danpu), GoGo Jet (ゴーゴージェット, GōGō Jetto), and GoGo Commander (ゴーゴーコマンダー, GōGō Komandā).

Masumi Inou (伊能 真墨, Inō Masumi)

Masumi is only part of the Boukengers to repay his debt to Satoru for saving his life. He has a personal vendetta against Dark Shadow member Yaiba of Darkness (闇のヤイバ, Yami no Yaiba).

As the "Fast Adventurer" (迅き冒険者, Hayaki Bōkensha), Bouken Black (ボウケンブラック, Bōken Burakku), Masumi wields the Radial Hammer (ラジアルハンマー, Rajiaru Hanmā). His personal GoGo Vehicles are GoGo Formula (ゴーゴーフォーミュラ, Gōgō Fōmyura), GoGo Crane (ゴーゴークレーン, GōGō Kurēn), and GoGo Carrier (ゴーゴーキャリアー, GōGō Kyariā).

Allies

Shiro Masaki (柾木 紫郎, Masaki Shirō)

Phantom Thief Selene (怪盗セレネー, Kaitō Serenē)

She had been seeking the treasures from The Tale of the Bamboo Cutter, crossing the Jaryuu Clan while getting her fourth treasure, the Dragon's Neck Orb. She could have been Princess Kaguya herself.

Magi (マギ)

An elder from the Water Metropolis who didn't want to see any more of his people perish in the search for the Aqua Crystal.

Ragi (ラギ)

Magi's apprentice. Once a "Water human", he intended to finish what his father started to restore the Water Metropolis. He sacrificed his humanity to survive without water by discarding the "Proof of Water" crystal on his tiara (which Ryuuwon crushed) and was transformed into a Wicked Dragon by Ryuuwon, who used him to find the Aqua Crystal. Ragi's Wicked Dragon form's design is based on Bakuryū Sentai Abaranger's Bachycelonagurus.

Karato Takaoka (高丘 漢人, Takaoka Karato)

Eiji's father who was killed fighting Gai.

Kei (ケイ)

The only female Ashu and Eiji's mother as a result of her and Karato's sharing of forbidden love.

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

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

The Combatant Curse (戦闘員カース, Sentōin Kāsu) are ash-colored stone beings are the foot soldiers for the Goodomu Civilization, summoned from stone. They wield torches that can change into sickles and have a noticeable healing factor, as Souta found out the hard way when he injured his hand punching one in the chest with full force. Fortunately, this healing factor cannot save them from those more powerful than they are. Both Dark Shadow and the Jyaryu Clan use Curse occasionally. The Curse's design is based on Chōriki Sentai Ohranger's Tackle Boy.

The Jaryuu 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 Ryuuwon (創造王リュウオーン, Sōzōō Ryūōn): The leader of the Jaryuu Clan who was once human. Ryuuwon returned in episode 21 of Kaizoku Sentai Gokaiger episode 21.

Dragonoid Soldier Jyaryu (竜人兵ジャリュウ, Ryūjinhei Jaryū; 2-49) are dragon-like warriors created by Ryuoon using his own blood and machinery. They wield swords and can summon hundreds of poisonous red lizards from their bodies. They are fewer in number when compared to the Curse, but more powerful. They are also capable of speech. The Jyaryu's design is based on Kyōryū Sentai Zyuranger's Dragon Caesar.

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, Gajah, the Jaryuu Clan, Dark Shadow, and the Questers. Even Satoru's father Kouichi 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 Gordom Engines from Gajah 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).
