List of cross-generational references

The four generations of Pokémon games, taking place in the same universe, have had multiple references to each other. Not only do the games reference their same-generation counterparts (with the player's default name being the version played and the rival's being the counterpart version in the first two generations), but games released later in the series typically will feature references to events of past generations.

Please note, of course, that this does not include Pokémon. While Pokémon released in previous generations will always appear, they are not a reference to the generation itself.

List of references

Generation II

To Generation I

• Not only is the Kanto region a playable area during the games, but several of the events of Generation I are spoken of as having happened three years previous. Many characters also reappear because of this, though some of them undergo design changes.
• Red, the player character of the first games, is found training in Mt. Silver and can be battled.
• Blue, the rival character of the first games, has become the Gym Leader of Viridian City. His team is based on the Pokémon he used in the final battle in Pokémon Red and Blue.
• A man in the Violet City Pokémon Center states that the former Team Rocket was broken up by a "young kid."
• The parents of the Copycat in Saffron City mention that her Clefairy Doll was given to her by a boy three years before.
• The Berserk Gene, a held item, is found near the former entrance of the now-collapsed Cerulean Cave, where Mewtwo once hid.
• There is a Pokémon doll of a Surfing Pikachu available to decorate the room, which references the special minigame in Pokémon Yellow.
• A man in Cerulean City says there used to be a cave near the city with powerful Pokémon.
• If the player checks the poster in the Rocket Game Corner, the player will be informed that there's nothing there, referring to the secret switch under the poster in Generation I.

Generation III

To Generation I

• Brawly is said to have once trained alongside Bruno, who is a member of Kanto's Elite Four.
• The Oceanic Museum in Slateport City has two water samples, one of which is from Kanto. Its background music theme is also an arrangement of the S.S. Anne theme.
• On Faraway Island, a series of smudged messages, which may have been left by Mr. Fuji, appear on a signpost.
• A boy in Lilycove City says that he and his family came from the Kanto region before he asks if there are any Pokémon found only in the Hoenn region.

To Generation II

• In Pokémon Ruby and Sapphire, the player-controlled character of Pokémon Ruby, Sapphire, and Emerald is said to have moved at the beginning of the game with his/her family from the Johto region, the main setting of the Generation II games. In Pokémon Emerald the character who said this instead states that the player character's family moved there from a faraway place.
• The beta versions of Pokémon Ruby and Sapphire contained remastered versions of the themes played on Routes 38 and 39, Team Rocket encounter, Legendary beasts' battle, and Saffron City.
• The Oceanic Museum in Slateport City has two water samples, one of which is from Johto.
• A man in Mt. Moon says that Brock sometimes helps excavate fossils there. This explains how he acquires the Kabutops and Omastar which he uses in the second generation of games.
• At the Cerulean Cape, a dame says Misty has high hopes about the location, which is known as a famous dating spot. In the second generation of games, she is first encountered there with an unknown male character.
• Janine, Koga's daughter and future Leader of Fuchsia Gym, appears in Fuchsia City, and tells the player that she is training to use Poison Pokémon like her father. She is misnamed as Charine in the English translation of FireRed and LeafGreen, however.
• The branch of Team Rocket in the Sevii Islands seems to be the same branch which attempted to revive Team Rocket during Generation II, with plans to use magnetic waves to evolve Pokémon. Their lead scientist also tells that Giovanni's child has red hair, a reference to Silver.
• One of Professor Oak's assistants will state that he is to get a radio show sometime in the near future.
• Celio mentions that some members of Bill's family live in Goldenrod City.
• A woman on Boon Island in Bruno's section of the Fame Checker mentions the Rage Candy Bar.
• Whitney, Jasmine and Pryce lookalikes appear as audience members in Contests.
• The man who digs Three Isle Path and gives the player a Nugget says that he'd like to buy a house in Kanto. He likely is the same person who gives away a Nugget in Generation II in his house on Route 2.
• The themes used on the Sevii Islands are remastered versions of the routes around Mahogany Town as well as remastered versions of Violet/Olivine City and Azalea Town/Blackthorn City.

Generation IV

To Generation I

• Professor Rowan is said to have developed the Sinnoh Pokédex with help from a Pokémon professor from Kanto.
• Professor Oak himself comes to Sinnoh to give the player the National Pokédex, and can always be found in a house in Eterna City thereafter. He gives the player an Up-Grade, which was sent to Oak by his acquaintance from Kanto.
• In the gatehouse east of Canalave City is a guard who complains that he is thirsty, like the guards in Kanto who will allow the player to enter Saffron City if they are brought a drink. Unlike those guards, however, this one does not do anything if brought a drink.
• One of the Elite Four, Bertha, shares a similar name (in Japanese and English) and design to Agatha. It is possible they are related, or that Bertha was at least modeled after Agatha.
• Black Belt Eddie from Victory Road mentions that he trained in Fighting Dojo at Saffron.
• In Amity Square, some Pokémon may be let out out of their Poké Ball to follow their Trainer around. One of the few available is Pikachu, which did the same (however, throughout the game) in Pokémon Yellow.
• Bebe's buddy Bill is mentioned to have developed the basic storage system.
• Part of the Veilstone Game Corner music is a techno remix of the Rocket Game Corner music.
• One of Lucas's alternate names was Ash in the English versions of Pokémon Diamond and Pearl. This is one of the default names of Red in the games Pokémon Red, Blue, and Yellow, FireRed and LeafGreen. It may even be a reference to the anime's main character.

Wallpaper

• As a direct tribute to the original games, one of the wallpapers has been designed to resemble the design of the routes of the first games, complete with the graphics and sprites when the games are played on the Game Boy. The wallpaper showcases typical features like both types of fences, low and high grass, normal ground, a sign and a house.
• As Pokémon HeartGold and SoulSilver are remakes of Pokémon Gold and Silver, the references present in the original games to Generation I return.
• During a special Celebi event, the character will, in fact, travel in time back to shortly after Red has defeated Giovanni. Giovanni tells his son that he has decided to disband Team Rocket. Afterwards, he will run towards the Johto region and is found in a cave. When the player has defeated him, he will make a remark that the player reminds him of the boy that made him disband the team in the first place.

To Generation II

• A news report of a red Gyarados begins Pokémon Diamond and Pearl. The cameraman who filmed the documentary appears at the Survival Area.

• Dragon Tamer Hayden on Route 224 mentions that he left the Dragon's Den several years ago.
• The Poké Ball design on the floor of the Sinnoh Pokémon Centers is colored gold and silver. Park Balls are also colored gold and silver, and the normally black stripe in the middle is actually a light blue, crystal-like color.
• Dragon Tamer Geoffrey on Route 225 mentions a Dragon Tamer Champion.
• The Eevee which Bebe gives to the player was obtained originally from her friend in Johto.
• Cynthia, who somehow was able to obtain it (possibly from Jasmine, since she is in Sinnoh), gives the SecretPotion, the medicine from Cianwood City that cured Amphy in Generation II, to the player to cure the group of Psyduck blocking Route 210.
• In Stargazer Colosseum in Pokémon Battle Revolution, some of the Pokémon in the last battle depend on which game is linked to the Wii. If Diamond is linked, one of the Pokémon is Ho-Oh, Gold's version mascot, and if Pearl is linked, one of the Pokémon is Lugia, Silver's version mascot.
• When a Template:Shiny2 Clefairy appears during a slot game in Veilstone Game Corner, a remixed version of Mt. Moon Square music from Gold, Silver, and Crystal is played.

• A Swimmer south of the Valor Lakefront says she would like to vacation in Hoenn because it has more routes on which to Surf.
• A woman west of Pastoria City used to work at the Weather Institute of Hoenn and will give out weather-changing TMs for Shards.
• An old woman living at the base of Stark Mountain acts in the same way that another woman does on Route 111 in Hoenn, insisting that the player keep healing his or her Pokémon with her in a creepy manner. Strangely, they both also live just north of a sandstorm-ridden desert.
• A Swimmer north of Sunyshore City wishes to visit Hoenn's seas.
• A Socialite in the Valor Lakefront restaurant will occasionally mention the sauce of her dish was made from spicy Cheri Berries with a Hoenn-style recipe.
• Bird Keeper Audrey on Route 225 says she was born in Hoenn.

• A catalog in Rad Rickshaw's Cycle Shop in Eterna City advertises the Mach Bike and Acro Bike.
• In Stargazer Colosseum in Pokémon Battle Revolution, some of the Pokémon in the last battle depend on which game is linked to the Wii. If Diamond is linked, one of the Pokémon is Kyogre, Sapphire's version mascot, and if Pearl is linked, one of the Pokémon is Groudon, Ruby's version mascot.
• The fourteen foreign Pokédex entries in Diamond and Pearl are all from the respective translated versions of Pokémon LeafGreen.

• Mr. Pokémon is said to have gotten the Red Orb or Blue Orb from a friend in Hoenn.
• Steven Stone, Hoenn's former champion, is present in Vermilion City, and will speak of a strange Hoenn-native Pokémon that has been reported roaming Kanto.
