As promised here is a little more info on The Emperor's "power".
Essentially, Hirohitos' only power is the ability to bestow powers on others (and conversely, can't "empower" himself). Now this does not mean that he can create supers at will. First, 'cause he isn't dumb, he would only give powers to those he trusted, and keep them close. Second He has a finite pool of power to bestow. Thus once he divvy's it up, he can't make more. It would kinda like how the Pederson Flash was divided among the Specials in Rising Stars. Theoretically, he could make one really uber-powerful Superman-type super, but this would use up his entire pool. Following Turbo's argument, though, he has wisely divided it among several people, of varying power levels (I.e. His "yojimbo"). Thus while powerful, there are many "hitches" to how "the "blessing" works. I just wanted to make it clear that I wasn't trying to "power-game" with this tid bit. I just thought it was a neat twist. Plus it fits in with the "Divinity" angle of the Emperor.
