Gork and Mork
From Lexicanum
Gork and Mork are the twin gods of the Orks. The difference between the two gods is very subtle, one being cunningly brutal while the other is brutally cunning, respectively. The upshot is Mork hits you when you aren't looking and Gork hits you harder when you are.
Both of these deities are dedicated to war as the entire Ork species is war loving. Certainly, there is no room in Ork society for other gods as war makes up their entire life. Both gods are believed to offer help to individual Orks in battle, but in the grand scheme, it doesn't matter which god is worshipped. Generally, Gork is worshipped by the regular boyz as a more direct manisfestation of brutal power, when Mork is the God of Oddboyz, the cunning Orks like Meks and Warpheads.
The Ork racial character, strong and virtually indestructible, has its reflection in the warp in the form of the equally strong and indestructible Ork gods. The titanic Ork Gargants are constructed in the two gods' image; consequently, they are living idols and war machines. The Mekboys who build them work from a vision held within their imagination, usually inspired during times of Waa-Ork.
In Ork mythology, Gork and Mork regularly confront the Chaos gods and the gods of other alien races. Gork and Mork are never defeated.
Ghazghkull Mag Uruk Thraka is the prophet of Gork and Mork, the two gods supposedly guiding his wars of conquest against the Imperium, revealing the best ways of defeating his enemies. This was apparent in the twin invasions of Armageddon, the Second War for Armageddon and the Third War for Armageddon.
