Item #: SCP-XXXX
Object class: Euclid Keter
Special Containment Procedures: SCP-XXXX is to be kept in a containment cell approximately 40 meters away from the facility. The facility has to be far from any human civilization. In order to keep SCP-XXXX from escaping it is advised that the containment cell to be made sound proof and to have the walls layered with lead to deter SCP-XXXX from wanting to escape. A minimum of nine (9) level 3 personnel are to permitted to be on guard duty. Authorization from a level 4 administrator is required. Three (3) guard is to keep all higher than 16000 hertz from being heard by SCP-XXXX. Six (6) of the other personnel are to guard the area, if it enters it's berserk stage you are ordered to report to the higher ups immediately. Frequencies that exceed 16000 hertz cause SCP-XXXX to enter a berserk stage, once in it’s berserk state you are advised to make as little noise as possible, even the slightest sound will prompt SCP-XXXX of your current location. After approximately three (3) hours in the berserk stage SCP-XXXX will become incapacitated. Nearest personnel are to bring SCP-XXXX back to the containment room.
Description: SCP-XXXX resembles a grotesque humanoid biped Lepidoptera. In simplified words it seems to be a human figure and a moth had fused together to become one. Eye site is nearly nonexistent, SCP-XXXX relies on its hearing ability. Through experiments we have confirmed that frequencies higher than 16000 hertz can be heard 20 meters away and is immune to most poisons. When in it’s berserk stage it’s capable of making a horrendous shrill, that drives any man crazy, it is also able to imbue an intense feeling of terror (during this time it is advised to not make any noise as hard as it may sound.) There seems to be no limit to SCP-XXXX’s strength, it’s able to make dents and eventually obliterate thick layers of titanium with horrifying ease, but due to unknown reasons SCP-XXXX is sensitive to lead, upon contact the skin begins to form rashes. Although it’s just a deterrent, it won’t be stopped with just that. SCP-XXXX possess steel hard bones and can reach break neck speeds. In the berserk state the skin becomes hardened as if it were iron.
First Enclosure: SCP-XXXX was first stationed at facility ████████ in ██████. SCP-XXXX had at first seemed to be a simple Euclid class that had immense strength and was capable of going into a berserk like state. Due to our foolishness and ignorance we hadn’t realized that when provoked into the berserk state due to frequencies that go over 16000 hertz cause SCP-XXXX to enter a new berserk stage. The capabilities were, appalling. That facility had been completely wiped out due to the unknown capabilities at that time.
Reference: As to date SCP-XXXX has been the cause for numerous deaths and multiple occasions of escaping the containment chamber. The most recent incident had occurred on ███-██-██, SCP-XXXX had escaped and killed 83 out of 150 personnel before being subdued. Due to the feeling of terror that it spreads, agents and personnel are left unable to fight back.
Experiment F
Because of the incident that had occurred at facility ████████, we are performing tests in order to understand the limit of SCP-XXXX's ability to hear frequencies. We are testing frequencies that are lower than 16000 hertz in order not to provoke the berserk stage from emerging. This will be the fourth trial after 3 failures that will not be listed.
Result: Frequencies of 16000 hertz that are 20 meters away are unable to be heard by SCP-XXXX.
Experiment P-45
We are testing the effectiveness of certain poisons on SCP-XXXX due to it being immune to certain poisons such a cyanide and even mustard gas.
Result: After 44 tests on SCP-XXXX the most effective poison seems to be Botulinum, although large doses are required to subdue SCP-XXXX, it is the most efficient. It is advised to use a tranquilizer gun due to the deadly features of Botulinum.
Experiment M-L
Testing metals in order to find out what metal should be layered in the walls of the containment chamber.
Result: Upon SCP-XXXX being shot with lead bullets during many occasions red rashes have been seen to form upon the skin. When SCP-XXXX comes in contact with lead it becomes exasperated.
Audio Log 1
Dr.███████: "Recording number 37. We have found out so far that certain metals and frequencies of sound cause immense distress to SCP-XXXX. Due to this we will layer the walls in the containment cell in order to deter SCP-XXXX from wanting to escape. Also sound waves that exceed 16000 hertz are capable of causing it to enter a, "berserk" stage, is what everyone's calling it. We've also discovered that when 20 meters away SCP-XXXX is unable to hear the frequencies. We will have the facility be approximately 40 meters away from the containment cell and have the cell be sound proof with lower frequencies…."

Audio Log 2
Agent Fraiser: "Dr.███████ said that the experiments tested on the frequencies and sound waves or some shit have proven to show to be the cause of the berserk mode."
Agent Jesper: "Well shit, so your telling me that we can't talk because if we do, that thing in the cell with fucking break through the wall and kill us all. Isn't this just amazing, how am I supposed to do my 10 hour shifts guarding the damn thing without talking to anyone!"
Agent Fraiser: "Let's just be happy that we know how not to get that, thing, into it's killing frenzy state, don't wanna end up like ████████."

Audio Log 3
Dr.███████: "This is an incredible break through! We've just learned that with large doses of Botulinum SCP-XXXX becomes incapacitated. We now have a way to subdue SCP-XXXX when hell breaks loose like like at ████████. Although that is true, Botulinum is a dangerous poison capable of paralyzing the user if not handled correctly, or worse, killing them."
