Divider

A Divider is a tall, thin Necromorph  that is strong and tough. Once slain, the head, arms and legs separate and become independent creatures known as Components or Divider spawn. The Divider sub-sections are very fast and will damage and attempt to strangle a victim, but they are much weaker than the original Divider.

Dividers tend to be loners, but a pair, or a single Divider backed up by Exploders, are not unlikely. Its components (when separated) are strong when they are attacking but are weak and cannot take much damage.
