SCP-610 is a Keter-class anomaly classified as a highly contagious transformative disease. Infection begins as a rash, spreads into scar tissue, and soon reshapes the victim’s body into a mass of rubbery flesh. The resulting forms are recorded as growing by absorbing additional limbs and organs at random.
The heart of the horror is proliferation that cannot be controlled. Flesh swelling as if with a will of its own, the body losing its human form, makes even the nearest territory — one’s own body — impossible to trust. As a threat that refuses containment and spreads without end, it shares the horror of un-ending things.
