Overmind

The Overmind is a massive, stationary mob that acts as the Zerg's primary hive mind.

Appearance
The Overmind is a massive creature with a single ocular organ in its center. Multiple tendrils extend from the center.

Abilities
The Overmind is able to rebuild itself if it is killed. It has 10,000 HP, and upon death, it will enter a cocoon. It will then take at least 2 in-game days to heal, but you can break the cocoon with TNT to permanently kill it. It is able to spawn Zerg units at will, even though that ability is reserved for hatcheries, lairs, and hives. It is also able to spread creep.

If there is a live Overmind at any time or any location within 400 blocks, cerebrates will be allowed to regenerate their health should they ever be damaged at 1 health point every 2 seconds.

The Overmind is the only zerg creature to be able to create cerebrates.

Other Info

 * An Overmind cannot spawn without the use of a spawn egg. If the player is in survival mode, he or she can construct a control artifact and have unlimited access to zerg spawn eggs.
 * There is a spawn egg available for the fully developed Overmind, the cocooned Overmind, and the Overmind's Egg.
