Missing toy Parts!

[Biskit74_Zombie_Slayer]

I recently discovered my DC massacre action figure is missing his cape.
Mine
But in the unopened package you can see his cape here. Unopened

I was wondering if there are any websites or stores that focus on pieces of toys, where I could maybe find the cape.

I have sentimental attachment to this toy, and would rather complete him then buy a new one. Ive tried searching ebay and amazon and cant seem to find only a cape. I have also tried my local craigslist with no luck there either.

Any help would be much appreciated. sweatdrop
