Replicent

Replicents are fairly unique as a creature of Grimm. They have a blank humanoid shape to begin with, but can turn into a tar-like puddle, which it uses as a disgiuse/trap for any nearby people. What makes them one of the most grotesque and fear-inducing varieties of Grimm, however, is their power, they absorb any person they come into contact with, after their aura has been reduced to zero, and assimilate their memories and abilities into itself, the process in all known instances, is a permanent one. That is to say, after killing a Replicent, none of its victims returned, although, given this seems to be their feeding method, this is none too surprising.

While the Replicent is sturdy, and with enough victims, intelligent enough to tackle a well-armed and prepared Huntsman, they are not averse to taking easy meals, such as stray animals, family pets, and the occasional child who stayed out of their parent's sight for too long.
