The air between them didn’t just tense; it ignited. For three heartbeats, the entire hall held its breath, a vacuum of silence where the only sound was the distant crackle of torches.

Then, Rex exploded forward.

He didn’t rush; he launched. His first strike was a piston-like straight right aimed directly at Aurelia’s sternum, designed to wind her before she could react.

Aurelia didn’t retreat. Instead, she pivoted on the ball of her left foot, her body spinning with the grace of a dancer and the lethal intent of a viper.

Rex’s fist cut through empty air with a vicious whoosh, and in that same microsecond, Aurelia unleashed a roundhouse kick aimed at his temple.

WHIP CRACK.

Rex ducked, the wind of her shin passing inches above his scalp. He immediately drove his shoulder into her midsection, attempting to drive her backward, but Aurelia was like water; she flowed around his impact.

She grabbed his extended arm, used his momentum against him, and attempted to twist his elbow into a break.

GRIND.

Rex roared, a sound of pure animal defiance, as he braced his forearm against his own bicep to prevent the joint from snapping. He twisted his hips violently, breaking her grip, and countered with a devastating knee strike aimed at her ribs.

THUD.

Aurelia caught the knee with both palms, the impact sending a visible shockwave through her shoulders. Her feet skidded across the hardwood, leaving faint scorch marks from the sheer friction.

"Not bad," she hissed through gritted teeth, her eyes blazing. "But you’re telegraphing your intent with that anger, Rex!"

She lunged. This wasn’t a probe; it was a barrage.

A left hook, a spinning elbow, and a lightning-fast jab that forced Rex into a desperate defensive shell. Rex retreated two steps, his forearms raised in a cross block.

CLACK CLACK CLACK.

Each impact sounded like two sledgehammers colliding. His bones vibrated with each blow, the sting of her precision strikes seeping through his guard.

He saw her opening, a split-second hesitation after her jab, and he seized it. Rex stepped inside her guard, abandoning defense for raw, crushing offense.

He delivered a three-punch combination: a left uppercut that snapped her head back, a right hook that caught her jaw, and a brutal left cross to the solar plexus.

CRACK. THWACK. OOF.

Aurelia gasped as the air was punched from her lungs, but she refused to collapse. Instead, she grabbed Rex’s collar, pulling him closer as she drove her forehead into his nose with a sickening CRUNCH.

Blood erupted from Rex’s nose, spraying across both their faces. The pain was white hot, a searing lightning bolt that momentarily clouded his vision.

But the pain only served to sharpen his focus. The world narrowed down to the taste of copper in his mouth and the heat of Aurelia’s body pressed against his.

They entered a state of pure, unadulterated violence, a close-quarters brawl where technique blurred into primal instinct. They traded blows with terrifying frequency.

Rex landed a heavy kick to her thigh that sounded like a wet branch breaking; Aurelia responded with a palm strike to his ear that sent his equilibrium spinning.

BAM. WHACK. CRUNCH.

Rex grabbed her wrist, attempting to execute a bone-breaking twist, but Aurelia dropped her weight instantly, becoming impossibly heavy.

She drove her forehead into his chest and spun, catching Rex in a leg sweep that sent him crashing to one knee. Before he could recover, she was on him, her fists raining down like hammer blows.

THUD. THUD. THUD.

Rex rolled backward, the floorboards splintering under the force of his escape. He came up swinging, a wild, sweeping kick that caught her mid-torso.

Aurelia flew backward several feet, her boots skidding across the blood-slicked floor, but she landed in a crouch, already coiled for the next assault.

Both were drenched in sweat and crimson. Their breathing was no longer human; it was the ragged, desperate gasping of two apex predators fighting for dominance.

Blood dripped from Rex’s chin onto the floor, mixing with the stains already there. Aurelia’s lip was split badly, a steady stream of red running down her chin, but her eyes remained fixed on him with terrifying clarity.

"Is this..." Aurelia panted, wiping blood from her eye with the back of her hand, "...is this the ’conquest’ you promised?"

Rex wiped his nose, smearing more blood across his cheek. His muscles screamed, and his ribs felt like they were grinding together, but a savage grin split his face.

"We haven’t even started breaking things yet, Aurelia."

He charged again, not with a technique, but with the unstoppable force of a landslide, his fists clenched and his eyes locked on hers. The clash that followed was louder, more brutal, and more desperate than anything the Nightwing household had witnessed in centuries.

The collision between them sounded less like human combat and more like two armored vehicles crashing at full speed. When Rex met Aurelia’s charge, the force of their impact sent a shockwave through the training floor that made the nearby guards stumble.

Rex threw a devastating haymaker, a right hook that carried the weight of his entire body behind it. But Aurelia didn’t just dodge; she danced through the danger zone.

She dipped her shoulder beneath his arm, the motion so fluid it seemed almost supernatural, and as she passed inside his guard, she unleashed a devastating combo that demonstrated why she was the matriarch of this bloodline.

WHIP THUD CRACK!

First came a lightning-fast left palm strike to Rex’s diaphragm, forcing the air from his lungs in a wet wheeze. Before he could recover his breath, she spun on her heel, converting the momentum into a vicious elbow strike that caught Rex squarely across the cheekbone.

CRACK.

The sound of cartilage protesting echoed off the stone walls. Without pausing for even a heartbeat, Aurelia followed through with a snap kick to his kneecap, her shin connecting with the joint with the force of a breaking sledgehammer.

THWACK.

Rex grunted as his leg buckled, but his training took over. Instead of falling, he used the pain as fuel.

As Aurelia pulled back to reset, Rex twisted his torso mid-collapse, driving an uppercut upward that caught her under the chin.

BOOM.

Aurelia’s head snapped back violently, blood spraying from her mouth as her teeth collided. She stumbled backward, but Rex was already on her.

He lunged forward like a wounded bull, his fists becoming a blur of relentless aggression. He threw a left jab to her eyes to obscure her vision, followed immediately by a thunderous right cross to her ribs.

PUFF. CRUNCH.

Aurelia gasped as a rib visibly shifted under the impact, but her fury only intensified.

"Is that all?" she roared through the blood.

She met his aggression with a counter combo that left the onlookers speechless. As Rex swung for a finishing blow, Aurelia caught his wrist with both hands, twisting her body sideways to redirect his power into the floor.

While he was off balance, she drove two consecutive knee strikes into his solar plexus, THUD THUD, each one more precise than the last, designed to collapse his diaphragm.

Rex staggered, his vision swimming with dark spots, but as she moved in to capitalize, he threw his forehead forward in a brutal headbutt.

CRUNCH.

The sound of their skulls colliding was sickening. Both fighters recoiled, blood streaming down their foreheads. Rex’s nose was a ruin of broken cartilage, and Aurelia’s left eye began to swell shut instantly.

They stood three feet apart for a moment, both swaying, their breathing coming in ragged, desperate gasps that sounded like tearing cloth.

"You... fight like a demon," Aurelia spat, wiping a thick smear of blood from her lips.

Her voice was thick, her composure shattered, replaced by something far more dangerous: genuine bloodlust.

"And you..." Rex growled, spitting a glob of crimson onto the floor, "...fight like you were born from a massacre."

Rex charged again, but this time it was different. He wasn’t just throwing strikes; he was weaving them together.

He feinted a high kick, drawing Aurelia’s guard up, then immediately dropped low, driving a vicious leg sweep that caught her ankles. As she stumbled, he came up with a rising elbow aimed at her throat.

WHOOSH.

Aurelia twisted her neck at the last millisecond, the elbow grazing her carotid artery. She retaliated with a spinning back fist that caught Rex across the temple.

WHACK.

His head snapped sideways, blood spurting from a fresh gash on his scalp.

The fight descended into a beautiful, horrifying chaos. They became two storms colliding in the center of the hall.

Rex would land a crushing blow to her ribs (THUD), and Aurelia would respond with a flurry of three precise punches to his kidney and liver (BAM BAM BAM), forcing him to double over.

When he would grab her, attempting to crush her throat with his forearm, she would drive her thumbs into his pressure points, seeking to paralyze his grip.

GRIND. SNAP. THUD.

The floor beneath them was no longer wood; it was a slick, crimson mire of sweat and blood. Every time they landed a solid hit, the sound reverberated through the room like a gunshot.

The elite unit watched in stunned silence, recognizing that they weren’t watching a spar; they were watching two gods tearing each other apart to see who would claim the throne.

Rex’s knuckles were split open, dripping blood onto Aurelia’s torn training gear. Aurelia’s breathing was a series of broken sobs of exertion, her ribs bruised to the bone.

Yet neither would yield. Each time one stumbled, the other would press the advantage with renewed ferocity, their movements becoming more primal, less technical, and infinitely more deadly.
