Pokémon - But it was in the top percentage...

I got a used copy of Pearl a few years ago that still had the previous owner's saves on it. The guy had a ludicrously overleveled Infernape (near level 100 before the elite four) and a Shellos in a master ball. I still have no idea what the hell the guy was doing.

First time I played pokemon I used it on a Seel…
At least I used him till the very end.
