Pokeetong Red and Green Versions

Pokémon Red Version (Japanese: ポケットモンスター Pocket Monsters: Red) and Pokémon Green Version (Japanese: ポケットモンスター Pocket Monsters: Green) were the first Pokémon games ever released to the public, in Japan on February 27, 1996. Introducing the gameplay concepts that went on to provide the standard for games in the core series games, these games were eventually localized and released worldwide as, using a combination of the engine from the Japanese and the obtainable Pokémon from Red and Green. Much as would become standard, Red and Green were later joined by a solitary version, the aforementioned, which slightly improved upon their features and provided the code for the international releases (Red and Blue), and eventually , a second solitary version based on the.

In 1999, the sequels to these games, were released with the Game Boy Color in mind but remaining playable on the original Game Boy like Red and Green. In 2004, the remakes of these games were released for the Game Boy Advance as.

Plot
Red and Green begins the Pokémon series in the region of Kanto, where players play the role of a ten-year-old Pokémon Trainer just starting off a journey from their home of Pallet Town, on the same day as their. After obtaining a starter Pokémon (a choice of the,  , or  ) from Professor Oak, the local authority on Pokémon (and with their rival choosing the Pokémon whose type weakens that of the player), players would journey across the region, defeating the eight Gym Leaders: Brock, Misty, Lt. Surge, Erika, Koga, Sabrina, Blaine, and Giovanni. After all eight have been defeated, the player goes on to challenge the Elite Four, Lorelei, Bruno, Agatha, and Lance, and finally, in their last battle, the current Champion,.

Along the way, Trainers will encounter the evil Team Rocket, a group of criminals that seek to exploit Pokémon, rather than train them as friends and partners, and must defeat them to put a stop to their actions. The rival will also continuously harass the player, challenging him to over and over, with an increasingly powerful team. As the player's own Pokémon become more powerful, they draw ever closer to Indigo Plateau.

Connectivity
The two games introduced the ability to allow players to trade Pokémon between two cartridges using a Game Boy link cable. To take fullest advantage of this feature, several Pokémon are exclusive to each game of the pair, making it required that a player trade with others in order to complete their Pokédex. The link cable also makes possible battles with another player, allowing one to pit their against equals when their Pokémon are as powerful as they can be, at level 100. Trades done between Pokémon games in different languages are impossible in this generation, and will always result in corruption if it is attempted. This is due to the fact that the games can't automatically translate the Pokémon as there isn't enough room on either cartridge for all of the text in so many languages (a feature that would later become possible). If a battle between two different region games is to be attempted, the battle would simply not work, with the save file left intact.

Gyms
As would become the case for each Pokémon game in the core series to come, there are eight Gyms in Kanto, each with their own type affiliation. The Gym Leaders are: Brock (Rock) at Pewter City, Misty (Water) at Cerulean City, Lt. Surge (Electric) at Vermilion City, Erika (Grass) at Celadon City, Koga (Poison) at Fuchsia City, Sabrina (Psychic) at Saffron City, Blaine (Fire) at Cinnabar Island, and Giovanni (Ground) at Viridian City.

Elite Four
Another standard established by Red and Green, the goal for players, the Elite Four, is located at Indigo Plateau. The Elite Trainers are Lorelei (Ice), Bruno (Fighting), Agatha (Ghost), and Lance (Dragon). The Pokémon Champion is the rival,, who does not specialize in any one type.

Pokémon
Each game contains pre-recorded data on 151 different species of Pokémon, including, a Pokémon even Nintendo was not aware of initially. However, not all Pokémon are available to the player, regardless of version; trades must occur between players in order to complete their Pokédex without the use of cheats or glitches. In addition, Mew is not normally obtainable in either game; the only legitimate way to obtain Mew is through a Nintendo sponsored event.

Version-exclusive Pokémon
The following Pokémon are only obtainable in one game of this pair. In order to obtain Pokémon exclusive to the other game of this pair, they must be traded either from that game or from another compatible game of Generation I or Generation II which has that Pokémon available. {| style="margin:auto" {| class="roundy" style="margin:auto; background: #; border: 5px solid #;" !
