SCP-054 (v2)
Description: Out of the water, the subject most often appears as a female humanoid with a mean volume of 90 L comprised entirely of water (other forms are possible, commonly geometric shapes). When it enters a body of water, it becomes indistinguishable from its surroundings. The subject must periodically return to a body of water in order to maintain its volume due to evaporation. Initially found in ████████, it was moved to Site-08 for further study. Subject was initially curious about Foundation personnel and seemed to enjoy interacting with maintenance staff and researchers, and mimicking their forms. After a number of weeks, the creature apparently felt comfortable enough to remain out of the water during routine monitoring, though it retreated when attempts were made to study its composition.
SCP-054 is apparently composed of normal water, with no detectable differences compared to ordinary spring water from the same source. No thermal, electromagnetic, biological, or other phenomenon has ever been detected in its "body" that would suggest how it animates. Water lost by SCP-054 to evaporation exhibits no special properties when condensed.
Experiments with SCP-054 were halted following [DATA EXPUNGED] two researchers injured. After this incident containment protocols were updated. Subject thereafter exhibited signs of mistrust and aggression around male personnel (which made up the majority of the original research staff). Subject reclassified Euclid.
