Day 8 of Spongie's Skintober prompt list.

Dividers are tall, thin Necromorphs with the unique ability to break apart into smaller creatures, the head itself is the main Necromorph. The head attempts to suffocate the victim by latching onto one's neck and uses its powerful appendages to sever the victim's head from the rest of the victim's body and hijack it with its arms, taking control of the host's nervous system presumably by attaching itself into the spine.

(P.S. This was kinda rushed ngl. I was originally going to give Isaac a suit from Dead Space 2 but ran out of time. I may still do something like that in the future but idk)
