Revision as of 01:07, 16 February 2013 by Miles of SmashWiki(talk | contribs)(→Eeveelutions: feel free to take this out or adjust the formatting of how I put it in, but as it's a confirmed cross-gen evolution it should be here somehow.)
A few of these Pokémon, as a result of new evolutions, become a part of evolutionary families with branched evolutions. Those Pokémon which evolve into a Pokémon of a previous generation, instead of from it, are specifically baby Pokémon.
Generation IV introduced the most evolutionary relatives to Pokémon from previous generations, numbering 29; Generation II introduced 18 and Generation III only 2.
Generation V introduces none, the only generation other than Generation I which does not.
