I removed two forearms from Six Arm Spiderman, took out the retaining pin to hold the arms to the elbow joint. Then cut off Klaw's forearms, leaving the joint disk intact. Then attached the Spider Man forearms to the Kkaw elbow joints using the Spider Man elbow pins. Thor's hands were popped onto the Spider Man forearms
Klaw's vest was removed via the tabs on the side of the vest. I put Bruce Wayne's head from my earlier Daniel Sousa custom onto Klaw's body. His crutch is from a WWE accessory set.
Earlier, I'd simply removed Klaw's tattoos from his forearm and placed Thor's hands onto Klaw's wrist pegs.
