Uzi/Tekagi: 2013 G.I.Joe Tactical Ninja Team Snake Eyes
The Rest: Marauders Task Force Parts

One of the more infamous figures of the vintage run, Ninja Force Snake Eyes is completely laughable. The idea to reduce articulation for some asinine action feature should be a fireable offense. As an aside, when the G.I.Joe Retaliation 5POA figures came out, at the Joe convention that next year, the guys at the Hasbro apologized for doing 5POA figures and promised never to do it again.
So, this custom is an attempt on my end to see what a fully articulated Ninja Force Snake Eyes might look like. Oh! and if you squeeze his legs together, he'll throw a cup of YoJoe Cola in Hawk's face. The kids'll LOVE it!
