A summary of the Battle Story from multiple sources.


  • All dates are ZAC ("7 or 8 periods ahead of Earth's calendar" according to History of Zoids).
  • Information about ZAC 2030-2056 originating from Shogakukan's School Grade magazines is in bold, as it often conflicts with early Tomy info (boxes, Graphics, History of Zoids) and All About Battle Machine Beasts (also by Shogakukan) - these sources are in italics.
  • The "new Zoids" column shows important examples, not every Zoid released at that time.

The Republic recaptures their capital city, and later airdrops the advanced prosthetics into towns full of injured Zenebas soldiers. Lidier B4
3/2051 Having recaptured the Republic capital, the Madthunder invades deep into Empire territory. Cornered on Nicaidos Island but unwilling to hand the continent over to Helic, Zenebas sends a messenger to the Dark Continent... The Republic sends in over 200 "Big Mothers", Madthunders under an Ultrasaurus shell. Zenebas escapes in a small scout vehicle.
That evening, the Dark Army arrives with incredibly powerful Zoids like the Deadborder. The Republic retreats, but the Dark Army attacks the Zenebas Empire first, defeating Zenebas' personal Zoid and seemingly killing him. They capture Zenebas' daughter Elena and his adopted son Störmer (Gambino's son), with their leader (Evil Emperor Guylos) using Elena as a hostage, and absorb the Zenebas Zoids and soldiers into their own army before retreating as quickly as they appeared. The Republic manages to shoot down one of the escaping Whale Kaisers.

11/2052 A scout Puterasu discovers a secret Dark Army base in the mountains, 800 km from Entrance Bay, so the Republic sends in a remote-controlled Madthunder as a Trojan horse and throws the base into chaos. However, a Black Kong shows up and fires a mysterious halo that slices a Shieldliger in half - lengthways. But the shield of Lieutenant Krüger's Gunbluster manages to withstand the new weapon and he shoots down the Kong. Houndsoldier

However, the Gil Vader survives and attacks the nearby Madthunder awaiting the return of the Kingligers. Krüger uses his Salamander F2 as a shield, but the dying F2 saves his life by force-ejecting him. B5
10/5/2054 The 35 Madthunders remaining on the Central Continent are converted into sea battle types and set out on the Navy Memorial Day to defeat the Gil Vader. Because of the mission's importance, they use the HZ code, which "only Helic and Zenebas knew"... but the fleet is ambushed and wiped out by sea and air Gil Vaders. Helic realises that Zenebas must still be alive, but a prisoner of the Dark Army. B5


Guylos sends 10 Gil Vaders to attack the Central Continent, and Helic uses his last option: sending Krüger in the prototype Orudios (developed by Graham) to defeat a Gil Vader. Krüger stabs the Gil Vader's cockpit with the horn of the Orudios, killing its pilot, then self-destructs the damaged Orudios to keep it a secret and walks off into the desert, where he finds the Raynos that he abandoned in the failed landing 3 years ago. Meanwhile, Helic sends a fake transmission using the HZ code, claiming that 500 Orudios have been deployed, so the Gil Vader battalion retreats and the Republic is safe once more. Orudios B5, R

11/2056 Using all their technology, the Republic creates the King Gojulas, an ultra-powerful Zoid that annihilates the Dark Army and their castle. The Descat sets out to stop it, but before they can battle, one of Zi's moons is hit by the comet Thorne and shatters, raining meteors down on Zi. The Central Continent is split into 3 segments, part of the Dark Continent sinks, and magnetic storms prevent all combat Zoids from moving, finally putting an end to the war... perhaps. Helic, the pilot of the King Gojulas, abandons the damaged Zoid and returns home with Elena, who he finds during his escape. King Gojulas
G21, M, R
2057 Both countries begin to rebuild, but both are secretly working on Zoids that can fight among the magnetic storms. During the funeral of Emperor Zenebas, who died during the Grand Catastrophe, scientist Kenneth Oldvine asks soldiers Rowan Zaguli and Faust Ramberg to dig up the wreckage of the King Gojulas so that its gravity supertechnology can be put to use. Later, Helic and Elena travel to the neutral Western Continent for a peace talk, but are instead ambushed by the Empire army and Ramberg's new Valga, which uses gravity technology from the King Gojulas as a weapon. The Republic defence force, led by Will Craig in a Dos Godos, holds them off while Helic and Elena escape. Dos Godos
10/2058 In an attempt to erase the gravity supertechnology, Helic launches Operation Iron Hand and sends an invasion force to the Empire facility of Levante Island. They are met with strong resistance from sea and land, but manage to land successfully. Zaguli attacks in his new Crimson Horn, guarded by unmanned Zeek Dobers, but he is pinned down by the Republic's smaller Zoids while Craig's Dos Godos force proceeds into the research facility. After fighting their way to the centre, they learn that Republic scientist Ril Meryl was a spy and that the entire island is a trap that will collapse if they destroy the facility.

Realising that the Zoid could be a threat to the entire planet, they work together to kill it, with Arthur sacrificing himself to save Ritz.
The Republic continues to advance, cornering the Empire army at Nixie Base. Ex-Zenebas soldiers are sent out in Elephanders to sacrifice themselves and buy time for the rest of the army to withdraw. An elite Republic team invades the base and finds the Interface that the Empire has been excavating, along with two prototype Zoids.

8/2101 When the Ray Force penetrates deep into Empire territory, the Eisen Dragoon reveals their plan: to weaken both sides equally until they can take over. The Ray Force's Zoids are frozen by the Grounchar's jamming waves, but they are saved by the shields and firepower of reactivated Gunblusters. Ray has almost defeated Wolff when the Bloody Demon, an experimental Death Saurer variant, appears and wipes out the force. Ray uses a mix of all the CAS equipment left in the burning Hover Cargo to defeat the Bloody Demon, but Wolff recovers its pilot and escapes to rejoin the Eisen Dragoon's main force. F3, M
~9/2101 A Republic scout team infiltrates an Empire base and discovers their new Liger Zero variant, finding that the König Wolf is no match for the Zero X. Soon after, the Republic sends their recreated Madthunder on a secret mission, but are attacked by a Guylos force. Prozen then airdrops a prototype Dark Spiner into the battle, intending to remote-destruct it and take out both sides, but the two teams work together to defeat the Dark Spiner and are narrowly saved from the explosion by the Madthunder's Anti-Charged Particle Shield.

9/2101 High-ranking soldiers Herman and Schubaltz hold a secret meeting to discuss the Eisen Dragoon's plot, but Prozen sends a Liger Zero X to assassinate them. Schubaltz (and Tommy Paris) are seriously wounded, but Hermann uses a König Wolf DSR to snipe the Zero X's pilot while it is distracted trying to take out a Republic Madthunder being repaired in the nearby factory. However, the Empire has finally managed to resurrect their Death Saurer cores (again thanks to the Organoid System), and Prozen sends fifty Death Saurers in an all-out assault on the Republic, keeping his Prozen Knights in reserve.
Meanwhile, on the Western Continent, a Molga force delivering a new Chimera Core meets the prototype Gojulasgiga, but Jasz Noguchi's Molga Rokurou Special manages to knock it off a cliff and destroy it.

11/2101 Prozen finally unveils his plot, using the Prozen Knights to take over the Empire capital Valhalla and kidnap Emperor Rudolph. He explains to Rudolph that he is the son of Zenebas Muroa and intends to revive the Zenebas Empire. In order to annihilate both armies, he has hidden countless Zoid Cores underneath the city, rigged to self-destruct at his command. While the combined Helic/Guylos army invades the capital and takes down the Prozen Knights, Rudolph challenges Prozen to a Zoid battle, managing to disconnect some of the tubes connecting the Zoid Cores to Prozen's Bloody Death Saurer. Prozen tries to force Rudolph's gold Saber Tiger to press the detonation switch, but Schubaltz's Iron Kong bursts in, shooting the Death Saurer's cockpit and shielding Rudolph. Fatally wounded, Prozen sets his Zoid to overload, detonating the Zoid Cores and wiping out most of the city and both armies. Meanwhile, the Eisen Dragoon invades the virtually undefended Central Continent, using the jamming waves of the Dark Spiner to freeze the Republic's defence force. Led by Wolff Muroa, they control a quarter of the continent within three weeks, taking in citizens and forming the Neo Zenebas Empire. Snipe Master

winter 2101 A Republic scout force finds a girl living in the Central Mountain Range who possesses the Mask of Zenebas. It is the proof of inheritance of the Zenebas throne, thought to have been lost 50 years ago. However, the girl turns out to be the son of a Zenebas bodyguard, rather than a descendant of Zenebas and heir to the Neo Zenebas Empire. W, M
1/2102 The surviving remnants of the Republic army return to the Central Continent, hiding in the Central Mountain Range and working on a new Zoid whose blueprints were left behind in the Saberlion.

2104 The Republic develops a handful of Zoids using the new Blox System, which allows Zoids to combine or exchange parts. Soon after, the Neo Zenebas Empire creates the completely autonomous Chimera BLOX. However, the fighting instincts of the Chimeras soon override their programming, causing them to attack indiscriminately, and they can evolve themselves by taking in the cores and equipment of enemies. Leoblaze
autumn 2105 The Black Dragoon, led by ace pilot Genius Deldaros in a Stealth Stinger, launches an assault on a secret Republic base in the mountains. Frozen by Dark Spiners, none of the Republic Zoids can fight back except for a single Gojulas The Ogre. They consider self-destructing the almost-finished Gojulasgiga, as its anti-jamming armour is still incomplete, but the Ogre manages to defeat all the Dark Spiners and the Gojulasgiga wipes out the Black Dragoon. Elsewhere, the Diablotiger arrives from the future to battle the ancient Cyclops and a Republic pilot uses a custom Salamander to oppose the Lord Gale. Gojulasgiga

spring 2106 The Republic army begins its counterattack, invading Cook Fortress while the Empire is distracted by empty Guylos carriers arriving. Protected from jamming by the Gorhecks and surrounded by a guard unit of Arosaurers, the Gojulasgiga easily defeats the Empire forces, even a Death Saurer, and captures the fortress. Meanwhile, the Empire introduces manned BLOX Zoids such as the Lord Gale and Deantler to control the smaller Chimera BLOX. The Republic uses Rob Herman's disappearance during an anti-jamming armour test as an excuse to create a "memorial force" containing the Heavy Arms König Wolf. Deantler X4, X5, M
summer 2106 The Neo Zenebas Empire completes the Seismosaurus, whose Super-Focused Charged Particle Cannon (nicknamed the Zenebas Cannon) can destroy the Gojulasgiga from a great distance.

2107 The Republic army returns to the Central Continent with a new Zoid army created by ZOITEC. A group of Ligerzero Phoenix invades the heavily-guarded Chimaera Fortress City, defeating the army of Chimera BLOX inside. When a Seismosaurus appears, they sacrifice themselves to protect the Republic's trump card: the Gairyuki, based on a Tyrannosaurus-type wild Zoid offered by the Guylos Empire.

spring 2109 The Helic Republic sends their entire remaining army into a final battle with the Neo Zenebas Empire to regain Helic City. Emperor Wolff Muroa is ambushed by the Ray Force, but his custom Energy Liger easily defeats Ray Gregg's Zero Phoenix. Ray is saved by the arrival of the Jet Falcon, a Zoid developed for the Empire by ZOITEC but later offered to the Republic instead. The Zero Falcon stabs the Energy Liger's core, but its Energy Charger continues to produce power with nowhere for it to go, threatening to explode and wipe out both armies just like Prozen's Death Saurer. However, Wolff and Ray work together to divert the energy into the Zero Falcon, saving the two armies and providing hope that the war might finally come to an end. Jet Falcon X12

Date Events New Zoids Source
5/2230 In Blue City on the Eastern Continent, Zoids are used only for constructive purposes and entertainment, and tournament pilots called Zi-Fighters are constantly searching for the strongest Zoids. ZOITEC manages to obtain the cores of three legendary tiger-type Zoids, but when they try to construct the first one, they are forced to divide it into two Zoids (capable of combining) to keep it from overloading.

8/2230 Zi-Arms has also created the Mega Death Saurer, planning to equip it with the three tiger cores and make it the strongest Zoid in history. However, the Mega Death Saurer runs wild, and the three tigers are forced to join forces in order to defeat it. X16, D
the far future In the Beith Republic, Zoids are used for constructive purposes as well as in illegal tournaments. Despite using only Blox Zoids, the Republic plans to outlaw the Changemize technology that allows them to combine. However, the Dynas Empire discovers the Changemize technology and sends their new Groundrago to attack the Republic capital. Unable to fight it alone, the Republic's Zoids fuse into the Bitegriffon, but the Groundrago separates, cornering it. When the Empire learns of "the arrival of an unexpected enemy", the Groundrago withdraws to their mobile fortress. Both sides begin excavating the cores of "legendary" ancient Zoids and placing them into Neo Blox bodies, allowing them to form even stronger fusions such as the Valkyrie Caesar, which was sent on a mission to recover the Republic capital...
