Ghidorah, the Three-Headed Monster

"[on the disappearance of the princess] Yes, I think she survived because she fell into a gap between dimensions. You may not be aware of this...but there are other dimensions besides those we know. And there's a whole other world therein. The explosion created a gap between the two worlds. She was saved when she fell into it."
