Rogue Trader: K'Lurg Ratcha, Renegade Ogryn Cyborg

The product of an experimental brain enhancement operation gone horribly right, Ogryn Sergeant K'Lurg Ratcha emerged from the operating room with vastly enhanced intelligence, vastly enhanced mechanical aptitude and a vastly enhanced predilection and talent for extreme violence.

His Imperial creators were taken very much offguard by the extent of their own success but did not live long enough to regret it.  K'Lurg carved his way out of the facility before the anesthetic wore off and escaped into the surrounding jungle of the death world of Proteus.

The death world was no more ready for K'Lurg than the Imperial facility had been.  The cybernetically enhanced Ogryn soon fought his way back out of the jungle and onto a space ship with which he embarked on a career of piracy .

K'Lurg soon earned such an appallingly villainous reputation that the worst scum the Wailing Reach had to offer flocking to his banner.  For decades the renegade Ogryn terrorized the space lanes.  He became a major thorn in the side of The Dead Men space marines chapter, who were forced to devote ever increasing resources to the campaign to extirpate K'Lurg and his band of criminals.

Over several decades the Dead Men had several near successes in killing K'Lurg.  They poisoned him, shot him, Las-cannoned him, and destroyed a dam in order to flood a small valley on the planet Nepenthe which happened to have K'Lurg holed up at the bottom of it.  K'Lurg always survived.  The Dead Men justifiably believed they had finally succeeded in finishing their formidable foe when Captain Callixx of the 4th company severed K'Lurg's legs with a 2 handed chainsword in a desperate fight aboard K'Lurg's flagship, The Hungry Whore, then flushed the legless Ogryn out an airlock into space. Yet K'Lurg survived somehow, and was back in action within a few weeks, having replaced his lower limbs with an armored tracked chassis, and with his career goals re-oriented away from piracy and toward killing Dead Men.  It is thought that K'Lurg did in fact meet his final end when he was lured into a cottage on Ran by Chaplain. William Pil Grym and marines of the 6th company, who then called in artillery on said cottage, obliterating it with a direct hit from a one kiloton nuclear shell fired from a heavy howitzer.  No trace of K'Lurg's body was ever found, but thereafter K'Lurg's depredations permanently ceased.

K'Lurg shown some time after his brush with Captain Callix aboard The Hungry Whore, with his preferred personal weapon, a heavy beamer, and the armored tracked chassis he loved to use to grind close combat opponents to bloody pulp.

Ambush!  Famed bounty hunter Rufus Kraal, supported by hand-picked troopers of the 24th Geminions Imperial Guard Regiment, attempts to take K'Lurg by surprise.  Rufus barely escaped with his life.  None of his loyal guardsmen were as lucky.
