Here is the new Legacy Collection Nien Nunb. I've always liked Nien Nunb, but have never found a decent figure of him, so I picked this up right away when I found it at Wal-Mart.
As with the other Legacy figures, hes got great articulation. Ball jointed head, shoulders, elbows, torso, knees and ankles. He's got Swivel hips and wrists. He's also got nice detail on the face and chest plate. The helmet/hose is removable. The other hose isn't fully removable, because one end is glued into the chest plate.
I believe the body sculpt is the same used in the Rebel Pilot Legacy packs, but I haven't gotten any of those yet, so I'm not positive.
The droid piece included is the right leg to R3-M3.
