Final Fantasy X
Tidus Arm and Props

I made the arm using craft foam covered by embossed vinyl. (I wrote a tutorial about how to emboss vinyl here.)

The shields were made from foamcore board covered with craft foam and styrene. (Elastic straps hold them to the wearer's arm.) The Brotherhood Sword was made from PVC, foamcore board, styrene, and epoxy putty (which was used to make the sculptural elements on the hilt.)
