Editing Xenos (section)

===Once-offs===
These are Xenos who fall into the same category as the oft-mentioned 'there was a Cult Uprising' fluff extracts in 40k. These are characterised by tending to be nothing more than a mention of their existence, before a quick mention that they are now all dead, usually due to some Space Marine force attacking. These Xenos tend to not even have an illusion of threat, such as Chaff Xenos, and are very much just hand-waved away the same way Cult Uprisings tend to be, being very quickly destroyed and without any significant impact.

Due to the very nature of their existence there are few examples of these types of Xenos, seeing as they tend to simply exist as a single name mentioned to have already been destroyed. Two common examples which are frequently reused, however, are the Genestealer Cults and [[Exodites]]. Exodites, in particular, are usually only brought up in a story to describe how they die awfully.

'''Examples incude:'''
* [[Genestealer Cult]] 
* [[Exodites]]

Separate to these well-defined roles, all Xenos play the part of the 'Worf Effect' role, dying or losing so as to establish their opponent's power. Whether it is to Chaos or the Imperium, Xenos will frequently only appear to be bested in some or other manner, usually to solidfy how powerful a particular character or faction of the Imperium or Chaos is. This category is very much often occupied by specific Xenos characters too, and tied to certain events, and can be found most frequently in Black Library novels, in which almost any Xenos antagonist introduced will be built up as a threat but, almost, inevitably be either dead or running by the end of the story.
