Thanks to HISSTANK.com boards member iDzBowl for posting up images of his custom sculpted Sigma 6 Cobra La Royal Guard.
"I decided to try my hand at my first Sigma 6 style custom. This one I've spent the last 6 months on. As you may know, there are no Sigma 6 Royal Guard figures so about 75% of this figure is sculpted by yours truly. The head is 100% sculpted."
Many more Sigma 6 Cobra La Royal Guard images after the jump.
