D'harhan was a male Niordi bounty hunter who hailed from the planet of Niorde in the Unknown Regions. Niorde came under attack by members of the Leech Legions during the Clone Wars, who were hired by a neighboring planet to attack Niorde as part of a war that had been fought between the two planets for a century. To defend his planet, D'harhan and several other Niordi underwent cybernetic alteration to their bodies to become living artillery weapons. However, despite the advantage of having D'harhan and the other weapons on their side, the Niordi lost the war, leaving D'harhan the only living weapon left. He and Boba Fett had a long past together, and held each other in high regard.
