Wow, quite interesting to see all the rejected and touched up ideas! Ralf and Clark actually kinda look like some of their concept was carried over to the XII-born designs.
Could that woman in the mask with the whip be a prototype design for what'd eventually become Whip? (O.o) And who is the chick in the dress on the page opposite of her?
I kinda like Sie and Chin's designs... Brian Battler looks like a FoTNS reference, which would have made him much cooler than her turned out to be, haha. Syo Kirishima Kyo has always been pretty cool looking, I was glad he had a costume of that in the Maximum Impact series (and was a Striker in 2000.)
So WEIRD stuff going on with those later arts. A graduate-student looking guy? Mecha Heavy D!?
Thanks for sharing, Fiol!
