Kyubi was a terrific antagonist. How she turned the humans on each other through her machinations of summoning numerous phantoms/imposters of heroes, mystics and demons. She felt even more menacing than Orochi and Kiyomori. I wonder if Warriors Orochi 4 will continue her story after she killed Fu Xi, Nu Wa, and Shennong?
She definitely is a nice and devious antagonist and I love her design. I think that victory against Fu Xi etc, is more of a what if scenario from what I recall ( which was awesome ). I would love to see and play with her in a future Warrior Orochi game. WO3 is in my opinion the best Koei Tecmo game so far since there is a number of roster characters to choose from as well as modes that made the game even more fun.
