Primal forms clashed with power that the volcanic arena amplified.
The elemental war Sasuke had named was no longer metaphor, it was reality manifesting through beings whose ancient power exceeded what modern combat typically produced.
"Lava Plume!"
Magmortar's attack didn't just target Blastoise. It commanded the arena itself.
Lava erupted from the pools surrounding the battlefield, molten rock rising in columns that transformed the entire combat space. The floor that had been relatively safe became hazard that a single misstep could make fatal.
"Dodge!"
Blastoise retreated, aerial positioning impossible for its species. The massive Water-type navigated between lava geysers that kept erupting, safe zones shrinking with every volcanic burst.
"Limited movement," Mei observed with satisfaction. "Can't dodge what covers everything."
"Hydro Cannon!"
Blastoise's ultimate Water attack didn't aim at Magmortar.
The devastating water pressure struck lava that had coated the battlefield, superheating on contact, then rapidly cooling the molten rock into obsidian that became solid footing.
Tactical terrain modification.
Where lava had threatened, black glass platforms now provided safety. The battlefield transformed from Fire advantage to something approaching neutrality.
"Creative!" Mei acknowledged with genuine appreciation. "Using your ultimate move on environment rather than opponent. Your brother would approve."
"But not enough!"
"Overheat!"
Maximum Fire-type power. Everything Primal Magmortar could generate concentrated into single devastating attack.
Blastoise couldn't dodge, the obsidian platforms provided safety from lava but limited mobility. The Fire assault struck shell that had been designed to withstand exactly this.
High defense endured what lesser Pokémon couldn't have survived.
But damage accumulated significantly.
Blastoise emerged weakened, shell showing stress fractures that the battle's intensity had created.
"Counter now," Sasuke commanded.
"Skull Bash!"
The physical technique charged through the attack's aftermath, Blastoise becoming projectile that Fire-type weakness couldn't diminish. Shell-first impact against Magmortar with force that even lava empowerment couldn't entirely absorb.
Both Primal Pokémon staggered.
Both heavily damaged.
Neither yielding.
"Gigantamax!"
Mei's command triggered transformation that exceeded Primal alone.
Magmortar grew to one hundred fifty feet, its Dynamax energy combining with Primal form to produce something that mythology would have struggled to describe. Volcanic titan whose arms had become actual lava cannons. Presence that made the arena seem small despite its massive scale.
"Dynamax!"
Sasuke's counter matched escalation.
Blastoise expanded to similar scale, oceanic fortress whose shell now resembled island more than carapace. The cannons that defined its species multiplied into dozens, each barrel capable of water pressure that could have powered cities.
Kaiju battle.
Ultimate phase.
"G-Max Wildfire!"
Magmortar's signature Gigantamax move created flames that didn't simply damage, they persisted. Fire that remained on the battlefield, burning everything it touched turn after turn.
The arena became inferno.
Blastoise took residual damage despite not being directly hit. Every moment spent in the G-Max Wildfire's zone meant accumulating burns that even Water-typing couldn't entirely prevent.
"Must end quickly," Kiyomi calculated. "The residual damage will overcome Blastoise before direct attacks do."
"G-Max Cannonade!"
Blastoise's counter came with water volume that exceeded individual attack capacity.
Dozens of barrels fired simultaneously, each one launching Hydro Pump-level pressure in coordinated bombardment. Water wall that advanced toward Magmortar with force that should have overwhelmed anything in its path.
But Magmortar's lava armor held.
The Fire-type had drawn molten rock from the arena's pools, coating itself in protection that water could erode but not immediately penetrate.
"Both strategies: attrition," Miyuki observed. "Whoever outlasts wins."
Two minutes of Dynamax remained.
The environmental damage had grown extreme, Wildfire still burning, water flooding sections that Cannonade had struck, steam filling air that already exceeded safe temperatures.
And the volcano itself was responding.
"Increased geological activity," the referee reported through communication systems. "Battle energy may be triggering sympathetic response."
The Dynamax power that both Pokémon generated was feeding into the same volcanic energy that the arena had been built to channel. The mountain was waking.
"Dangerous levels," monitors warned. "Prepare for potential evacuation."
One minute remaining.
The final exchange approached with inevitability that both trainers recognized.
"G-Max Wildfire, maximum!"
Mei committed everything remaining.
Magmortar didn't just use the technique, it channeled the volcano itself. Lava rose from every pool simultaneously, drawn into attack that the Fire-type became conduit for.
Ultimate Fire assault.
Geological power weaponized.
"G-Max Cannonade, everything!"
Sasuke matched the commitment.
Blastoise drew moisture from everywhere available, air, steam, and reaching beyond the arena to the ocean that surrounded the volcanic island. Water pressure that exceeded what the Pokémon alone could generate.
Bond's full power.
Ultimate Water assault.
Collision.
Fire and Water met at the arena's center with force that neither element could entirely overcome.
Steam explosion.
Massive.
The entire arena disappeared behind vapor that the impact created. Spectators shielded eyes. Protective barriers strained against pressure waves. The volcano rumbled with response that the clash had triggered.
Dynamax ended.
Both Pokémon returned to normal size, Primal forms barely maintained.
Smoke cleared slowly.
The battlefield revealed itself.
Magmortar stood in a lava pool, one of the few remaining, but enough. The Fire-type drew strength directly from the molten rock, regenerating damage that the water assault had inflicted.
Blastoise perched on an obsidian platform it had created earlier. The Water-type was exhausted, shell cracked, steam rising from overheated systems.
Both conscious.
Both capable of continuing.
But environment was deciding the factor.
"Blastoise is overheating," Miyuki diagnosed from the stands. "Critical levels. It can't sustain combat much longer."
"Magmortar is energized," Kiyomi added. "Every moment in that lava helps it recover."
Home field advantage. The reality that type matchups alone couldn't overcome.
"Must finish now," Sasuke calculated.
One move. All or nothing.
"Blastoise, trust me!"
The bond between them synchronized perfectly. Years of partnership. Months of intensive training. Everything concentrated into mutual understanding that exceeded verbal command.
"Hydro Cannon, into the lava beneath Magmortar!"
Unconventional target.
The ultimate Water attack didn't aim at the Fire-type. It aimed at the power source the Fire-type had been using.
Water struck molten rock with force that geological processes rarely experienced.
Flash steam.
Instantaneous expansion of superheated vapor created explosion from beneath Magmortar rather than impact from above.
The Fire-type launched upward, ejected from its lava pool by pressure that the attack's interaction had generated.
In the air.
Away from power source.
Vulnerable.
"Ice Beam!"
Follow-up came before Magmortar could fall.
Ice-type energy struck the airborne Fire-type, coating its form in frost that volcanic heat should have prevented. But disconnected from lava, Magmortar's temperature had dropped enough for ice to form.
Frozen.
Suspended in crystalline prison.
Then falling.
Impact shattered ice.
Magmortar crashed onto obsidian platform, the frozen coating breaking but leaving the Fire-type stunned. It tried to move toward the nearest lava pool, instinct driving it toward the power source it needed.
"Water Pulse!"
The final attack wasn't devastating in raw power. But it carried secondary effect that proved decisive.
Confusion.
The technique's thirty percent chance activated. Magmortar's orientation scrambled. The Fire-type stumbled in wrong directions, unable to find the lava pools that survival required.
Without heat source, it weakened.
Without orientation, it couldn't recover.
Eventually, inevitably, Magmortar collapsed.
"Gym Leader's Pokémon is unable to continue!"
The referee's declaration echoed across an arena that had witnessed something extraordinary.
"Winner: Sasuke Uchiha!"
