Concept: The Grimm will inhabit any living vessel they can.  You may find yourself up against someone from your old Legion or a mutated polar bear.

Easily distinguishable once fully overtaken by The Grimm.  Their eyes turn a bioluminescent blue with veins of electric pink. This color radiates from their eye sockets as it seeps under their skin until the flesh cracks.
