Yeah, fair can spike. I discovered this earlier today and checked it with Sa10 to see if he could do it, and he got it to work a couple times. However, it is unbelievably difficult to do. Your opponent has to be basically right under you and you have to hit with the last frame of Fairs hitbox for it to spike. I've gotten it to work once, and Sa10 got it to work twice, and I've got a replay of it actually working. If anyone else could go test it and see if there is an easier way, please do so and let me know.
