Savage Opress is exclusive to LEGO Star Wars set 7957, Dathomir Speeder.
Minifigure Parts and Accessories
Opress is made up of 5 parts - head piece, head, body gear, torso, and leg assembly.
The head piece is a new part designed to fit on a standard minifigure head, but give the look and impression of the Zabrak horns.
The head is black with yellow print to resemble the facial tattoos of the Dathomirian Zabraks known as the 'Nightbrothers'.
The torso and arms are black with yellow hands. A black version of part 47577 covers the torso. The print on the body gear resembles pauldrons and body armor. Aside from this figure, this body gear will appear on the Series 4 Hockey Player. It is not known if there is print on the front or back of the torso itself.
The legs and hips are black with no visible print.
The accessories for this figure are a double-bladed lightsaber with trans-red blades and a spear/axe blade combo.
Army Building Potential
The ABP for this figure is low. Although a new figure for the LEGO Star Wars universe, there's nothing of note that would make this figure sought after in multiples.
A marquee character in this season of The Clone Wars, Savage Opress may be sought after to ensure a complete LEGO Star Wars minifig collection. Although it has met with mixed reviews to date, the head piece is unique and could have custom applications. The body gear could also be a desirable piece.
