The corridor opened abruptly into a space so vast that Sophia's breath stalled in her chest.
It wasn't a room. It was a battlefield carved inside DNA itself.
A colossal circular arena stretched outward in layered tiers, each level ringed with railings forged from dark chromatic alloys. Thousands—no, tens of thousands—of figures stood in disciplined formation across those levels. Mk-2 units closest to the arena floor, their frames lean and utilitarian. Above them, Mk-3s with reinforced skeletal plating and brighter reactors. Higher still, Mk-4s—sleek, elegant, terrifyingly refined, male and female indistinguishable in perfection, all clad in DNA obsidian attire.
Far below, partially obscured by structural ribs and anti-gravity fields, stood something else entirely.
A Megatron.
Giant didn't begin to describe it. Its silhouette alone warped perspective, reactor burning like a miniature sun behind layers of armored geometry. It stood motionless, yet Sophia felt as if it were watching everything at once.
Her heart began to pound.
This isn't an evaluation, her mind whispered. This is a judgment.
Sophia's shoulders stiffened. Her palms were damp inside her gloves. She forced herself not to step back.
Dr. F moved forward.
Casually.
He stepped past the edge of the platform—and did not fall.
Sophia's eyes widened despite herself as his foot settled on empty air, invisible force shaping itself beneath him. He walked upward as if ascending an unseen staircase, white coat fluttering slightly, hands still folded behind his back. Gravity bent to his will without sound, without resistance.
Of course, she thought bitterly. Why would physics apply to him?
He rose toward an elevated evaluation dock—an isolated platform suspended above the arena like a throne that pretended not to be one.
Waiting there was another figure.
At first glance, Sophia thought it was Dr. F reflected in a mirror.
White coat. Same posture. Same stillness.
But then she saw the differences.
The eyes were too precise. Too luminous. The movements—when the android shifted its weight—were flawless in a way no human body ever truly was. Its face was calm, expression neutral, skin indistinguishable from living flesh, reactor faintly visible beneath the sternum like a restrained star.
An android in a white coat…
So he's not alone.
Below, the two Terminator-class destroyers separated from them, descending toward the lower levels with seismic steps that made the arena hum. The ranks of androids parted instinctively to let them pass.
Then the floor beneath Sophia's boots vibrated.
She gasped as the platform she stood on disengaged silently, lifting her from the edge and sliding her forward. Smooth. Unstoppable. It carried her out over the arena, suspending her above the center like a displayed artifact.
Her stomach lurched.
The battlefield rotated slowly around her, layers of spectators rising into her peripheral vision. Thousands of eyes—optical sensors, artificial pupils, glowing irises—locked onto her at once.
She was alone.
So this is how it feels, she thought, throat tight. To be seen by a world that doesn't care if you break.
The platform stopped.
Sophia stood at the exact center of the battlefield.
Above her, Dr. F looked down—not from arrogance, but from position. The android in the white coat stood beside him, hands folded, observing silently.
Dr. F's voice carried effortlessly, amplified not by speakers but by the arena itself.
"Agent Sophia Watson," he said, calm and precise. "You stand before DNA's evaluation field."
The words echoed—not loud, but absolute.
Sophia swallowed, lifting her chin. Her heart was racing, but her spine straightened instinctively, the old discipline surfacing through the fear.
I am still S-rank, she reminded herself. Even if they stripped everything else away.
Dr. F continued, eyes unreadable. "This field does not measure strength alone. It measures compatibility. Adaptation. Psychological resilience. Capacity for evolution."
The android beside him turned its head slightly, gaze fixing on Sophia with clinical interest.
Dr. F added, almost thoughtfully, "And survival."
Sophia's breath slowed. She forced herself to speak, her voice carrying upward.
"So," she said, "do I fight… or do I prove something?"
A pause.
Dr. F regarded her for a long moment.
Then, quietly, "That," he replied, "depends entirely on what you choose to show us."
The battlefield lights shifted.
Energy lines ignited across the arena floor, tracing complex geometric patterns beneath Sophia's feet. Far below, the Megatron's reactor flared once—slow, deliberate.
Sophia felt it then.
Not fear.
Expectation.
And somewhere deep inside her, beneath exhaustion and doubt and unwanted affection, something sharp and defiant stirred.
Fine, she thought.
If this world wants to judge me… it will have to watch me stand.
The air above the arena shimmered.
A massive holographic interface unfolded across the sky of the battlefield, translucent panes of light rotating and locking into place with surgical precision. Symbols cascaded downward in vertical streams before stabilizing into structured data columns. The sheer scale of it dwarfed Sophia, making her feel like a single variable inside an equation far larger than herself.
Dr. F's voice cut through the hum, steady and unmistakably in control.
"Evaluation parameters will now be displayed."
The screen brightened.
One by one, categories materialized in bold, sharp lettering—each word accompanied by shifting sub-metrics, numerical ranges, and fluctuating probability curves.
DESTRUCTION LEVEL
ADAPTABILITY
SURVIVAL RATE
ACCURACY
Sophia's eyes traced the list, her throat tightening.
So that's how they reduce a person, she thought. Four words and a percentage.
Dr. F continued, his tone neutral, as if he were explaining laboratory procedures rather than the framework of her fate.
"You will engage in sequential combat trials," he said. "Each tier calibrated to isolate specific attributes."
The interface shifted again.
Below the categories, silhouettes appeared—humanoid outlines at first, then increasingly complex forms.
PHASE I — MK-2 UNITS
PHASE II — MK-3 UNITS
PHASE III — MK-4 UNITS
PHASE IV — CONDITIONAL
Sophia frowned slightly.
"Conditional?" she repeated, unable to stop herself.
Dr. F glanced at her, just briefly.
"That phase activates only if earlier metrics exceed expectation," he said. "Or fall dangerously below."
That didn't answer anything—and somehow answered everything.
Sophia exhaled slowly, steadying herself. Start simple. Don't think about Mk-4 yet. One step.
"So," she said, forcing a thin edge of calm into her voice, "I fight my way up the food chain."
"Incorrect," Dr. F replied without hesitation.
She looked up sharply.
"You adapt your way up," he corrected. "If you attempt to overpower every unit, you will fail before Mk-3."
Her jaw tightened. He wasn't taunting her. He was instructing her.
The android in the white coat moved then, fingers dancing through the air. Additional data flared to life—weapon restrictions, environmental modifiers, regeneration dampeners, time-to-failure graphs.
Sophia felt her pulse quicken.
They've thought of everything.
Dr. F went on, his voice almost conversational. "Mk-2 units will test your baseline reaction speed and accuracy. Their behavior is predictable. Their errors are intentional."
Sophia raised an eyebrow. "Training dummies."
"Disposable data points," he corrected calmly.
Her stomach twisted—but she didn't argue.
"Mк-3 units," he continued, "will actively learn from your tactics. They will adapt within three engagement cycles. Emotional miscalculations will be exploited."
Sophia swallowed.
That's where people die.
"And Mk-4?" she asked quietly.
Dr. F paused.
Just long enough for the arena to feel colder.
"Mк-4 units will not fight you," he said at last.
Sophia's eyes widened slightly. "Then what will they do?"
"They will hunt you."
Silence rippled through the arena.
Sophia forced herself to breathe, staring up at him. Of course. Of course that's the difference.
"And accuracy?" she asked, glancing back at the hovering category.
Dr. F's gaze sharpened. "You are long-range specialized. This arena will deny you optimal distance."
The floor beneath her feet subtly reconfigured, walls sliding, structures rising and collapsing in simulated chaos.
Her lips pressed together. So you want to see me bleed.
"And survival rate?" she asked, voice quieter now.
Dr. F answered without hesitation. "Calculated until cessation of biological function."
The words landed like a blade laid gently against her throat.
Sophia closed her eyes for half a second—just enough to gather herself—then opened them again.
"When do we start?" she asked.
The corners of Dr. F's mouth twitched—not quite a smile, but something close.
"Now."
The arena lights dimmed.
