The instant the Nitro Capsule's flow fused with Karl's flaming Rider Frame, the battlefield erupted in a storm of blue plasma and Royal Azure fire. Every fragment of molten rock trembled beneath the shockwave, shards of debris spinning wildly as if caught in a tornado. Karl hovered for a heartbeat, weightless, suspended in a cocoon of incandescent energy.
Then, with a violent pulse, the injector retracted, and Karl's body shifted, torque currents realigning at impossible speed. His nanites reshaped in real time: sleek armor plating formed along his shoulders and thighs, reinforced thrusters ignited along his spine, railgun-like arm cannons glimmered with unstable energy, and his visor extended into a sharp, predatory V-shaped HUD. Every movement of his floating gears, every rotation of his joints, radiated controlled, deadly force. The flames engulfing him now danced in perfect synchronization with the Nitro energy coursing through his body—a living, writhing storm of power.
Agnes' voice filled his mind, now chaotic, trembling with ecstatic energy. "K-Karl… it's… it's overflowing… every pulse… I can feel… EVERYTHING… IT'S MINE… AND YOURS—!"
Karl's hands clenched, igniting plasma vents along his legs. His Rider Frame hummed with energy, torque currents thrumming like a war drum. "Overburn Jet… NITRO DRIVE… ONLINE!" His voice roared over the battlefield, the heat of his flames scorching the very air.
The Sentinel froze, its sapphire core flickering in recognition. Every ember it had sown into Karl was now dwarfed by the sheer magnitude of the Overburn Jet transformation. The Titan pivoted, attempting to raise its flamethrower arms—but Karl moved first.
With a sudden burst of thruster power, he launched into a blinding blue streak, micro-rails compressing beneath him as floating gears whirled at maximum RPM. He pivoted midair, dodging sapphire plasma bursts with surgical precision, and struck the Sentinel's right arm with reinforced fists. The impact erupted into sparks and flame, melting seams of reinforced armor in seconds.
The Sentinel reeled, stumbling back, clearly realizing the gulf of power had widened. Karl's eyes glowed behind his V-shaped visor, every movement now a blur. Each kick, each punch, each micro-projectile hit with devastating precision, tearing through the Sentinel's mechanical limbs.
The gap remained massive. Karl pivoted, thrusters igniting in tandem with his arm cannons. Plasma rounds tore through the Sentinel's armour
each strike precise and overwhelming. Sparks and molten streaks erupted across the battlefield. The Sentinel's adaptive flames flared violently with each hit, but the Nitro energy in Karl's body countered every defense, allowing him to slice through armor faster than it could regenerate.
"Torque… compression… velocity… everything synced…" Karl muttered, executing a dizzying sequence of rotations. His floating gears ricocheted debris with surgical accuracy, micro-rails launched him around the Titan's limbs, and reinforced fists shattered flaming armor segments as if they were glass.
The Sentinel roared, sapphire flames surging higher, attempting to counter with flamethrower strikes and plasma bursts. For a brief moment, the power gap narrowed—the adaptive flame pushed Karl's attacks to their limits, forcing him to calculate every move precisely. But the Overburn Jet Frame was beyond conventional limits. Every kick, every punch, every micro-projectile carried kinetic force amplified by the Nitro Capsule, every thruster burst accelerated him beyond the Titan's predictive systems.
Karl's fist slammed into the Sentinel's chest, breaking through its armor. The impact produced a shockwave that rippled across molten rock and steel, throwing debris into the air. Sparks cascaded down like shooting stars, and the Sentinel staggered backward, struggling to maintain equilibrium.
The Sentinel responded, attempting a sweeping flamethrower barrage, but Karl twisted midair, floating gears acting like slicing barriers. He accelerated, firing twin railgun cannons from his forearms. Each plasma shot drilled into the it's limbs and core, tearing apart armor in milliseconds.
Sentinel's core pulsed violently, sapphire flames exploding outward in a desperate attempt to overwhelm Karl. Flames raced across the battlefield, scorching molten debris into vapor. But Karl twisted through the inferno, using torque-enhanced spins to deflect the worst of it. Every strike he delivered tore away more armor, shredded more limbs, and forced the Sentinel into retreat.
The battlefield had become a storm of blue and royal azure flames, plasma streaks, and molten rock. Karl was the eye of the storm, a perfect storm of heat, energy, and torque. Even with its adaptive flame armor, the Sentinel could not match his speed or precision. Its sapphire core pulsed furiously, but every pulse fed Karl's momentum, every defensive adjustment the Sentinel made was anticipated and countered.
Finally, Karl executed a devastating aerial flip, thrusters igniting in unison with a plasma surge. His arm cannons discharged, micro-projectiles embedded, and reinforced fists struck with full Nitro compression. The Sentinel's flaming armor shattered like brittle crystal, pieces evaporating into smoke and sparks. The Sentinel collapsed to one knee, flames sputtering as its adaptive defenses struggled to maintain coherence.
Karl hovered above, visor gleaming, floating gears spinning madly, flames licking along his frame but fully under his control. He exhaled, heart pounding. The Overburn Nitro Jet Frame burned brighter than ever, his Nitro energy stabilizing every torque current, every floating gear, every nanite overlay.
"…Dominant…" he muttered through clenched teeth. "…Completely…"
The Sentinel struggled to rise, flames still coating its limbs in an attempt to recover. But Karl's acceleration, precision, and sheer destructive power now made the Titan's attempts feeble in comparison. The power gap remained massive. Even with adaptive flame armor, it was fighting a force it could no longer predict, a warrior now fused with fire, plasma, and Nitro energy.
Karl pivoted again, floating gears spinning, thrusters firing, plasma bursts ricocheting off molten debris. The Overburn Jet Frame radiated energy, heat, and motion—an unstoppable storm.
"Agnes… the gap…" Karl muttered, almost in awe, feeling the Nitro energy coursing through him. "It's… theirs now…"
"Yes… Karl," she whispered, voice trembling through the interface, still stabilizing fragments of Vythra. "…You are… unstoppable… and the flames… they're yours to command…"
Karl's eyes glowed behind the visor, floating gears spinning in perfect synchronization with the roaring thrusters. Flames licked across his frame, controlled, precise, alive—but now entirely under his will. The Sentinel tried to recover, but every move was anticipated, every strike blocked, countered, and returned with devastating force. The power gap, though partially mitigated by adaptive flames, remained overwhelmingly in Karl's favor.
He hovered above the battlefield, arms crossed, flares of Nitro energy and Royal Azure fire radiating outward. The Sentinel, exhausted, staggered, and burning, barely maintained its footing. Karl had become more than a Rider Frame; he had become a living storm, a dominator of fire, speed, and plasma.
And the battlefield itself trembled at his presence.
