So, serious question! Well, sort of! I've been thinking about it, at any rate!
Do the rules of one universe apply to them all because we're all connected by one universe really? I mean. Say someone dies in another world. I can bring them to mine and revive them at least once. Is that possible? I mean, are the Other Worlds in other worlds the same or is there only one Other World?
AH. This is when someone like Vegeta is good to have around. Or even Piccolo! I'm getting hungry just trying to think about this!
