Lol I had that same exact idea but I didn't start it yet :P Lol. I like to draw manga so I might make a book on that. I'm just brainstorming but I think the storyline will be on two brothers, who get sucked into a vortex and wake up in a different planet, but they can survive there. An absolute remake of earth they have to figure out a way to get back home (with help from a few people), and get back to their time. But its gonna be drawn in manga so its gonna take what 5 months? xD.
Then you'll love the story I'm writing if that's the case. The main character is a Lucario, but the difference is that it's not Trainer vs Trainer or Pokemon vs Pokemon. It's about stealth, skill, and survival.
If you look at my signature it takes you right to the story.
It's not finished yet (I'm only on my 12th chapter), but I'm making progress.
