Alabasta is a superpower, surrounded by the sea.
Because of this, Alabasta's coastline is incredibly long.
Facing enemies who might attack anytime, anywhere, it's crucial to predict their routes and defend accordingly.
To achieve this, the Fish-Man warriors within the Four Seas Alliance have shown their strength.
With the efforts of the Fish-Man warriors and a simulated sand table created by Ryan Rowan himself, the Four Seas Alliance's coastal defense is like an iron wall.
While they can't immediately engage sea-borne enemies the moment they're spotted, they can provide early warnings, preventing surprise attacks.
...
However, there's a reason why the "Four Emperors" are called the "Four Emperors."
Each of these top pirates on the sea is an "anomaly."
"Anomalies" are people who cannot be understood through common sense.
This is why Kaido used his powers to summon flame clouds, lifting the entire Onigashima and attacking Alabasta with an entire island!
The attack wasn't through the usual sea route, but directly from high in the sky.
Without a doubt, this move caught the Four Seas Alliance completely off guard.
If not for Ryan Rowan single-handedly creating the bizarre and powerful Sand Giant, Dalton and others defending the port town of Nanohana would have had no way to stop the aerial Onigashima.
If Kaido had been allowed to drive Onigashima straight into Alabasta's heartland, the entire battle would have become incredibly chaotic.
The current situation is the result of Dalton and others fighting with their lives.
...
However, most people in Alabasta never realized one thing.
That is, the "anomaly" that "Beasts" Kaido possesses is far more twisted than most people can imagine.
Most people on this sea believe any one of the "Four Emperors" has the power to destroy an entire country single-handedly.
But when facing Alabasta, guarded by Ryan Rowan, "Golden Dawn," "Beasts" Kaido didn't attack directly. Instead, he went to another country first.
That country is called the "Totto Land Kingdom," also known as "Whole Cake Island."
And the queen of this kingdom is a "Four Emperor" known by the nickname "BIGMOM" - Charlotte Linlin!
...
In fact, there's a hidden past between "Beasts" Kaido and "BIGMOM" Charlotte Linlin.
They were both part of the previous era's mightiest pirate crew - the Rocks Pirates.
During those days, Charlotte Linlin claimed to have treated Kaido like a younger brother, and even gave him one of the sources of his current power, the "Fish-Fish Fruit, Mythical Zoan, Azure Dragon form" Devil Fruit.
Later, with the combined efforts of pirates and Marines, the Rocks Pirates were destroyed, and their many strong members scattered across the sea.
"Beasts" Kaido and "BIGMOM" Charlotte Linlin were among them.
They each created the Beasts Pirates and the BIGMOM Pirates, ruling their domains.
Although they were in the same pirate crew before, Kaido and Big Mom's relationship wasn't smooth.
As fellow "Four Emperors," neither was willing to be subordinate to the other, leading to frequent friction, sometimes even escalating to small-scale wars.
But Kaido and Big Mom never fought head-to-head.
They both knew that a war between two "Four Emperors" could change many things and would be detrimental to their respective plans.
...
And not long ago, Kaido brought a pot of fine wine and set foot on Totto Land's main island - Whole Cake Island!
Facing the heavily guarded BIGMOM Pirates, Kaido laughed heartily and proposed his plan to Big Mom.
...
That meeting didn't last long.
In the end, the BIGMOM Pirates saw Kaido and Big Mom with their arms around each other, drinking fine wine and laughing heartily.
"We're allied, allied!"
"Call all my little ones, let's have a feast!"
"It's nice to do this once in a while, mahahahaha!"
"..."
...
No one knows what Kaido said to Big Mom, not even the close confidantes of the BIGMOM Pirates.
The only thing they knew was this:
The Beasts Pirates and the BIGMOM Pirates had officially formed a pirate alliance!
And the first thing their alliance would do was to launch a war against the superpower "Alabasta" in the first half of the Grand Line!
Among them, the Beasts Pirates chose to use Onigashima as their vehicle for an aerial attack on Alabasta!
And the BIGMOM Pirates utilized Big Mom's Superhuman-type Soul-Soul Fruit ability to infuse souls into inanimate objects, creating special beings with independent consciousness called "Homies."
Using a Homie cloud, the BIGMOM Pirates also made their ship, the Queen Mama Chanter, float in the air.
The BIGMOM Pirates also intended to launch an aerial attack on Alabasta!
...
Naturally.
From any angle, an aerial attack is a foolproof strategy.
Everyone knows the Four Seas Alliance has many Fish-Man warriors, so a direct sea attack would give them a chance to prepare.
In that case, attacking from the sky would surely go unnoticed!
...
Is that really true?
Not at all!
The Four Seas Alliance's reach extends far beyond the sea's surface.
In the sky, there's also an aerial unit led by the Sky People "Habu"!
They have been waiting in Alabasta's skies for a long time.
However, due to the extreme difficulty of training and other reasons, the Four Seas Alliance's aerial unit is small and insufficient to cover Alabasta's entire airspace.
But under Habu's command, this aerial unit has strong support capabilities, able to rush to various parts of Alabasta at the fastest speed!
...
Now, long before the Queen Mama Chanter descended near the Fish-Man Village, Habu was already rushing here with the mobile forces.
When Big Mom officially appeared, the exiled army, led by "Quack" Hiruluk, also finally showed up at the Fish-Man Village!
They stood on the shore, facing the pirate crews bearing the name "Four Emperors"!
"Quack" Hiruluk adjusted his hat and smiled:
"Eating too much candy isn't good for your health, ma'am..."
...
This is, in the future, the exiled army that the world will call the "Strongest Army on Land."
And now, "the future" has begun.
Facing the onslaught of the BIGMOM Pirates, the exiled army took their first step...
