List of cross-generational evolutionary lines

This is a list of Pokémon evolutionary lines including Evolutions from different generations. For example, Pichu (a Generation II Pokémon) evolves into Pikachu (a Generation I Pokémon). A few of these Pokémon, as a result of new Evolutions, become a part of evolutionary lines with branched Evolutions.

Starting with Generation VII, several old Pokémon lines were modified by introducing regional forms of older Pokémon adapted for life in different regions. While regional forms of the same line are always related via breeding, lines entirely consisting of regional variant forms of the exact same species are not considered to be in the scope of this page.

Entries in each section are listed in ascending order based on the lowest National Pokédex number among the members of the evolutionary line.

Common stage and new species

These evolutionary lines have received actual new Pokémon species introduced at some point after the debut of the earliest members that either evolve into or evolve from preexisting stages. In other words, these lines have at least one instance where a Pokémon can evolve into a stage introduced in a different generation and the two species in question also debut in different generations.

New species only

These lines consist of evolutionary lines with regional variant forms that do not share common unevolved stage with other forms of the species involved and do not have stages introduced in different generations on each line. However, certain Pokémon species will only evolve from a specific regional form and, therefore, have no counterpart. As such, these cases do not have cross-generational Evolutions in the sense where a specific Pokémon can evolve into a stage introduced in a different generation, but rather, these lines have member species introduced in different generations.

Trivia

• Pokémon which evolve into a Pokémon of a previous generation, instead of from it, are always baby Pokémon.
  • Conversely, the only baby Pokémon introduced alongside their evolved form are Togepi, Riolu, and Toxel; the rest were introduced in generations after their evolved form was.
• Generation IV introduced the most evolutionary relatives to Pokémon from previous generations, with 29, and Generation VI introduced the fewest evolutionary relatives to Pokémon from previous generations, with only one, Sylveon.
  • Generation V did not introduce any evolutionary relative to Pokémon from previous generations. Generation VII did not introduce any new species as relative to Pokémon from previous generations.
  • Generation VIII introduced the most regional form-exclusive Evolutions, with eight (six introduced in Pokémon Sword and Shield and two introduced in Pokémon Legends: Arceus, and Generation IX introduced the fewest regional form-exclusive Evolutions, with only one, Clodsire (from the Wooper line).
• Some cross-generational evolutionary lines have unique distinctions:
  • Porygon is the only Pokémon to have an Evolution introduced in a later generation that was later able to evolve once again.
  • The Tyrogue line is the only one to include Pokémon (Hitmonlee and Hitmonchan) that were introduced as not being related to each other in an evolutionary line.
  • The Scyther line is the only branched Evolution line to have each member species introduced in a different generation.
  • The Chansey, Mr. Mime, Electabuzz, Magmar, and Porygon lines are the only lines to have each member of a three-stage evolutionary line introduced in a different generation.
  • Roselia is the only Pokémon to have both a pre-Evolution and an Evolution (Budew and Roserade, respectively) introduced in the same generation outside its debut generation.
  • The Pikachu and Mr. Mime lines are the only lines to have received both new member species and new forms of existing member species that share common unevolved state with other forms.
  • The Pawniard line is the only line introduced in Generation V in which the Evolution does not evolve from a regional form (unless White-Striped Basculin is not considered a regional form).
  • The Applin and Mr. Mime lines are the only branched evolutionary lines that branches into both two-stage and three-stage lines.
