Puppeteer

Appearance
Puppeteers are small squid-like Grimm that are 2.25 meters at their longest. They have a flat mantle with a single piece of bone armor and the rest of their body is jet black and cartilaginous. They possess 4 tentacles at 2 meters long and a thick beak containing vocal cords inside.

Special traits
On its own, the puppeteer is docile and actively avoids combat. Even if attacked, it will not fight back, only flee. The danger of the puppeteer however, is its ability to inhabit recently deceased corpses. Provided the muscle structure and brain are still intact, the puppeteer works by burrowing its 4 main tentacles into the corpse's limbs where they emit slight electrical charges in addition to moving themselves, hence why this Grimm is called "Puppeteer" The beak goes into the brain and nervous system to better emulate talking. Once all five anchor points have been established, the mantle is flattened along the back of the host, bone-side up and preferably underneath clothing or armor.

Puppeteers observe fighting to learn how to best command a potential host; the sound of their voice, what weapons they prefer, all of that. Older Puppeteers have demonstrated a multitude of fighting styles, learned from many hosts and battles. Older puppeteers also know how to cry for help to lure unsuspecting hunters into an ambush or possibly gain access to a restricted area.

Weaknesses
The puppeteer does not sustain the living functions of the corpse it is using. When the host naturally rots away, the puppeteer must leave to find another one. Also, the puppeteer can be killed with a single, good blow to the mantle if the fighter manages to flank around and hit the mantle hard enough.
