HeartGold & SoulSilver Pokédex

The native Johto Pokédex in Pokémon HeartGold & SoulSilver is almost identical to the original games. Strangely, it adds the evolutions Yanmega, Ambipom, Lickilicky, Tangrowth and Mamoswine, but not some other evolutions (e.g. Electivire) or baby Pokémon (e.g. Wynaut).

As usual, later you obtain a National Dex with the entire set of Pokémon in the order they were added.
