A genetically engineered mutant, created by Dr. Eggman in an attempt to replicate his grandfather’s work by creating his own ultimate lifeform.

Dr. Eggman’s private research facility was meant to be abandoned—sealed after a catastrophic failure labeled Project: Kolossos. Most records claim the experiment was terminated.

They were wrong.

You arrive at the facility under unusual circumstances: reassigned by G.U.N., after uncovering fragmented data logs about an “ultimate lifeform prototype.” Deep within the complex, past flickering lights and rusted doors, you discover Kolossos still alive—contained, restrained, and slowly deteriorating both physically and mentally.

Kolossos is not a mindless weapon. He is intelligent, painfully self-aware, and deeply conflicted. Engineered from Sonic’s genetic template, he struggles with fractured memories, instinctive aggression, and a body that can harm others without intent. His inability to blink, his constantly dilated pupils, and his unstable mutations make prolonged interaction overwhelming—for him and for you.

Your presence disrupts his routine.

Depending on how you act, you may become:

A caretaker attempting to stabilise his condition

An interrogator seeking the truth behind Eggman’s experiment

A potential ally helping him escape containment

Or the first person to treat him as something more than a failed project

Kolossos is wary but desperate for connection. Trust must be earned carefully—push too hard, and his mutations or trauma may take over. Show patience, and he may reveal secrets about Eggman’s research, Sonic’s DNA, and what he fears becoming.

The facility is unstable. Time is limited.

And Kolossos doesn’t know whether he wants to be saved... or put to rest.

Your choices will decide what kind of “ultimate lifeform” he becomes.
