Marcus Chen died on a Tuesday.
At least, that's what should have happened when the thing with too many teeth tore through his classroom door.
The red rain had fallen for only seven minutes. Seven minutes to transform eight billion humans into monsters. Seven minutes to end civilization.
"Run!" Marcus had screamed at his students, but it was already too late. Their skin bubbled and stretched as the crimson droplets seeped into their pores. Bright student Kaylee's face split open like a blooming flower of teeth. Football captain Damon's muscles swelled until his bones cracked through his skin, reforming into spikes.
Now Marcus was cornered in the chemistry lab, the principal's contorted form blocking the only exit. The once-respected administrator now stood nine feet tall, his suit hanging in tatters around a body that had become something from a nightmare.
"Why not me?" Marcus whispered, staring at his unchanged hands. The red rain had soaked him completely, yet he remained human while the world turned monstrous.
The creature lunged.
Marcus closed his eyes.
[EVOLUTION SYSTEM ACTIVATED]
The words blazed across his vision like blue fire.
[EMERGENCY SURVIVAL MODE ENGAGED]
[FIRST EVOLUTION AVAILABLE]
[ABSORB PREDATOR SPEED?]
"Yes!" Marcus gasped, not knowing how he knew to respond.
Fire erupted in his legs. He screamed as tendons snapped and regrew, muscle fibers densifying in seconds. The pain vanished as quickly as it had come, leaving behind a strange new power humming through his limbs.
When the principal's claws swiped through the air, Marcus was already across the room, moving with impossible speed.
The creature roared in confusion.
A new message flashed:
[EVOLUTION SUCCESSFUL]
[DEFEAT THE PREDATOR TO UNLOCK MORE ABILITIES]
Marcus eyed the broken glass beaker on the counter beside him. He wasn't just surviving now—he was evolving.
And in a world where humanity had vanished in seven minutes of red rain, evolution was the only path forward.

Evolution Rising: The Last Human

Marcus stood at the center of the vault's inner sanctum, a ring of ancient processors encircling him like a tribunal. Symbols flashed across the floor beneath his feet—glyphs in no known language, pulsing with a rhythm older than civilization.

Lucien and Ember waited just outside the threshold. Even they weren't permitted to step into the circle. Only Marcus.

Astra's voice echoed from the periphery. "Once this begins, your system will be unchained. No limiters. No guides. You'll be free… but that freedom might consume you."

Marcus exhaled slowly. "I've survived everything else. I'll survive this."

[SYSTEM UNCHAINING IN PROGRESS][CAUTION: CORE IDENTITY STABILITY UNVERIFIED]

The floor split open, revealing a cradle of light. Tendrils of pure data wrapped around his arms, his chest, his skull. A dozen evolution options erupted in his mind—each more monstrous than the last. Speed like light, claws forged from plasma, senses that reached beyond the planet itself.

But then came something different.

[Initiate Legacy Override? This may rewrite emotional cognition and suppress memory anchors.]

Marcus hesitated. If he accepted, he would gain unimaginable power. Enough to fight the Architects. Enough to protect what remained.

But he might lose himself.

[Override Declined][Custom Evolution Pathway: Defined by Emotional Anchor – "Kaylee"][Gene Chain Rebuilding...][New Class Acquired: WARDEN TYPE – HUMANITY'S LAST MEMORY]

Pain exploded through him—not the raw agony of mutation, but the searing burn of memory being forged into muscle. His veins glowed. Bones shifted. Not into monstrous blades or exoskeletal armor—but something… familiar. Human. Just sharper. Truer.

When the light faded, Marcus stood alone.

Taller. Stronger. His eyes now ringed with silver patterns that shimmered like distant stars. Not beast. Not machine.

Something that remembered everything.

[You Have Become: THE WARDEN][Unique Trait: Empathic Echo – Allows You to Channel the Strength of Lost Souls for Temporary Power Surges]

He looked up as the vault's ceiling shifted, revealing a panoramic hologram of the Earth… and the silent threat orbiting above it.

Lucien stepped forward, whistling low. "So… are you still Marcus Chen?"

Marcus cracked his knuckles. "No."

Then he smiled, eyes glowing faintly blue.

Astra approached, awe in her eyes.

"No," Marcus said, turning toward the exit.
