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. Just as the Goffs clan loves violence and aggression, so the Evil Sunz love speed. The Evil Sunz have adopted the general Ork maxim that "Red 'uns go faster" as their clan motto. Evil Sunz prize fast vehicles like Ork Warbikes, Warbuggies and Trukks on which their Boyz can ride to battle. To assist their highly-mobile warbands, the Evil Sunz have many Mekboyz, to keep those vehicles tuned and running. 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. Beyond even a Speed Freak's delirium there are also Flyboyz, whose need for speed has driven them into the air in search of ever greater thrills, piloting the Ork's Fightas and Fighta-Bommers.
The Evil Sunz have an unquenchable need to careen around the battlefield at great speed, ploughing into the ranks of the enemy before racing off to cause more carnage elsewhere. Though a force of Evil Sunz will include foot troops, these infantry mobs will usually save up their teeth for when they can afford a vehicle of their own. Evil Sunz Warbosses will usually have their vehicle painted red from grille to exhaust. The habit of painting vehicles red has its roots in the ritual covering of the Ork's mounts with the blood of the foe, a practice that is still observed by some of the older Evil Sunz tribes. The Evil Sunz never stay in one place for long, and are always on the lookout for new victims and settlements to slaughter. The armies of the Imperium find it extremely difficult to engage the Evil Sunz on anything other than the Orks' terms, for the clan's super-charged Trukks, Battlewagons and Warbuggies can outmanoeuvre the heavy vehicles of the Imperium with ease.
The Evil Sunz are noted for the skill of their Bikeboyz. These Ork terror-bikers dress in leathers, wear the Evil Sunz totem, are bedecked with chains and bike harnesses, and wear steel-toed, multibuckled, black biker boots. Their foreheads are often decorated with metal studs screwed directly into their thick skulls. [Source: wikia]
