How to complete the Sinnoh Pokédex in Pokémon Shining Diamond and Shining Pearl
Completing the Sinnoh Pokédex is a key step to access to all the endgame contents of the two remakes of the fourth generation games of the Game Freak series. In fact, once you have registered all 150 creatures native to the region you can get the upgrade to the National Pokédex, which will allow you to capture even more Pokémon, including dozens and dozens of Legendaries. Some juicy endgame activities will unlock, such as rematches against Gym Leaders and the Battle Tower located on the Battle Zone island, a brand new area that you will unlock during the endgame. For more details, we recommend reading our guide on how to get the National Pokédex and what content it unlocks in the Shining Diamond and Shining Pearl endgame.
How to complete the Sinnoh Pokédex
In the Great Dungeons of Shining Diamond and Shining Pearl there are numerous species of Pokémon. If your goal is to get the National Pokédex, you will be happy to know that to "complete" the Sinnoh one you will simply need to register all the cards relating to the creatures of the region. To register a Pokémon just spot it at least once, you don't have to catch it, which for obvious reasons makes completing the Pokédex much easier.Indeed, facing all the Trainers that stand in front of you and exploring all of them the paths and caves of the game, even the optional ones, once you become Champions of the Pokémon League you may have already completed more than 80% of the Pokédex without even realizing it.
However, there are some rare or particular creatures that may be missing from your collection. Among them, for example, is Drifloon, a Ghost Pokémon that appears only in one area under specific conditions and owned by only one trainer throughout the game. Or, the legendary between Dialga and Palkia absent in your game version. In the next section of this guide, we have listed some of the Pokémon that are most likely missing from your collection and how to register them in the Pokédex.
The general advice is to face all the trainers you will find along the your path, as they are sometimes in the possession of rare creatures. In addition, in Pokémon Shining Diamond and Shining Pearl there are a large number of optional areas, that is not necessary to get to the credits, where species of Pokémon that cannot be found elsewhere appear or only by searching the Great Dungeons. A tip in this regard is to use the Challenge Seeker, a tool obtained from Dawn / Lucas on Route 207. Thanks to it you will find out if there are any Trainers in an area that you have not yet challenged, as well as those who want a rematch.
