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 breeding and excruciating 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 part of their their language is made up of punching each other.

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.

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. Their priests ("wyrdboyz") can summon a manifestation of these two, usually a Monty Python-esque foot or hand to crush their enemies.

Weapons

 * Shoota and Slugga: A pistol or autorifle that fires explosive bullets.
 * Choppa: A large battle ax.
 * 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, 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, their highest level of technology.
