In the core series games
Pokémon Black and White
In Pokémon Black and White, it is said that Opelucid City is different in another world, with there being an alternate version of the city that is traditionalB/modernW, referencing the fact that the city differs between the two versions of the game. The character ThymeB/BachW (on the second floor in the building east of Drayden's house) requests to be shown a Pokémon that knows Charge from the alternate world and rewards the player with a Cell Battery once they show him such a Pokémon originating from the opposite version of the game.
Pokémon Omega Ruby and Alpha Sapphire
In Pokémon Omega Ruby and Alpha Sapphire, Zinnia mentions that there is another similar yet different world where the war in Kalos 3000 years ago never occurred, so the ultimate weapon was never built and Mega Evolution consequently does not exist. This world contains an alternate version of the Hoenn region. This is a reference to Pokémon Ruby, Sapphire, and Emerald, which are earlier games set in Hoenn that lack Mega Evolution.
In Pokémon Omega Ruby and Alpha Sapphire, ArchieOR/MaxieAS mentions another world in which the player would battle Team AquaOR/Team MagmaAS. This is a reference to the opposite version of the game, implying that Pokémon Omega Ruby and Alpha Sapphire take place in alternate universes to each other.
Pokémon Sun, Moon, Ultra Sun, and Ultra Moon
The individual titles take place in different universes from one another.
In Pokémon Sun and Moon's climax, Lusamine uses Nebby's power to create an Ultra Wormhole so that she and Guzma could travel through Ultra Space. Multiple Ultra Wormholes are created by this event, having Ultra Beasts travel from other worlds into Alola. Lillie and the player travel through Ultra Space, finding Lusamine and Guzma in an unnamed location simply titled "Ultra Space." This location is renamed to the Ultra Deep Sea in Ultra Sun and Ultra Moon.
In Pokémon Ultra Sun and Ultra Moon's climax, Lusamine and Guzma simply open a single wormhole to prevent Necrozma from coming to Alola instead. At Poni Island's altar, the two seemed to have failed and multiple wormholes are instead unleashed by Necrozma, allowing for an Ultra Beast invasion. Necrozma heads to Ultra Megalopolis, with the player following.
After Sun and Moon's main plot, Anabel is mentioned to have fallen onto Poni Island from another universe through an Ultra Wormhole, and was found by Looker and Nanu ten years before the events of the games. She remembers that she came from Hoenn and was a powerful Trainer who protected a tower, referencing her role in Pokémon Emerald.
In Episode RR in Ultra Sun and Ultra Moon, Giovanni comes to Alola from an alternate universe in which Team Rocket was successful in achieving its goals. He then forms Team Rainbow Rocket by summoning other villainous team leaders from alternate worlds where they each also succeeded in their goals: Maxie, Archie, Cyrus, Lysandre, and Ghetsis. All of these leaders use the Legendary Pokémon they have successfully captured from their original titles. Colress uses his technology to send them back to their original worlds after they are each defeated by the player. Episode RR ends with Giovanni wondering what other worlds he could attack next before vanishing on his own.
After the player becomes the Champion, a rift appears at the Altar of the SunneSUS/Altar of the MooneMUM, which can be opened into an Ultra Wormhole and traveled through if the player has a Solgaleo or Dusk Mane Necrozma in their party at night or a Lunala or Dawn Wings Necrozma in their party during the day. The Ultra Wormhole leads to an alternate universe, known as the reverse world. It is near-identical to the main world, but the time of day is inverted and the Altar of the SunneSUS/Altar of the MooneMUM and Lake of the MooneSUS/Lake of the SunneMUM are both replaced by their counterparts from the opposite version. An Ultra Wormhole remains at the altar, allowing the player to return to the original world at any time. By going into the reverse world and bringing a SolgaleoSUS/LunalaMUM to the lake on Ula'ula Island, the Legendary Pokémon's counterpart will briefly appear before the player's and the two of them will create a Cosmog that the player can obtain.
In Ultra Sun and Ultra Moon, through the Ultra Warp Ride, it is possible to travel to other worlds by traveling through Ultra Space, including an alternate universe's version of Alola known as the Ultra Ruin, which has been destroyed by Guzzlord.
The Ultra Recon Squad are a group of individuals who debuted in Ultra Sun and Ultra Moon. They are come from Ultra Megalopolis, a location different from the Pokémon world that the main game takes place in. They were summoned by Lusamine to help study Cosmog and Necrozma.
Pokémon Legends: Arceus
In Pokémon Legends: Arceus, the player character travels across space and time to land in Hisui, the Sinnoh region in the distant past, through the space-time rift that is looming over Mount Coronet. They struggle to remember where they come from, although they do have insight on what the world they come from is. Ingo, a Subway Boss from Unova, also appears in this game and is in a similar situation to that of the player, having lost most of his memories from traveling across space and time. Both Ingo and Cogita suggest that the space-time rift may link different worlds.
Pokémon Scarlet and Violet
In Pokémon Scarlet and Violet, if the player goes to the Crystal Pool with Briar's Book, Terapagos creates a cloud of mist from which Professor SadaS/Professor TuroV appears, time traveling from the past. The professor notes their displacement across space and time and speculates that the encounter might be occurring in a different timeline to their own (though this seems to be contradicted by the fact that the encounter is mentioned in the professor's journals in the Area Zero Underdepths). They also mention that they are working on a time machine to catch Pokémon from other timelines and transport them to the present day in their own timeline. After trading their copy of the Scarlet BookS/Violet BookV for Briar's Book, the professor vanishes in the mist, returning from whence they came.
In the spin-off games
The teaser trailer for the debut of Team GO Rocket contains the line "Earth is where I shall unleash my evil schemes next!" referencing a line stated by Giovanni before his leave in Ultra Sun and Ultra Moon. Implying the real world of Earth takes place in another dimension from that of Ultra Sun and Ultra Moon.
Ultra Wormholes are found in the game, along with comes Ultra Beasts and the GO Ultra Recon Squad, who's only known member is Rhi. Like the other Ultra Recon Squad members from the core series, Rhi's home is Ultra Megalopolis. The occurrence of Ultra Wormholes has caused Professor Willow to disappear.
A different version of Ghetsis from Pokémon Black 2 and White 2 is playable in this game. Before arriving in Pasio, Ghetsis was about to confront the player from the original game when he was also interrupted by Hoopa's ring.
During the Twin Stars Far Apart story event, Liza and Anabel wind up in an alternate world version of Pasio through an Ultra Wormhole. This world appears to house no humans, but does contain several Ultra Beasts, which appear to have wound up there by chance. The two Trainers eventually return to their own world through another wormhole.
Any character who originates from Pokémon Legends: Arceus is summoned through a space-time distortion. Rei in particular mentions that he's been sent to multiple worlds, originally coming from his own world, being sent to Hisui, and then to Pasio.
