It's got to be fatal guage. In kh2 the drive orbs were a yellow/orange, and the drive gauge was yellow/orange. So it would make sense that since the fatal guage is blue, the fatal orbs would be blue as well. They look more like crystals then orbs though...
Edit: Doesn't fatal mode use the "focus" bar? The focus and fatal bar are the same thing. I guess "Focus" is the correct name for it though. I think that blue orbs fill up focus bar which activate fatal mode
