They look awesome. I guess I didn't think about what Eddie's back might look like, I love what you did there. As far as L&F Tripwire, I just expected a simple repaint, but you definitely made him your own. And like Pluv said, the removable helmet, poor Tripwire, eight versions and every single one is the same mold/design, o-ring or ME and no removable helmet.
Night Adder's head (called The Brute if I remember correctly), the Eddie head and upper and lower torso and Selina's body are all from Slayer. So bummered they are no longer around. They made such great stuff.
