"Rain Dance!" Magnus commanded loudly, simultaneously revealing his Z-Power Ring.
The twin cannons on Blastoise's back immediately fired two jets of water toward the sky.
The sunny battlefield was instantly covered by dark storm clouds, and torrential rain began falling within seconds. Blastoise's body became shrouded in prismatic light as it underwent its transformation.
It completed MEGA Evolution while simultaneously using Rain Dance.
Enter Mega Blastoise. The massive cannon now mounted on its back made the previous twin barrels look like mere water guns by comparison. Those smaller cannons had been relocated to Mega Blastoise's muscular arms.
Unown symbols wrapped around both the main cannon and arm-mounted barrels, giving them an otherworldly, almost enchanted appearance - as if the ancient script was powering up the weapons themselves.
But Magnus wasn't finished yet.
Facing a legendary Pokemon, he was showing the highest level of respect possible.
He withdrew Mega Blastoise back into its Pokeball, then enlarged the sphere and released it again.
BOOM!
The entire battlefield shook violently!
Introducing Dynamax Mega Blastoise.
The standard Totem size had been amplified to truly colossal proportions. This Mega Blastoise was several times larger than even normal Dynamax Pokemon. Fortunately, the National Stadium had been constructed with such scenarios in mind, the battlefield was enormous, though even so, the gigantic Mega Blastoise dominated the space impressively.
That terrifying size commanded respect from everyone present.
The back of the Dynamax Blastoise bristled with cannon barrels, making it resemble a mobile fortress when viewed from behind. This was the result of MEGA Evolution followed by Dynamax, the main cannon from MEGA Evolution had become the primary weapon, while the twin barrels served as left and right auxiliary guns.
The colossal Mega Blastoise stood on the battlefield with three rapidly spinning red clouds hovering above its head, eyes flickering like a world-destroying mega fortress.
The overwhelming presence was suffocating!
"Electric Terrain," John responded calmly, taking advantage of Magnus's setup time to establish his own field advantage.
Zeraora slammed both fists against his chest.
Brilliant lightning erupted suddenly, spreading in all directions like a tidal wave.
Using the battlefield walls as boundaries, a dazzling pure white cage of electricity formed around the arena. The only thing that could penetrate this electric barrier was the rain falling from above.
"Thunder!" John called out sharply.
His opponent had set up rainy weather, it would be embarrassing not to capitalize on it with Thunder.
Zeraora raised one hand toward the storm clouds.
A white Thunder Dragon emerged from the dark, rain-heavy clouds. In an instant, the heavens split apart as endless lightning bolts descended.
A thunderous waterfall hung suspended in the sky!
Magnus's expression darkened. Calling for rain in front of an Electric-type Pokemon meant he'd already prepared for his opponent's inevitable Thunder attack.
But John's Zeraora's Thunder was completely unreasonable!
Unreasonable?
Not at all.
The legendary Pokemon's move power was already doubled by its divine nature, and with Electric Terrain boosting it further, it would be strange if Zeraora couldn't unleash such devastating attacks.
Magnus quickly pulled out a Z-Crystal and pressed it onto his Z-Power Ring.
"Z-Move, Tectonic Rage!"
The colossal Mega Blastoise immediately crouched down and bombarded the ground with massive punches.
In the next second, the earth collapsed as its huge body suddenly fell into an endless black abyss.
The lightning waterfall crashed down, bombarding the ground and easily tearing through the surface defenses to penetrate into the abyss, but it felt like hitting nothing solid.
Mega Blastoise had dodged successfully.
"Surprisingly agile," John muttered appreciatively.
While Dynamax Pokemon were essentially magnified projections, controlling energy and body movement inevitably became more difficult. To control a Dynamax body like it was normal size showed that this Blastoise had deep mastery of the Dynamax phenomenon.
"Zeraora, take to the air!" John commanded.
If his guess was correct, the Dynamax Mega Blastoise's next attack would come from underground.
Magnus silently pulled out another blue Z-Crystal and pressed it onto his Z-Power Ring.
"Z-Move: Boundless Sea Emperor!"
John immediately became alert, he'd heard of this move before.
Judging by the Z-Crystal's color, it should be a Water-type Z-Move. Besides Primarina's "Oceanic Operetta," the only common Water-type Z-Move was "Hydro Vortex."
This "Boundless Sea Emperor" appeared to be Magnus's custom creation.
RUMBLE!
A deep vibration resonated through the battlefield.
After the previous Tectonic Rage had destroyed the ground into distorted rubble, it had now become a complete abyss. Using the battlefield walls as boundaries, the ground had become a seemingly bottomless crater.
BOOM!
A muffled sound echoed from the depths of the crater.
This time, Zeraora truly had nowhere to run.
After all, going any further would mean leaving the official battle area entirely.
That thought barely crossed John's mind.
The moment azure torrents became visible, Zeraora had already dodged into the sky above the battlefield at speeds comparable to teleportation.
But the water jets didn't scatter in all directions, they locked onto Zeraora's position like guided missiles and pursued relentlessly.
The azure torrent erupted from the abyss, spiraling through the sky like a massive drill bit attempting to pierce the heavens themselves.
Even the audience could feel vibrations through their seats.
Looking at the soaring spiral water column, John could now confirm that Magnus's "Boundless Sea Emperor" was based on the Z-Move "Hydro Vortex."
If that was all it was, then this move was simply an enlarged version of Hydro Vortex.
Faced with such an intense situation, John raised an eyebrow slightly, it was time to use his trump card.
Through the swirling, twisting water flow, John could see the Dynamax Blastoise's mountain-like body retracting into its shell and spinning rapidly mid-air while continuously shooting water from all its cannon ports.
However, what made this different from a regular Hydro Vortex?
Fortunately, Zeraora had managed to avoid it.
The azure water column suddenly exploded from its center.
That spiral force became like a tornado, and with the explosion, brought endless water cascading destructively in all directions.
