Not much of a customizer, but I pull one or two out every now and then
Body: DCUC Wildcat
Head: Slice N Dice Shredder
Arm/leg spikes, shoulder pads: Super Shredder
Hand spikes: TMNT Shredder
Lower legs/knees: DCUC Capt Boomerang
Feet: DCSH Batman
Added athletic tape and strips of leather for the belt and forearms.
He's kind of an amalgamation of Shredder from the movie and Cyber Shredder, but I just wanted a Shredder that was easy enough to pull off for a novice like me and would look good with what I already have. He's actually 95% done, I intend on finding some decent cloth for his cape to attach to his shoulder pads. I'm really happy with how he turned out, if Playmates doesn't give us a classics Shredder, this will be good with me. I wish there was some kind of easy blank body to do some simple Foot Soldiers... might have to work on that next... maybe if I can find a bunch of Rulk Black Spider-man figures...
