>>14497471Like I said, that's pretty much what the Pokedex is for. Once you see a Pokemon once, you'll be able to check the Pokedex and see all its possible locations. It's a really convenient feature that no one ever uses because why use what's actually implemented in the game when you could just check online for it?
Why do you people ruin things for yourselves like this? Don't you remember back when you first played Red and/or Blue and you fought a trainer who had a really cool Pokemon you'd never seen before so immediately after you beat them, you checked the Pokedex and looked up its entry?
