In order to obtain the Greatest Treasure in the Universe, the Gokaigers must unlock the Greater Powers (大いなる力, Ōinaru Chikara) of the previous 34 Super Sentai teams before them. Each Greater Power they hunt for has an associated lesson with it.
By unlocking the Greater Power of a previous team's Ranger Keys, the Gokaigers can access special powers, often activated with GokaiOh, based on the previous Super Sentai teams' mecha; or special powers that power up GokaiOh through gaining approvals from a member of the past Super Sentai teams. Most of the powers manifesting as mechas are completely redesigned and don the Gokaigers' symbol. The unlocking of a Greater Power is signaled when the Ranger Keys of the team that has been unlocked start to glow.
Navi states that some Greater Powers are useless after obtaining the Carrangers' Greater Power. During the events of Gokaiger Goseiger Super Sentai 199 Hero Great Battle, the Gokaigers obtain eleven Greater Powers from past Super Sentai teams (Gorenger, J.A.K.Q, Denziman, Goggle-V, Dynaman, Bioman, Turboranger, Dairanger, Boukenger, Go-Onger, and Goseiger).
Aside from the Gokaigers, Basco managed to capture five Greater Powers into his possession (Sun Vulcan, Changeman, Flashman, Maskman, and Fiveman). Eventually, the search for the Greater Powers ended with the Gokaigers in possession of all 35 along with the Greatest Treasure in the Universe itself after they defeated Basco and took his five Greater Powers. Ep. 48: The Fated ShowdownEp. 49: The Greatest Treasure in the Universe
Variblune (バリブルーン, Bariburūn): The Variblune was the base of operations for the Gorengers. Although it was destroyed and replaced with the Varidreen, it returns to combine with GokaiOh to form Goren GokaiOh (ゴレンゴーカイオー, Goren Gōkaiō), and uses the Gokai Hurricane Cassiopeia for a finisher.
Before that, after they gained the Magirangers' Greater Power of MagiDragon, Luka (Gokai Yellow) tried to summon the Greater Power of JAKQ, which, seeing as how the Magiranger's Greater Power was MagiDragon, guessed was the J.A.K.Q. Blitzkrieg Dragon, but nothing came out of GokaiOh. The Gokaigers soon realised that they would have to find the 33 remaining Greater Powers themselves.Ep. 4: What are Friends For?
Ultimately, this Greater Power was never used in the show's run.
The Greater Power of Battle Fever (バトルフィーバーの大いなる力, Batoru Fībā no Ōinaru Chikara) was given to the Gokaigers on Christmas Eve by Shirou Akebono (Battle Kenya) as a Christmas Gift.
After the Gokaigers gained the Magirangers' Greater Power of MagiDragon, Luka (Gokai Yellow) tried to summon the Greater Power of Battle Fever, which, seeing as how the Magiranger's Greater Power was MagiDragon, guessed was the Battle Fever Dragon, but nothing came out of GokaiOh. The Gokaigers soon realised that they would have to find all 33 remaining Greater Powers themselves. Ep. 4: What are Friends For?
Ultimately, this Greater Power was never used in the show's run.
The Greater Power of the Denzimen (デンジマンの大いなる力, Denjiman no Ōinaru Chikara) was granted to the Gokaigers by Daigorou Oume (DenziBlue) during the return of the Black Cross King.
Ultimately, this Greater Power was never used in the show's run.
The Greater Power of the Sun Vulcan (ンバルカンの大いなる力, San Barukan no Ōinaru Chikara) was taken by Basco ta Jolokia. After the Gokaiger defeated him, it was formally issued to the space pirates by Takayuki Hiba (VulEagle).
Ultimately, this Greater Power was never used in the show's run.
The Greater Power of the Goggle V (ゴーグルファイブの大いなる力, Gōguru Faibu no Ōinaru Chikara) was granted to the Gokaigers by Kanpei Kuroda (GoggleBlack) during the return of the Black Cross King.
Ultimately, this Greater Power was never used in the show's run.
Super Dynamite (スーパーダイナマイト, Sūpā Dainamaito): The Dynaman's original group finisher. Dynaman's Greater Power was granted to the Gokaigers by Rei Tachibana (DynaPink) during the return of the Black Cross King.
The Dynaman Greater Power gave Goren GokaiOh enough explosive power to fly through a fleet of Zangyack Battleships, causing them to explode in the Gokai Super Dynamite (ゴーカイスーパーダイナマイト, Gōkai Sūpā Dainamaito) attack.
The Greater Power of the Biomen (バイオマンの大いなる力, Baioman no Ōinaru Chikara) was granted to the Gokaigers by Shirou Gou (Red One) during the return of the Black Cross King.
Ultimately, this Greater Power was never used in the show's run.
Earth Force (アースフォース, Āsufōsu): The mysterious yet very powerful energy utilized by the Changemen during their tenure as an active Sentai team. The Changeman Greater Power summons the Earth Force of all the Changemen and stores it within the Gokai Ho (similar to the formation of the Power Bazooka shell after the team unlocked all of their Earth Force) then fires out the cannonball-like mass of energy with immense force in the attack known as the Gokai Power Bazooka (ゴーカイパワーバズーカ, Gōkai Pawā Bazūka).
The Changemen's Greater Power was taken by Basco, wiping out the Earth Defense Force as a result and taking the Greater Power using his Rapparatta from a male EDF member. Obviously, this man was a Changeman, but his face wasn't shown, so his identity is unknown. He could be either Hiryuu Tsurugi (Change Dragon), Shou Hayate (Change Griffin) or Yuuma Oozora (Change Pegasus).
After the Gokaigers defeat Basco, it was formally issued by Shou. However, it still remains unknown if he was the EDF member that Basco had attacked or not.
The Greater Power of the Flashman (フラッシュマンの大いなる力, Furasshuman no Ōinaru Chikara) was taken by Basco. Where and how Basco obtained the Greater Power is unknown: due to the Flashman's biology, they can only last a limited period of time on Earth before the effects of the Anti-Flash Phenomenon kicks in. While the Flashman would have easily taken part in the Legend War without any ill effect, whether they returned to the Flash System or remained on Earth after the war is unknown.
Likewise, due to Basco's ability to traverse space with the Free Joker, he could have invaded one of the Flash planets to take the Greater Power either before coming to Earth or in the midst of his Greater Power hunt as a side quest if the Flashman were not on Earth itself after the Legend War.
After the Gokaiger defeated him, it was formally issued by Dai (Green Flash).
Ultimately, this Greater Power was never used in the show's run.
Aura Power (オーラパワー, Ōra Pawā): Aura is an energy source manipulated and controlled by the Maskman; this is similar in concept as the Changeman's Earth Force, the Dairangers' Chi and the Gekirangers' Fierce Chi. The Greater Power of the Maskman allows for Aura to surround GokaiOh's right hand, which does a front flip-flying karate chop known as the Gokai Aura Galaxy (ゴーカイオーラギャラクシー, Gōkai Ōra Gyarakushī), which is similar to Galaxy Robo's finisher, except the part to assume vehicle mode to build up speed.
The Maskman's Greater Power was taken by Basco sometime before he took the Changeman Greater Power and the failed attempt at the Ohranger Greater Power. After the Gokaiger defeated him, it was formally issued by Akira, the former Blue Mask.
Super Live Robo (スーパーライブロボ, Sūpā Raibu Robo): The combination of Live Robo and Live Boxer, as well as the first combination of two individual robots into a single powerful robot, Super Live Robo returns via the Liveman Keys by transforming GokaiOh into said Sentai Robo for the Super Big Burst finisher. The Liveman's Greater Power was granted to the Gokaigers by Jou Oohara (Yellow Lion) for Joe Gibken gaining an understanding about the importance of life.
The Greater Power of the Turborangers (ターボレンジャーの大いなる力, Tāborenjā no Ōinaru Chikara) was granted to the Gokaigers by Riki Honoo (Red Turbo) during the return of the Black Cross King.
Ultimately, this Greater Power was never used in the show's run.
The Greater Power of the Fivemen (ファイブマンの大いなる力, Faibuman no Ōinaru Chikara) was taken by Basco. After the Gokaiger defeat him, it was formally issued by Remi Hoshikawa (FiveYellow).
Ultimately, this Greater Power was never used in the show's run.
Jet Phoenix (ジェットフェニックス, Jetto Fenikkusu): The finisher of Jet Icarus while in the Icarus Haken formation. While the Gokaigers are able to use an attack that allows them to assume the form of a Jet Phoenix (ジェットフェニックス, Jetto Fenikkusu)-like firebird as their finishing move as the Jetmen, Gai Yuki (Black Condor), the one who granted the Gokaigers the Jetman's Greater Power, believes his Sentai team's true Greater Power is the will to overcome any obstacle, even death. Ep. 28: Wings are Eternal
The Gokaigers later reused this Greater Power in Goren GokaiOh against a fleet of Zangyack Battleships right after using the Dynaman Greater Power for the Gokai Jet Phoenix (ゴーカイジェットフェニックス, Gōkai Jetto Fenikkusu) ramming attack, where it turned Goren GokaiOh into a fiery bird. Ep. 50: The Day of Battle
GoZyuRex (豪獣レックス, Gōjū Rekkusu): The Zyurangers' Greater Power is part of a trio of Greater Powers granted to Gai Ikari (Gokai Silver). The Greater Power of the Zyurangers is granted to him by Burai (DragonRanger), where it is incorporated in one of GoZyuJin's alternate modes, the Guardian Beast Tyrannosaurus and Dragon Caesar-like GoZyuRex.
The Greater Power resurfaces later, as well as Ryo, and during the fight, the Gokaigers in GokaiOh accessed the power of Chi for the Gokai GoZyu Chi-Power Bomber (ゴーカイ豪獣気力ボンバー, Gōkai Gōjū Kiryoku Bonbā), where GokaiOh charges immense levels of Qi within it, then infuses the energy into GoZyuJin, then attacks (while being backed by GokaiOh) drill arm-first through the target.
Ninjaman (ニンジャマン): The pupil of the Three Shinshou, he was an ally of the Kakurangers. He was sealed within a pot as punishment in the Negakure Temple, to be released in ten years. After the Gokaigers release him, he decides to observe the Gokaigers to see if they are worthy to have the Kakurangers' Greater Power. The Gokaigers then gain Ninjaman's approval and gained the Kakurangers' Greater Power, which unknowingly was himself. Ninjaman is the final free Greater Power the Gokaigers obtained.
The Greater Power of the Ohrangers (オーレンジャーの大いなる力, Ōrenjā no Ōinaru Chikara) was supposed to be granted by Momo Maruo (OhPink) as per a plan made by the Ohrangers and U.A.O.H., but it ended up being Gorou Hoshino (OhRed) when the Gokaigers went over to face Basco Ep. 31: Crash!! Secret Operations.
It is used in the completion of the GokaiGalleon Buster, which is similar to the Olé Bazooka. The Greater Power itself is to bring the powers of a team together for a devastating attack.
The Greater Power of the Carrangers (カーレンジャーの大いなる力, Kārenjā no Ōinaru Chikara): While GokaiOh is able to perform an attack that resembles the finishing attack of RV Robo, Kyousuke states that the Carrangers' pose is the actual Greater Power of the Carrangers, leading Navi to believe that some Greater Powers are useless.
The Carranger's Greater Power was granted to the Gokaigers by Kyousuke Jinnai (Red Racer), after they manage to appeal to a crowd of children for Kyousuke's traffic safety act.
Mega Winger's Mega Wing (メガウインガーのメガウイング, Mega Uingā no Mega Uingu): The Mega Winger was the personal mecha of MegaSilver to fight alongside the other Megarangers; he usually let the Megaranger use a Mega Wing glider to become Wing Mega Voyager. Similar to this, the Greater Power of the Megarangers gives GoZyuJin Mega Winger's Mega Wing, the formation being called Wing GoZyuJin (ウイング豪獣神, Uingu Gōjūjin).
With the Megaranger Greater Power, Wing GoZyuJin can attack drill-arm first in the Gokai Spartan (ゴーカイスパルタン, Gōkai Suparutan) attack. Ep. 50: The Day of Battle
The Greater Power was granted by Kenta Date, the former MegaRed, after the Gokaigers spent a day attending Moroboshi High School, as per a deal.
The Greater Power of the Gingamen is transferred to the Black Knight Key by Hyuuga after his approval and gives it to Gai after Basco tried to actually take the Greater Power from Hyuuga.
When the Black Knight Key is inserted into GoZyuJin, it performs the GoZyu Fierce Cut (豪獣鋭断, Gōjū Eidan) attack, a spinning bifurcation attack similar to Combined Beast-Warrior BullTaurus' signature finisher.
Chemical Extinguishers: When the Gokaigers use the GoGo-V Keys, they summon five large Chemical Extinguishers from GokaiOh's hatches and the Gokai Hō. The hoses allow GokaiOh to perform the Victory Splash attack, dousing any sort of fire with five streams of highly-pressurized water. Then, this is given way for the Gokai Providence attack, where GokaiOh is surrounded by fire, much like Victory Robo, then slashes the opponent with a x-slash.
The GoGo-V's Greater Power was granted to the Gokaigers by Matsuri Tatsumi (GoPink).
GoZyuDrill (豪獣ドリル, Gōjū Doriru): The Timerangers' Greater Power is part of a trio of Greater Powers granted to Gai Ikari (Gokai Silver).
The Greater Power of the Timerangers is granted to him by Naoto Takizawa (TimeFire), where it is incorporated in one of GoZyuJin's alternate modes, GoZyuDrill, where it is summoned from the 31st century and functions much like the Timerangers' TimeJets.
GaoLion (ガオライオン, GaoRaion): GaoRed's totem Power Animal, GaoLion normally resides on the Sky Island Animarium since the defeat of the Orgs before the GokaiGalleon crew and the Zangyack arrived. He proceeds to knock them off, but his later acceptance of the Gokaigers as Super Sentai enabled him to be summoned to fight alongside them.
He can combine with GokaiOh to form Gao GokaiOh or Shinken GokaiOh, the latter the result of the Shinkenger's Greater Power. The Gokaigers gain access to GaoLion after Marvelous, Joe, and Luka saved a crowd of citizens from Action Commander Bowser and a platoon of Gormin, making them worthy in GaoLion's eyes to wield it's power.
GaoLion was later struck down by the Zangyack during The Day of Battle.
Karakuri Warrior Fuuraimaru (カラクリ武者 風雷丸, Karakuri Musha Fūraimaru) is the combination of the Fūrai Head and Fūrai Knuckle Karakuri Balls from Hurricaneger. Unlike its original form, Fūraimaru is green instead of navy blue, with elements of Tenkuujin. While the sun/moon is still on his body, it doesn't make up a majority of his body and it isn't on his chest. He combines with GokaiOh to form Hurricane GokaiOh.
The Greater Power of Hurricanegers is granted to the Gokaigers by the Hurricaneger trio of Yousuke Shiina, Nanami Nono, and Kouta Bitou (HurricaneRed, HurricaneBlue, and HurricaneYellow respectively), after their team-up battle. Before that, however, Fūraimaru appeared to help a over-powered GoZyuJin pin down Sandaaru Jr. so Gokai Silver can destroy him.
Fūraimaru was later shot off of his pinwheel/shuriken during The Day of Battle.
GoZyuJin/GoZyu GokaiOh (豪獣神/豪獣ゴーカイオー, Gōjūjin/Gōjū Gōkaiō): The Abarangers' Greater Power is part of a trio of Greater Powers granted to Gai Ikari (Gokai Silver). The Greater Power of the Abarangers is granted to him by Mikoto Nakadai (AbareKiller), who also had given Gai his Gokai Silver Ranger Key and the Gokai Cellular.
It is normally used for the GoZyuJin transformation via the AbareKiller Key, but Yukito Sanjyou (AbareBlue) teaches them that when the entire Abaranger Ranger Key Set is used, it enables the formation of GoZyu GokaiOh, where the Gokai Jet and Gokai Racer is swapped for GoZyuJin's arms.
GoZyuJin was later shot out of the sky while using the Megaranger's Greater Power in The Day of Battle.
Patstriker: The DekaMachine Patrol Striker aka Patstriker is DekaRed's personal mecha from Dekaranger. It has a different design in this season than it had in Dekaranger, with some elements from the Blast Buggy.
It combines with GokaiOh to form Deka GokaiOh. The Gokaigers gain access to it after Doggie Kruger (DekaMaster) taught Captain Marvelous the true meaning of being a Super Sentai Warrior.
MagiDragon: The MagiDragon is the first combination mecha from Magiranger, formed from the Majinn forms of the eldest four of the Ozu siblings. Unlike its original form, MagiDragon is red instead of a mix of five colors, as well as not formed from the eldest Ozu siblings. It combines with GokaiOh to form Magi GokaiOh.
The Gokaigers gain access to it after after Don used courage to save Marvelous' life, a key emotion that the Magirangers use to summon their powers, during their chase against Kai Ozu (MagiRed).
DaiBouken: The Boukengers' giant robot, the combination of the main five GoGo Vehicles, summoned by the Boukenger Keys. Using its GoGo Sword (轟轟剣, Gōgō Ken), it slashes the target twice then tosses the GoGo Sword to GokaiOh so it can pull off the Gokai Adventure Drive. The approval for the Boukenger's Greater Power in Gokaiger Goseiger Super Sentai 199 Hero Great Battle, where Satoru Akashi (Bouken Red) granted it, who also appeared to find the Heart of Hades.
GekiBeasts: When the Gokaigers use the Gekiranger Keys, they summon the GekiBeasts (GekiTiger, GekiCheetah, GekiJaguar, GekiWolf, and SaiDain). The GekiBeasts emerge from the limb hatches and the Gokai Hō to allow GokaiOh to perform a finishing attack called the Gokai Great Geki-Geki Beast (ゴーカイ大ゲキゲキ獣, Gōkai Dai Geki Geki Jū). When the Gekiranger key is used in Kaizoku Sentai Gokaiger the Movie: The Flying Ghost Ship for attack, an actual physical (not merely Geki-manifestation) GekiTiger is released alongside other Greater Powers.
The Gokaigers gain access to the GekiBeasts after Don and Ahim were taught the meaning of hard work though Juken basics by Jan Kandou (GekiRed).
Engine Machalcon: A hybrid between a falcon and a Formula-1 race car as well as the son of Speedor and Bear RV who ends his sentences with "Bari Bari!". He is summoned by the Go-Onger Keys. As an Engine, Machalcon's number is 13, with the 3 looking like three drag pipes.
The Go-Onger's Greater Power was given by Saki Rouyama (Go-On Yellow) in Gokaiger Goseiger Super Sentai 199 Hero Great Battle though the Gokaigers never discovered what it was until they encounter Sosuke Esumi (Go-On Red), who leads them to Machalcon. Later, Machalcon combined with GokaiOh to form Go-On GokaiOh.
Machalcon was later beaten and sent back into Machine World Braneworld during the events of The Day of Battle.
Mojikara: the Shinkengers' main elemental kanji-based source of power, which they had used for a lot of purposes, including fighting Ayakashi. The access to Mojikara is summoned by the Shinkenger Keys and channeled through GaoLion, allowing GaoLion to combine with GokaiOh to form Shinken GokaiOh. The merging of GaoLion in the chest of the mech is similar both to Hyakujuu Gattai GaoKing, which was how it was originally used, as well as the appearance of the lion--like Shishi Origami in the Shinkenger's Samurai Gattai ShinkenOh.
The Mojikara is accessed after the team's bonds impress Kaoru Shiba (Princess Shinken Red) and they gain her approval.
Kanzen GokaiOh (カンゼンゴーカイオー, Kanzen Gōkaiō, Complete GokaiOh) is the combination of GokaiOh, GoZyuJin, and Machalcon when the Greater Powers of the Gokaigers, the Kanzen Soul, is used and inserted into Machalcon. Kanzen GokaiOh can use the Kanzen Drill (カンゼンドリル, Kanzen Doriru) slash attack with it's right arm and the Kanzen Missiles (カンゼンミサイル, Kanzen Misairu) attacks from the left-sided fingers. Kanzen GokaiOh's finishing move is the Gokai Kanzen Burst (ゴーカイカンゼンバースト, Kanzen Gōkai Bāsuto), where the oversized left fist is fired off of Kanzen GokaiOh and strikes the opponent with enough force to go through it.
The idea of the Greater Power of the Gokaigers themselves was first pondered by Engine Machalcon, when he asked them what their own Greater Power was, since they were using Greater Powers of other Sentai teams, he being the Greater Power of the Go-Ongers. They didn't have a clue as they never thought of it before, though Luka suggested that it could simply be GokaiOh. Ep. 37: The Strongest Fighting Machine
A fun fact about this power is that with Machalcon joining Marvelous's crew, this is a combination of everyone that is a part of this crew, symbolizing the desire to seize their dreams.
This Greater Power is unique compared to that of the previous 35 Sentai in that it is not accessed by the Go-Busters' own Ranger Keys, as they are exclusive to the toyline and don't appear on-screen.
The Greater Power of the Kamen Riders will be pursued by Emperor Marvelous, leader of DaiZangyack, to claim the Ultimate Treasure in the Universe, the Kamen Rider Series' equivalent of the Greatest Treasure in the Universe. The treasure is later revealed to be the teamwork between Super Sentai and Kamen Riders, as shown by the Goseigers giving Kamen Riders Ryuki, Blade and Decade their reflection cards, Kamen Rider OOO giving the Gokaigers a set of medals that become the Kamen Rider OOO Ranger Keys, which they use with the Gokai Galleon Buster and Kamen Rider Fourze teaming up with the Tokumei Sentai Go-Busters and using the Super-1 and Super-3 switches to turn Go-BusterOh into Rocket Drill Go-BusterOh. Kamen Rider X Super Sentai: Super Hero Taisen
Notes
Kanzen GokaiOh's finisher is identical to V-Rex Robo's Rex Punch attack, down to the way the fist is drawn back.
Different Greater Powers can be used, as long as they don't combine with GokaiOh. In The Flying Ghost Ship the GokaigersRed Mecha Summon from Kaizoku Sentai Gokaiger the movie: the Flying ghost ship
Kanzen GokaiOh's Gokai Kanzen Burst can be upgraded to the Gokai Kanzen Super Burst, where the Greater Powers of the Gaorangers, Hurricanegers, Dekarangers, and Magirangers fire their weapons at the target as the Greater Power of the Gokaigers fire its rocket fist.
