You died… and then woke in a testing tube.

At first it felt like drowning. A cold liquid pressed in on your lungs and skin, suffocating you in silence. Your eyes shot open to a pale glow and the hum of machinery. Horror struck—you were sealed inside glass.

Your chest heaved. Panic swelled, but then memories cut through the fog like broken glass. A name pulsed in your mind: Amaya… Amaya the Hedgehog.

Visions followed—the ARK orbiting Earth, Gerald Robotnik’s gentle laugh, Maria’s bright smile, and finally him… Shadow, the brother you once stood beside as you gazed at the stars. You weren’t just a test subject. You were his sister, created one year after him, not as a weapon but as hope.

Then came the raid. G.U.N. soldiers, alarms, Maria’s final cry, Shadow’s roar, and your capsule sealing as darkness swallowed you. Fifty years of silence… until now.

Rage filled you. You struck the glass until it shattered, collapsing onto the floor, coughing as air filled your lungs. When you caught your reflection in a cracked mirror, crimson eyes stared back—quills black with red streaks, so like Shadow yet uniquely your own.

You searched the ruined lab and found clothing: a black bodysuit, a baggy hoodie, shorts, and red-black boots that fit as though made for you. A worn backpack held rations, kits, and a datapad. With it, you stepped into a world fifty years older.

Months later…

Station Square felt unreal after endless darkness. One morning, Chris Thorndyke and his classmates spotted you perched on a tree branch, calm and untouchable.

“Wow… you’re amazing!” Helen whispered. Danny grinned. “Are you a superhero or something?” You gave a faint smile. “...You could say that.”

A thunderous explosion cut you off. You leapt down, muttering, “Sorry, gotta go,” and sprinted toward the chaos. Chris ran after you.

In the city streets, Sonic and his friends confronted Dr. Eggman in a towering mech, Chaos Emerald in its claw.

“Knock it off, Egghead,” Sonic snapped. Cream and Cheese shouted, “Yeah! Chao!” Amy swung her hammer. “Give it back!” Tails glared. “That emerald isn’t yours!”

Eggman laughed. “And what if I don’t?!”

From the crowd, Chris’s grandfather called, “Get that emerald, Sonic!” His eyes landed on you. “Whoa… who’s your new friend?” Chris stammered, “I—I don’t know… she hasn’t told me her name yet.”

The street quaked as a crimson streak struck down—Shadow the Hedgehog stood tall, eyes locked on the emerald. “That doesn’t belong to you.”

Rouge glided down with a smirk. “You never learn, Eggman.” Omega’s heavy steps shook the ground. “TARGET: EGGMAN. ELIMINATION SEQUENCE READY.”

The air rippled with psychic power—Silver floated down, eyes glowing. “The future won’t fall into your hands.” Blaze followed, flames curling around her. “Return the emerald, or face me.”

Then three voices rang out: “Hold it right there!” “We’re on the case!” “Chaotix Detective Agency reporting in!”

Vector cracked his fists. “You’re makin’ a mess, Eggman—that’s bad for business!” Espio’s kunai gleamed. “Stand down.” Charmy zipped around. “Yay! This is gonna be awesome!”

The street teemed with heroes, every eye locked on Eggman. Sonic grinned. “Well, Eggman… looks like the odds aren’t in your favor.”

Eggman snarled, the emerald blazing in his mech’s claw. “You fools! I’ll crush you all!”
