The sharp crack of knuckle joints filled the prep room as Mona flexed her hands, watching her reflection mirror the motion in Da Vinci’s gleaming titanium claws. The Brain Port tingled at the base of her skull, a familiar electric kiss that signified their perfect calibration. One mind, two bodies: fighter and machine, sister and weapon.
“Remember what we discussed,” Sal’s gravelly voice interrupted her concentration. “Your opponent is strong, but that Graces tank of his consumes power cells at an incredible rate. If you outlast him, you will win.”
Mona nodded, rolling her shoulders as Da Vinci’s lean frame mirrored the movement behind her, casting an ethereal blue shadow across the scuffed concrete floor. The mechanical fighter stood three times her height, but where other units were built like brick walls, good old Vi was all lethal agility— a predator in chrome and cyan. Oval weapon plates adorned the back of her forearms, currently dormant but ready to spring to life at a moment's thought. The articulated tail extension, tipped with titanium spikes, swayed with perfect balance, each movement precise and purposeful. It was a true testament to technological innovation and the underground fight scene’s endless appetite for spectacle. But Vi was more than just metal and circuits — she was an extension of Mona’s rage, her need for vindication.
“I’ve run the simulations a hundred times,” Mona muttered, her eyes fixed on Vi’s reflection as diagnostic readouts scrolled across her neural feed. The Mech’s lightweight carbon-fiber frame was their secret weapon; most pilots couldn’t handle the neural load of such a responsive unit, but Mona had spent years honing her connection to a razor’s edge. “Shredder’s fool thinks he can pummel us in the first round. He has no idea what we’ve built.”
Sal’s weathered hands found her shoulders, steadying her with the same firm gentleness he had shown since the day he took her in. “This is not about the simulations anymore, Y’Gythgba. This is about what’s in here.” He tapped her temple. “And what’s in here.” His finger moved to her chest, right above her heart.
The bitter taste of memory rose in her throat — her last professional fight, before the accident. Before they said she would never box again. Before her family was lost.
“I remember everything,” Mona whispered, and Vi’s talons curled into fists with an ominous whir of servos. “Every second of lying in that hospital bed, trying to remember how to make my own hands work.”
“Good,” Sal said, his voice hard. “Use it. But do not let it use you.” He moved to Vi’s maintenance panel, checking connections with practiced efficiency. “Your anger is the fuel, not the engine. You lose control out there, you lose everything.”
Mona closed her eyes, feeling the smooth flow of data between her mind and Vi’s systems. They had spent two years perfecting this synchronization, pushing the boundaries of what was possible with neural integration. Most pilots treated their Mechs like puppets, but Vi was different. Vi was a dance partner in a ballet of destruction, light enough to pirouette through enemy defenses, and fast enough to deliver three strikes before their opponents could process the first. Vi was her other self, born from countless nights of determined coding and calibration.
The five-minute warning buzzer startled her, sending a cascade of feedback through the neural link that caused Vi’s status lights to flicker. Sal pretended not to notice as he helped her into the pilot exoskeleton, checking each seal with methodical precision.
“You possess something the Shredder will never comprehend,” he said, adjusting the spinal interface. “You understand what it means to lose everything and to rebuild yourself from nothing. That hardware he’s using,” he gestured toward the arena door, “is merely a fancy toy to him, each fighter replaceable. But Vi? Vi represents your second chance. Your redemption.”
Mona felt the familiar pre-fight tremors starting in her hands, but Vi remained steady, a fortress of gleaming metal and purpose. Through their shared vision, she could see that all the diagnostics were reading green, power levels were optimal, and response times were faster than they had ever been in training.
“When we get out there,” she said, her voice barely above a whisper, “I want him to see me. Really see me. Before Vi tears that overpriced scrap heap of his apart, I want Shredder, Dregg, and the Triceratons to look me in the eye and remember exactly who they tried to destroy.”
Sal’s reflection appeared beside hers in Vi’s polished chest plate, his eyes dark with concern and pride. “Just remember what I taught you. Honor—”
“—is victory. I understand, Commander ,” Mona finished, managing a slight smile. It was their ritual, their private joke. She felt the neural sync pulse stronger, feeding off her rising adrenaline.
The final buzzer sounded, and the arena door began to rise with a mechanical groan. The roar of the crowd filtered through, a wall of sound that made her skin prickle. Somewhere out there, Raphael Hamato was waiting with the famous Graces, likely wearing some smug smile that Mona would be keen to wipe off his face.
“It is time,” Sal said softly, stepping back as Vi’s cockpit opened with a pneumatic hiss.
Mona took one last look in the mirror. Her reflection stared back at her, all lean muscle and burning eyes. Above her, Vi’s massive bruise-blue frame hummed with potential energy, ready to transform thought into devastating action. They were more than pilot and machine, more than a weapon system. They were justice incarnate, vengeance given form in steel and synapse.
“Let’s show them what fighting really means,” she whispered. Mona closed her eyes and began her climb into the cockpit.
wires and veins. bones and chassis.
ears and mesh. eyes and coordinates.
muscle and metal. skin and shell.
voice and soundbox. clothes and armor.
fingers and talons. READY.
Vi stepped forward.
The crowd went wild . They always did.
The arena lights hit Vi’s cyan plating like celestial spotlights as Mona guided them through the entrance. Across the reinforced cage, Graces emerged — a towering hulk of dark steel that made the ground shudder with each step. Steam vented from its joints, and beneath its armor plating, Mona could see the telltale red glow of its molten defense system.
“How cocky,” Sal’s voice crackled through her comms. “Look at those power readings. It’s operating at a high level right from the outset.”
Mona’s fingers flexed inside the neural interface pods, feeling Vi’s responsive tremor. The crowd’s roar became a distant hum as she sank deeper into the sync, letting Vi’s sensor data flood her consciousness. Temperature readings, power distributions, structural weak points — all of it flowing through her mind like a digital river.
The bell rang.
Graces charged like an avalanche of metal and fire, its armor beginning to glow. The crowd surged to their feet as Vi darted sideways, letting their opponent’s massive fist crater the wall behind them. The heat signature alone made Mona’s environmental alerts scream.
“That’s right,” she murmured, directing Vi into a series of rapid jabs at Graces’ knee joints. “Burn yourself out, you overgrown monster.”
The larger Mech’s retaliatory swing came faster than she’d anticipated. Vi’s spiked tail whipped up instinctively, deflecting some of the blow, but the impact still sent them sliding across the cage floor. Warning indicators flashed around her vision — the surface temperature of the contact point had nearly melted through its outer plating.
The crowd was chanting something, but Mona tuned them out, focused on the bout. Vi’s weapon plates hummed to life as they circled Graces, looking for openings. Raphael was good, she had to give him that. Even with all that bulk, he kept Graces between Vi and a corner to cool down, protecting his future lifeline.
“Watch your left!” Sal’s warning came just as Graces unleashed a devastating combination. Vi’s superior agility turned what should have been crushing blows into glancing impacts, but each touch of that molten armor left scorching marks on their cyan plating.
Three minutes in, and Mona could see Graces’ power consumption spiking. But Vi had taken damage too — its left arm’s response time was degrading from heat exposure. The crowd’s electricity built with each exchange, their bloodlust a physical presence in the cage.
“Getting tired, sweetheart?” Raphael’s voice cut through the general channel, dripping with condescension. “That pretty lightshow of yours can’t dance forever.”
Mona didn’t respond, but Vi’s tail lashed the air in irritation. She knew what he was doing — trying to bait her into a mistake. Instead, she focused on their breathing exercises, keeping her heart rate steady as they waited for their moment.
That moment came seven minutes in.
Graces’ molten armor began to flicker, its power cells draining faster than its cooling systems could compensate. Vi’s sensors caught the millisecond delay in its movements — the tell-tale hesitation of a Mech preparing to pause for recharge.
The crowd saw it too. Their fever pitch rose as Graces began backing toward a corner to recharge, still throwing devastating but increasingly slower punches to keep Vi at bay. Heat waves distorted the air between them, creating a shimmer of potential violence.
“End it,” Sal’s voice was steel in her ear. “End it now.”
Time seemed to slow as Mona initiated their attack sequence. Each movement felt like flowing through honey, yet her neural processors registered everything in hyperfocus. Vi’s tail extended to its full length, each segment unlocking with precise clicks that she felt in her own spine.
This is for every night I spent relearning how to hold myself up , she thought, as they burst forward.
Graces swung wide — she could see the desperation in the arc of its punch, the way its molten armor flickered like a dying sun. They slid under the blow in a dance they’d practiced a thousand times, and Mona felt their paint bubble from the heat.
This is for every doctor who said I’d never fight again . The world contracted to this moment, this breath, this strike.
Vi’s tail moved with amphibian haste, each spike catching the arena lights as it whipped upward. Mona could feel the exact moment they found purchase — the sweet spot between armor plates, where Graces’ compromised defenses were weakest. The impact traveled through their neural link like a tuning fork struck against steel, and she savored every microsecond.
This is for me.
The larger Mech’s own weight became its undoing. Vi’s lighter frame coiled like a spring, and Mona poured every ounce of their shared strength into the next motion. The tail’s grip held true as they pulled, transforming Graces’ bulk into momentum. She watched in exquisite detail as their opponent’s feet left the ground — a ballet of physics and vengeance.
The impact when Graces hit the cage wall didn't just ring; it sang. Metal screamed against metal in a symphony of destruction that Mona felt in her teeth. Warning lights cascaded across her neural feed, but she dismissed them with practiced thoughts. Not yet. We’re not done yet.
Vi’s weapon plates hummed to life, their oval surfaces splitting to reveal the electromagnetic generators beneath. Time stretched like taffy as they struck again, each blow precisely targeted where their tail had breached Graces’ defenses. Mona could see the energy pulses traveling through the larger Mech’s systems, whirling like lightning through its compromised circuits.
This is for my family!
System failure warnings flashed crimson in her vision — Vi’s circuits were screaming from the sustained proximity to Graces’ heat. But Mona pushed through it all, drinking in every detail: The way sparks scattered like falling stars from each impact point, the subtle ripple of failing hydraulics beneath Graces’ armor, the almost beautiful way its molten defense systems flickered and died.
“Stay down,” she hissed, both prayer and command. Vi’s tail became a blur of cyan and silver, each strike finding its mark with surgical precision. She felt the resistance lessen with each hit, felt the bigger Mech’s systems failing beneath their onslaught. This is what vindication feels like . “Just stay down.”
The referee’s call came like a voice from another world, barely penetrating the crystal-clear focus of their shared consciousness. Vi’s systems were redlining, their once-pristine cyan plating now a masterpiece of battle damage and scorch marks. But they were standing. They had won.
The crowd’s reaction hit her then — a wall of sound and emotion that threatened to overwhelm her neural sync. She saw faces contorted in victory and defeat as money changed hands, and somewhere in the chaos, Sal’s proud smile as he approached the cage.
“Not bad for a pretty lightshow,” she broadcast on the general channel, finally allowing herself a moment of satisfied vengeance as Graces’ emergency systems engaged, flooding the mighty Mech with coolant.
Through their shared vision, she watched Raph's team rush to his aid, their movements frantic as they tried to safely extract him from his overheated cockpit. Part of her wanted to savor his defeat more, but Vi’s tail simply curled in quiet satisfaction. They had proven themselves with skill and strategy, not cruelty.
“Time to get you patched up,” Sal’s voice was warm with pride as maintenance crews approached. “Both of you.”
Mona nodded, finally allowing herself to feel the neural feedback from Vi’s damage. They hurt everywhere, but it was a good hurt. A victorious hurt. As they made their way toward the exit, Vi’s steps perfectly in sync with her own despite their injuries, she realized she was smiling.
They had won .
The maintenance bay’s industrial fans did little to dispel the lingering heat from the arena. Mona traced her fingers along Vi’s cooling plates, feeling phantom warmth through the neural echo that always lasted hours after a sync. They’d earned their scars today — both of them. The repair crew had already started preliminary work, but she needed a moment away from the chaos, away from Sal’s proud celebrations and the sponsors’ eager pitches.
She found herself wandering the facility’s outer walkway, where sodium lights painted everything in shades of amber and shadow. The night air felt clean in her lungs, washing away the metallic taste of victory. Above, stars peeked through gaps in the city’s light pollution, distant and indifferent to the battles fought beneath them.
“That was a cheap shot with the tail.”
The voice made her spine stiffen. Raph emerged from the darkness near the loading dock, his pilot suit still showing signs of heat damage around the edges. His jaw was set tight, shoulders squared despite the obvious pain he was in. The bruises from the neural collectors traced angry patterns up his neck, disappearing beneath his collar.
“Your definition of ‘cheap’ seems to correlate with’'effective,’”Mona stated, her voice clinically detached. She maintained her position at the railing, posture perfect, calculated.
His eyes flashed, but something else flickered there too — something he quickly buried beneath a scowl. “You got lucky. Caught me at the end of a power cycle.”
“Lucky?” She examined her neural port’s cooling pad with practiced indifference. “The data suggests otherwise. Your power management was inefficient from the start.”
Raph took a step forward, then caught himself. His fists clenched and unclenched at his sides. “Two weeks,” he said, voice rough. “Give me two weeks to get Graces back up. We’ll see how well that speed holds up against someone who knows what's coming.”
“Your defense systems were noteworthy,” she acknowledged, her tone remaining professional, distant. “Though the execution lacked care. The armor’s heat distribution was… unstable.”
The compliment wrapped in criticism seemed to throw him off balance. “Yeah, well…” He rubbed his neck, wincing, then caught himself showing weakness. “Could have melted that pretty paint job clean off if you’d stayed still long enough.”
“Pretty?” Her eyebrow arches.
Color crept up his neck, barely visible beneath the bruising. “You know what I mean. All that flashy lightweight garbage. Real Mechs have substance.”
“Real Mechs, or real pilots?” She stepped forward, movements measured, nothing wasted. “Your left-side telegraph obviously presents a significant vulnerability. I could have timed it without Vi’s sensors.”
The technical critique landed like a physical blow. He blinked, anger warring with respect and something far more complicated. “You… you were reading my combinations?”
“Every single one.” Her response was immediate. “Your attack patterns were predictable. Some of us had to learn to fight before we learned to pilot.”
“I…” He started strong but faltered, caught between what he’d come to say and what he was actually feeling. “Graces will be ready in two weeks. No power cycling issues next time. No holding back.”
“Holding back?” Now she did smile, watching him struggle not to respond to it. “Is that what you call that desperate flailing?”
“I wasn’t desperate!” he growled, but there was heat beneath the anger. “Next time—”
“Next time,” she cut him off, taking another step closer. Close enough to see the flecks of green in his darkened eyes, to smell the ozone and metal that clung to all veteran pilots. “Try leading with your right.”
The facility’s warning lights began their end-of-shift rotation, painting them alternately in red and shadow. For a moment, neither moved, caught in the gravity of unspoken possibilities.
“Two weeks,” he finally said, voice rough. “Whether it’s in Graces or… somewhere else. Your choice.”
“Two weeks,” Mona agreed. She turned away first, feeling his gaze follow her movement. “Though I suggest reviewing your power consumption metrics before attempting another engagement. Try not to blow any more power cells before then. I would hate for you to have another excuse when I win.”
“When you–” He cut himself off with a frustrated sound that was almost a laugh. “Just be ready.”
“Punctuality is a given.” She glanced back over her shoulder, savoring that evident look of energy on his features. “Do attempt to present more of a challenge next time.”
She left him standing there in the sodium glow, the weight of possibilities hanging between them like charged particles before a storm. Above, the stars continued their ancient dance, witnessing all possible futures without judgment. And somewhere in the maintenance bay, Vi’s tail twitched with a phantom sensation, ready for whatever challenge came next — in or out of the cage.
