Ice powers! A kingdom for my own!
Well, besides masturbating to know what having a pussy feels like, I would simply...well, find a better ruler and freeze myself until his reign ends
And if I oversleep and wake up in a bad situation like, WWII...even better! Not only do I get to be praised by the Germans as a godess, but now I don't have to deal with any of the shitty characters from the first movie! OH! What if wake up around The Incredibles? I would leave Frozone out of work!
SO MANY THINGS I'D DO! I LIKE IT!
So yes, masturbation, find a better ruler for my kingdom, and then...do as I please
