If I were to log every available Pokemon into every Pokemon game to date, how many Pokedex entries would there be?

Question

So if I logged in all the Pokemon in Red, Blue & Yellow that would make 353 Pokedex entries but how much would it be with all other games included?

Answer 1

Main Series Games

Red, Green (JP), Blue, Yellow = 453
Gold, Silver, Crystal = 753
Ruby, Sapphire, Emerald = 1158
FireRed and LeafGreen = 772
Diamond, Pearl and Platinum = 1479
HeartGold and SoulSilver = 986
Black and White = 1298
Black and White 2 = 1298
X and Y = 1436
Omega Ruby and Alpha Sapphire = 1436

Add that up and that makes... 11,069 entries to complete!
These are for the National Pokedex entries.

If you want me to do the spin-offs I hate you. I'll do them.

Hope I helped. :)
