Warpath

They were created to be killing machines. Highly intelligent, resourceful, and deceptively complex, the Jem'Hadar are a species engineered for war and programmed at the genetic level for one purpose: to fight until death as soldiers of the sprawling stellar empire known as the Dominion. No Jem'Hadar has ever lived thirty years, and not even their masters, the shape-shifting Founders, know what such a creature is capable of becoming were it to be freed of its servitude.
