SCP-4756 is a tall, lanky, humanoid looking creature with black wrinkled skin, covered in thick protruding red veins on the outside of the body, and is to be kept in a 25x25x25, 5 foot thick titanium box. It drips an extremely thin and slippery black acidic substance from its it's thumbs. Upon contact with a solid object the substance (which through extensive testing has shown it is it's own element) turns into an extremely corrosive black gas, which emits a terrible odor, while refracting zero light. SCP-4756 claims it only corrodes on his command. Through testing we have found this to be true, researchers are able to get the SCP to cooperate with them. The SCP has be observed to be very manipulative towards the researchers attempting to get them to come into contact with the substance. Attacks by the SCP in the past have shown the SCP uses manipulation skills to lure a victim towards it. SCP-4756 then protrudes long sharp nails from its thumbs, then penetrates the victims temples, and sprays the black substance into the victims brain, corroding it, and denigrating it into nothing, giving the victim a 100% death rate. Attempts to kill SCP-4756 result in it turning to the corrosive black gas to protect itself. Attempting to transport it into deep space has zero affect, as it just appeers back into the containment center seeking revenge within 24 hours.

Interviews with SCP-4756 have shown it is male, and aged at 138 years old, supposedly being created by SCP-001, but has been shown through research to be from an entirely different universe, and ages older than god himself. Interviews also concluded that SCP-4756 has admittedly killed over 1000 victims.
