M'kar

M'kar the Reborn is a Daemon Prince of Chaos Undivided and the biggest failure since Abaddon. He has history of defeats reads like a who's who of the Imperium, all queuing up to bitch slap him. His one notable achievement is banishing everybody's favorite Mary Sue, Kaldor Draigo, to the warp. How this makes any sense when he has been repeatedly and humiliatingly defeated by lesser combatants is unclear, but can probably be blamed like everything else on Matt fucking Ward.

History

• M31: Contributes to the Horus Heresy by getting stabbed in the chest with a dagger. Inexplicably elevated to deamonhood by the powers of chaos.
• 799.M41: Attacks Acralem, killed by a young Kaldor Draigo.
• 878.M41: Attacks Ultramar, routed by Cato Sicarius.
• 935.M41: Seizes a star fort briefly, before being torn to ribbons by Marneus Calgar.
• 965.M41: Attempts to entrap and tempt Mephiston into chaos worship, choked to death.
• 997.M41: Transforms an agri-world into a chaos world using an artifact, only to lose the world to the Tyranids and the artifact to the Grey Knights.
• 999.M41: Attacks Acralem again, killed by Kaldor Draigo again. Manages to use the last of his power to throw Draigo in to the warp and curse him.
• 835999.M41: Back again after an absurdly convoluted plan. New army, attacks Ultramar again, juiced by the nearly limitless power of a star fort. Killed by Varro Tigurius, Marneus Calgar, and Cato Sicarius (or Uriel Ventris, depending on whether you read Ward or Graham McNeill's version. Hint: Go with McNeill, it's awesome).
