Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures: SCP-XXXX should be kept in a soundproof standard humanoid containment cell fitted with a freshwater pool which should be cleaned daily by a D-Class personnel. SCP-XXXX's cell is located in Site-54, when made it was only meant to be temporary but it was decided to keep SCP-XXXX there due to how hard it is to transport it.
Description: SCP-XXXX is a seemingly race-less female humanoid which is 2.43 metres (8 feet) tall. SCP-XXXX speaks an unknown language which, when examined by a linguist, was found to be a mix of Spanish, Italian, French and Romansh. SCP-XXXX is semi-aquatic and is able to stay underwater for two days at a time. SCP-XXXX has hair which is around 2 metres long, it is purple in colour and glows under UV light, its hair seems to grow at a much slower rate than the average human and it is cut every two (2) to three (3) years. The only time SCP-XXXX will willingly let someone in its cell is when its hair is being cut and when her pool is being cleaned.
When SCP-XXXX is heard singing, within two (2) minutes whoever listens will suffer a Brain Aneurysm which kills them instantly. SCP-XXXX is aware of the effect of her singing and has killed █ researchers with it, usually, this is in an attempt to breach, all of these attempts have been compromised. Due to the severity of her singing, SCP-XXXX was classified as Keter.
SCP-XXXX was reported to the foundation on ██/██/1995 after she was found surrounded by ██ people who had died due to the effect of her singing in a canal in Venice, Italy. While trying to contain SCP-XXXX, her singing resulted in the death of █ researchers and ██ guards. It took a total of nineteen (19) hours to contain SCP-XXXX.
