We are moving onto another Keter class that is dangerous to the human population and that is scp-939. There are two scp-939 in its containment. They did do a test against scp-682 to see if they can kill him but it didn't go well since scp-682 ripped one up and will make the other one back to the door and banged on it.

Classification: Keter class, Endothermic pack based predators

Powers and abilities: Superhuman physical characteristic, enhanced senses(enhanced hearing), vocal replication(can imitate a human speech and voice perfectly, even without hearing them speak), minor mind manipulation(SCP-939 exhales an Amnestic(referred to as "AMN-C227") that causes temporary anterograde amnesia, inhibiting memory formation for the duration of exposure for an average 30 minutes after the exposure, and that causes disorientation and mild hallucinations when the exposure ends).

Attack potency: Wall level(Its prey are usually killed with a single bite to the cranium or neck They can bite with a force of 35 Megapascals, this would make their bite force 7.58 times stronger than a great white shark and 1.32 times stronger than the one of a Saltwater Crocodile)

Speed: Normal human

Lifting strength: Unknown, likely Class 1

Striking strength: Wall Class

Durability: Unknown, likely Wall level

Stamina: high

Range: Standard melee range

Standard equipment: none

Intelligence: At least average(SCP-939 is rather intelligent, using both its ability to lure prey with its voice replication and AMN-C227 to develop an efficient strategy for hunting humans) 

Weakness: none notable

Notable attacks:

Vocal replication( SCP-939 has the ability to copy and imitate human speech, despite not having heard an individual speak, and has been documented mimicking the vocalization of other species.)

AMN-C227(SCP-939 exhales AMN-C227, which cause temporary anterograde amnesia for the duration of and for 30 minutes after the exposure to AMN-C227. After the exposure ends, disorientation and mild hallucination will occur)

Notable losses:

SCP-3199 (SCP-foundation) Scp-3199 profile(9-B versions and speed was equalized)

SCP-682 (SCP-foundation) SCP-682 profile(article cannon was used and speed was equalized)
