SCP 6005
OC: Keter
Containment procedures:
Once an infected person (or animal) is spotted, it will then get incinerated. But once on the third stage, the whole area within a mile will be under quarantine and lit ablaze to stop further spread of XF-935.
Description:
SCP 6005 can grow up to 20 to 30 feet tall. DNA samples traced back to human, Pando, and Cordyceps DNA. SCP 6005 ejects a cloud of microscopic spores (XF-935), at least three micrometers in size, once every five hours. Fungus type.
Once infected with XF-935, the subject will experience the following symptoms phases:
1. increased weight gain, redish/brown blotches on the skin resembling scab or scar tissue
2. organ tissue getting replaced by tree cells (pando DNA), extended periods of time being out side
3. appendages resembling roots growing out from the souls of the victims feet (or hooves, or paws, etc… depending on the animal) scab/scar tissue engulfs the subject, multiple limbs will grow on the subject from the chest, back, or sides (usually under the arm pits)
:all three phases will go through a time span of four or five days. These phases will accelerate in hot areas in or outside.
