The Shriek base figure works great for a wide variety of characters. I still haven't figured out how to properly disassemble the joints on these newer Marvel Legends figures with no visible peg holes, but I didn't need to to make a Catwoman from this figure.

Both the masked and unmasked heads are casts of the head from the McFarlane Multiverse Unmasked Batwoman and sculpted over the resulting cast. The collar is from Dazzler, the hands are from Black Cat and the feet are from Sharon Carter Agent 13. I sculpted on additional details on the glove cuffs and boots, as well as the zipper. The whip is made from the handle of the Black Cat whip, with twisty wire for the whip itself. Painted it all up. Thanks for looking!
