region's Pokédex (Generation I)
Kanto region's Pokédex (Generation III)
This is a list of Pokémon in the order dictated by the Kanto regional Pokédex, meaning that the starter Pokémon from Kanto will appear first, followed by Pokémon native to the Kanto region.
This Pokédex, which was introduced in Generation I, is the first regional Pokédex. The numbering in this Pokédex would serve as the basis for the official listing of all Pokémon introduced, with subsequent generations' Pokémon being added on to the end, with the name of "Old Pokédex" in Generation II and then the "National Pokédex" ever since, starting with Generation III. For more info on this expanded number listing see this list.
In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, the Kanto Pokédex listing was expanded to include Meltan and Melmetal.
Changes between generations
With the introduction of Steel-type in Generation II, Magnemite and Magneton had their types changed from being pure Electric-type to Electric/Steel-types. This change was reflected in Pokémon FireRed and LeafGreen.
With the introduction of Fairy-type in Generation VI, Clefairy, Clefable, Jigglypuff, Wigglytuff, and Mr. Mime had their types changed from pure Normal-type (Clefairy, Clefable, Jigglypuff, and Wigglytuff) and pure Psychic-types (Mr. Mime) to pure Fairy, Normal/Fairy, and Psychic/Fairy respectively. This change was reflected in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!.
Additionally, Meltan and Melmetal were added to the Pokédex, expanding the total to 153 Pokémon. Alolan forms were also added to the Pokédex but are counted as forms of the original Kanto versions rather than a separate entry.
