Editing Ork (section)

===Chaos Orks & Mutant Orks===
Back in the days of [[Rogue Trader]], [[Chaos]] was considered an equal opportunity employer instead of just relying on corrupted [[Space Marines]] and [[human]]s, which admittedly makes more sense. As such Chaos Orks were very much a thing, and in fact came in two distinct groups; [[Stormboyz]] of [[Khorne]] and general Chaos Orks. The basic idea was that most Stormboyz who didn't grow out of being Stormboyz would eventually gravitate to worshipping Khorne, as this was back in the day when Khorne had more of an "honorable, disciplined warrior" motif to him and thus he was considered a fine role model by the Stormboyz, whose whole thing was being disciplined, organized and professional compared to the anarchic barbarians of other orks. Other orks could also fall to Chaos, often but not always Khorne, without being still part of the Stormboyz cult. Both sets of Chaos-worshipping orks were regarded as "un-orky" by their mainstream fellows, but would sometimes be hired as mercenaries by warbosses in particular need of their killing power, or who just didn't really bother vetting their latest Freebooter hire all that well - they'd also happily join Chaos armies, where they were welcomed.

The big difference mechanically is that Khorne's Stormboyz were Stormboyz with the Mark of Khorne, whilst Chaos Orks were Orks with Chaos Marks, Chaos Gifts and Mutations.

Separate to both of these Mutant Orks, who had no intention of worshipping Chaos, but still got mutated as a result of exposure to Warp energies, radiation, psychic phenomena from the local weirdboy or the experiments of a Mekboy or Painboy. These wretches were social outcasts, and sometimes were allowed to join a Waaagh as expendable cannon fodder - not that they cared, because they hoped to ultimately prove they were still properly Orky. These poor sods sometimes mutated all the way into Chaos Spawn-OHGODGLARBABALAAGAAH!

\*Ahem.* While there has been no mention of nonhuman and nondaemon Chaos forces for several editions (save some background Xeno races worshipping Chaos), the idea of Chaos Orks makes perfect sense when you think about it. Not only because there's no real reason the Ruinous Powers should only corrupt humans, but also because there are Quadrillions or Orks in the galaxy, so at least ''some'' of them are bound to decide that [[Khorne]] is more killy than [[Gork]] or that [[Tzeentch]] is more cunnin' than [[Mork]], regarldess of whether or not they actually are. [[Nurgle]] would probably take a liking to them as well, not just because Nurgle likes everybody, but also because Ork spores tend to infect and kill a planet's ecosystem in much the same way a mundane fungus might a plant or animal. [[Slaanesh]] would seem to have the fewest Orkish worshippers, since the most common way Orks get their rocks off would end up empowering Khorne more, but then you remember that Slaanesh thing is 'excess' and what do orks like to do in excess of even to the point of self destruction? [[Speed Freek|Go fast]] and be [[Dakka|loud]]. [[Malal]] doesn't really seem to have anything going for him in this department, admittedly, but then he doesn't really have anything against him either like Slaanesh does, and maybe a couple of Mekboyz decided to make enough of a boom to destroy the universe.

Ultimately the lore has arrived at this explanation for Orks and Chaos: Their psychology just doesn't give much fertile soil for Chaos to take root in. While they love fighting, they don't really experience hatred that Khorne could feed on. They have no sexuality or appreciation of excesses beyond the banal joy of constant war (an objective lie given their fondness for fungus beer), so Slaanesh has nothing to tempt them with. Similarly, their wants and schemes are so unsophisticated and direct that there's nothing for Tzeentch to manipulate, and their biological nature so coarse and brutal in its simplicity that Nurgle can only be impressed as these grunting warrior mushrooms conquer the galaxy.
However, 6th ed Chaos Space Marines codex did mention an invading ork infected with a daemonic plague prior to Mortarion and Plague Marines showing up on the assaulted shrine world ; though in this case they were unwillig allies at best, victims of Chaos at worst, and not truly Nugrglite converts.
