Whether she is chosen to be the player character or not, this new character will still appear in the game. Kris, despite being the female counterpart of Crystal's player character, is not included as the female player character, with a new character instead taking her place. Like how FireRed and LeafGreen could link up with Ruby, Sapphire, and Emerald to complete the Pokédex by trading regionally exclusive Pokémon, HeartGold and SoulSilver can link up with Diamond, Pearl, and Platinum to obtain Pokémon unavailable in Johto and Kanto (such as the Sinnoh starters) and vice versa. Some aspects exclusive to Crystal are also included. While the games feature several expansions in key areas, the overall plot follows the same direction as the original Gold and Silver. Much like how Pokémon FireRed and LeafGreen revisited the Generation I story of Kanto, HeartGold and SoulSilver retell the story of Johto, with the player's starting town being New Bark Town. Pokémon HeartGold Version (Japanese: ポケットモンスターハートゴールド Pocket Monsters HeartGold) and Pokémon SoulSilver Version (Japanese: ポケットモンスターソウルシルバー Pocket Monsters SoulSilver) are paired Generation IV remakes of the Generation II games Pokémon Gold and Silver.
