Scp-3631
Class:KETER
Description: Looks like a 30 and 33 year old man, he has a lot of intellect, when he is injured he leaves a corrosive toxic vapor, his containment is rigid and his containment area is a new found metal that appears to be vapor immune this metal is called ritunium, its appearance is strange looking like the victim's biggest fears, so the cell security staff are trained not to be afraid of anything.I will give more details below.
from the line below you have to be careful what you will read you have been warned
Scp-3631 It has the ability to revive those it killed, making immediate removal of the deceased bodies, but if it succeeds it will be named Scp-3931-A and it should be immediately eliminated as 3931-A contains a highly contagious disease and the individual with The disease (infected by the virus) has a 75% chance of dying before treatment ends.
it proves to be fire resistant and looks like a decaying corpse just like scp-106 (the interdimensional senior)
he was burned but he resisted he has to be fed 7 times a day otherwise he is in a state of narrow fury to the point of strangling anyone around.
if you find a decomposing 33 or 30 year old man walking down the street call the foundation immediately
