Completing the Pokedex is always one of the most exciting challenges in the franchise, and the early generations make this task much more achievable with their smaller dex sizes. Pokemon FireRed and LeafGreen's Kanto Pokedex consists of the original 150 Pokemon, but players who defeat the Elite Four and become Champion will gain access to the National Dex, allowing them to obtain all 386 Pokemon available in Gen 3. The problem with Pokemon FireRed and LeafGreen's Switch release is that 166 of these critters will likely be unobtainable for the foreseeable future, meaning completing the National Dex will be impossible.
