The following list details the 151 Pokémon of Generation I in order of their National Pokédex number. The first Pokémon, Bulbasaur, is number 001 and the last, Mew, is number 151. Alternate forms that result in type changes are included for convenience. Mega evolutions and regional forms are included on the pages for the generation in which they were introduced. MissingNo., a glitch, is also on this list.

Design and development

The majority of Pokémon in Generation I had relatively simple designs and were highly analogous to real-life creatures including but not limited to: Pidgey (a pigeon), Krabby (a crab), Rattata (a rat), Ekans (a snake), Arbok (a cobra), Seel (a seal), and Dewgong (a dugong). Many Pokémon in the original games served as the base for repeating concepts later in the series.^[1]
