Hello. Since SCP-513 is officially on the list of SCPs being added to the SCP Containment Breach Unity Remake, I figured he would need a bit of a redesign, and not just be a still model just floating around. So much more could be done with this SCP in the Unity Remake, so I'll just leave this here.
"Descriptions of SCP-513-1's appearance are largely unreliable. Test subjects are unable to provide complete accounts of sightings due to their exhaustion, degraded mental health, and disruptive hypervigilance. However, all interrogations thus far indicate that SCP-513-1 is a tall, emaciated humanoid with abnormally large hands."
