Throwing a little Sigma Six in the mix, Dead Man Customs has done a fantastic job paying homage to Tony Stark with his Custom Iron Man Sigma Six crossover figure.  It is unique when a customizer can use parts from other toy lines to create the right look and feel.  With the Sigma Six line from GI Joe, the figures were made using very hard lines and angles and I think that goes very well with the world of Iron Man and creates a nice canvas and medium to create one of a kind pieces.  This Iron Man boasts an incredible 27 points of articulation and the faceplate on his helmet and chest were sculpted with Aves Fixit Sculpt.  Also featured is a removable chest blast for when the fight needs to go to the next level.  To view more photos, especially of the cool chest piece, head over to eBay and check out Custom Iron Man Sigma Six crossover figure.
