A list of Franchise/{{Pokemon}} who debuted in ''VideoGame/PokemonRubyAndSapphire'', and their relatives. Introducing 135 Pokémon, of which only 2 are related to older Generations, this generation was the second largest until Generation V came around. 7 Pokémon related to this generation were introduced in [[VideoGame/PokemonDiamondAndPearl Generation IV]], bringing the grand total to 140. Seeing as in the first games of this generation, most old Pokémon were absent, numerous Expies were introduced, and so several themes such as Fossils were brought back. This generation was also the first to diverge from the [[PowerTrio trio]]-uber-event dynamic of legendaries (although Lugia and Ho-Oh were a borderline break), by making the version mascots another [[PowerTrio trio]], and introducing a pair of legends with no equivalent in older generations.
