All parts: Viper VvV (red version)
The red version of the Vipers was good, but it really needed the original colors. So I went about making a small army of modified, customized and repainted Vipers.
The torso holds most of the modifications. I shaved off the ribbing and sanded it smooth, then epoxied on a 'zipper' up the center.
Now that Hasbro has released repaints that do the Viper justice, these customs are now of no use. Sad but true.
