Someone may have already said it but my version

Name: Manticore

Species: Monster

Description: An ancient creature thought to be long extinct to the extent hunters don't have much knowledge on them Manticores were fearsome creatures who lived to eat and produce young. Located mainly in India they appear humanoid except for the scorpion tail and retractable rows of teeth in their mouths. They also possess poisonous barbs in their palms which they can fire to paralyse prey so they can feast on live prey. They make sure nothing is left behind. Being stung with the tail results in death but is rarely used unless they feeling extremely threatened as it prefers live prey. They are asexual and lay a number of eggs which is proportional to the food available. They are impervious to all weapons and forms of injury (including decapitation) and can only be killed with the sting of a manticore stabbed into the heart of the Manticore which is located on the right side of their bodies. The hunters in India managed to collect enough venom from Manticores to hunt them to near extinction which is why they keep a low profile.

For the story of supernatural a dormant egg was excavated in India and brought to America for a museum but unknowingly the Manticore is unleashed and starts to feast and find suitable places to lay eggs. Cue Sam & Dean.
