Head: '91 Snake Eyes
All else: '89 Frag Viper
I've recently been working to expand my Battle Corps Subset, and include characters that weren't otherwise a part of it. Snake Eyes was one that I wanted to include despite him being released in '91, and then having a Ninja Force release a few years later. I actually decided to draw inspiration from those two versions and sort of combine them into a new Battle Corps figure.
Other than painting, the only real mods were the addition of straps on the back and waist to sheathe the two swords.
