I wanted to make a version of Snake Eyes akin to the Sideshow figures and the POC/Ret versions of the character.
I used green stuff to attach the collar part from v.25 Snake Eyes torso, and made a ball joint attachment to fit the Torso. No modification was needed on the v.2 head, it fits perfectly.
There was also some green stuff applied to cover up the neckline of Armadillo's front torso.
The scabbard for the Scimitar is just a coffee stirrer, clipped with nail clippers.
