PKMN Legends: Z-A Official Starter Discussion

Big left swing here. I think game freak potential told use the starter in scarlet and violet. When you unlock the starters in the terrarium it states a starter pokemon.

1. Grookey
2. Litten
3. Piplup
4. No
5. Frokie of course.

With the unlock theory the fourth biome it states charmander which could be for a new Charizard mega or a battle bind form.
