Zombie

Zombie is a condition which the affected can heal unnaturally. As long as one of the the three main organs; eyes (at least one), heart, and brain remain undamaged, any wound will heal over time. This ranges from a new limb, or a new body from just one vital organ. Normal wounds heal quicker, meaning tiny cuts and the like mean almost nothing.

It is more common in males, and to have it happen in females is rare.

The only way to kill them is to destroy all three parts; eyes, heart, and brain. Diseases, age, or ect. will not kill them.
