Malkath Shapur is a Kroot from the planet Pech, the homeworld of all Kroot within the Tau Empire. Half a metre taller than the average human, he is a towering and well-built specimen of his kind. His leathery skin bearing a dark brown colour, with streaks of black tribal tattoos of his former clan. His hair is that of quills, that have been dyed black with flicks of dark red at their tips. He possesses small green eyes above a large beak-like maw that makes up his mouth. Several smaller quills dot over his body like stray hairs. He possesses four taloned fingers and an opposable thumb, and five taloned toes. He can speak Low Gothic in a gravelly, hoarse voice, but with a fair degree of fluency, as well as a handful of other alien languages.

Nowadays, he wears the old tribal-made leathers from his home, knitted and repaired several times, and here and there patched together with pieces of armour taken from some of his various kills to use as patch-work armour, though its mostly all light in order to enable him to remain mobile. He carries two rifles, his standard Kroot Rifle, and Hunting Rifle across his back, with a pouch for a handful of pulse ammunition clips for guns by his belt, as well as several other pouches for his "trophies". 

Like many Kroot, Malkath ended up leaving his Warsphere as a mercenary for the highest contractor in search of finding the best warriors to consume their DNA and return to make greater warriors for the Kroot. Though unlike many who actually fulfilled this task and eventually returned home, the thrill of the hunt and visceral intensity of fighting and overcoming prey that were worthy warriors filled Malkath with so much pleasure that he decided not to return to his Warsphere and instead stick it out and make a life-long career out of being a mercenary. He has spent roughly 20 years in various companies and bands or even just as a lone merc as private security, fighting various opponents from Orks, to Human gangsters, immperial guardsmen, cultists, and pirates, and even a handful of Dark Eldar and other alien races. Each encounter with a foe of particular ferocity, skill, or strength, he honours them by consuming their remains and gaining some of their attributes as his genetics morph to the accommodate the fresh DNA. 

This has led to various side-effects, ranging from his more "human" behaviours and sensibilities such as his capacity for drinking, his five fingers and toes, and his ability to even speak imperial languages. He also possesses some aspects of the cunning and treacherous mind of the Dark Eldar to contribute to his sense of strategy and quick-thinking, and some aspects of the strength of the Ork along with their capacity for collecting trophies (lately he's been starting a private personal collection of trophies off of the kills he has deemed worthy to consume rather than just consuming and leaving the all the remains). Such a cocktail of DNA has made Malkath highly adaptable and given him considerable abilities, but it has also come at the cost of giving him a variant of multiple personality disorder. He will literally become almost a completely different person depending on the situation, making him potentially extremely dangerous to be around in combat situations especially as his more primal, predator personality takes control and he seeks to fight and kill any opponent near him. To this end, he usually likes to work on his own, or with people who are capable of dealing with his major swings.
