By completing the main storyline missions of the game, you'll be able to collect 157 entries in the Browser. The Challenges are available as earlier as entering Summerland and Ringtown but to get all 25 entries in them it's recommended to wait until post game. There are three Pokémon only available through the Ranger Net missions who don't need to be captured to receive the Certificate of Completion. The remaining 28 entries are available via post-game content.
Special Missions[edit]
After the credits roll, you'll be able to proceed to the Special Missions and capture eight new Pokémon.
Challenges[edit]
Some Pokémon are locked behind the high scores of the challenges or they only appear in the challenges after the credits roll. Start with the Capture Arena Challenge as you need to get 50,000 points to unlock Fearow in the Grassland Challenge. Pokémon captured in the Arena will not be registered in the Browser. Those captured through the Grassland and Marine Sea challenges will give you access to 25 new Pokémon.
The Regi Trio[edit]
Seven more Pokémon are available while Finding the Regi Trio.
Finding the missing entries[edit]
Another thirteen Pokémon will be available by Finding the strays.

Special Pokémon[edit]
