See lots of Different Pokemon

(And no before some wise guy asks there is not a Pokemon called Different!) One of your aims will be to complete your Pokedex by encountering and catching lots of different Pokemon. When you catch a Pokemon, its data will be recorded in your Pokedex automatically. If you visit Professor Rowan every once in a while, he'll tell you how your Pokedex is coming along. In order to catch all the Pokemon in the Sinnoh region and complete your Pokedex, you must trade with the Diamond and Pearl Versions, as well as with other Pokemon versions. Work together with your friends to get your Pokedex as complete as possible.
