Editing House Goliath (section)

===Stimmers and Zerkers===
While gene-enhancement and muscle grafts are common in the Imperium, for some members of House Goliath the process of enhancement through drugs, stimms, gene therapy and the simple addition of adding more layers of vat grown muscle pushes far past what might be considered the safe limit, creating a '''Stimmer''' who are even larger and stronger than their normal brothers and sisters. For the most part these individuals are well reasoned and clear thinking individuals, though prone to the occasional roid induced temper tantrum and have an even shorter lifespan than the average Vatborn goliath.

However, Stimmers live their lives on a knife-edge; the slightest imbalance of chemical stimms can cause a spontaneous eruption of mutation and uncontrolled growth, resulting in a gigantic flesh hulk called a '''Zerker.'''

Amazingly, Zerkers are even stronger than [[Ogryn]]s, and with the addition of combat stimms can be far more savage. While this might sound like the ultimate expression of House Goliath's ideals, the downsides exaggerate the flaws already inherent in the processes the House uses on their regular gangers. Zerkers are forced to live in a state of metabolic chaos, with spontaneous bone spur mutations and uncontrolled muscle growth as common side effects. There is also the added drawback of practically eliminating higher brain functions meaning that Zerkers are little better than living battering rams who can contribute nothing to the further upkeep of their house or gang.
