Various B.A.T.S. - Cast Battle Damaged Heads
Avengers: AoU Ultron/Damaged Iron Legion - Torso, arms, legs
Termination Salvation: T-700 - Shoulders, Elbows, Hips

I've been wanting to tackle these since the 5 point of articulation Age of Ultron figures came out. The cheap Terminators on ebay are a great source for adding articulation to robots and droids, it's just a lot of work making everything work together. Luckily, these guys are supposed to look pretty beat up so any rough spots kinda help sell the look. I'm really happy with how these guys came out, and I think Sam's illustrator might be my favorite artwork of all my Resurgence projects.
