So while it is nerdy, I want to create the Call of Duty: Zombies characters out of LEGO in real life to play with or model. But I can't find any sites where I can create them. Can someone help?
Try Minifigs.me! It allows for creation using almost every part, plus custom parts.
Also try BrickLink, which has a catalogue of nearly every LEGO piece in existence. (For sale!)
