This fic has been rebooted, please see the newer version from the author's page. The name of the fic is same, just with a (Rebooted) added at the end, so you can simply search it too. 
Now this version has higher smut content, and lower plot content and the reboot would have the opposite, so read it as per your convience and horny levels.

Waking up in the Pokémon world as a Ditto is like a wet dream come true... or a nightmare, depending on how you look at it. I'm not sure which is worse - being a slimy, shape-shifting blob or knowing that all raunchy-ass hentai Mangas were actually going to find some use.  
But here's the bright side, when life throws you some motherfucking lemons, you make some goddamn lemonade. When life gives you a slimy, shape-shifting body, you become the coolest motherfucker there ever was.
This is going to be one hell of a ride and I ain't got any pennies in my pocket.

Disclaimer: This Pokémon fanfic is a work of fan-made fiction, and I don't own jack shit. The Pokémon franchise belongs to Game Freak, Nintendo, and all those other clever folks who created this amazing universe. I'm just a rowdy degenerate messing around with their toys. Don't sue me, I'm broke. Also, expect some naughty language, dark themes, and general tomfoolery. You've been warned, so don't come crying to me when your precious Pikachu gets roflstomped. Now, sit back, relax, and let's get this wild ride started!
