I saw a lot of sharp (no pun intended) Shredders out there and had the fodder to do it so here it is.
Recipe:
Torso, upper arms: LCSH Star
Thighs: HML Ronin
Forearms and shins: Bullseye.
The head is just some Aves I stuffed up into his helmet and drilled a hole into. The armor and weapons are from a Jakks Sub-Zero and various Shredder figures and the cape is from an MM Batman.

This was a lot of fun to do. Thanks for looking!
