I've already got my theories on Uranus as being Dragon, control of the weather, what can be better than that when you travel on the sea. It is clearly related to the sky and weather balls who can control weather to some extent have as mentioned enough power to bring the world to its destruction. Another option would be that the weather balls are the actual weapon, but I'm pretty sure that's not the case.

As for Pluton I am not totally sure what its power would be, nor do I know if it's actually human or a warship as so many believe it is. It could be the special body of Blackbeard, but it could be still something yet to be shown. I already have fanon ideas, but nothing from the series except for Teach's weird power to eat more DFs >_>
