[[File:Time travel M12.png|thumb|260px|{{Ash}}, {{an|Dawn}}, {{an|Brock}}, and [[Sheena]] traveling through time in the {{pkmn|anime}}]]
'''{{wp|Time travel}}''' is an infrequent theme in the [[Pokémon]] franchise and has been depicted in several [[canon]]s, including the {{pkmn|games}}, the {{pkmn|anime}}, and various {{pkmn|manga}}. In general, stories in which a character travels through time focus on the repercussions of traveling into the past or the future. Usually, the motivation for time traveling comes from the need or desire to change history. Characters who interfere with the timeline will generally notice an altered present upon their return.

Two notable {{OBP|Pokémon|species}} possess time travel abilities. These are the {{pkmn2|Mythical}} {{p|Celebi}}, which is known as the {{pkmn|category|Time Travel Pokémon}} and has been shown to physically travel into different time periods, and the {{pkmn2|Legendary}} {{p|Dialga}}, the {{pkmn|category|Temporal Pokémon}} that can travel at will through past and future and has the power to send [[human]]s and Pokémon to specific points in time.

==In the games==
===In the [[core series]]===
* The [[Time Capsule]] is said to send Pokémon back and forth through time to explain how [[Trade|trading]] works between [[Generation I]] and {{gen|II}} games.
* In {{game|HeartGold and SoulSilver|s}}, the {{player}} and {{ga|Ethan}}/{{ga|Lyra}} travel into the past with Celebi. During a visit to two different time periods, the player discovers a part of {{ga|Silver}}'s past, as well as {{pkmn|battle}}s [[Giovanni]] to prevent him from rejoining [[Team Rocket]], at the same time when the player's past self is stopping the organization at the [[Goldenrod Radio Tower]].
* In [[Pokémon Black and White Versions 2|Pokémon Black 2 and White 2]], one of [[Pokéstar Studios]]'s [[Timegate Traveler Series|film series]] is about time-traveling to the future with a time machine.
* In [[Pokémon Legends: Arceus]], {{ga|Arceus}} sends the player back in time to the [[Hisui]] region at the start of the game. In addition, [[Ingo]] has also wound up in Hisui some time before the player's arrival through unclear means. Pokémon from the past and future are also possible to be encountered in [[space-time distortion]]s.

* In [[Pokémon Scarlet and Violet]], it is revealed that [[Professor Sada]]{{sup/9|S}}/[[Professor Turo]]{{sup/9|V}} succeeded in creating a time machine that brings Pokémon from the distant past{{sup/9|S}}/future{{sup/9|V}} to the present-day [[Paldea]], with one of those Pokémon being {{p|Koraidon}}{{sup/9|S}}/{{p|Miraidon}}{{sup/9|V}}. During the course of the games' final story arc, The Way Home, the player and their friends shut down the time machine at the behest of {{wp|Artificial intelligence|AI}} Sada{{sup/9|S}}/Turo{{sup/9|V}} before the [[Paradox Pokémon]] it has been automatically catching and bringing to the present can break out of [[Area Zero]] and overrun Paldea. After capturing Terapagos and travelling to the Crystal Pool, the player meets the real Sada{{sup/9|S}}/Turo{{sup/9|V}} from before they finished their time machine, exchanging their copy of Briar's Book for the Scarlet{{sup/9|S}}/Violet{{sup/9|V}} book. As the Professor's notes in the Area Zero Underdepths mention that they were given a book by a child, this suggests that the meeting caused a bootstrap paradox.

===In the [[Spin-off Pokémon games|spin-off games]]===
* The plots of [[Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness]] and [[Pokémon Mystery Dungeon: Explorers of Sky|Explorers of Sky]] heavily involve around time-traveling in the {{OBP|Pokémon world|Mystery Dungeon}}.

* In [[Pokémon Masters EX]], {{mas|Adaman}}, {{mas|Irida}}, {{mas|Rei}}, and {{mas|Akari}} have been transported to modern-day [[Pasio]] through a [[space-time distortion|space-time rift]].

==In the anime==
* [[Sam]] was sent 40 years into the future after meeting {{OBP|Celebi|M04}} in ''[[M04|Celebi: The Voice of the Forest]]''. There, he encountered {{Ash}} and {{ashfr}}. It is unknown if the events in the future and Sam's eventual return to the past directly altered the original timeline, but it is hinted that it might not have and these events were already present in the original timeline.
* [[Ritchie]] and [[Sparky]] were sent into the past via {{p|Celebi}} in ''[[HS13|Celebi and Joy!]]''. Events in the past directly altered the original timeline, with Ritchie assisting in the rescue of {{OBP|Nick|HS13}} and [[Nick's father|his father]] from certain death. Nick is now the mayor of [[Marion Town]] in the present day.
* {{OBP|Calista|AG076}} traveled through time via an ancient magic circle activated by her {{p|Baltoy}} and an alternate self in ''[[AG076|Me, Myself and Time]]''. It was a case of meeting one's younger self. It is unknown if the events in the past directly alter the original timeline.
* {{an|May}}, her {{TP|May|Squirtle}}, and {{MTR}} traveled through time via [[Edna]]'s locket in ''[[AG157|Time Warp Heals All Wounds]]''. Events in the past directly altered the original timeline, including the continued service of the [[Fuchsia City]] train station and {{OBP|Jonathan|AG157}} now being alive.
* Ash, {{an|Dawn}}, {{an|Brock}}, and [[Sheena]] traveled through time via {{mov|Dialga}} in ''[[M12|Arceus and the Jewel of Life]]''. Events in the past affected the original timeline, though not immediately; the changes went into effect only when {{OBP|Arceus|M12}} remembered that Ash had rescued it in the past.
* [[Ferris]] traveled through time via a portal in ''[[BW075|A Restoration Confrontation! Part 1]]'' and ''[[BW076|Part 2]]''. It was a case of arriving in the distant past as opposed to the recent past. It is unknown if the events in the past directly altered the original timeline.
* In ''[[XY054|Facing the Grand Design!]]'', the three evil {{p|Malamar}} escaped to the future with the help of large energy crystals.
* Ash, {{an|Serena}}, {{an|Clemont}}, and {{an|Bonnie}} traveled ten years into the past via {{p|Rotom}} and an elevator in ''[[XY081|Rotom's Wish!]]''. Events in the past directly altered the original timeline. [[Weston]] had originally lost his battle and the ownership of the [[Lost Hotel]] to [[Mantle]], but the group revised this and Weston was now in charge of the hotel, which no longer looked abandoned.
* In ''[[SM125|A Timeless Encounter!]]'', Ash and his {{AP|Torracat}} were accidentally sent back in time by a {{OBP|Celebi|recurring}} to when {{an|Professor Kukui}} was five years old. Ash's talks about [[Pokémon League]]s and [[Gym]]s inspired Kukui and led to him creating the [[Alola League]] in the present day.
