i just got dengar today, and i'm very pleased with this figure.
the head sculpt is excellent, just like the prototype photos we've seen. the head bandage is molded plastic instead of cloth, but works very well, and has a weathered look to it.
the body is the older style "hall of fame" type body, like the 12" luke with tauntaun recently had. not perfect, but it works well for this figure.
the armor is also very well done. i'm glad to say it's all new parts, not reused parts from the snowtrooper or stormtrooper. it also looks like hasbro has finally figured out that the thigh armor should be snug, as it fits well, unlike the clone trooper armor.
the prototype photos we saw of dengar used white armor, painted the correct "rust" color, but appeared to be peeling off. well, don't worry about that here. the armor, as best i can tell is molded in a bronze/rust colored plastic.
the back pack snaps on and is well detailed.
my only complaint about this figure is his blaster rifle. it is molded in a light greyish color with a brown stock. a little "weathering" would of realy helped this weapon.
overall, i think this figure is Bossk quality, an A+ in my book.
