What Pokémon are catchable on Route 1 in Pokémon: Ash Grey?
I decided to go ahead and put it to the test. I ran around and battled 100 Pokémon on Route 1, and recorded what they were. Although my sample size was relatively small, I think this gives a good indication of what Pokémon are available.
Route 1
- Pidgey: 36
- Spearow: 32
- Ratatta: 29
- Sandshrew: 3
I found Pidgey, Spearow, Ratatta and Sandshrew. I also found a Mankey.
I sped up the game via an emulator and did 1000000 wild encounters. I was able to encounter Pidgey, Ratatta, Spearow, Sandshrew and Mankey.
There is nothing else in the area.
