Invader Zim #42 Cover B Adler

Meet the Plim-an alien race that's never been beyond their own planet, never known the wonders of the universe. In fact, they have a prophecy that one day a hero will come crashing through their atmosphere, bringing tales from across the galaxy! So what happens when both ZIM and Dib crash-land on their planet? The prophecy only said there'd be ONE hero, so... which one of them could it be?
