"Even today, there are those who risk their lives to adventure. They overcome all troubles to secretly protect dangerous treasures. Adventurers!"
Gōgō Sentai Boukenger (Rumbling Squadron Adven-ger note A combination of bōken (adventure) and "ranger") is the thirtieth program in the Super Sentai franchise, airing from 2006 to 2007.SGS ("Search Guard Successor") is a private philanthropic organisation dedicated to the preservation of historical artifacts and treasures. The most dangerous of these relics, possessing powers beyond that of modern human technology, are designated as "Precious".To stop these artifacts from falling into the wrong hands, SGS have created the GoGo Sentai Boukenger: an elite team of Adventurer Archaeologists who channel the spirit of adventure as they search the four corners of the globe for the mythical Precious. Opposing them are the "Negative Syndicates", a designation that SGS gives to any hostile organisation that seeks to misuse the Precious for their own ends.Boukenger is based mostly on treasure hunting and the tales based on it as well as bringing some unique ideas to forefront such as different villain factions. There is also a bit of a personality change between the Pink and Yellow members as explained below.
Questers: The Questers were originally two members of the demonic Ashu Tribe, Gai and Rei, who were killed but later resurrected by Gajah with new cybernetic bodies. However, they soon rebelled against him and became their own Negative Syndicate. They possess no Mooks or Monsters Of The Week, but are individually the most powerful fighters of the four Negative Syndicates and occasionally create Giant Robots called Quester Robos.
Evil Plan: The "Negative Syndicates" and their plans for the "Precious"
Eyecatch: The camera pulls out to the Boukengers spinning around, stopping to show Satoru in Ranger form shooting the SurviBuster once. After the break, the camera passes the Boukengers in civilian form while they look at the camera, stopping with Satoru looking at the camera.
Humongous Mecha: Boukenger, for awhile, held the Sentai record for "Most Mecha Combined" at 10note At least until Engine Sentai Go-onger comes along two years later with its Engine-O G-12... (both Ultimate Daibouken and Voyager Daibouken), with a 12-combination (Ultimate Daibouken with Police and Aider added on the back) seen in a bonus video.
In the Name of the Moon: Involves invoking their "title" and then crying out what color they are. Often enough, a speech will be involved with this somehow.
Satoru: The fiery adventurer! BoukenRed!
Masumi: The fast adventurer! BoukenBlack!
Souta: The high-up adventurer! BoukenBlue!
Natsuki: The strong adventurer! BoukenYellow!
Sakura: The deep adventurer! BoukenPink!
Eiji: The dazzling adventurer! BoukenSilver!
Satoru: The endless adventure spirits!
All: GoGo Sentai Boukenger!
Law of Chromatic Superiority: Averted with this season: The Acceltector, which is usually the type of equipment exclusive to this trope, is usable and used by all team members. Also in the mecha department, everyone has 3 mecha exactly after everything is revealed.
Make My Monster Grow: Dark Shadow can invoke this trope directly with their Shikigami. Ryuuwon can also do it, but when he's the villain most of the time it's on account of that episode's Precious.
Monsters Of The Week: Dark Shadow's Shikigami and Jaryu Tribe's Jakuryu. The Questers would have their new Humongous Mecha, and when Gajah showed up the Precious of that episode itself was usually some kind of monster.
Action Bomb: One filler episode (Task 39) is notorious for having the Rangers try to defuse one of these by literally pacifying it. The girls dress up as Meido while the guys perform Manzai.
All Myths Are True: Although some reveal a previously unknown side to the legend. Case in point, the episode with Cinderella's glass slipper...
All Your Powers Combined: During Boukenger vs. Super Sentai, when the main five Boukengers are having trouble defeating Chronos, AkaRed asks Eiji and the five guest heroes to transfer a part of their spirits into him so that he could help power-up DaiVoyager.
Alphabetical Theme Naming: Satoru, Souta and Sakura are the three senior members; Masumi and Natsuki (and then Eiji) are the rookies.
Arbitrary Skepticism: At the beginning of the Christmas episode, nobody believes Satoru when he says a miniskirt Santa fell from the sky and smashed the cake he bought. Keep in mind that these are the same people who had dabbled with people like (and related to) The Pied Piper of Hamelin, Princess Kaguya, Issunboshi, Cinderella, Momotaro etc. And yet they say that the idea of Santa Claus existing, let alone not being like everyone thinks, is too much for them to grasp?!
Chew Toy: When Satoru is cursed with bad luck, he gets hit by a bus, a crane falls on him, chunks of building fall him, he catches on fire from the explosion that follows the roll call, a appears from nowhere rolls over him, and gets struck by lighting.
Further, the Super Hero Time block that Kamen Rider and Super Sentai share featured a Massive Multiplayer Crossover between Kamen Rider Kabuto and this series to signify that the other show was starting. These can be found on fansubs of Kabuto's episodes... and must be seen to be believed.
Dark Side: Yaiba keeps on telling Masumi to fall into it.
Eiji, who acts as a catalyst to this, goes through some defrosting of his own as he starts out the brooding loner, but warms up to his new family enough to address Sakura as ''Nee-san'' habitually.
Determinator: The remaining five Boukengers fighting to free Natsuki from Ryuuwon and the Questers' clutches in Task 34. Masumi even gains a Crowning Moment Of Awesomeduring his henshin sequence: he brushes his Accellular against a bullet fired by Ryuuwon. And the bullet is deflected, to boot.
Dub Name Change: In the Korean version the Boukengers become Keine (Satoru), Ray (Masumi), Ryuu (Souta), Hannah (Natsuki), Yumi (Sakura) and Jackie (Eiji).
Elemental Powers: The Boukenger's weapons are each powered by a different element.
Ryuuwon turned out to be one very close to the end. The hints come somewhat earlier though.
Handsome Lech: A mild version; Souta. He's got lots of girlfriends. The behavior also surfaces a tad when he's facing off against Shizuka.
Heroic BSOD: Played for laughs. Satoru gets one after failing an adventure school's entrance exam and sat moping at a corner throughout the first half of the episode, as Eiji and Masumi tease him for 3/4 of the episode. Actually he did pass, but the proctors made a mistake.
If It Swims, It Flies: GoGoMarine uses GoGoGyro to cleverly avert this. GogoVoyager resembles a battleship but classifies as an amphibious vehicle by way of having wheels.
Ineffectual Sympathetic Villain: Shizuka, obviously, but Gajah too. Maybe it's because his actor is an old man, or because he puts more effort into his schemes than the other groups, but it's hard not to feel bad for him when they fail.
Japanese Pronouns: Eiji tends to use the very arrogant "Ore-sama" as first person pronoun, but uses the more moderate "Ore" when feeling less secure. He is also in general very impolite: He uses towards the spirit of his dead mother "Anta" as second person pronoun, which is normally rather hostile, even though he uses it in a scene where he is reconciled with his mother.
Massive Multiplayer Crossover: Pulled off with the movie Boukenger vs Super Sentai. This crosses the series over with Magiranger (from which Tsubasa, Hikaru - along with his ainde Smoky - and Meemy were drawn), Dekaranger (from which Tetsu was drafted), Abaranger (from where came Asuka), Hurricaneger (from which Nanami and Furabijou returned) and even Gaoranger (from which no heroes came, but villainess Tsuetsue made her appearance) for one massively insane storyline.
One-Winged Angel: Most of the main villians have it happen at some point, though Yaiba's is just his faceplate moving aside to reveal a different faceplate. A bit of a letdown after the big dramatic "nobody has seen my true face and lived" thing.
Outside-Context Villain: Every now and then you get something that doesn't originate from the Negatives, although Gajya will attempt to control some of them.
Panthera Awesome: the Ashu's entire schtick, which seeps into their Quester forms.
Punny Name: Each Boukenger has a name that has to do with his/her respective color:
Akashi Satoru (the Kanji for Satoru can be read as akatsuki or "red moon"/dawn)
Masumi (sumi = black ink)
Souta ("Sou" can be read as ao or blue)
Natsuki (Na can mean "cole blossom" and tsuki can mean "moon"; both of these are often seen as being yellow)
Sakura (cherry blossoms, which are pink)
Eiji (pronounced A-G, like Ag, the chemical symbol for silver)
Rags to Riches: A subversion of the Snow White type; Natsuki is the princess and last living member of the Lemurian kingdom. Since said kingdom is long gone, she has nothing left to rule, which is good since her parents just wanted her to live a normal life anyway.
Shout-Out: Aside from the design Shout-Out listed above, this series was also the 30th Anniversary of the franchise. The ending of almost every episode, starting with episode 4, had a 30-second tribute to a Super Sentai crew of years past - and then went on to make special mentions of firsts in the franchise, such as the most notable Sixth Ranger characters in addition to the first. It ended with Juken Sentai Gekiranger, the next season, as the last segment.
Of note, the only series whose mecha got no 'enemy representative' is Goggle V. However, Boukenger still gives them Shout-Out in form of any of their mecha's completion quote, "(insert mecha name here), Gattai Kanryou (Combination Complete)!"
The arc where Natsuki's origins are revealed contains plenty of connections to previous yellows. First off, she's the princess of Lemuria, which is the civilization represented by Goggle Yellow. And her parents? Kirin Ranger and Mega Yellow.
The powerful artifacts referred to as "Precious" and all kinds of evil characters are after them. Sound familiar?
Stealth Pun: Kaze no Shizuka as a truck going nuts when BoukenSilver's hand lands on one of her headlights.
Thememobile: the first five GoGoVehicles (Dump [truck], Formula [1 racing car], Gyro [kind of a helicopter], Dozer and [Sub]Marine) apparently have nothing in common apart from their windshields looking like the ones on our heroes' helmets, but vehicles appearing later start to take on themed motifs:
Drill, Shovel, Mixer, Crane - construction vehicles
Jet's ability to airlift smaller vehicles place it somewhere between construction and rescue
Fire [fire truck], Police, Aider [ambulance] - rescue service vehicles. Notable as the first time the designated pilot BoukenSilver shares none of their motif (or even base colors) in his design.
Commander, Carrier, Figher, Attacker, Roller (and their combined GoGoVoyager form) - armed combat vehicles. Notable as the first time Super Sentai has used such vehicles since Maskman, in lieu of Japan's non-militant politics (see Kaiju Defence Force.)
Theme Music Power-Up: When Start Up! ~Bonds~ kicks in, you just know someone's gonna get their ass handed to them.
Theme Naming: Each Boukenger's family name is taken from that of a Japanese explorer.
There Is No Kill Like Overkill: Though Ultimate DaiBouken would later be overshadowed in terms of component parts, using it on normal-sizedmooks (and friends) is overkill. All by Natsuki.
