Wraith. This is based on a custom by Brian Hatch. I had to make something similar for myself.
The thought is that MARS took Stark tech and modded it for their own needs. Makes sense. And, IMO, makes the character that much more deadly.
Wraith is a character I really like, I just don't thing the 25th style figure did the character justice. Plus the Iron Man parts make the figure taller and more bulky, making him a more menacing presence.
