Some players remember discovering Pokémon for the first time on the Nintendo Game Boy, while newer fans enjoy Gen 1 because many of its species have become permanent fixtures of the franchise. From the very first entry, Bulbasaur (#001), to the elusive mythical Pokémon Mew (#151), the Kanto Pokédex contains a timeless variety of designs, types, abilities, and evolution lines.

What Is Gen 1 Pokémon?
The term Gen 1 Pokémon refers to the first generation of Pokémon introduced in the original games. This generation contains 151 Pokémon, numbered sequentially from #001 Bulbasaur through #151 Mew in the official Pokédex index.
The first generation is set primarily in the Kanto region, which was inspired by the real-world Kantō region of Japan. The original games introduced players to a rich fictional world where humans and Pokémon coexisted, trained, competed in Gym battles, and traveled across interconnected towns, forests, caves, and routes.
First released in Japan in 1996, Pokémon Red and Green introduced the core RPG gameplay that would become a global standard. Pokémon Blue followed shortly after as an enhanced version, while Pokémon Yellow: Special Pikachu Edition later offered a unique playthrough inspired by the animated TV series.
One of the most impressive aspects of Gen 1 is how much species variety was achieved despite memory constraints. Players could choose between Grass-type Bulbasaur, Fire-type Charmander, and Water-type Squirtle as their starter Pokémon before assembling a diverse team to conquer the Pokémon League.
Data for all 151 Kanto Pokémon is preserved today in open database initiatives like PokéAPI, allowing developers and fans to inspect base stats, sprite artwork, and move lists.
