|[List of appearances]|
The Sith warrior has light grey legs with a dark red leg joint. Both the leg joint and the legs feature printing, with the legs depicting silver armour plates with black outlining and the top of the leg joint featuring the bottom of a belt. The Sith warrior's torso piece is also dark red, with dark grey arms and light grey hands. Printing for sections of armour continue on this torso piece on the front and the back of the body in silver and dark grey, including a predominant plate of armour in the centre of the chest and a thin plate of armour running down the warrior's back. The top of the belt is also depicted on both sides.
The Sith warrior's head is dark grey, and has a mask printed on which is predominantly silver with black outlining. Some sections of the mask are left dark grey, including at the bottom and in the mouth area, and a grey strip running between the eyes and widening on the forehead. Some areas of gold are also present; one to each side of the mouth area and one below. The warrior's mask has two black areas left for eyeholes, and red eyes are shown, glowing from inside the mask.
Darth Marr was a human male who served on the Sith Empire's Dark Council for over forty years, during the Great Galactic, Cold and Galactic Wars. Due to infighting within the Council, Marr rose to a leadership position alongside Darths Mortis and Ravage, and was eventually given sole command of the Imperial Military. Marr was proficient with the use of a lightsaber, and was known to be skilled in the use of Force Lightning.
- Darth Marr is the first minifigure to come armed with a lightsaber that has a black hilt.
- This minifigure was only ever referred to as a "Sith warrior" until 2014, where a display of over 500 Star Wars minifigures at the 2014 Comic-Con International: San Diego identified him as Darth Marr. However despite this, the minifigure's head is based on Darth Nox's mask, not Marr's. Additionally, in the Star Wars universe, neither Marr nor Nox were known to ever wield two lightsabers at once.
