When a Filipino Got isekai'd with A Twist!
"Only i can summon those!"
Chapter 16: Cosmic Breaker!
Astaroth's wings unfurled like a storm—each flap sent waves of molten wind through the broken ruins around him. Lava dripped from his claws as his obsidian horns glowed red-hot. "So… the gladiator comes to play," he sneered, his voice carrying the distorted echo of countless souls he'd devoured.
Inside the Cosmic Black Barbatos Lupus Rex, Cane gritted his teeth, gripping the controls tightly. The cockpit's crimson light flickered with each pulse of the reactor core. His visor glowed with data, the mech's AI alerting him of incoming heat surges.
"Playtime's over," Cane muttered. He slammed both foot pedals—Barbatos rocketed forward like a black comet, trailing arcs of cosmic energy. His Tail Blade lashed out first, slicing across the air toward Astaroth's chest.
The Demon King of Wrath raised his arm, catching the blade with his molten gauntlet. Sparks and embers burst on contact. "You think your toys can hurt me, mortal!?"
Cane smirked. "Let's find out."
He twisted the control stick, activating Cosmic Overdrive. Barbatos's thrusters flared violet, energy pouring through the armor plates. The mech's Ultra Hard Claw shot forward—grabbing Astaroth's wrist, crushing the molten armor until it cracked.
Astaroth roared, his wings erupting into fire. The blast hurled Cane back; alarms screamed across the cockpit. Barbatos skidded through debris, metal grinding against stone.
Cane's knuckles whitened on the controls. "Damn, his output's increasing…"
"Cane!" Metatron's voice chimed through the comms, steady and precise. "Warning: Subject Astaroth's energy levels exceeding threshold. Recommend evasive maneuver—his attack pattern mimics berserker combat mode."
"Tell me something I don't know!" Cane barked, slamming another lever forward. Barbatos dashed sideways, narrowly dodging a fiery beam that vaporized an entire cliffside.
The next instant, Astaroth was already there—closing the gap, claws wreathed in magma. He swung, and Barbatos crossed its forearms in defense. The impact was brutal, enough to shake Cane inside the cockpit. The pressure gauge spiked into the red zone.
"Your fury's blinding you," Cane growled through gritted teeth, forcing the mech to stand firm. "That's why you'll lose."
Astaroth's grin widened. "Lose? You think this is rage?" His entire body ignited—his veins burned through his skin like molten cracks. "This… is pleasure!"
He drove his flaming fist into Barbatos's chest. The armor dented, alarms wailed. Cane retaliated with a full swing of the Tail Blade, severing one of Astaroth's horns. The demon roared, wings thrashing, magma spilling like blood.
"Come on, you bastard!" Cane shouted, boosting upward. Barbatos launched into the sky, spinning its mace before slamming it down in a vertical arc. The blow crashed against Astaroth's head, sending shockwaves that flattened nearby ruins.
But Astaroth only laughed, catching the mace mid-swing. "You're strong, gladiator. But strength without chaos… is meaningless!"
He yanked Barbatos closer, claws piercing into the mech's shoulder armor. Inside the cockpit, Cane felt the tremor vibrate through his entire body. Warning lights flashed red.
"Metatron!" Cane yelled, forcing the controls to stabilize. "Status of the battlefield!?"
"Current estimate: Allied forces losing ground. Summons from Kieth's army—Zoids, Transformers, and Terminators—have less than ten minutes of combat time remaining."
"Tch." Cane clenched his jaw. "Then I'll make this quick."
He triggered Core Resonance Mode—the mech's reactor pulsed, light flooding the cockpit. Barbatos's eyes blazed bright blue, its armor expanding slightly as energy surged through every joint.
Astaroth's expression twisted into delight. "Finally! Now show me that fury, human!"
Cane roared as Barbatos drove its claw straight through Astaroth's abdomen, energy bursting from the impact. The demon countered, impaling Barbatos's chest with his molten talons. Both combatants locked in a brutal stalemate—two monsters tearing at each other midair, their clash lighting up the entire battlefield like a second sun.
Smoke. Fire. Sparks.
And somewhere in the distance, Kieth's voice echoed over the radio:
"Cane, hold the line! Josh's moving to assist Chris—buy them time!"
Cane spat blood and grinned. "Time's all I need."
Barbatos's claws tightened. The cosmic light in its eyes turned white-hot—ready to drag the Demon King of Wrath/Fury down to hell with him.
Barbatos's reactor howled, the cockpit glowing brighter than a sunrise. Cane's heartbeat pounded in his ears, syncing with every thrum of the mech's core. The heat inside was suffocating, the warning alarms blaring nonstop—
[WARNING: Structural integrity 23%... Reactor overload imminent!]
"Come on, come on!" Cane muttered, wiping the blood trickling from his nose. "Hold it together, you damn beast!"
Outside, Astaroth's claws were still embedded deep in Barbatos's chest. The Demon King's laughter rolled like thunder, echoing across the scorched landscape.
"You think you can burn brighter than me, mortal!? I am wrath incarnate!" he roared, tearing his claws free. Lava spewed from the wounds as the ground itself trembled beneath them.
Cane gritted his teeth and slammed the throttle forward. Barbatos's boosters flared to life, slamming into Astaroth's gut with enough force to drag both of them through a ruined fortress wall. Stone and steel shattered in their wake.
"Let's see how much wrath you can handle!" Cane shouted.
Barbatos raised its Ultra Hard Mace, spinning it mid-flight. With a brutal swing, he smashed Astaroth across the jaw—once, twice—then brought the mace down on his skull. Each hit cracked the air like lightning.
But Astaroth didn't fall.
The demon caught the mace barehanded. Flames roared up his arm, melting through the metal.
"Impressive," Astaroth grinned, "but you're stalling. Your power is fading."
Inside the cockpit, the temperature spiked. The AI blared:
[Power reserves at 11%... Core Resonance unstable… warning: arm actuator failure imminent.]
Cane slammed a fist on the control board. "Don't you dare quit on me now!"
He switched to manual resonance override—a dangerous move that forced his own life force into the Gundam's systems. His veins glowed faintly blue as the cockpit reacted, syncing his heartbeat with Barbatos's core.
Metatron (through comms): "Cane! You're exceeding the limit! If you keep pushing, your life force will drain completely!"
Cane: "Then I'll die standing! Tell Kieth I'm not going out without breaking this bastard's jaw!"
Barbatos's armor began to glow—a mixture of black and silver streaks swirling together, cosmic energy spilling from every joint. Astaroth snarled, recognizing the shift.
"What is this…?"
"My fury." Cane's voice was low, steady, dangerous. "But not blind like yours."
The two collided again—Barbatos ducked low, drove a knee into Astaroth's ribs, then used the Tail Blade to sweep his legs. The demon caught himself midair, only for Cane to boost upward, meeting him head-on.
They clashed in the sky—one wrapped in holy cosmic energy, the other in hellfire.
The impact was so massive it distorted the air itself. A blinding explosion erupted—half black, half red—followed by silence.
Back at the command post, Kieth slammed his fist on the console. "Metatron! Status report!"
Metatron: "Analyzing… Cane and Astaroth's energy signatures are both unstable. Estimated combat time left for summoned units: seven minutes, thirty-four seconds."
Kieth's jaw tightened. On the battlefield map, the icons representing the Zoids, Transformers, and Terminators were blinking red—one by one, they were being wiped out. The Terminators were falling back in clusters, the Zoids heavily damaged, and even the Transformers were showing critical system loss.
"Damn it…" Kieth muttered. "They're not gonna last much longer."
Metatron: "Suggestion: deploy reinforcement from standby units?"
Kieth: "They're all down! We're out of time!"
He glanced at the live feed—Chris in his Liger Zero, fighting desperately against Azazel; Cane locked in the sky duel with Astaroth; and Josh, charging toward Chris's position with his sword drawn.
Everything was crumbling.
Metatron: "Keith, remaining time for all active summons is six minutes. If the enemy maintains current pressure, we will suffer total collapse in nine."
Kieth clenched his teeth. "Then I guess it's time we even the odds."
He stood, aura sparking around him. "Metatron… prep for Godlink Mode."
Metatron: "Affirmative. Warning: deploying Godlink Mode will halve your lifespan temporarily."
Kieth: "I know. Just do it."
The sky above began to darken, lightning crackling in spirals as Kieth raised his arm. His summon link expanded—pulling energy from every still-functioning unit. The broken Zoids, battered Transformers, and dying Terminators all lifted their heads as glowing lines of code spread through their bodies.
They weren't retreating anymore. They were merging.
Across the battlefield, the remaining mechs fused into a colossal hybrid form—half mechanical, half ethereal—a towering titan brimming with divine light and metallic fury.
Metatron's voice echoed across the field:
"Summon fusion complete: Army Overlord, Omega Prime. Time limit—five minutes."
Kieth exhaled and smirked. "Then let's make those minutes count."
The shockwave from the explosion hadn't even faded when Cane's voice cut through the smoke, ragged but still alive.
Inside the Cosmic Black Barbatos Lupus Rex, warning lights flashed like dying stars. Panels hissed and sparked, half the cockpit shattered, and smoke filled the confined space. Cane's hand trembled on the control stick, his knuckles white.
[WARNING: Armor integrity 9%. Reactor temperature critical. Power output 15% and falling.]
"Still… not enough…" Cane muttered through clenched teeth. Sweat dripped down his jaw. His lungs burned. "Come on, you bastard… get up."
Barbatos twitched, servos whining. One leg gave out for a second before the Gundam forced itself upright, molten armor dripping from its frame. Across the burning horizon stood Astaroth, his demonic form towering—one horn shattered, his left wing torn clean off—but his grin was still cruel, sharp as ever.
"Persistent little insect," Astaroth growled, dragging his black greatsword through the dirt. "Do you even realize what you're fighting against?"
Cane spat blood onto the cockpit floor. "Yeah," he said, voice hoarse but steady. "A big ugly bastard who talks too much."
Astaroth laughed—a guttural, hellish sound that shook the air. Then he moved. The ground cracked beneath his charge, the sheer pressure of his presence making the sky tremble. His sword came down like a falling meteor.
Cane barely blocked it. Barbatos's arm shattered at the elbow, sparks spraying like fireworks. The impact hurled the Gundam backward into the ruins of a fortress wall.
BOOM!
Stone and metal exploded outward, swallowing Barbatos whole.
"Still breathing?" Astaroth hissed, walking toward the wreckage, sword raised high. "Then allow me to fix that—"
But his words were drowned out by a sound that didn't belong to their fight—
A roar.
Mechanical. Colossal. Like an entire army had screamed at once.
Both of them turned.
Far across the field, something massive rose from the smoke—Omega Prime, Kieth's fused summon. Its silhouette blotted out the sky, the combined might of the Zoids, Transformers, and Terminators merged into one godlike frame. Each step shook the ground. When it raised its arm, the clouds split apart from the energy radiating off its core.
It took a single swing.
The beam that followed carved through the battlefield like a divine guillotine—erasing an entire legion of demons in one shot. The blast wave reached Cane and Astaroth a moment later, the shock rattling the Gundam and tearing chunks of armor from the demon's body.
Cane stared, awe flickering across his eyes. "That's Kieth's doing…" he breathed.
"Impressive trick," Astaroth snarled, shielding his face from the light. "But it changes nothing!"
He lunged again—this time faster, his wings igniting with infernal energy. His sword came down in a blazing arc. Cane reacted instinctively, throwing Barbatos's tail forward. The Tail Blade coiled around Astaroth's sword, dragging it off course.
Then Cane hit the thrusters.
"Not today!" he shouted. Barbatos headbutted Astaroth with a bone-crunching crack, then fired all remaining thrusters at once—ramming the demon through several boulders before slamming him into the earth hard enough to make a crater.
Both warrior and demon were panting now. Barbatos's chest glowed from overheating, Astaroth's once-black armor glowing red from burns.
Metatron: "Cane! Reactor critical—collapse in sixty seconds!"
Cane: "Yeah? Then sixty's all I need."
He shoved the throttle to its limit. The cockpit lit up like a star about to go supernova.
Barbatos's body started to change—its black armor fracturing, revealing pulsing silver energy beneath, streaks of starlight running across its frame.
Astaroth rose, clutching his sword. "What trick is this—?"
Cane's eyes glowed faintly. His voice came calm, steady. "No trick. Just willpower."
He lifted Barbatos's head and aimed its horn at the demon. The Gundam roared—its voice shaking heaven and hell alike.
"Cosmic Breaker…"
The horn blazed. The ground cracked. Everything seemed to stop for a breath—then the world erupted.
A beam of concentrated cosmic light fired point-blank, engulfing Astaroth completely. His roar turned into a scream that was swallowed by the explosion. The shockwave rippled for miles, lighting the sky like dawn breaking through the apocalypse.
When the light faded, Barbatos was kneeling, smoking, half its body gone. The reactor flickered weakly.
Cane slumped forward, barely conscious. "Heh… guess I got him…"
Metatron's voice came through the static, soft but urgent.
"Cane, life signs are unstable. You need extraction immediately."
"Tell Kieth…" Cane whispered, his eyelids heavy. "We ain't losing… not today…"
His screen flickered, showing Omega Prime in the distance tearing through enemy ranks—unstoppable, radiant, godlike.
Cane smiled faintly. "Damn… that's one hell of a view."
Then the screen went black.
To be continue...
