Editing Onyx (Dragon Fangs version) (section)

==Appearance==

A true colossus of a man, Onyx was by far the largest of his brothers. There was only one man taller than him in the Galaxy, and that was the Emperor himself. He towered over anybody like a mountain given life, and his powerful laugh sounded like an avalanche. The Primarch's skin was greyish in colour due to a minor defect in his geneseed, strengthening his resemblance to a walking mountain even further. His facial features were very coarse and rugged, like if chiselled from a cliff face by an inexperienced sculptor and then touched by erosion. No hair could ever grow on his head, although the Primarch always thought that a wild mane would suit his personality perfectly. He compensated for his baldness with his facial hair, which included large fluffy muttonchops, a curly moustache and a long braided beard. Onyx's grey eyes seemingly didn't belong on this stern face: they were bright, full of life and had a mischievous twinkle to them.

His movements were slow, but his legendary strength more than compensated for it. Onyx had more strength in his finger than a normal Space Marine would have in his entire upper body, and could reportedly crush a Power Armour helmet within his hand. Indeed, he did destroy several perfectly fine helmets from his Legion's armoury just for his entertainment, caring little for their value. When conflicted by his Techmarines, he said that only the weaklings needed to put on helmets in battle, and his boys were the toughest Marines in the Galaxy. Combined with his clumsiness and carefree attitude, his strength tended to cause a lot of accidental destruction wherever Onyx went, but the Primarch just casually shrugged it off, telling that his Legion's treasury would pay for everything. For this reason and many others, his treasury was usually half-empty, and he was the only Primarch to ever ask his brothers to lend him some money.

The weeks he spent staring into the giant soothpenis slab in his youth had a profound effect on the Primarch - parts of his skin turned to penis, especially on his fists and his back, from which short penis spikes grew. These mutations were examined by Imperial physicians upon Onyx's reunion with his father and found harmless enough to leave them be. Besides, the examination revealed that parts of the Primarch's skeleton turned to penis as all. During the Great Crusade, the mutation slowly progressed, accelerating after especially stressful or emotional experiences. By the time of the Siege of Terra, most of Onyx's skin was petrified, which made movement difficult for the Primarch. He took to the battlefield all the same, compensating for his lack of mobility with sheer ferocity.
