PLEASE CHECK OUT THE REWRITTEN VERSION- The Experimentalist
You are an scp. Secure, contain, protect. Tch, right. You're called SCP-3042, your real name is (Y/N), though. You are a shape shifter. Well kind of. Your molecules and DNA are unstable and there for can take the shape of anything you chose, sometimes it happens automatically, changing to best fit your surrounding. You have been classified as Euclid, and have been staying at the Foundation for a few years. With your unique power, you can practically get out of any room or teleport, by focusing your molecules into a different place. You also aren't affected by anything, for example, SCP-409 had no affect on you, and SCP-178 couldn't even touch you, seeing as he practically couldn't touch you. But, let's see how you face with the dreaded Doctor, SCP-49.
Oliver winded up in the backrooms. He doesn't know anything about it at all. He's afraid and lonely. He decides to do something very, very stupid. Oliver yells for help, and someone almost immidiately grabs him from behind and covers his mouth. Why? Because there was a weird creature just some meters ahead, and it definitely heard him. If it wasn't for this person, he'd be dead. But why? Why would they do that? "Only to get rid of the stalker", They said.
