List of Pokmon by evolution family

From Bulbapedia, the community-driven Pokémon encyclopedia.

This is a list of Pokémon by their evolution family. That is, it is a list of Pokémon in their National Pokédex order, but it also includes later-released evolutions and pre-evolutions closer to the first Pokémon in their family to be released. This means that Pichu will appear before Pikachu, instead of at its National Pokédex position of 172, and Magby and Magmortar will appear next to Magmar. Evolution families are named by their basic evolutionary form. For example, although Azurill is the lowest Pokémon in its evolutionary line, it is still known as the Marill family, because Marill was released first.

The methods of evolution listed include all means of inducing a Pokémon's evolution in the core series games, Pokémon Colosseum, and Pokémon XD. The first method listed is the first that was available. In some games, some methods may not be available (such as Eevee's evolution to Espeon or Umbreon in Pokémon FireRed and LeafGreen) or practical (such as Feebas, who will always evolve if its Beauty is high enough, but its Beauty cannot be affected in all games).

In total, there are 531 evolutionary families as of Generation IX.

Trivia

Professor Rowan is said in the games to have studied Pokémon Evolution and determined that 90% of all Pokémon are related in some way by evolution. As of Generation IX, with 201 Pokémon out of 1025 total not evolving, this is slightly inaccurate, as about 80% of all Pokémon undergo at least one evolution before being fully evolved. Excluding the 90 legendaries and mythicals (121 out of 929) it's around 87%. In previous generations:
- 25 out of 151 Pokémon did not evolve in Generation I, meaning 83% of all Pokémon undergo at least one evolution. Excluding the 5 legendaries and mythicals (20 out of 146) it's around 88.5%.
- 43 out of 251 Pokémon did not evolve in Generation II, meaning 83% of all Pokémon undergo at least one evolution. Excluding the 11 legendaries and mythicals (32 out of 240) it's around 87%.
- 73 out of 386 Pokémon did not evolve in Generation III, meaning 81% of all Pokémon undergo at least one evolution. Excluding the 21 legendaries and mythicals (52 out of 365) it's around 86%.
- 77 out of 493 Pokémon did not evolve in Generation IV, meaning 84% of all Pokémon undergo at least one evolution. Excluding the 35 legendaries and mythicals (42 out of 458) it's around 91%.
- 104 out of 649 Pokémon did not evolve in Generation V, meaning 84% of all Pokémon undergo at least one evolution. Excluding the 48 legendaries and mythicals (56 out of 601) it's around 91%.
- 115 out of 721 Pokémon did not evolve in Generation VI, meaning 84% of all Pokémon undergo at least one evolution. Excluding the 54 legendaries and mythicals (61 out of 667) it's around 91%.
- 146 out of 809 Pokémon did not evolve in Generation VII, meaning 82% of all Pokémon undergo at least one evolution. Excluding the 70 legendaries and mythicals (84 out of 739) it's around 89%.
- 166 out of 905 Pokémon did not evolve in Generation VIII, meaning 81% of all Pokémon undergo at least one evolution. Excluding the 82 legendaries and mythicals (94 out of 823) it's around 89%.
By far, a plurality of three-stage evolution families were introduced in Generation I, with 29 such families having their roots there (though not necessarily their most unevolved or most evolved forms). Because of branched evolution, 31 of the second-evolution Pokémon can count themselves as members of a Generation I evolution family. Generation V has the second most, with 20 three-stage families (none due to branching). Generation III has the next most, with 16 three-stage families that end in 18 Pokémon (again due to branching). Generations II, VIII, VI, VII, and IV have the least, with only ten, nine, eight, eight, and six families, respectively, that end in a third member.
- Generation V, however, has introduced the most original three-stage evolutions, as many of the three stage-evolutions stemming from Generation I include Pokémon not introduced in the same generation as their evolutionary relatives.
Not including alternate forms, or the letters of Unown, nine Pokémon families consist of more then three Pokémon. They are the Nidoran, Oddish, Poliwag, Tyrogue, Eevee, Wurmple, Ralts, Cosmog, and Applin families.
