Here is my ap.
Race: Chaos Space Marine of Nurgle
Appearance: See above, sorry i couldn't figure out how to make it smaller.
Description: A member of the Order of Rust, a Nergul cult that worshiped the collapse of mechanized troops, the crumbling of buildings, ect. They prefered to revel in the rot of the inanimate, not the living as with most Nurgle worshipers. As such Khebok is a Havok, somthing his legion specialized in for the purpose of destroying the machine, especialy on forgeworlds. As ceramite cannot actualy rust or tarnish, the layers of rust and grime covering him are a sidefect of his worship, similar to a Night Lord's plasma coating or an Alpha Legion's scales. Being a Havok, he loves heavy weapons, especialy ones with lots and lots of high rate of fire. Sure some Havoks will advocate slower weapons for thier ability to destroy tanks and buildings, but he feels at his best when he's laying down a stream of fire to slaughter lightly armored masses. Besides which, he felt he go the best of both worlds. With his autocannon, he can sythe through infantry with a decent fie rate, and pound through the armor of lighter vehicles, liek that fight with the Tau. Sure a missile will blow up a suite, but the autocannon was somthing special. Onc a round had found it's way though, it didn't blow. It just stopped, the pilot dead inside, a testiment to how pathetic the armor was. It had proven to be rather demoralizing. He'd learned since then that terror tactics and removing an enemies feelings of safety were almost as good a way to cause torment as to slowly peel off thier skin. Plus you could even do the second part later.
History: Born on a chaos world, Kulkahjka, he had proven through his crule deprevity and love of inflicting pain that he was worthy of becoming one of the initiates, one of whom would become one of the true sons of chaos. Through backstabing and pointing the blame elsewhere, he eventualy managed to murder his way through the competition untill only twelve were left of the fivehundered that started. These wee the most crule, mallicious, devious, and blood thirsty of the lot, all worthy of being sons, but only one would make it. That was determined by streight up fights to the death. At last, having killed the final chalenger (Khebok never bothered remembering the wretches names) with the use of a poison needle cleverly hidden in his own mouth, Khebok had earned his ultimate reward. The transformation into a Chaos Marine took five excruciatinly agonizing and terror filled years, but when it was done it had been worth it. He was now Asturas, stronger, faster, and more powerful than any man. Indeed, with his bare hands he could kill a city full of unarmed cililians and not recieve a bruise in return. Add in his wargear, and a normal man was helpless, left mewling for the Corpse Emperor before the might of Chaos.
Plausible reason to have joined up with "Da Crew": Unfortunantly, due to a certain warlords incompitance, the cruiser he was statined on got wiped out. Luckily he had made it to one of the few working savior pods in time, even if he did have to kill Poiil to get it. Stranded in space, he might have perished there if not for the fact that, fifty years later, he was picked up by Da Crew. Awakening from stasis he found some greens touching...HIS AUTOCANON! How dare they! He'd murdered for it fair and square, and if the pigs wanted it, they'd have to kill him for it. Khebok then realized the orcs must have thought he was already dead if they were going through his stuff. Well then this serves them right for not knowing what stasis was. Snatching up his bolt pistol, he poped three of the orcs before they knew what ahppened. The resulting melee resulted in six more dead orcs before Khebok was finally subdued. He was about to be killed when a voice boomed 'What jost a boit.' A hige nob, one of the biggest Khebok had ever seen, and he'd killed quite a few in his liftime. 'Now den, why you banga and choppa ma boyz fer?" he asked, running one of his powerclaws under the Marines chin. Looking it squarly in the eye, Khebok replied "They touched my gun." Teh nob thhought about it for a minute, nodded, and said 'I like you umi, you gots gutz, taking on fifha choppas, cause they a whole bunch of ahm. How about yhaz join Da Crew? Could use a dakka lova like youz." Once he learned what Da Crew was, and figuring he'd get to spread destruction and without even having to compete with his brothers to get the credit and glory, he figured he might as well give them a destroying hand. And the next five years after that was bloody history.
Troops: A bit glumly, Khebok can't make a reliable heavy squad, as orcs can't aim, kroot dont shoot, genestealers are wasted out of melee, and grots and gretchins were worse than useless. He'd origionaly had hopes for the other humans, but none of them really had a nack for heavy weapons. Disgusted, he became the units only heavy eapon user, prefering his autocannon but changing it up if ordered. Against the nids, the high power to kill Warriors and other biggies as well as the rate to tea up gaunts made it the perfect choice (once again). For his second he took the only former guard he'd ever found compitant, Nills, who had surprised Khebok by being actualy rather skilled with a flammer. His last four were two guards, armed with fully loaded las with power clips to spare, and two orks with shootas and choppas. The guards would provide f\cover fire for the special weapons in the squad, while the orcs would chop anything that got through the defens\ces to them. Of course, he wasn't a slouch in melee either, especialy with the power ax he'd, ahem, 'aquired' on a previous mission.
