The first generation of Pokémon games, known among older fans as the color generation due to the names of the versions released, is the initial set of four Pokémon games released.
Beginning with Pokémon Red and Green, and later joined by third version Blue and special edition Yellow in Japan, the Generation I games were developed beginning as early as 1990 from an idea that Satoshi Tajiri had thought of and pitched to Nintendo with the help of Shigeru Miyamoto. The inspiration for many of the key mechanics introduced in this generation came from Tajiri's childhood interest in bug collecting, with the trading system between two Game Boys being thought of when he imagined a caterpillar crawling across the link cable between two systems.
This generation was localized into English, with initial attempts to keep the Pocket Monsters name for international use blocked due to the Monster in my Pocket franchise leading to the release as "Pokémon". Further alterations made in the localization included the combination of Red, Green, and Blue into the English versions of Pokémon Red and Blue, using Red and Green's wild Pokémon encounter lists but Blue's slightly improved graphics. Despite this, the simultaneous release of the games and anime led to an almost-overnight surge in popularity that raised some parental concern, often dubious, and cemented the Pokémon franchise firmly as a Nintendo mainstay alongside Super Mario and The Legend of Zelda.
Two battle arena games were released in this generation: the mostly-incomplete Pokémon Stadium 0, which went unreleased outside of Japan and only allowed use of 42 Pokémon, and the improved Pokémon Stadium, which featured several special battle modes and a Gym Leader Castle where players could take their fully-trained teams for matches against the Kanto Gym Leaders, Elite Four, and Champion.
The storyline of the Kanto region is contemporaneous with the Hoenn story of Generation III, as revealed by details in both the Hoenn-based games as well as the later remakes of Generation I. The storylines of the Generation II and Generation IV games occur three years after this generation, with details about this link explicitly noted throughout the Johto-based games.
Generation I introduced the key Pokémon gameplay elements which have remained to this day, as well as a system of game releases now considered by fans to be the "standard formula". While many of the features enjoyed in the more recent generations are later additions to the series, the following have their origins in Generation I:
- The player has a party of up to six Pokémon with them, which can be used in battle against opponent Pokémon Trainers or wild Pokémon.
- A PC-based Pokémon storage system, made up of 12 boxes of 20 Pokémon each and developed by Bill, a Pokémaniac, is available to store reserve Pokémon not in the party (up to 240 total).
- 151 species of Pokémon, with many related to each other by way of evolution.
- A complex battle system, including:
- Five stats, HP, Attack, Defense, Speed, and Special, which each Pokémon has. Different Pokémon have different stats, even among the same species.
- 15 different elemental types, which each Pokémon species has inherent to itself.
- 165 unique moves, restricted to four per Pokémon, each with its own elemental type, accuracy, and base power.
- The Pokémon League challenge, consisting of Kanto's eight Pokémon Gyms, scattered across the region with each specializing in a different type, and the Elite Four and Pokémon Champion, awaiting challengers at the Indigo Plateau.
- A linked trade and battle system between two Game Boy systems, allowing players to exchange Pokémon they caught for a Pokémon owned by another person or to battle against each other to test their skills.

Generation I introduced the first region to the Pokémon series, which, though unnamed in the original English games, is named in Japanese as Kanto, after the region of Japan it is based on. The name has since passed into English, first being used in Super Smash Bros., and subsequently being noted in all games since.
At the outset of the player's journey, he will have no Pokémon on hand, and venturing outside of Pallet Town is impossible, as Professor Oak will stop him and bring him back to his lab, where three Pokémon await both the player and his rival.
The starters of the Kanto region began the three-type trio that is still followed in Generation IV of Grass, Fire, Water, with the player's choice being of Bulbasaur, Charmander, or Squirtle. Much as in later generations as well, the rival will choose whichever of the three has the type that is super effective against that of the player.
The choice of a starter can make the beginning few Gyms change in difficulty, but does not affect much in the long run aside from the rival's party. Bulbasaur is known by many to be the easiest to start with, as its Grass-type weakens the first two Gyms and resists the attacks of the third. Squirtle is known as the second easiest, as Water-types also weaken the first Gym, however, it can prove difficult mid-game if the player has not caught a Pokémon that can resist the later Gyms. Charmander is widely regarded as the hardest of the trio, as Fire-type moves do little damage against the first Gym's Pokémon, and there are few opportunities for capture of a Pokémon that can counterbalance its weaknesses against the first several Gyms.
In Pokémon Yellow, instead of the normal trio found in Red, Green, and Blue, players can only start with the Template:Type2 Pikachu, which likewise has difficulty with the first Gym. The rival will take Oak's Eevee and evolve it into one of its three stone-based evolutions depending on the results of the player's battles against him.
The eight Kanto Gym Leaders each specialize in a different type of Pokémon. Each gives out a badge and a TM on their defeat.
Discussion of Generation I
When the games were first released, despite their inferior graphics and sound compared to other games of the time, they were revolutionary, firmly rooting the Pokémon series as one of Nintendo's mainstays alongside Mario and The Legend of Zelda.
Throughout the four generations so far, Pokémon has continued to build on the successes of Generation I's system, while addressing the drawbacks and errors made in the development of the games. Many of the Pokémon world's standards were set in the first generation, including the first five HMs, all of which, with the exception of Flash, remain tools required for the game's completion in the most recent games.
Not only were gameplay aspects of the world set in Generation I, but also the storyline aspects. Each region since Kanto has had a local Pokémon Professor named after a tree who gives the player a starter Pokémon, an evil team whose goal is to rule the world, and many other things that are now integral to being a main series game.
The games proved popular enough that, eight years after their original release, they received remakes in the form of Pokémon FireRed and LeafGreen, as the original versions are incompatible with Generation III and onward.
- Excluding FireRed and LeafGreen, as they are remakes, Generation I is the only generation so far whose mascots are non-legendary Pokémon.
- As far as release dates go, Generation I is the shortest generation in North America, partly due to the fact that Red and Blue were not released until 1998, while in Japan, they were released in 1996, and their successors, Gold and Silver, were released closer together, in 1999 in Japan and 2000 in North America. As the rest of the world's releases are more similar to the North American releases than the Japanese releases, it is also the shortest generation worldwide.
- Generation I has the most amount of Glitch Pokémon which are known to be obtainable without the use of an external device.
- Generation I has the most extra space in the Pokémon storage system if the player captures one of each Pokémon, with 240 spots available for 151 Pokémon, leaving 89 extra spots.
- Generation I is the only generation not to feature the paired version's mascots on the title screen, but it does include their first evolution stage.
