Chouseishin Gransazer

Chouseishin Gransazer (超星神グランセイザー) (translated into English as Ultra Star God Gransazer or Super Star God Gransazer, also known as only Gransazer) is a Japanese drama produced by Toho Company Ltd. and Konami. The series aired on TV Tokyo from October 4, 2003, to September 25, 2004, with a total of 51 half-hour episodes. This series is the first of Toho's "Seishin (Star God)" series.

The premise of this series is similar to both the Super Sentai series and the manga/anime series Saint Seiya: there are 12 heroes, divided into four tribes, and each tribe has a giant transforming robot. The events and characters are described below, using in-universe tone.

Plot
Some 400,000,000 years after an advanced human civilization was destroyed by aliens, 12 direct descendants of the civilization's warriors (called "Sazers") have their powers awakened and form four tribes: Flame, Wind, Earth and Water. Each Sazer is based on a Zodiac sign represented in an animal totem or spirit representation. At first, they wage war on each other, but after learning the truth of their ancestry and their reason for awakening, the Gransazer tribes unite to protect Earth from the Warp Monarch, an alliance of various alien species, from once again extinguishing all life on the planet.

1st Arc: Karin Saeki and the 4 tribes (1–24)
The archaeologist Ichiro Horiguchi has indeed discovered a crystal tablet that revealed the existence of this ancient civilization and Gransazers. As luck would have it, his assistant Mika (Mithras) happened to be a Gransazer belonging to the Flames Tribe, and they soon met the second member of this Tribe, the impetuous Tenma (Tarious) and also the third one Ken (Lion), who was also Mika's younger brother. Together, they go in search of the other three Tribes and the corresponding Chouseishins.

Unfortunately for them, a scientist named Karin Saeki has meanwhile gathered the members of the Wind Tribe and convinced them that the Flames represents a threat to the Earth. Then start a race against the clock between the two camps to gather the members of the Tribe of the Earth and locate the Chouseishins, even destroying them to prevent the other camp from seizing them.

The Earth Tribe quickly ranks side by side with the Flames, while Wind's members begin to have doubts about Karin's sincerity except for their leader, Remls, who is in love with her. And the result prove them right: Karin is actually an extraterrestrial planet Akelon sent to Earth by a mysterious sponsor to destroy the Gransazers. Her true nature revealed, Karin is transformed into a giant monster that is destroyed by Chouseishins three tribes finally reconciled.

After Karin's defeat, the Impacters, a trio of extraterrestrial fighters uniting Logia, Lucia and Radia, are sent to Earth to destroy Leviathan, the Chouseishin of the Water Tribe, before the Gransazers find him. Unfortunately, all their attempts are turned against them. They first send an asteroid crashing on the island where it is hidden but Cloud Dragon (the ship carrying Chouseishins) destroys it and the debris free Leviathan from his hiding place. Radia then turns into a giant to destroy him but he is killed after the Water Tribe has appeared and taken control of Leviathan.

For his part, Horiguchi discovered the existence of a fifth Chouseishin, Guntras, and tried to repair the apparatus to control it with the help of Professor Masaki Wakui and his assistant Shûichi Hoshiyama. Unfortunately, once the device is repaired, it is stolen by Shuichi who was in fact Logia disguised, who uses it to take control of Guntras he intends to explode inside the sun to destroy our solar system. The Gransazers happily fail his project and the control system is destroyed, making Guntras autonomous.

Subsequently, the Gransazers discover that the other Chouseishins can combine with Guntras to form a giant dragon named Daisazer. Thanks to him, they manage to triumph over Lucia turned into an uncontrollable giant, then Dailogian, a giant robot driven by Logia. Vanquished, the latter commits suicide (apparently) using a device of self-destruction.

2nd Arc: Various aliens (25–41)
Unlike the other parts which are characterized by a main plot spanning several episodes and by one or more main opponents, the third prefers to focus on independent stories in one or two episodes using the classic formula of "one episode = an opponent", with the exception of episodes 33, 34, 40 and 41, in which the Gransazers are once again confronted with a living Logia and drunk with revenge.

The different episodes, however, have good suspense and carefully avoid the trap of repetitiveness. In addition, the fact that most of the episodes of this third part give the spotlight to only one Gransazer at a time makes it possible to flesh out characters that the series had difficulty to develop in the other episodes which privileged the team with the detriment of his members.

This third part also introduces a last giant robot designed by the JSDF, Yuhi, and the Gran Vehicles, individual vessels that the Gransazers fly when they do not command their Chouseishins. Unfortunately, after the rise that marked the second part, it all seems a little light.

Final Arc: Bosquito and Wolf Manafu (42–51)
The third and final part begins when an alien named Luka frees Bosquito, a particularly powerful and dangerous creature with the same powers as the Gransazers. Bosquito is finally defeated after four episodes, many civilian casualties and the sacrifice of Luka, while one of the Gransazers, Ran (Visuel), discovers a great affinity with the crystal tablet that reveals to her that the first Gransazers had been created to fight the Bosquitos who are the real ones responsible for the destruction of the ancient earth civilization, while the famous extraterrestrial fleet had actually intervened at the request of the space union Wolf Manafu to help Earth fight them after they took control of Chouseishins.

Unfortunately, convinced that the current earthlings are descendants of Bosquitos, Wolf Manafu decides to launch a new attack on our planet, which is an opportunity to discover that their ships have hardly changed in 400 million years. As the fleet gets closer, the Japanese army and the Gransazers are contacted by Brighton, a "peaceful" envoy of Wolf Manafu, who tells them that Ran is actually a Bosquito. Horrified, she is ready to let Wolf Manafu execute her, unaware that it is a trick to eliminate her because she is the only one able to use the crystal tablet to communicate with the leader of Wolf Manafu.

For the home run, writers set the bar in terms of threats, starting with Bosquito, a formidable predator whose new abilities are constantly being discovered and which will cause the death of many civilians (whereas in previous episodes the collateral victims of the battles of our heroes were generally ignored), before continuing with the threat of a fleet ready to exterminate the human race. It is also in this last part that the writers finally solve the questions asked at the beginning of the series by revealing the reasons for the battle that had opposed the Earth to Wolf Manafu while going against the expectations of the viewer, since unlike To the appearance, the squadron of Wolf Manafu did not fight Earthlings but Bosquitos.

The GranSazers
Descendants of the warriors from the ancient human civilization, they later learn that the GranSazers were created to protect Earth from the Bosquito. Each GranSazer is marked by a glowing symbol, corresponding to their astrological sign, on the back of their left hand. This symbol can turn into a Knuckle-Riser. By setting the Knuckle-Riser to "Transformation Mode", they can equip high-powered suits that transform them into GranSazers. Their transformation call is "Equip!" (装着)

GranSazer is composed by 12 members split amongst four elements. When three members of the same element have been awakened and gathered, a Tribe is formed. When three members gather and set their Knuckle-Risers to ChouSeiShin Mode, they can summon a machine of incredible power called an Ultra Star God (超星神). Once a Tribe's respective ChouSeiShin has been summoned, one member can set their Knuckle-Riser to "Boarding Mode" to "Dive-In" and board their ChouSeiShin. The one who is on their ChouSeiShin can change into a giant folding robot. The other two GranSazers would later pilot jetfighters called Gran Vehicles.

Each GranSazer also has their own unique weapon, which can be summoned by setting their Knuckle-Riser to "Arms Mode". When piloting their respective ChouSeiShin, they can equip the ChouSeiShin with a large version of their personal weapon by setting their Knuckle-Riser to "Sazer-Gear Mode". They can also communicate with other Sazers by setting the Knuckle-Riser to "Communication Mode".

The GranSazers can also perform a combination attack called "Formation Zero". The attack involves Sazer-Tarious, Sazer-Mithras, Sazer-Lion, Sazer-Dail, Sazer-Tragos and Sazer-Pisces all performing a sandwich jump kick on the enemy.

Flame Tribe
The Flame Tribe or Fire Tribe (炎のトライブ) are the first tribe to recognize the alien threat and the second to be fully assembled. From the very beginning, they were assisted by Professor Horiguchi, who helped them realize their duty as Gransazers. The Flame Tribe armoured suits are all bird-shaped with red-based colour and they pilot the Flame-Driver Grand Vehicles. This tribe is also the one and only tribe which two of their members (Tarious and Lion) can equip Garuda with a large version of their personal weapon by setting their Knuckle-Riser to "Sazer Gear Mode" rather than other tribes which only their leader (Remls, Tawlon and Gorbion) can use this mode on their ChouSeiShin.

Sazer Tarious
Tenma Kudou (弓道 天馬), born on December 14, 1983, is a rash postman, usually going in head first. He stumbled into being a Sazer after he was harassed by Sazer-Velsou; his temper and the powers within him made him transform. Immediately afterwards, he defeated Velsou. Often locking horns with Mika and the others, he doesn't quite like being made the leader, but he accepts the role. Tenma cares a lot about his comrades as well as about the world he lives.

However, he survived his suicide and resurfaces upon regaining Dailogian and his Hiro-Sniper from the JDSF's Scientific Research Lab, beginning his vendetta against the Gransazers by kidnapping Ryouko and Ran and capturing Tappei, leaving them at the mercy of a time-bomb while he goes after Tarius to personally kill him. But when the plan goes array, Logia summons DaiLogian to crush Tarius as the Yuuhi arrives to hold him at bay under reinforcements arrive in the GranVehicles and drive him off. Logia later resumes his attack at the JD Weapon Institute to get Okito and Yuuhi under his control to hold Daisazer while weakened. But the plan fails and Logia goes to hell again after Dailogian is damaged by Daisazer, found by Belzeus who offers him another chance by increasing his power and reviving Logia in return for the Crystal Slab by taking Mika and Professor Horiguchi as hostages to force Tenma to hand deliver it to him alone.

Once he smashes the Crystal Slab, unaware that it's a fake, Logia fight Tenma to his heart's content until the other Gransazers arrive to free Mika as the Professor Horiguchi as they even the odds and force Logia to use DaiLogian to fight Daisazer until Belzeus is tired of Logia's arrogance, forcing him out of DaiLogian as it leaves under Belzeus control. Refusing to give up, Logia abducts Mika who tends to his wounds before he lets her go as he goes to hunt down the Belzeus-controlled DaiLogian and reclaim it as he and Tarious settle things in a one-on-one fist fight. But the fight ends in a draw as a satisfied Logia leaves, later returning to aid them in fighting Belzeus, though he still sees Tenma as an eternal rival.

After getting scarred by Ai, Lucia attempts to get revenge on her, both Ran and Mika arrive to Ai's aid and defeat Lucia, mortally wounding her and taking her to the hospital in hopes of healing her.

After being healed, Lucia learns that she is no longer to continue the mission. However, going against the order, she use Accelerator to increase her power, turning into a giant version of herself in spite that that Accelerator's long-term effect would make her into a mindless monster and eventually kill her. Though she over-powered the Chouseishin with her cloaking and clone abilities before enlarging herself even more, Lucia is outmatched by Daisazer with its pilots stopping it in time before it kills her. However, Lucia succumbs to the Accelerator's effect as dies, leaving behind her card for Logia to find.

In his silver-armored fighting form, Radia uses the enormous Mega Axe in his armor.

In truth he wanted to take over Earth to gain a vital place in conquering the universe. To that end, he creates supports to his claim by having using Logia to destroy Crystal Slab to hide the truth and Luka to resurrect the last Bosquito to give Warp Monarch to attack Earth in full fury.

Brighton
A Garban Emissary sent to Earth during a 3-day ceasefire, Brighton (ブライトン) (46-48) fakes sympathy for Earth's safety by asking the JSDF to let him investigate the Gransazers, finding Ran as Communicator and claiming her to have Bosquito DNA so that he would give them reason to let him take her, thus leaving Earth with a Communicator to contact Warp Monarch. When ordered by Belzeus to kill Ran before her power can awaken, Brighton summons Algol to carry out the task. But when Algol fails, Brighton reveals his true colors as Troius sneak attacks the city. Later, while the others destroy Algol, Tarious goes after Brighton as the Garban pretends to beg for his life so he can kill Tarious with his guard down, only to be shot by Logia.

However, Logia turns the tables as he and Tarius double-team Gorgion and the Impactor about to kill him when Tarious' intervened, allowing Gorgion to escape.

 * Fedora (フェドラ) (32): The ghost of an alien soldier who died during Warp Monarch's war against Earth. Filled with undying rage towards humans and unaware that he died, Fedora possessed the body of Henry Wakasugi to continue the orders he received ages ago. It was once his identity is revealed, Tarious uses the crystal slab to make Fedora realized that he's dead, leaving Henry's body to finally rest.
 * Gadaruian (ガダル星人) (35): An alien from planet Gadaru armed with the Dead Spear, he was a scientist sent by Warp Monarch to convert humans into mindless slaves, using Ran's friends as test specimens in his research. But Ran's friends are freed from the Gadaruian's control as Tarious battles the alien and kills him with Visuel's aid.
 * Kriminel (クリミナル) (36): An alien felon with no relation to Warp Monarch, he escaped to Earth to feed on the energy there. Armed with a pistol he stole from Freedo's partner, Kriminel can absorb any heat-based energy source to heal himself and increase his power, firing stored energy from the orbs on his chest. After losing to Dail, Kriminel attracts the Fire Tribe's attention as Tenma and Mika fight him and worsen the matter. But once Dail breaks Kriminel's barrier, Freedo delivers the death-shot.
 * Gorfinian (ゴルフィン星人) (37): A Warp Monarch agent from planet Gorfin, he enters the body of Mick the dolphin at the Sea Paradise aquarium to influence the other dolphins with his hyper frequency to attack humans with sound waves. But thanks to Mayu, Mick exorcises the Gorfinian as Gans fights before Tarious and Gorbion arrive and the dolphins use their own hyper frequency to weaken the alien as Gans finishes him off.
 * Troius (トロイアス) (47-48): A giant alien monster sent from the Fleet to attack the Earth once the ceasefire ended. Dolcruz and Leviathan battle the beast with aid of the GranVehicles and Yuuhi. But the fight ends with Dolcruz heavily damaged, Yuuhi dismantled, and Tappei wounded. After Garuda got damaged as well, Guntras and Cloud Dragon intervene and destroy Troius.
 * Cabyron (キャブレオン) (50-51): Arriving in a fireball, Cabryon is used by Gorgion to attack the JSDF to draw the Gransazers out into the open to complete his mission. Carbion succeeds in damaging Guntras to keep the Gransazers from forming DaiSazer and wrecks the other Chouseishin while appearing to kill Tenma. But once Warp Monarch acknowledges the truth about Earth, the Chouseishin are restored and form DaiSazer to kill Cabyron.

Bosquito
The Bosquito (ボスキート) (42-45) is an alien construct that absorbs any lifeform in its grasp, for nourishment, into order to reproduce asexually, and able to assimilate the energy of its clone spawn when they die. It is feared across the universe, as Warp Monarch couldn't control the Bosqutio when it came to Earth, resulting in the birth of the Gransazers to counter it and the War that destroyed ancient human civilization along with the propaganda set up to link the Bosquito to Earth's people. Though nearly wiped out, the Bosquito was sealed away, within the Kabuto Mountain, until Luka revived it on Belzeus' order, with no idea who she was reviving, until it was too late. Being able to use any attack used by the Gransazers, the Bosquito overpowers the Flame Tribe and later attacks a village, feeding on the people there, before using the TV to find ideal locations to feed on next. After evading the Wind Tribe, the Bosquito reproduces a child before fighting the Gransazers and is killed by them. The surviving child began to feed when Makoto and Jin arrive and were attacked as Tauron arrives to support them before the Bosquito multiplies itself as the Flame Tribe arrive to counter the second Bosquito until Yuuhi blasts it. Absorbing its clone, the Bosquito takes the controls for Yuuhi and uses it against the Gransazers, stealing Garuda when the Flame Tribe summons it. Levithan and Gunceasar are summoned to weaken Garuda so eject the Bosquito, who starts to absorb the floral life energy to regain its strength and create two clones of itself. After the others destroy the clones, the orbs they left behind are reabsorbed into the original Bosquito as it evolves into a giant monster. After Tarius uses one of Lion's Crescents to take the ruby on its chest, the source of its power, the Bosquito is destroyed by DaiSazer.

However, as revealed in the Seishin crossover (Chousei Kantai Sazer-X: The Movie), another Bosquito existed within the monster Bulgario, released when the monster was destroyed at sea, absorbing the JustiPower in Sazer Island, so it can duplicate itself and can disguise themselves as impostor Justirisers. They are all destroyed by Gransazers, Justirisers and Sazer-X but quickly absorbed into the phantom ship so that it would form into Mammoth-Bosquito dragon. The Mammoth-Bosquito is destroyed by Great-Lio (piloted by Lio-Sazer) using the final move, Howling Crush, which the power of Gransazers, Justirisers and Sazer-X combined into the finishing attack to destroy the monster.

ChouSeiShin
The ChouSeiShin (Ultra Star Gods or Super Star Gods) are the most powerful weapons of the ancient Earth Civilization. They remained dormant on Earth until the GranSazers were awakened, and reactivated the long-lost relics.

Each Tribe possesses one of the four ChouSeiShin, which can be summoned by setting all of their Knuckle-Risers to "ChouSeiShin Mode". One member of the Tribe can then "Dive In" and board the machine by setting their Knuckle-Riser to "Boarding Mode". Furthermore, by setting their Knuckle-Riser to "Sazer Gear Mode" the pilot can equip their ChouSeiShin with a large version of their personal weapon.

Each ChouSeiShin has two modes, which can be switched between with a simple transformation. In "Live Mode", they resemble animals and possess incredible maneuverability. In Warrior Mode, they resemble bipedal mecha, losing most of their speed, but gaining immense attacking power.

ChouSeiShin Garuda
ChouSeiShin Garuda (超星神ガルーダ) is the Flame Tribe's ChouSeiShin, the second to be awaken from its slumber in Hōō Mountain. In Live Mode, Garuda is shaped after a phoenix and attacks with his guns located under its wings where its legs are, firing lasers and energy beams. Garuda can also tackle enemies after engulfing himself in flames. In Warrior Mode, Garuda mostly relies on the 'Garu Claw', which are his talons on the back of his fists, for close-range combat. He performs his finishing move "Fire Bird Slash" with them. Garuda can also summon a sword called Burning Saber for armed melee combat. Tarious' Sazer Gear equips Garuda with a giant version of the Falcon Bow, and Lion's Sazer Gear equips Garuda with giant versions of the Double Crescents.

ChouSeiShin Dorcrus
ChouSeiShin Dorcrus (超星神ドルクルス) also known as Dorcrus or Dorcrus is the Wind Tribe's ChouSeiShin, the first to be awakened from its slumber in Kabuto Mountain. In Live Mode, Dorcrus is shaped after a European rhinoceros beetle and attacks with his multitude of cannons as well as with full tackles. In Warrior Mode, Dorcrus uses his large array of cannons and blasters to perform various attacks. His finishing move, "Herakles Hurricane", fires his entire arsenal of cannons and blasters simultaneously. Remls' Sazer Gear equips Dorcrus with a giant version of the Iron Gale on his head, since Dolcruz does not have proper hands to hold objects (in theory).

ChouSeiShin GunCaesar
ChouSeiShin GunCaesar (超星神ガンシーサー) is the Earth Tribe's ChouSeiShin, the third to be awaken from its slumber in the Shishioh Desert. In Live Mode, GunCaesar is shaped after a liger and attacks with his cannons as well as with his claws. In Warrior Mode, GunCaesar uses his cannons, the Liger Riots, as hand blasters. He performs his finishing move, "Gravity Burst", with them. Tawlon's Sazer Gear equips GunCaesar with a giant version of the Bull Cannon.

ChouSeiShin Leviathan
ChouSeiShin Leviathan (超星神リヴァイアサン) Whale is the Water Tribe's ChouSeiShin, the last to be awaken from its slumber in Shinkujira Island Water when the Impactors arrive on Earth. In Live Mode, Leviathan has a whale-like shape and uses his fins for ramming attacks, as well as firing his two cannons at the fins. In Warrior Mode, Leviathan is armed with the Maelstrom Blades which can be used for his finishing move "High Tide Break". Furthermore, he is equipped with the Ocean Shield which can be used for his another move "Mirage Shield" which can multiply for defence purposes. Gorbion's Sazer Gear equips Leviathan with a giant version of the Blast Saw.

ChouSeiShin Guntras
ChouSeiShin Guntras (超星神ガントラス) is controlled by an advanced AI, superior to the other ChouSeiShin to have a will of his own. Initially hidden away in the Andes, referred as the "Great Shadow" in Peruvian legend, Guntras resurfaced when his Guntroller is repaired and Logia controls him, planning to use Guntras' oxygen fuel supply to collide with the Sun and trigger a nova strong enough to evaporate Earth, after killing the GranSazers first. Tenma eventually got the Guntroller and freed Guntras, who joined up with Cloud Dragon as an ally to the Sazers. Later Guntras is revealed to be created to combine the four ChouSeiShin into one giant super robot (DaiSazer). Guntras is armed with an array of deadly weapons, among them a laser battery on his chest, a cannon on his forehead and missile launchers on his body. He can fire and immediately replace his fists in his Twin Crusher attack, and his powerful feet can create devastating shockwaves in his Land Shake attack.

Fusion Beast-King DaiSazer
Fusion Beast-King DaiSazer (合神獣王ダイセイザー) Dragon/Megalosaurus is the assembled form of the four Tribes' ChouSeishin, along with ChouSeishin Guntras. Guntras forms the main body, head and feet; Garuda for chest, cranium, and back; Dorcrus for the legs; GunCaesar for the right arm and the shoulder cannons; and Leviathan for the left arm and the tail. Combined, DaiSazer has a very aggressive and archaic mind of its own. All four pilots have to focus to control DaiSazer. DaiSazer is a very deadly creature and it is armed with a deflector as well as a laser array on its chest, but DaiSazer mostly relies on brute force to deal with its opponents.

Its attacks include: 'Rapid Sazer', which fires the shoulder cannons on its back; 'Blast Pressure', unleashing a blast of fire from Guncaesar's mouth on its right arm; 'God Sphere', firing energy beams from its eyes. Its finishing move is 'Hyper Burst', which unleashes the full power of Guntras and the 4 ChouSeiShin combined through the laser array on its chest.

ChouSeiJuuren Cloud Dragon
ChouSeiJuuren Cloud Dragon (超星獣連クラウドドラゴン), translated into English as Ultra Star Beast Carrier Cloud Dragon, is as old as the ChouSeiShin, another remnant of the ancient civilization and residing within the ozone layer of the Earth to protect it from alien invaders, implanted with a DNA of humanity to start back up the human race and an AI modeled after a woman from ancient civilization. She only descends from the ozone layer if the ChouSeiShin are summoned or are in need of her help for repairs. The Cloud Dragon is designed for combat support and repairs the ChouSeishin after they suffered battle damage and rendered immobile as a result, in which a sky whirlpool is created to collect the damaged ChouSeiShin and loads them onto one of the 4 storage pads (for the ChouSeiShin of each Tribe in the order of Flame (Garuda), Wind (Dorcrus), Earth (GunCaesar) and Water (Leviathan) respectively) on its body for repairs and restoration in outer space (the first such repairs is done onto the Flame ChouSeiShin Garuda by restoring its damaged left wing), upon which they can be launched straight from the colossal Dragon's storage pads once fully repaired and when the Gransazers summon them. Prior to the final battle, Cloud Dragon formally introduces herself to the GranSazers before telling them they have the answer to stop the attack on Earth. The Cloud Dragon's attack is the Galactica Prominence Cannon, a devastating blaster capable of blowing an entire asteroid into pieces. Inside cloud dragon there are GranVehicle which is one for each tribe's member. GranVehicle of flame tribe is flame driver, wind tribe's vehicle is wind driver, earth tribe's is earth driver, and the water tribe's is aqua driver, which is one for each gransazer. With gransazers knuckle riser there is GranVehicle mode. The Sazers who dives in they on's their GranVehicle mode and says GranVehicle launch and dives in. on the cloud dragon the place where these GranVehicles launch is where Guntras stands in front is place where GranVehicles launch which is one for everyone. Cloud Dragon's Zodiac sign is unofficial 13th sign, Ophiuchus.

DaiLogian
Dailogian is Logia's personal mecha. It is a black humanoid robot patterned after a wolf and its power is almost equal to Daisazer's. Unlike his subordinates, Lucia and Radia, Logia cannot grow into a giant; instead, he summons his mecha, which is always on standby in outer space, and which Logia alone can summon. It can absorb beam attacks through its chest and redirect them back to the opponents. It first fought with Daisazer and was defeated when Daisazer ripped off its arm. The second time was when Logia and Tenma fought one on one in their respective mechas with Tenma barely securing the victory. After DaiLogian was defeated, it was taken by the Japan Self-Defense Force for study. It reactivated, then busted out of the Japan Self-Defense Force holding area, when Logia returned to Earth to seek vengeance against the Sazers. Afterwards, Logia used it as a mode of transport.

Yuuhi
The Type-05 GS Assist Robot Yuuhi (五式支援機士ユウヒ) (28-48)was the result of the JSDF reverse engineering DaiLogian so they can support the Gransazers' Chouseishin. Remote controlled by a voice-command headgear, the Yuuhi is launched from an underground bunker. It can access numerous weapons, a 120-mm dual cannon as well as two arrays of six missile launchers each. Prior to the final battle, Yuuhi was broken into pieces after fighting Troius.

Type-05 GS Assist Tank "Asahi"
Asahi is Yuuhi's support mecha. It vaguely resembles an M4 Sherman.
