The Soul Calibur series has some of the coolest character designs in fighting games, or any other genre, so naturally cosplayers will get busy making these costumes. Here are Sophitia and Rapheal about to begin a duel, or perhaps dance. They both look pretty sweet, but I have to give bonus points to Sophitia for being cute. Unfair, I know.
I don't even know where I would begin if I wanted to create a Nightmare costume, but someone did, and it looks fantastic. This guy (girl?) also made the Soul Edge, with the eye and everything. I presume a Taki costume would be easier to make, but harder to look good in. Now I kind of wish to see more live-action Soul Calibur characters, but in a movie. Now there's a thought.
