Darth Marr has light grey, printed legs and a dark red hip piece. He also has a dark red printed chest, dark grey arms and light grey hands. His head is also light grey and printed, and sports a dark red hood. He has two lightsabers, both with black hilts and crimson blades, and are used with the "rings" on the hilt facing up and the "prongs" facing down.
Darth Marr was a Human male Dark Lord of the Sith and a member of the Sith Empire's ruling Dark Council during the Great Galactic War, Cold War, and renewed conflict with the Galactic Republic. A fearsome warrior and stalwart defender of the Empire, Darth Marr assumed a seat on the Dark Council in his early twenties, leading the Sphere of Defense of the Empire as he drove back entire armies and halted Republic offensives during the Great War. By the end of the war, Marr had trained an apprentice named Darth Lachris to the rank of Sith Lord and was one of only seven remaining Councilors. He continued to strengthen Imperial defenses and prepare for the inevitable conflict throughout the Cold War, distancing himself from the power plays and treachery that plagued the Council and weakened the Empire.
As war broke out with the Republic, Marr watched as the Dark Council's numbers dwindled thanks to both the enemy and internal feuding, and he assumed a leadership role alongside fellow Councilors Darth Mortis and Darth Ravage after the deaths of Darth Baras and Darth Decimus, the heads of the Spheres of Military Offense and Military Strategy, left him in sole command of the Imperial Military.
- When Darth Marr was released as a minifigure in 2013, he was labeled only as Sith Warrior.
