Bad Moons
The Bad Moons are a powerful and wealthy Ork tribe or clan. The Bad Moons are the richest of all the Ork clans. This is because their teeth grow faster than other Greenskins, meaning that even the lowliest Bad Moon has a steady supply of wealth. This is not regarded as an unfair advantage, as any Ork big and nasty enough can simply smash the teeth out of a Bad Moon's head. The Bad Moons essentially fulfill the role of a merchant caste in what passes for Ork society, and have a reputation for showing off.
Blood Axes
The Blood Axes are an Ork tribe or clan that has actually been known to work alongside the Imperial forces on occasion. The Blood Axes are held by the other Ork clans to be a bunch of untrustworthy gits. They trade openly with the Imperium of Man, parley with the foe and will even consider retreating from battle if faced with insurmountable odds.
Death Skulls
The Death Skulls are an Ork tribe or clan dedicated to stealing and plundering. The Death Skulls are truly plunderers without equal. They are tremendously good at looting, borrowing, scrounging, scavenging, and stealing things from their fellow Orks, and notoriously bad at returning them. Death Skulls would make capable scientists and excellent engineers if their fascination for new things lasted longer than the time it took to steal them.
Evil Sunz
The Evil Sunz are an Ork tribe or clan who are dedicated to speed and making as loud a noise as possible when in combat. The Evil Sunz have adopted the general Ork maxim that "Red 'uns go faster" as their clan motto. By far the largest number of Ork Speed Freeks come from the Evil Sunz clan. An Ork's love of speed can easily affect its brain, to the point where an Ork becomes addicted to the thrill of a wild ride into battle.
Goffs
The Goffs are an Ork tribe of clan who are the largest and most agrressive of the known Greenskin clans. The Goffs are the biggest, meanest and most brutish of all their kind, and that's saying something since they are Orks. Of all the Ork clans, the Goffs are the most inspired by the thrill and thunder of battle. Goffs will take any excuse to start a brawl, even amongst themselves.
Snakebites
The Snakebites are a well-known tribe or "Klan" of Orks. The Snakebites are considered to be a backward tribe by many of the more technologically-advanced tribes of Orks, for they still follow the old ways of the Ork race and often remain Feral Orks even after they gain access to more advanced technology. As a result of their rugged lifestyle, the Snakebites are usually weather-beaten and as tough as an old boot.
