Kharn is the greatest of all the champions to Khorne's name, second only to Angron in power. He wields a chain-axe, known as Gorechild rimmed with the teeth of a Mica Dragon.

At the Battle of Skalathrax, Kharn became both legendary and infamous amongst his legion. With a unholy fervor, he slew in a mad-rage Emperor's Children and World Eaters alike, earning him the name The Betrayer, scattering the legion into individual warbands forever. He stalked the burning cities of Skalathrax like the bloody-avatar of Khorne himself, unstoppable and terrifying.

For a time afterwards he stalked the Eye of Terror as a bloody butcher, murdering all he came across for Khorne.

During the Thirteenth Black Crusade, however, he had a chance at something more. Now Kharn stalks the bloody streets and plains of Cadia, reaping a terrible harvest from the already sapped defenders of the planet.
