No. It's part of the Sinnoh dex.
You have to get the national dex before you can battle them. You get the national dex by having at least 60 Pokémon registrated in your regular dex and talking to Oak.
From eterna cities forest and that huanted house( after national dex)
Gengar i think Ceffa is the 99th Pokemon in the sinnoh dex and kingler is the 99th in the national dex pickles are awesome
No, you don't need the National Dex to evolve Haunter in Pokemon SoulSilver. You just need to trade it with a friend then trade it back. Then, you have a Gengar!
You don't battle Prof. Oak.
You become the champion by beating Cynthia and you have to battle everyone in the game to get the national dex
it is Uxie before the national dex and Moltres after you get the national dex
You don't get the national dex until you beat the elite four and yes, you have to have the national dex to get him because entei is a distant legendary you can only find in the early games. So you need the national dex, but not before you beat the elite four.
You have to beat dawn in a Pokemon battle.
