Game Freak hasn't confirmed all of the Pokémon that will appear in "Sword and Shield," but players with early access to the game have explored the game's code to see exactly which Pokémon made the cut.
While the list of Pokémon is literally hundreds of names long, dedicated players made a helpful grid to make it easy to see if your favorite Pokémon can be found in "Pokémon Sword and Shield." To avoid spoiling the surprise for fans looking forward to the games, and because the grid is huge, I won't share it here, but you can check it out on your own.
If you do take a peek at the grid, here's how to read it: Pokémon in red boxes won't appear in "Sword and Shield," while Pokémon in green boxes will. Pokémon in pink or purple have a new form or evolution, while Pokémon in yellow are in the game's code but won't appear normally. So it's possible that favorites like Bulbasaur and Squirtle could return during special events in the future.
