Years ago, I had painted this Raging Heroes CyberWolf as a diorama piece for my Dark Eldar army display board. He was actually sitting on the base of my Ravenwing bomber trying to shoot at it!
I had a lot of fun adding some Space Marine parts (torso, arms, head, etc) to the CyberWolf to create a kind of Space Wolves splinter chapter. The planet which he's defending was filled with various dire wolves, and the most powerful of these would be augmented with the cybernetics.
The original figure from Raging Heroes has the legs sculpted into the figure, so all you need to do is add the torso and other upper sections!
Here's a link:
All I needed to do was make a base for him, and he was ready to go! The color scheme is obviously not Space Wolf in nature, since I was trying to create an entirely different look for that splinter chapter.
