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.
- Pokémon FireRed and LeafGreen in their entirety are a reference to Generation I's events, while the credit sequence references the version mascots of Red, Green, Blue, and Yellow.
- 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 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 possible reference to Silver. It could also be a reference to the head admin in Johto, pictured on Team Rocket's Evil Deeds.
- 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 Ragecandybar.
- 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 Johto's final five routes as well as remastered versions of Olivine City and Cianwood City.
Generation IV
To Generation I
- Professor Rowan is said to have developed the Sinnoh Dex with help from a Pokémon professor from Kanto.
- Professor Oak himself comes to Sinnoh to give the player the National Dex, 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.
- A Ninja Boy on Route 210 near Celestic Town says he wants to train with a ninja Gym Leader in a faraway land.
- 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.
- Much like the Viridian Gym, the Hearthome Gym isn't accessible when the player first arrives in its home city.
- Bebe's buddy Bill is mentioned to have developed the basic storage system.
- Veilstone City is many ways like Celadon City of Kanto, both of which are the largest city in their region. Both have a Game Corner (Rocket Game Corner in Celadon and Veilstone Game Corner in Veilstone), a prize exchange shop to accompany the Game Corner, and a Department Store (Celadon Dept. in Celadon and Veilstone Dept. in Veilstone). The villainous team of the region has two headquarters in the city: Team Rocket has Rocket Game Corner and Rocket Hideout and Team Galactic has Galactic Veilstone Building and Galactic Warehouse.
- Also, 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.
- 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 Color, the Game Boy Advance or the Game Boy Advance SP. The wallpaper showcases typical features like both types of fences, low and high grass, normal ground, a sign and a house.
- In Pokémon HeartGold and SoulSilver, the lead Pokémon in the player's party will follow the player, much like in Pokémon Yellow, where the starter Pokémon follows the player.
To Generation II
- A news report of a red Gyarados begins the game. The cameraman who filmed the documentary appears at the Survival Area.
- In Platinum, the game instead begins with a report about Professor Rowan. However, the cameraman from the red Gyarados report is seen blocking the entrance to Lake Valor, hoping to get a shot of the legendary Pokémon said to live there.
- A man, who gives the player a Happiny egg in Diamond and Pearl, says that Professor Elm recently announced that eggs kept with a Trainer will eventually hatch.
- Jasmine, one of Johto's Gym Leaders, appears to give the player HM07 (Waterfall).

- A Ninja Boy on Route 210 near Celestic Town says he wants to train with a ninja Gym Leader in a faraway land.
- Dragon Tamer Hayden on Route 224 mentions that he left 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.
- Maylene's Japanese name, スモモ (Sumomo), is coincidentally shared by Kuni, a Kimono Girl.
- In Pokémon Platinum, the legendary birds can be found roaming Sinnoh following completion of the Sinnoh Dex. This may explain their absence from Kanto in Gold, Silver, and Crystal.
- In Pokémon Platinum, one of the women in the basement floor of the Veilstone Department Store mentions that the store is sold out of Ragecandybars (written as "Rage Candy Bars"), the local specialty in Mahogany Town.
- There are various similarities between Gyms and Gym Leaders between Sinnoh and Johto, including Byron and Jasmine being Template:Type2 Gym Leaders and the sixth Gym Leader of their region, and Candice and Pryce being Template:Type2 Gym Leaders and the seventh of their region.
- Pokémon HeartGold and SoulSilver in their entirety are a reference to Generation II's events.
To Generation III

- A man in Valor Lakefront states that he would like to see a rocket launch from the Space Center in Mossdeep City sometime during his life.
- A woman in Valor Lakefront claims to have lost her Suite Key. If the player finds it near the Hotel Grand Lake using the Dowsing Machine, she will offer a reward of one Lava Cookie, a specialty of Hoenn, possibly implying that her home is in that region.
- 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 Groudon, Ruby's version mascot, and if Pearl is linked, one of the Pokémon is Kyogre, Sapphire's version mascot.
- The fourteen foreign Pokédex entries are all from the respective translated versions of Pokémon LeafGreen.
