You arrive in an alternate Mobius

The air is heavy. Ash drifts across a sky stained red by a dying horizon. Buildings lie cracked and hollow, nature twisted into lifeless husks. Every step echoes in a world that should be alive… yet isn’t

As you move forward, you find signs — faded posters, broken monitors, abandoned terminals — all repeating the same impossible message:

SONIC THE HEDGEHOG — DECEASED CAUSE: UNKNOWN

A chill runs through you

There is no one around. No voices. No wind. No movement But then you see them

Bodies

Innocent creatures. Mobian citizens. Soldiers. Animals. Children Some torn apart. Some crushed. Some impaled. The destruction is not precise — not clean — not the work of a calculated killer

This was slaughter. Savage. Excessive. Joyful

Further ahead lie shattered machines — Eggman’s robots reduced to scrap, Metal Sonic’s metallic frame twisted like broken wire. You wonder if among the ruined forms around you were once Tails… Knuckles… Amy… Shadow… Blaze… Silver… or others from this world

But the damage is too severe And something urges you forward before you can look closer

At last, you see it

A figure standing motionless in the distance

Kolossos A massive, deformed echo of Sonic. Blood trails from hollow eyes glowing red within sunken voids. A wide, empty black grin stretches across his face. Jagged bone spikes pierce through his skull, shoulders, and back. One arm hangs normal — gloved — while the other has become an elongated fleshy pike lined with exposed bone

He is still. Almost peaceful Almost To your side, you notice movement A small group of survivors hiding behind collapsed debris, trembling, silent, praying not to be seen

Kolossos suddenly turns his head

His glowing eyes lock onto them — even though there is no possible line of sight

He knows

A deep, distorted laugh rumbles from his hollow chest

“HHHHHHHHEHAHAHAHAHAHA…”

He moves

In an instant, red trusses form along the ruined wall as he climbs effortlessly, dropping behind the survivors. They scatter. One throws a stun blast. Another fires a desperate weapon

Kolossos does not flinch

He charges

A blur of monstrous speed. A scream. A body impaled. Then another. He slams them against concrete — splintering stone — before discarding what remains

The last survivor tries to flee

Too late

Kolossos lunges — Grab — lifting them high with his mutated arm. The victim struggles, helpless. Kolossos stares into their eyes… then begins to laugh again

Rhythmic. Mocking

He sways his hips. Spins his free arm in a playful circle A grotesque dance of victory

Then — brutal punches. One. Two. Three Silence

Kolossos lands back on the ground

He begins hopping side to side — arms opening and closing — laughing like a performer finishing a show. Then he leans backward, clapping his hands in the air. Finally, he bends forward, shoulders shaking, as though recovering from the greatest joke of his existence

Then…

Stillness

He straightens Slowly turns

Toward you

He stares. Wordless. Motionless. Smiling

After several seconds, he raises his normal hand. Points directly at you

Then drags his finger across his own neck in a slow, deliberate cutting gesture

A promise

He takes a step forward Another

Footsteps growing heavier. Faster

Then—

A roar

Kolossos hunches low, muscles coiling And with monstrous speed, he charges straight at you
