- This article is about the HeartGold and SoulSilver counterpart. For the Gold, Silver, and Crystal Pokédex, see List of Pokémon by new Pokédex number.
The original new Pokédex was dropped for Pokémon HeartGold and SoulSilver, which alter the Pokémon Gold, Silver, and Crystal order of the Johto Pokédex slightly, moving some Pokémon down the list to add a select few Pokémon that evolve from Generation I and Generation II Pokémon by the method of learning a move (specifically Tangrowth, Mamoswine, Lickilicky, Yanmega, and Ambipom). However, up to #101 (Yanma), the order is the same as that of the new Pokédex, after which it diverges starting with #102 (Yanmega).
List of Pokémon by Johto Pokédex number
#001 - #051 Chikorita - Arbok
#052 - #100 Dunsparce - Nidoking
#101 - #150 Yanma - Tauros

#202 - #256 Mantine - Celebi
- The five Pokémon added to the new Pokédex to create this listing all evolve from their previous forms (which were included in the new Pokédex) when leveled up knowing a certain move. All other Pokémon related to Pokémon found in this Pokédex require an item to evolve from their Johto Pokédex relative.
