SCP-682, also known as the hard-to-destroy reptile, is a Keter creature of the SCP Foundation. The creature is the only one that the Foundation wants dead, simply because it wants to kill all human life. The reason the creature gained its alias is because it can regenerate its entire form from the tiniest particle. So far, nothing has been able to kill it permantently. The creature is one of the most dangerous items/creatures in possession by the foundation for both this and its hatred of all life unlike itself, with the exception of SCP-053. The creature has managed to escape 6 times, with another 17 failed attempts. In all 6 attempts, everyone the Foundation could get was sent after it. It appears to be a gorgonopsid, a prehistoric reptile close to the evolutionary lines of mammals.
Regeneration - SCP-682 has been able to bring itself back from death each time the Foundation has attempted to eliminate it. These attempts includes bullets, acid, fire, bludgeons, and some other SCPs, including SCP-173 and SCP-582
Superhuman strength, speed and reflexes - No matter the size, SCP-682 is faster and stronger than any human. This changes with form, but always stays relatively high.
Rapid Adaptation - SCP-682 also has the ability to evolve and change its body as needed, usually as a counter to the Foundation's most recent attempt to kill it. It can consume organic or inorganic materials to provide for the necessary mass and has been known to grow additional organs, change its size, and both resist and subvert other SCPs.
