A summary of the Battle Story universe, based on various sources. The original version was posted to the Zoids Wiki in 2011. May contain minor inaccuracies.

Notes:
 - All dates are in Planet Zi's calendar, "ZAC". (According to History of Zoids, ZAC 2029 corresponds to 2021 by "Earth's calendar", but this is likely no longer canon.)
 - Information about ZAC 2030-2056 originating from Shogakukan's Battle Story books 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 only shows important examples, not every Zoid released at that time.

Date	Events	New Zoids	Source
2030	While Zenebas is distracted by false intel, the Republic army, led by the upgraded Zoid Gojulas, makes its way to the Empire capital (a mountain castle). However, the Imperial forces return just in time to save the capital. Deep inside Zenebas territory, a Zoid Gojulas defeats a Redhorn. The Empire creates various Redhorn customs, including Bulstein, Burners and Destroller, to buy time until they can develop a more powerful Zoid.	Zoid Gojulas Redhorn	H, B1
2031	The Republic and Empire modernise their smaller Zoids and release several new models. A fleet of Furolesios and Barigators is attacked by Sinkers in Florecio Ocean, opening the doors to sea and air battles.	Sinker Barigator Salamander	B1
10/2032	A large Imperial invasion force is ambushed in the Forest of Ardannes, beginning the Battle of Ardannes, the first major fight with modernised Zoids. The eventual arrival of a Gojulas force leads to the Republic's victory.		A, Z
2032	Disappointed that Emperor Zenebas is neglecting his citizens, some of his soldiers rebel and take control of his residence. Zenebas orders their superior, Gambino, to "deal with them", but Gambino instead shows them an escape route and commits suicide afterwards. The Empire completes the Ironkong and sends 150 to invade deep into Republic territory. The Republic gathers all 200 of their functional Zoids Gojulas and repels them, but suffers heavy losses in the process.	Ironkong	H, B1
2033	Unfazed by the recent events, Zenebas starts to build up a huge army of Redhorns. Helic declares "X-Day" national emergency laws. In order to combat the Ironkong, nine Republic facilities each create a custom Gojulas design, one of which becomes the prototype for the Zoid Gojulas Mk-II.		H, A, B1
2034	Spurred on by the release of the Ironkong, both sides begin to develop many new Zoids such as the Helcat and Snakes, rapidly outclassing enemy models - sometimes within just months of their release.	Iguan Hammerrock Gustav	B1
2035	The Battle of Blood Rock begins at the mountain White Rock. The Republic receives news of a new large-scale Imperial Zoid being developed, and sends a single Gojulas to investigate. It infiltrates the Imperial factory, photographs the new Zoid, and escapes through the ceiling to be retrieved by transport Salamanders.		H, G5, G9, B1
2036	The Empire releases their new Zoid - Sabretiger, which is fast enough to defeat the Republic's biggest Zoids. Their only way to stop it is to attack from the air.	Sabretiger	B1
6/2036	The violent operation "June of Blood" commences at Blood Rock. Major General Isaac loses his son Kendall in the fighting.		H
~2036 to 2038	A large force of Sinkers attempts to attack the Republic capital via Helic Bay, but is narrowly repelled by Alpha and the coast guard. The Republic unveils the Salamander during the Battle of Blood Rock, putting the Empire in a panic. They send 3 prototype Saicurtis on a test mission to destroy a Salamander, but the mission results are unknown.	Salamander Saicurtis	H, A, G7
2037	An Imperial spy commando called "Echo" captures the Republic's prototype Ultrasaurus and tries to attack the Republic capital Helic City, but Captain R.S. Toamath snipes its cockpit with a Cannontortoise and Echo ejects. The Empire creates the Yeti Kong and Space Kong to oppose the Ultrasaurus, and their test data is used to create the Ironkong Mk-II. Echo uses a fake SOS signal to lure the Ultrasaurus into an ambush in the far north, but Toamath's Gojulas Mk-II narrowly defeats his Ironkong Mk-II, killing him.	Ultrasaurus Ironkong Mk-II Gojulas Mk-II	B1
~2038	The first Ultrasaurus is released and penetrates deep into Empire territory, only stopped by a huge battalion. Zenebas declares X-Day, but once the Ultrasaurus is mass-produced, the Empire capital falls.	Ironkong Ultrasaurus	G8, G9, K
2038	The Empire launches a large-scale invasion of the Republic, starting by besieging a radio base on the border. The Republic soldiers flee into Imperial territory in an Ultrasaurus, but are soon surrounded. However, the Ultrasaurus uses a special omni-directional attack to wipe out the Imperial Zoids and escape. Five elite Imperial divisions fight their way across Republic territory, but the Republic manages to hold them off until the rainy season, then secretly launches an invasion of their own. An Ultrasaurus force lands at Mivalos Bay and fights its way north to bombard the Imperial headquarters. Having cut the Empire's supply lines and destroyed their headquarters, the Republic quickly gains the upper hand and progresses steadily towards the Imperial capital.		B1
9/2038	The Republic receives news of a huge new Imperial Zoid, and both countries send their entire armies to Blood Rock. Despite the Empire's new Ironkong, the Republic corners them in 10 days. Defeated, the remnants of the Empire flee across the ocean to the Dark Continent.		H, A, K
2039	The Republic breaks into the Imperial capital, defeats the unmanned Bronze Kong guarding the palace, and searches for the Emperor, but he hides underground and escapes to Valecia Base in a Storch. The Republic follows and Zenebas flees to the Dark Continent in a Sinker, with General Danny Duncan sacrificing himself to save the Emperor.	Twinhorn Storch	B2
8/3/2039 [G] 2041 [B2]	The Zenebas Empire returns in the D-Day landings, attacking Valecia Bay with Whale Kaisers and a new army of Zoids. Not expecting Zenebas to pass through Triangle Daras and unable to communicate due to the Dimetrodon's jamming abilities, the Republic bases are unprepared and soon fall. Some guerilla groups fight back, including a group of Attack Zoid pilots called the Blue Pirates.	Dimetrodon Wardick Sea Panther Attack Zoids	G10, K, B2
~2039 [G] 2042 [B2]	The Empire tries to capture Armegen Bridge with a group of winged Iguans led by Lieutenant Colonel Frost. The Republic defeats the Iguan force but the bridge falls into Imperial hands when Ironkong Mk-IIs arrive. The Empire army then breaks through a defensive wall on the Republic's border, but is stopped by a new high-speed force led by the Shieldliger. However, the Empire is aiming to recapture the Uranisk area and the huge Zoid hidden in an underground base there...	Shieldliger Command Wolf	G11, K, B2
2043	Intercepting an Imperial transport force, the Republic learns of a new Imperial Zoid under construction, even larger than the Gojulas. They send a scout force led by Colonel Johann Ericsson to investigate the Empire facility, but the Imperial soldiers escape and blow up the facility, leaving behind nothing but a set of huge footprints.		B2
2042 [K] 2044 [B2]	The Empire's Skeleton Force attacks a Republic air base with their new 24-scale Zoids. The surviving Puterasu chase after them but vanish, their shattered wreckage being found later. The Empire has sent out their newly-completed Deathsaurer, armed with a Charged Particle Cannon and guarded by a bodyguard force of the small but powerful Zoids24. Piloted by Toby Duncan (Danny's brother), the Deathsaurer attacks a base full of Gojulas. The Republic plans to blow up the base, but the Deathsaurer shoots a hole in the earth and escapes underground. The Republic citizens evacuate to Helic City, guarded by Colonel Ericsson in his Ultrasaurus. Recognising the one that killed his brother, Toby Duncan fights and kills him, but Ericsson's dying words are praise for Danny Duncan.	Deathsaurer Deathpion Roadskipper Dontress	G12, K, B2
2042 [K] 2043 [G, K] autumn 2044 [B]	Unable to oppose the Deathsaurer, the capital Helic City finally falls and the Republic people escape through numerous secret tunnels, seeming to disappear from the Central Continent entirely.	Reddra	G13, K, B2
12/2044	The Republic army attacks Cook Base with a gun battery disguised as an iceberg, then retreats across the ocean into an iceberg-filled region. Captain Franz Hartman's force pursues them and finds what seems to be President Helic's personal Ultrasaurus, but is ambushed and wiped out by other Republic Zoids, including a second presidential Ultrasaurus - both Zoids (and their pilots) are body doubles.	Brachios	B3
3/2045	While the real President Helic commands his army from an island in Florecio Ocean, countless fake Helics lead the Republic's scattered forces in guerrilla attacks all over the continent. Some Republic generals launch an operation to capture a Deathsaurer without Helic's knowledge, but it fails, and Helic bans any further unapproved attempts.		B3
5/2045	While Zenebas begins moving all his Deathsaurers into Republic territory, Helic gathers his Ultrasauruses and converts them into carrier types, aiming to take control of Florecio Ocean. The Republic uses unmanned aquatic Zoids to lure out the Imperial fleets, then wipes them out with Pterases and Ultrasauruses. The Empire tries to counterattack with its new Reddras, but the Republic fleet is further out to sea than expected, leaving the Reddras without enough fuel to fight.	Reddra	B3
6/2045	Franz enters the Republic, claiming to be a captured Republic soldier who stole Deathsaurer operational documents. With his help, the Republic manages to capture a Deathsaurer and takes it to Helic's secret island base. But Franz brings a Roadskipper out of a compartment in the Deathsaurer's belly and kidnaps the President. He is defeated by Rosa, one of Helic's bodyguards, but she chooses not to kill him, so he escapes and remote-detonates the Deathsaurer to keep it out of Republic hands.	Megatopros Battlerover Neptune	B3
7/2045	As the Republic prepares to make a landing on Germandy Peninsula, they send a single Ultrasaurus and a few smaller Zoids to Diepp Beach on the opposite shore as a distraction. A nearby Deathsaurer takes the bait, destroying the fake landing force before realising its mistake and turning towards the peninsula. However, the dying Ultrasaurus shoots the Deathsaurer's intake fan, allowing the rest of the army to sink it easily. The Republic secures the peninsula, allowing their scattered forces to regroup via sea and escape into the Central Mountain Range.		B3
2043 to 2045	The Deathsaurer is unable to enter the rugged Central Mountain Range, so Reddras and Deathpions are sent in instead. They discover that the Republic has developed its own Zoids24 force in a secret mountain base, and guerrilla warfare breaks out.	Megatopros Battlerover Neptune	G13, K
8/2045	An injured Command Wolf pilot discovers a village made up entirely of war orphans, who chase off the pursuing Empire force using various schemes, such as hijacking a Twinhorn and causing a rockfall.		B3
9/2045	The Republic army gains control of the Southern Mountain Road linking Illusion City and Etsumi Port.		B3
10/2045	The Republic cuts off the Middle Highway across the mountains.		B3
3/2046	The Republic lays siege to the Empire's largest mountain base, aiming to cut off the northern supply routes. While the harsh winter hinders Imperial support forces, the Republic transports 5 disassembled Ultrasauruses along the secret Helic Route, then rebuilds them nearby and uses them to storm the base.		B3
2046	The Empire's Green Horn, a custom Redhorn with an Anti-Charged Particle Shield, is captured by Republic spies. Its shield technology is later used by the Madthunder.		W, K
8/2046	Having captured most of the Central Mountain Range, the Republic begins to take back the eastern plains. The force at Red River travels too far into enemy territory and is surrounded, so President Helic takes his personal Centaur to rescue them. Meanwhile, the Republic headquarters is wiped out by Franz's Deathdog, which then attacks the returning Centaur. Running out of power, Rosa (the co-pilot) forcibly ejects Helic, then lets the Deathdog bite onto the neck of the Centaur before flying into the air. She then drops both of them from 100 metres up, destroying both Zoids, although both pilots somehow survive.		B3
2046 [K] 10/2046 to 11/2046 [B]	With the Empire's supply lines now limited to the northernmost tip of the Central Mountain Range, the Republic continues their wide-scale counterattack, organising an assault force of Dibisons.	Dibison	B3, K
12/2046	President Helic proposes to the injured Rosa in a field hospital.		B3
4/2047	While the custom Dibison "Big Bad John" causes chaos in the Republic capital, a force of Megatopros follows the underground waterways to the prison and breaks out the captured Professor Chester. The high-speed Arosaurer carrying him to safety is caught by a Deathsaurer, but its head detaches and flies away.	Arosaurer	B4
6/2047	Preparing to retake their capital, the Republic tries to cut the Empire's last supply lines, but the attack force is defeated by the new Greatsabre.	Greatsabre	B4
7/2047 to 12/2047	Eccentric Republic soldiers Lewis and Martin launch the "Stove and Swallow Operation", setting up huge amounts of fake military facilities on an island to waste the Empire's resources and draw their attention away from where the real Zoid development is being carried out - inside a custom Salamander that spends most of its time airborne.		B4
11/2047	The son of President Helic II and Rosa Lauri is born. Emperor Zenebas sends him a family bracelet as a congratulatory gift.		B4
1/2048	Searching for Professor Chester, the Empire sends the Deathbird to bomb a Republic facility. It shoots down the counterattacking Puterasu force and returns to base, not realising it has been followed by the stealth Zoid Suterasu. The Republic sends in an ambush force but are themselves ambushed by the Death Shadow, which hunts them all down.		B4
8/2048	The Empire increases its production efficiency and builds up a huge army, planning to use a pincer attack to trap the Republic in the mountains and wipe them out. The Republic holds out for a while with the help of an Ultrasaurus, but Major Hobart's new Gorem picks up a fallen cannon and shoots the Ultra's gun turrets, then climbs inside the Ultra and sets a bomb.	Gorem	B4
2046 [K] 2048 [B]	Frustrated by the Republic's constant resistance and guerrilla fighting, Zenebas sends out the Empire's "strongest force", made up of Mk-II models. In response, the Republic creates its own Mk-II Force.	Greatsabre Shieldliger Mk-II Gorem	G14, K, B4
2047 [K]	Zenebas sends the new Zoid24 Gorem to infiltrate a Republic base, where it discovers the Republic's latest giant Zoid, a "T-type"...		G14
9/2048	The Empire detects another Republic facility and sends the Deathbird to bomb it, but dispatches a Gorem to infiltrate it and capture Professor Chester first. The Gorem discovers that the base is another fake, and the "new Zoids" there are just shells placed over Gojulas wrecks. It tries to call off the air-raid, but unfortunately its allies have orders to ignore all messages in case of fake transmissions, and a Republic Zoid snipes the Gorem to prevent it from escaping. Meanwhile, near Arthur City, Professor Chester has finally completed his new Zoid...		B4
10/2048	The Republic sends its entire air force to the Central Mountain Range to support its struggling mountain forces, and releases the Madthunder towards its capital while the Empire's troops are focused on the mountains. On the way to the capital is an Imperial base guarded by an Ironkong on top of a high tower, so the Madthunder uses its Magnezers to bring down the tower.	Madthunder	B4
2048	The Republic finally unveils the Madthunder, equipped with a shield able to withstand the Deathsaurer's Charged Particle Cannon. The two giants clash on Oberia Plain, with the Madthunder winning.	Madthunder	G15, K
12/2048	Major Michael Hobart lies in wait for the Madthunder with his final Deathsaurer custom, the Death Fighter. The Madthunder easily defeats it and Michael is captured by the Republic. He meets the sick Professor Chester, who asks him to complete the work on a set of prosthetic limbs (originally designed by Michael's father) in his place. The Republic recaptures their capital city, and later airdrops the advanced prosthetics into towns full of injured Zenebas soldiers.	Lidier	B4
2049	Using the powerful Madthunder division and the new flying Zoid Raynos, the Republic manages to retake its capital.	Raynos	K
2050	With the Empire in retreat, the Republic retakes all of its former territory, before invading deep into Imperial territory.		K, B5
8/1/2051	As soon as the New Year's ceasefire ends, the Madthunders surrounding the Imperial capital break through the walls and capture the city. The surviving Imperial forces gather at Valecia Bay.		K, B5
3/2051	Cornered but unwilling to hand the continent over to Helic, Zenebas sends a messenger to the Dark Continent... The Republic sends over 200 "Big Mothers", Madthunders under an Ultrasaurus shell, to attack the surviving Imperial forces on Nicaidos Island. 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 then turns on the Zenebas Empire, defeating Zenebas' personal Zoid and seemingly killing him. They capture Zenebas' daughter Elena and his adopted son Störmer (Gambino's son), with their leader (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.	Raynos Deadborder Heldigunner	G15, G16, K, B5, R
10/2051	Among the items recovered from the defeated Whale Kaiser is a document encoded with the "HZ code", which Helic and Zenebas devised when they were children. It is a letter from Zenebas to Helic, warning that the Dark Army is developing an "ultimate weapon". Hoping to destroy it, Helic sends the custom Madthunders Sea Mad and Mad Fly to invade the Dark Continent, but they are defeated by the super-powerful Dark Horn and Death Alien, and the landing fails.	Dark Horn	B5
2052	Although the war is over, nasty things are happening to the environment of the Central Continent. The young scientist Shuu (Isaac's son) discovers that the events are linked to the Dark Army, and decides to lead a scout force to the Dark Continent in Operation Triangle. However, when the force crosses Triangle Daras, they are met with Dark Zoid versions of many of their old Zenebas foes.	Cannonfort	G16, K, R
6/2052	After developing the Gunbluster and the Turtleship carrier based on tech from the defeated Whale Kaizer, the Republic sends another invasion force, which lands at Entrance Bay and controls the area within a 5 km radius after just 20 hours thanks to the Gunbluster's destructive power.	Gunbluster	B5
11/2052	A scout Puterasu discovers a secret Dark Army weapons factory 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 Mk-II in half - lengthways. But the shield of Lieutenant Krüger's Gunbluster manages to withstand the new weapon and he shoots down the Kong.	Houndsoldier Zeekdober	B5
2053	Shuu's scout force lands at the Bloody Gate, the entrance to the Dark Continent, but meet a Dark Horn force led by Störmer. They are only saved by the arrival of reinforcements - the Gunbluster.	Dark Horn Gunbluster	G17, K
2054 [K] 2053 [R]	The Republic penetrates deeper into the Dark Continent with the help of new high-speed Grade-Up Zoids. With the Salamander F2, they are finally able to break through the Devil's Maze canyon system...	Houndsoldier Gul Tiger Salamander F2	G18, K
2055 [K] 2053 [R]	The Dark Army springs their trap, releasing the super-powerful Gil Vader (piloted by Störmer). It easily defeats even Madthunders.	Gil Vader	G18, K
10/2053	The Republic's front-line base is attacked by a high-speed force, and their Turtleship is crushed by a meteor. A huge Zoid breaks out of the meteor and annihilates the base - the Dark Army's ultimate weapon, Gil Vader. It crosses the ocean and starts bombing the undefended Helic City, but meets a counterattack by Krüger's Salamander F2 and Captain Graham's Gunbluster. Graham is killed saving Krüger, who is unable to stop the Gil Vader. Around 80,000 people die in the air-raid.	Gul Tiger Salamander F2 Gil Vader	B5
2/2054	Discovering a Dark Army base after chasing a Gil Vader, the Republic airdrops a group of Kingligers from an Ultrasaurus flying boat, and they set high explosives on the Gil Vader while it is refuelling. However, the Gil Vader survives and attacks the nearby Madthunder awaiting the return of the Kingligers. Krüger uses his Salamander F2 to shield it, although the F2 saves his life by force-ejecting him just before it is hit.		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 rescue the Republic's Dark Continent forces. 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
2/6/2054	Guylos sends more than 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 Orudios's horn, causing both Zoids to crash, then self-destructs the 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
2056 [K] 2055 [R]	Nearly wiped out, the Republic quickly mass-produces the fast and agile Orudios to stop the Gil Vader. Hastily producing new and powerful Zoids such as the TransFighters, the Republic once again invades the Dark Continent, aiming to rescue the captive Zenebas.	Godkaizer Kingbaron Shoteagle	G19, K, R
2056	The Republic advances on the Guylos capital city, Darkness, in the River of Revenge operation. The Dark Army's strongest force, containing the mass-produced but powerful Gungyalado and the laser-reflecting Iceblazer, prepares to defend the capital...	Battlecougar Thundercannon Iceblazer Gungyalado	G20, K, R
11/2056	Using all their technology, the Republic creates the King Gojulas, an ultra-powerful Zoid that annihilates the Dark Army and their bases. 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 and causing a period of planet-wide upheaval later known as the Grand Catastrophe. 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 Descat	G21, K, 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.		R, K
2057 [R] 2058 [K]	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 Ex-Gurantula Valga	R, K
10/2058 [R] 2059 [K]	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. The Republic escapes, but their mission is a failure.	Barigator TS Dark Nessios Crimson Horn	R, K
1/2059	While Helic inspects a facility on the Central Continent, a captured Valga activates without any pilot and threatens the entire base, but it is destroyed by Will Craig in the Tiga Godos being created there.	Tiga Godos	R, K
2/2059	The Republic makes use of the extensive sheet ice to send the speedy King Ligers on spy missions to the Dark Continent.		R, K
3/2059	An Empire soldier realises that unlike most flight systems, the GyroCrafter Unit will not be affected by the magnetic storms, so Gul Tiger GCs - the first air combat Zoids since the Grand Catastrophe - are used to destroy the scouting King Ligers.	Gul Tiger GC	R, K

2089	While the Helic Republic and Guylos Empire are still recovering from the Grand Catastrophe, both nations organise teams to track down and recapture escaped "Stray Zoids" as a cost-effective way to rebuild their armies and recover lost technology. One such team, the Republic's EXTY 138, manages to capture a stray Iron Kong on the Western Continent.		D
10/2098	A year after the death of Emperor Guylos, his sole surviving relative, 10-year-old Rudolph Zeppelin, is crowned Emperor. Gunther Prozen, a member of a high-ranking Guylos family, becomes Regent.		F1
6/2099	Prozen declares war on the Helic Republic. Because Triangle Daras, a region full of electromagnetic storms, has become impassable since the Grand Catastrophe and now prevents a direct invasion of the Central Continent, the Empire instead sends 90 military divisions to the Western Continent of Europa, taking control of 30% of North Europa within two weeks. The Republic responds by sending in 30 divisions of their own to intercept them.		F1, K
8/2099	The two sides finally clash at Red Rust desert. Both armies target the strategic position of Mount Olympus, but the Empire is far more prepared for this war and captures the surrounding area within a week.		F1, K
9/2099	Barely clinging on thanks to their high-speed Zoids, the Republic sends a Shield Liger battalion to capture or destroy the ancient ruins at the summit of Mount Olympus, but they meet fierce resistance from the Imperial forces.		F1, K
10/2099	Finally reaching the summit, the battalion discovers that the Empire is trying to resurrect the extinct Death Saurer using super-advanced technology from the ruins. The half-built Death Saurer's self-defence instincts cause it to go berserk and attack everything around it with its Charged Particle Cannon, but L.G. Halford manages to rip out its overloading Zoid Core, which then self-destructs and wipes out the ruins. A scouting Double Sworder manages to rescue a single survivor from the battalion, Tommy Paris, along with data he retrieved about the ancient technology.		F1, K
11/2099	Having lost more than 80% of North Europa to the Empire, the Republic forces withdraw to the eastern tip of the continent.		F1, K
1/2100	The Empire begins tests on new weapons and Zoids, discovering that the Organoid System (a program based on the ancient technology from the Mount Olympus ruins) can significantly increase the strength, speed, agility and healing powers of Zoids, at the cost of making them harder to control due to increased aggression and negative mental effects on their pilots.	Geno Saurer	F2
3/2100	As the Empire's offensive on North Europa falls into a stalemate due to overstretched supply lines and guerrilla warfare from the Republic, both sides send their latest Zoids south to capture more ancient ruins and technology. Despite the efforts of Arthur Borgmann and the Republic's new Organoid System-equipped Zoids, Ritz Runstedt's Geno Saurer succeeds in retrieving an ancient Zoid Core from the Garil Ruins.	Rev Rapter Blade Liger Storm Sworder Gun Sniper	F2, K
4/2100	A force of 1000 Redlers sets out to bomb Rob Base, but suffers a crippling defeat against the Republic's new Storm Sworders.		F2
5/2100	After securing control of the skies, the Republic persistently bombs Guylos supply lines, leaving the Empire's front-line forces with critical supply shortages and buying time for a counterattack.		F2, K
6/2100	In a last-ditch attempt to turn the war around, the Republic sends in the strongest Zoids from their homeland defence force, leaving the Central Continent unguarded. An assassin force of Sinkers awaits the Neo Turtleship transporters, but the defence force shoots them down from inside the carriers.		F2, K
7/2100	Taking advantage of a stormy night when the Republic's aerial Zoids will be unable to fly, the Empire launches a massive pincer attack on Rob Base to destroy the Republic reinforcements before they are ready to start their counterattack. However, the aquatic troops are defeated by the Republic's new Hammer Head, while the ground forces (including Prozen's "personal army", the Prozen Knights) are chased off with the help of mercenary groups (including Irvine, who wins over the "unpilotable" Gojulas The Ogre). Five days later, the Empire sends three new, super-powerful Zoids to rescue the retreating ground forces and stop the Republic's advance. During one such ambush, the Death Stinger (grown from the ancient core from the Garil Ruins) takes damage and goes berserk to defend itself, wiping out both sides before retreating underground.	Hammer Head Geno Breaker Lightning Saix Death Stinger	F2, K
8/2100	After numerous custom designs and tests, the Republic creates the Attack Boosters, allowing the Blade Liger to hold its own against the Geno Breaker.		F2
9/2100	The only remaining Ultra Saurus (President Camford's personal Zoid) is remodelled into Ultra Saurus The Destroyer. Leading the Destroyer Corps, it makes its way west, wiping out entire Empire forces from great distances.		F2, K
10/2100	The battle between rivals Ritz Runstedt and Arthur Borgmann (in a Geno Breaker and a Blade Liger AB, respectively) strays into ancient ruins, where they discover that the berserk Death Stinger has been cloning itself. 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 while the rest of the army withdraws to the Dark Continent. An elite Republic team invades the base and finds an "Interface" that the Empire has just excavated, along with two new prototype Zoids. Prozen's son Wolff Muroa uses one (the Berserk Führer) to wipe out the team, but Ray Gregg steals the other prototype and tries to fight him. Wolff escapes with the Interface, but Ray brings the prototype liger to the Republic.	Elephander	F2, F3, K
1/2101	President Camford offers a truce to the Empire, but Prozen rejects it. While the Republic remodels their Ultra Saurus The Destroyer into Ultra Saurus The Carrier, preparing to invade the Dark Continent, the Empire buys some time by sending custom Whale Kings (Moby Dicks) full of unmanned Zabats to bomb the half-converted Ultra Saurus. In order to destroy the Moby Dicks, which fly too high for ordinary Zoids to attack, the Republic brings their handful of Salamanders back into service.	Spinosapper Zabat	F3, K
1/2101 [K] 3/2101 [F]	Prozen sends another attack force to Nixie Base, this time composed of Wardicks (mass-produced thanks to the Organoid System) and 10 Death Stinger KFDs (Killer From the Dark), now made safely controllable thanks to the Interface, the "missing piece" of the Organoid System. However, they are wiped out by the Republic's new Ray Force and its CAS-equipped Liger Zeroes (based on the prototype Ray captured). Wolff's childhood friend Anna Tares, one of the KFD pilots, is killed by Ray Gregg during the battle.	Liger Zero	F3, K
~2101	The Republic attempts to defend Nicaidos Island from Empire attacks, managing to defeat even Death Stingers with just two Zero Panzers. On Europa, the high-speed Mirage Corps is ambushed by stealth Elephanders, only escaping thanks to a sniper in a Buster Tortoise. Some time later, an Empire base uses the hard-to-control Geno Breaker to fight against a Salamander air-raid.		W, K
6/2101	The Republic finally launches its first Dark Continent invasion fleet, but they are met by a huge army of Imperial aquatic Zoids in the Battle of Andar Sea. On the verge of total defeat, the Republic fleet takes refuge in Triangle Daras. Their Zoids soon start to go berserk and attack each other due to the plasma storms, until a strange new Imperial Zoid appears and guides them to a safe path through the Triangle.	Shadow Fox Maccurtis Demantis Berserk Führer	F3, K
7/2101	Two weeks after the Battle of Andar Sea, now able to use Triangle Daras as a secret safe route, the Republic forces begin a full-scale landing on the Dark Continent, taking control of Entrance Bay within half a day. The Empire's defences seem far weaker than expected - and sure enough, a scouting Shadow Fox eventually spots a mysterious new Imperial group, the Eisen Dragoon (led by Wolff Muroa), wiping out the defence forces in the Republic's path. A Republic transporter bound for Europa is intercepted by Death Stingers, but they are defeated by the Gojulas Mariner guards and the transporter's cargo, which is a prototype Gojulasgiga.	Diloforce Grounchar	F3, K, W
8/2101	The Ray Force tracks the Eisen Dragoon to a secret base, where their true plan is revealed: they are Zenebas loyalists who intend to wear down both the Helic and Guylos forces equally so that the Zenebas Empire can return to power. The Ray Force's Zoids are frozen by the jamming waves of Grounchars, but they are saved just in time by the arrival of Gunblusters, which are capable of counteracting the Eisen Dragoon's jamming and E-Shields. Ray Gregg has almost defeated Wolff when the Bloody Demon, an experimental Death Saurer variant, emerges and slaughters the Ray Force. Ray uses a mixture of all the undamaged CAS parts left in the burning Hover Cargo to defeat the Bloody Demon, but Wolff rescues its pilot and escapes to rejoin the Eisen Dragoon's main force.		F3, K
~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 one of their newly-built Madthunders on a secret mission, but are attacked by a Guylos force. Prozen then airdrops a prototype Dark Spiner into the battle, intending to remote-detonate 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.	König Wolf Liger Zero X Snipe Master	W
9/2101	Well-known soldiers Rob Hermann and Karl Schwarz hold a secret meeting to discuss the Eisen Dragoon's plot, but Prozen sends a Liger Zero X to assassinate them. Schwarz (and Tommy Paris) are seriously wounded, but Hermann uses a König Wolf DSR to snipe the Zero X while it is distracted trying to destroy an almost-completed Madthunder in the nearby hangar. However, the Empire has finally managed to resurrect their Death Saurer cores (again thanks to the Organoid System), and Prozen deploys fifty Death Saurers and all of the army's reserves in an all-out assault on the Republic, leaving only his Prozen Knights and the Emperor's bodyguards in the Imperial capital Valhalla. Meanwhile, on the Western Continent, a Molga force delivering a new Chimera Core encounters the prototype Gojulasgiga, but Jasz Noguchi's Molga Rokurou Special manages to knock it off a cliff, presumably destroying it.		F4, K, W
~10/2101	The Republic develops the Cannoneer Gordos and Fire Fox to work together, but all nine Fire Foxes are stolen by an Imperial intelligence force and deployed to the Empire's Red Illusion Force, which later uses them against the surviving Republic troops on the Central Continent.		K
early 10/2101	Powerful Imperial forces attack the Republic's northern defence lines on Thrym Plateau and Bifrost Plain, but are unable to break through before Republic reinforcements arrive a few days later. Imperial Marines make repeated nighttime raids on the Republic lines at Urd Lake, hoping to break through so that they can support the Bifrost Plain forces, but 10 days later they are trapped and wiped out when the Republic airdrops mines into Urd Lake during one of the raids.		F4
mid 10/2101	While the Republic's forces are concentrated in the north, the Empire sends a strike force along the southern coastline with assistance from the Navy, destroying a third of the bridgehead at Entrance Bay and coming within 5 kilometres of the Republic's general headquarters before they are driven back with the help of the Ultra Saurus. Meanwhile, the Republic sends a decoy force to distract the main Imperial defence forces amassed on Vigrid Plain, while the Republic's main force charges across the relatively undefended Vana Plain towards Valhalla. However, the Imperial troops on Vana Plain manage to hold back the Republic's advance for five days, buying time for the Vigrid Plain forces to change course.		F4
late 10/2101	The main forces of both armies, numbering more than 100,000 Zoids and 2 million soldiers, clash along a 100 kilometre battlefront across Vana Plain, with the fiercest fighting taking place in the city of Sessrumnir. By the third day, the 20 Madthunders and 30 Death Saurers involved in this battle have all taken too much damage to fight, and the total casualties are enormous. But on the morning of the sixth day, Schwarz and Hermann arrive to call a cease-fire and reveal Prozen's conspiracy, uniting what is left of the Helic and Guylos armies against him.		F4, K
11/2101	Prozen springs his trap while most of the Guylos army is away fighting on Vana Plain, using the Prozen Knights to seize control of Valhalla and take Emperor Rudolph hostage. He proclaims that he is Gunther Prozen Muroa, son of Zenebas Muroa and founding emperor of the Neo Zenebas Empire. As the combined Helic and Guylos forces fight their way into the capital, Prozen explains the final step of his plan to Rudolph: he has hidden dozens of Death Saurer cores underneath the city, connected by pipes to his Bloody Death Saurer. The Prozen Knights are all old Zenebas soldiers who are deliberately sacrificing themselves in order to lure the Helic and Guylos forces inside the city, at which point Prozen will set off a chain reaction of self-destructing Zoid Cores and kill them all, completing his revenge and leaving nobody to stop the Eisen Dragoon. Rudolph challenges Prozen to a Zoid duel against his gold Saber Tiger, hoping for a chance to disconnect some of the Bloody Death Saurer's pipes and save his citizens, but he is quickly defeated. Just then, Schwarz's Iron Kong bursts in, shooting the Death Saurer's cockpit and giving Rudolph a chance to rip out a few of the pipes before Schwarz pulls him into a bomb shelter. Fatally wounded, Prozen presses the detonation switch, obliterating most of the city and the armies within it. Meanwhile, the Eisen Dragoon invades the Central Continent, using the jamming waves of Dark Spiners to freeze and hijack the Republic's already depleted defence forces. Led by Wolff Muroa, they conquer the western half of the continent within three weeks, taking in former Zenebas citizens and officially founding the Neo Zenebas Empire, with Wolff as Emperor.

2102 [K] 12/2101 [F4]	Five weeks after their first landing at Cook Bay, the Eisen Dragoon captures Mount Arthur Fortress, the largest fort on the road to the Republic capital. Two weeks later, after their requests for surrender are ignored, they invade the capital, not realising President Camford is secretly Elena, daughter of Zenebas and thus Wolff's aunt. Camford flees in a Saberlion, which narrowly escapes a pursuit force of Guntigers. However, when pilot Tommy Paris checks the hatch where Camford was hiding, it is empty, apparently having opened by accident during the escape.	Saberlion Guntiger	F4, K
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 daughter of a Zenebas bodyguard, not an heir to the Neo Zenebas Empire, and the mask is claimed by an Imperial force.		W, K
1/2102	The surviving remnants of the Republic army begin to return to the Central Continent, hiding in the Central Mountain Range and working on a new Zoid whose blueprints were given to Tommy Paris by President Camford before their escape. Rudolph and Schwarz take charge of the Guylos survivors on the Dark Continent, while the citizens of the Central Continent come to accept their new Neo Zenebas rulers.		F4
2102	To prevent invasions from the Republic remnants on other continents, the Neo Zenebas Empire deploys the oceanic defence force Trident, consisting of just three Marine Kaisers and the aquatic Zoids carried aboard them, to guard the oceans around the Central Continent.		D
~2102	An attempt to retake the Republic capital is thwarted due to the presence of Dark Spiners in the defending forces.		X1
1/2103	The Neo Zenebas Empire launches a continent-wide mop-up operation, destroying or capturing more than 350 Republican Zoids and taking more than 3000 prisoners in two weeks, but this is less than 10% of the suspected number of remnant Republican Zoids, so the operation is considered a failure.		F5
2103	Investigating reports of Republic remnants on the Western Continent, a Sturm Tyrann pilot from Neo Zenebas encounters an old Guylos acquaintance in a Raven Raptor. The two Imperial forces fight each other, not realising that the Republic leaked the reports deliberately as a trap. A custom Gojulasgiga attacks the pair, but the Raven Raptor pilot distracts it long enough for the Sturm Tyrann pilot to escape.		W, K
2102 [D] 2104 [K] 3/2103 [F5]	The Eastern Continent corporation ZOITEC invents Blox, modular Zoids with artificial cores that can exchange parts or combine with other Zoids. They initially offer the technology to the Neo Zenebas Empire, but the Empire's aggressive policies prompt them to give the technology to the Republic remnants instead. Meanwhile, rival corporation Zi-ARMS provides the Empire with autonomous "Chimera Blox", but the fighting instincts of the Chimeras sometimes override their programming, causing them to attack indiscriminately.	Leoblaze Nightwise Flyscissors Demonshead	K, D, F5
~2104	Spotting a pattern in the movements of Marine Kaiser 1, the Republic forms a plan to ambush it in Deldaros Ocean. They send in an aerial force from New Helic City, an aquatic force from the oceanic base Starfish, and a "Peacemaker Force" of Republic-coloured Geno Saurers from Rob Base, taking serious damage but successfully destroying the Marine Kaiser. Upon recovering the wreckage, they learn that the Neo Zenebas Empire has been researching obscure, locally-developed "X Zoids" in hopes of producing a super-powerful new Zoid, which prompts the Republic forces to accelerate their plans to retake the Central Continent.		D
4/2104	Following their previous success, the Republic manages to sink Marine Kaiser 3 in the Battle of Deldaros Ocean.		D
10/2104	The Republic wins the Battle of Florecio Ocean, opening the path for a large-scale landing on the Central Continent later that year.		D
10/2105	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. The Republic soldiers consider self-destructing the almost-finished Gojulasgiga to keep it from falling into the Empire's hands, since its anti-jamming armour is still incomplete, but the Ogre manages to destroy all the Dark Spiners on its own and the Gojulasgiga proceeds to defeat the rest of the Black Dragoon.	Gojulasgiga Buster Eagle	X1, F5
~2105	The Diablotiger arrives from the future to battle the ancient Cyclops, and old Republic pilot Gogo Satie uses a custom Salamander to oppose Vern Wendsor's Saint Gale.	Lord Gale	K
01/2106	The Neo Zenebas Empire reintroduces the Dimetrodon, further increasing their strength in electronic warfare. Judge Lyre ambushes an Imperial scout platoon in the Forest of Ardannes and singlehandedly defeats 10 Zoids, but is killed by a suicide attack from Capri Conrad.		X2, F5
02/2106	Verditer Rowen and Winner Kidd attack an Imperial supply force at Lykan Canyon as an unauthorised test run in order to convince the Republic to mass-produce the Gorhecks, whose Crystal Radar can neutralise the Empire's jamming waves.		X3, F5
03/2106	The Republic army begins its counterattack, invading Cook Fortress while the Empire is distracted by empty Guylos carriers arriving on the coast. Protected from jamming by the Gorhecks and surrounded by a guard unit of Arosaurers, the Gojulasgiga manages to defeat the Empire forces, including a Death Saurer, and captures the fortress.		X4, F5
04/2106	The Empire introduces manned Blox Zoids such as the Lord Gale and Deantler to control the smaller Chimera Blox.	Deantler	X5, K, F5
~2106	The Republic uses Rob Hermann's "disappearance" during an anti-jamming armour test as an excuse to create a "memorial force" containing the Heavy Arms König Wolf, although his disappearance was actually just faked for PR reasons and he soon "returns".		K
08/2106	The Neo Zenebas Empire completes the Seismosaurus, equipped with a Super-Focused Charged Particle Cannon capable of destroying the Gojulasgiga from extreme distances. A team of 10 Seismosauruses use Wilson River to get within firing range of Cook Fortress undetected and blast it open just as Republic reinforcements are arriving from the Dark Continent, allowing the Neo Zenebas ground forces to break in and wipe out many of the survivors, though some manage to escape thanks to desperate counterattacks from Dew Eld, the former Ray Force members and Ritz Runstedt, fleeing to the Eastern Continent.	Seismosaurus Styluarmor Scissorstorm Laserstorm	K, F5
autumn 2106	Completely defeated, the remnants of the Republic army escape to the Eastern Continent. Fearing a Neo Zenebas invasion, ZOITEC decides to throw its full support behind the Republic.		K
~2106 [K] 6/2108 [F5]	The Republic sends a prototype Gairyuki (based on a Tyrannosaurus-type wild Zoid offered by the Guylos Empire and capable of absorbing Charged Particle attacks to power its own weaponry) and some support Blox aboard a stolen Dragoon Nest to an island near Cooper Port, attacking the local defence force as a combat test in preparation for their return to the Central Continent.	Gairyuki Dispelow Evoflyer	K, F5
10/2108	Despite the Empire's fortifications along Wilson River, which lies across the Republic army's intended route to their former capital, the Republic's new transforming Zoid Leogator manages to capture Cook Fortress in a massed ambush and hold off subsequent Imperial reinforcements.	Leogator Dimetroptera	X6, F5
11/2108	The Republic army captures Mount Arthur, an important strategic point close to Helic City, with the help of the transforming Dimetroptera.		X7
2107 [K] 12/2108 [F5]	A group of 29 Ligerzero Phoenixes (piloted by the remnants of the former Ray Force) invade the heavily-guarded Crockett City, defeating the army of Chimera Blox within and seemingly clearing the path for Gairyuki reinforcements. However, they discover a Seismosaurus inside, and their attempts to capture it are thwarted by Wolff in the new Energy Liger, though they do manage to capture some other Zoids (including two Liger Zero Xes and a newly-built Jet Falcon) and the city itself.	Phoenix Energy Liger Jet Falcon	K, F5
spring 2109 [X8] 1/2109 [F5]	The Republic army sends their nearly 30,000 remaining Zoids along three routes towards the former capital, but the smaller southern and central groups are blocked by overwhelming numbers of enemies, while the larger northern group meets oddly little resistance. Meanwhile, Ray Gregg, Moonbay and Tommy Paris investigate a suspicious site in the Northern Mountain Range, discovering a superweapon called the Seismo Cannon guarded by Wolff. Ray's Zero Phoenix is no match for Wolff's overcharged Energy Liger, but he manages to form the Liger Zero Falcon instead and shoots the Seismo Cannon's core. However, this triggers an energy overload situation like the one Prozen set up in Valhalla, threatening to destroy everything in a 100km radius, so Wolff and Ray work together to divert some of the energy through the Energy Liger and Zero Falcon, limiting the size of the blast. With the Republic's northern forces saved and Emperor Muroa seemingly dead (though it is implied he survived and went into hiding), acting Imperial commander Signer Feuer secretly contacts Republican commander Rob Hermann to arrange a ceasefire.		X8, F5
~2109	War trials are held, the Neo Zenebas Empire is officially disbanded, and a new president of Delpoi is elected, uniting the continent and finally ending the war.		F5
2109	The Isurugi brothers use their Shadow Arm Lizards to investigate the mad scientist Zalca and his new Death Stinger ZS on Nicaidos Island.		K

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. The megacorporation 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.	Whitz Wolf Savinga	K, D
6/2230	Rival company Zi-Arms learns of the tiger cores and attacks ZOITEC with their own fusion Zoid, the Decalto Dragon. ZOITEC's new Zoids combine into Whitz Tiger to oppose it, but the control system quickly overloads and the Decalto Dragon escapes, kidnapping ZOITEC's director.	Death Raser Parablade	K, D
7/2230	In order to rescue their director, ZOITEC hurriedly constructs the second legendary tiger, Rayse Tiger, and sends it to invade the Whale King that acts as the flying fortress of Zi-Arms. However, with the director's knowledge and the red tiger core, Zi-Arms has already completed the final legendary tiger Zoid, the Brastle Tiger...	Rayse Tiger Brastle Tiger	K, D
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 three tigers join forces to defeat it, and the damaged Whale King falls to the surface, taking all four Zoids with it.		X12, D
the far future	In the Beith Republic, Zoids are used for constructive purposes as well as in illegal "ZiEL" tournaments. However, the Dynas Empire discovers the Changemize technology that allows Blox Zoids to combine, and sends their new Groundrago to attack the Republic capital. Unable to fight it alone, the Republic Army's Zoids fuse into the Bitegriffon, but the Groundrago splits into its component Zoids, cornering the Bitegriffon with superior tactics. 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 is sent on a mission to recapture the Republic capital...
