Ork

Biology
Ork biology is quite unique: they are a symbiotic fusion of fungus and animal. The animal fights, eats, and moves while the fungus is responsible for reproductive capability. Instead of tedious (but enjoyable) breeding and excruciating (yet rewarding) birth, each Ork grows out of the ground. Each is genetically encoded with the knowledge of how to build and service a "bolt" pistol and battle ax. "Mekboyz", or mechanics, are encoded with knowledge of heavier (and cooler) weapons, such as the "Zzap! Gun" and "Shokk Attack Gun". This has led to speculation that they were created as some sort of biological weapon for a long forgotten conflict..

Language
Ork culture is centered around combat. This comes out in their speech, they sound like British street thugs, and are thus able to speak with ' 'umies' and part of their their language is made up of punching each other. Other oddities in their speach-patterns include the fact the can't pronounce the 'h' at all, and replace the letters 'er' with 'ah', so a gunner turns into a 'gunnah' and a summer turns into a 'summah', they also tend to use the sounds a weapon makes, or it's purpose into it's name, so any close combat weapon is called a 'choppah' (chopper) since it's used to chop with.

Music
Ork music is similar to human Industrial Rock.

Military
"Rank" is determined by height and weight, like boxers or wrestlers. A short, slender (for them) ork who has killed many opponents is still subject to a taller, broader Ork who has killed fewer opponents; although, generally, the more fighting an Ork endures, the bigger he tends to get.

Cuisine
Orks have 'iron stomachs'. They will generally eat their meat raw or in some cases, still alive, and they will eat any mushroom that looks tasty, even the poison ones. They also enjoy a powerful liquor, "fungus beer". Since their fuel is usually ethanol-based, it's safe (for them) to drink.

Religion
Orks worship two gods: Gork and Mork, gods of Cunning and Fighting. nobody (not even the Orks) can tell who is who. Their priests ("wyrdboyz") can summon a manifestation of these two, usually a Monty Python-esque foot or hand to crush their enemies. they also have street-preacher analouges called "Yellerz".

The Waagh
The Waagh is a gestalt psychic field generated by each Ork, and grows stronger the more orks that are around, and how much fighting is occuring. The Waagh is a cross between a religious crusade, mass migration, and a giant pub brawl. The psychic field generated by the Waagh causes the laws of physics to deteriorate, depending on what the Orks believe. For example, if they believe that vehicles painted red will go faster, the vehicles will indeed go faster. It allows them to create and use weapons that would not work in the hands of any other species, only working if they are in the hands of an Ork. Ork Waaghs have been known to swallow entire star systems and clusters, with anywhere between millions to billions of Orks.

Weapons

 * Shoota and Slugga: A pistol or autorifle that fires explosive bullets.
 * Choppa: A large battle ax, usually forged from bulkhead plating, but they have been known to steal the fancier close-combat chain and power weapons from other races.
 * Burna: A flamethrower that is often used as a tiger-torch by their mechanics, giving it more damage against vehicles.
 * Zzap! Gun: A tesla coil-like electricity projector.
 * Shokk Attack Gun: A large weapon with an impressive warp disruptor on the end. It is used to fire a stream of a smaller sub-species of orkoid through the warp (Hyperspace, the alternate dimension where Daemons manifest), where they are invariably driven mad with fear. When the beam makes contact with a solid surface, the unfortunate little monster pops back into real-space, flailing and biting.
 * Mega Blasta: A plasma cannon.
