- There are 104 new Pokemon. Galar forms are in, like the other leak implied with Meowth. "Sirfetch'd" is actually a Galar form and does not use that name, but the leaker may have called it that to paint a picture of its design. Its leek gets treated more like a cane as well as a color swap to black and white.
- This time, representation is scattered among all past region Pokemon unlike with Alolan Pokemon just being Kanto. Some examples will be the Gulpin line (they'll look more like sweets) and the Dwebble line (They'll be much more grassy and green).
- The majority of Kanto Pokemon will return. Strong representation from each other regions as well (though less than Kanto), totaling to a regional dex size of over 600+ Pokemon to make up for not every Pokemon being in the game. Many will only be acquirable through events and Max Raid Battles that get rotated around.
