Item #: SCP-427
Object Class: Keter
Special Containment Procedures: 2 Layer concrete with a camera, microphone, and audio device inside.
Description: It's very tall and it can expand it's arms and turn them into spikes, hammers, etc. It can also turn into a liquid if its in a bad situation. If you were to drink this liquid, you could die in two ways, the first being when you swallow the liquid, he turns back into his normal form and in this way, kills you. The other case is that he doesn't turn back, in which you will die in the next 24 hours and he will still be alive, just more red since he mixed up with the blood. Also while in this form he can mix in with water which can trick people into drinking it. Can not speak to human beings and can imitate sounds of a few other SCPs.
