[Brilliant Diamond & Shining Pearl] Additional Pokemon

they should add sylveon and some unova/kalos/alola and also galar pokemon

just some though

It's hard to say really. I mean if the ORAS version of the PokeDex is any indication, then it's definitely a possibility. Probopass wasn't originally in the original because it didn't exist at that time. The Eevee line is quite popular with the fanbase so they really could just throw in the additional evolution. Would I personally mind it? Not really, I think it would be a good marketing move for sure seeing how widely popular Sylveon in particular is. The PokDex more certainly needs more Fire-types, because we can't have Flint running Steelix and Driftblim in 2021.

Every pokemon at least until Gen 6 =D
