Hive Mind (Dead Space)

This massive creature that was sealed away by an unkown civilization; apparently the Hive Mind is the leader and the source of the Necromorphs.

Appearence
Like most of its underlings the creatures skin is possibly composed of dead tissues of the previous civilization, in a nutshell it is a towering worm like monster with tentacles and a flexible rib cage that lacks a sternum and inside it a line of organs and a mouth which is vital to the creature.

Abilities
It mostly uses its massive body to crush its foes and its tentacles to ensnare its victims, the Hive Minds true ability is to control other Necromorphs via telepathy even though it may act like a primitive animal it maybe incredibly inteligent.
