This is a super-simple custom. I can't possibly be the first person to have done this, but here it is anyway: Tiger Force Snake Eyes.

Many people dislike this version of Snake Eyes, but I fell in love with it once it was recolored for the Desert Patrol Squad, Heavy Assault Squad, and its head was used for Winter Operations. When I noticed that the TRU Tiger Force pack included blacks and blues as well as tiger stripes, I realized this would be an ideal use for SEv4.

Personally, I use this mold of Snake Eyes as "Black Dragon" (the ninja from G.I. Joe Extreme) but that's neither here nor there.
