'''Devolution''' (Japanese: '''{{ruby|退|たい}}{{ruby|化|か}}''' ''degeneration'') is the process by which an [[Evolution|evolved]] {{OBP|Pokémon|species}} reverts to its previous form. This process is much less common than Evolution due to being impossible within the [[core series]] {{pkmn|games}}. In most media in which it exists, devolution is often instigated through artificial means, such as sprays or genetic engineering.

==In the core series games==
[[File:Slowking losing Shellder.png|left|thumb|200px|{{p|Slowking}} losing {{p|Shellder}}]]
While devolution is not possible within the [[core series]] games as a mechanic, the notion is referred to by {{p|Slowbro}}'s numerous [[Pokédex entry|Pokédex entries]]. Said entries claim that if the {{p|Shellder}} falls off, the Slowbro turns back into a Slowpoke. It is said that if {{p|Slowking}} loses its Shellder, it forgets everything it has learned.<ref>[http://www.pokemon.jp/special/yadon_paradise/illustrated/ 絵で見るヤドンずかん｜  ヤドンパラダイス｜ポケモンだいすきクラブ]</ref>

A similar situation applies to {{p|Exeggutor}}, as it is stated in its Pokédex entries that if one of its heads were to fall off, that head would become an {{p|Exeggcute}}.

The {{g|Moon}} Pokédex entry for {{p|Vanilluxe}} mentions that it can lose one of its heads and continue living without much trouble. That would essentially make it resemble {{p|Vanillish}}, its pre-evolved form.

{{p|Silvally}}, a Pokémon who had previously gone by the name ''[[Beast killer project|Type: Full]]'' were given control helmets to prevent its {{a|RKS System}} from functioning. This had caused the Pokémon to be renamed to {{p|Type: Null}}. In gameplay, Type: Null can only evolve into Silvally, breaking the helmet that once constrained it.

In {{p|Melmetal}}'s Pokédex entry for [[Pokémon Sword and Shield|Pokémon Sword]], it is stated that, at the end of a Melmetal's lifespan, its leftover shards will return to being {{p|Meltan}}.

==In the spin-off games==
===Pokémon Mystery Dungeon===
The only Pokémon games in which devolution is possible are games from the [[Pokémon Mystery Dungeon series]] games of the [[Nintendo 3DS]].

In [[Pokémon Mystery Dungeon: Gates to Infinity]], the Devolve Orb is a [[Wonder Orb]] that devolves all enemies in the room.
{{spoilers}}
In [[Pokémon Super Mystery Dungeon]], the player and their partner evolve and later devolve three times during the game's main story, thanks to the [[Harmony Scarf|Harmony Scarves]] they wear.

===Pokémon Trading Card Game===
Pokémon cards can devolve in {{cat|Pokémon Trading Card Game video games}}, which contain cards that can cause devolution.

===Pokémon UNITE===
Before a [[Unite Battle]], all participating Pokémon are reduced to [[level]] 1 through the power of [[Aeos energy]].<ref name="UNITEPress">[https://press.pokemon.com/en/releases/NEW-INFORMATION-REVEALED-FOR-Pokemon-UNITE NEW INFORMATION REVEALED FOR Pokémon UNITE], Press release</ref> This seemingly also induces devolution in the affected species; however, the process is not seen within the bounds of the video game. Pokémon with {{pkmn2|baby}} forms, such as {{p|Pikachu}} and {{p|Mr. Mime}}, are never seen in such stages and presumably do not devolve that far, while {{p|Azumarill}} only devolves to {{p|Marill}}.

The [[Pokémon UNITE Opening Cinematic|opening cinematic]] for [[Pokémon UNITE]] shows {{UNITE|Talonflame}}, {{UNITE|Slowbro}}, {{UNITE|Greninja}}, {{UNITE|Cinderace}}, and {{UNITE|Garchomp}} enveloped by a blue aura and devolving into their base forms of {{p|Fletchling}}, {{p|Slowpoke}}, {{p|Froakie}}, {{p|Scorbunny}}, and {{p|Gible}}, respectively. Notably, {{UNITE|Pikachu}}, {{UNITE|Mr. Mime}}, {{UNITE|Absol}}, {{UNITE|Lucario}}, and {{UNITE|Snorlax}} are seen enveloped in the same blue aura but are unaffected.

In the Practice Area mode, if the player uses the Reset Level function in the Practice Options menu to return a Pokémon to Level 1, that Pokémon will devolve back into their base form. Just like [[Evolution]], Pokémon are {{UNITE|status condition|invincible}} while devolving. The same visual effects from Evolution indicate devolution.

==In animation==
[[File:Devolution anime.png|thumb|250px|{{TP|Jessie|Wobbuffet}} devolving in {{aniseries|JN}}]]
===''Pokémon the Series''===
In {{aniseries|PTS}}, the subject of devolution has rarely been brought up. {{an|Brock}} explicitly states in ''[[EP014|Electric Shock Showdown]]'' that Evolution cannot be reversed, effectively confirming the nonexistence of devolution within the series. This was reconfirmed in ''[[XY052|A Stealthy Challenge!]]'', where {{an|Bonnie}} asked {{AP|Frogadier}} to devolve into {{p|Froakie}} so she could see it evolve again, but {{an|Clemont}} explained that it doesn't work that way. However, special circumstances have caused some Pokémon to devolve in the series.

===={{aniseries|XY}}====
In ''[[XY098|Dream a Little Dream from Me!]]'', [[Ash's Pikachu]] had a nightmare featuring Frogadier having devolved into Froakie. [[Clemont's Bunnelby]], which appeared as a {{p|Diggersby}} in the same nightmare, also devolved back into its first stage later in the dream.

===={{aniseries|SM}}====
The first known instance of a real devolution in the series occurred when {{an|Faba}} fitted {{TP|Gladion|Silvally}} with a restraining mask, thereby turning it into a {{p|Type: Null}}.

===={{aniseries|JN}}====
In ''[[JN089|The Gates of Warp!]]'', Pokémon in an {{pkmn|multiverse|alternate world}} version of [[Sinnoh]] devolved due to {{OBP|Dialga|recurring}} and {{OBP|Palkia|recurring}}'s battle, with most of them eventually reverting all the way into {{pkmn|Egg}}s. In ''[[JN090|Showdown at the Gates of Warp!]]'', this battle was revealed to have been orchestrated by [[Alternate World Team Rocket]] to make Pokémon easier to steal and train to serve them. Once they had been defeated, {{Ash}}, {{an|Dawn}}, [[Goh]], [[Chloe]], and their alternate world counterparts prayed for {{p|Arceus}} to stop the fight, which it did. Afterwards, Dialga and Palkia restored the reverted Pokémon to normal, fulfilling everyone's wish.

==In the manga==
[[File:Devolution Adventures.png|thumb|220px|Eevee devolving from {{p|Jolteon}} in [[Pokémon Adventures]]]]
===Pokémon Adventures===
===={{MangaArc|Red, Green & Blue}}====
Prior to his debut in ''[[PS020|Blame It on Eevee]]'', {{adv|Red}}'s {{p|Eevee}}, [[Vee]], had been the subject of an experiment by [[Team Rocket]], which allowed him to evolve into any of his three [[Eeveelution|Evolutions]] that were known [[Generation I|at the time]]. He was also able to devolve back into an Eevee and evolve into a different Eeveelution. This ability was lost once Vee {{MangaArc|Gold, Silver & Crystal|later}} permanently evolved into {{p|Espeon}}. Although this does mean that devolution is possible in [[Pokémon Adventures]], the artificial means through which this was achieved and the lack of any other instances of devolution suggest that it may not be possible through natural means.

===Pokémon Pocket Monsters===
Unlike any other media, Pokémon are capable of devolving just as easily as they evolve in [[Pokémon Pocket Monsters]]. This became especially evident when [[Red's Clefairy]] and {{PPM|Red's Pikachu|Pikachu}} evolve into {{p|Clefable}} and {{p|Raichu}} respectively, then revert to their original forms, as well as when {{PPM|Green}}'s {{p|Charmander}} evolved into {{TP|Green|Charizard}} and then turned back into Charmander.

===Pokémon Horizon===
{{OBP|Akira|Horizon}}'s {{p|Rockruff}} has the unique ability to evolve into {{p|Lycanroc}} and then devolve into Rockruff again, thanks to the strange red stone on its neck. It also has the ability to change in between its {{form|Lycanroc|Midday and Midnight Forms}} while being evolved.

==In the TCG==
[[File:DevolutionSprayDragonsExalted113.jpg|thumb|200px|{{TCG ID|Base Set|Devolution Spray|72}}, an example of a card that can induce devolution in the TCG]]
In the [[Pokémon Trading Card Game]], devolution is possible through effects rather than as a natural mechanic.

Devolution is performed by removing one or more of the {{TCG|Evolution card}}s on top of the {{TCG|Pokémon}} and moving them to another {{TCG|zone}}. Typically, the cards return to their owner's [[hand]]. This leaves one of the lower stages of that Pokémon visible, and that prior card is now in play. A Pokémon cannot be devolved past whichever card was put into play without Evolution, remaining in play no matter what effect is trying to devolve the Pokémon, even if that card happens to be an Evolution card.<ref>[https://compendium.pokegym.net/ruling/1945/ Compendium ruling]</ref> For example, if a {{TCG ID|BREAKpoint|Frogadier|39}} is directly put onto the [[Bench]] rather than via evolution, it cannot be devolved because it is an unevolved Pokémon and therefore does not have previous Evolutions. If this Frogadier evolves into {{TCG|Greninja}}, effects that attempts to remove multiple Evolution cards like {{TCG ID|Shining Legends|Shining Jirachi|42}}'s ''Stellar Reign'' {{TCG|Attack}} would only remove the Greninja; Frogadier would stay in play.

Damage counters and other effects are kept onto the devolved Pokémon. A Pokémon that devolved cannot evolve on the same turn, unless some other effect bypasses this limitation.

As a {{TCG|Pokémon LV.X}} is not an Evolution card, only evolved LV.X can be devolved. When doing so, both the earlier evolution that the Pokémon LV. X is on top of and the Pokémon LV. X are removed.<ref>[https://www.judgeball.com/files/archives/tcg-rulebooks/en/PL2.pdf Platinum: Rising RIvals Rulebook], via Judge Ball</ref>

One of the primary purposes of devolution is reducing the {{TCG|HP}} of a Pokémon, as HP usually increases as a Pokémon evolves and damage counters are kept, which may result in the Pokémon being Knocked Out. Another use case is reusing effects, such as {{TCG|Ability|Abilities}}, although reusing effects in this manner is usually restricted for the next turn due to the Evolution limitations, unless an effect allows for that Pokémon to immediately evolve or another Pokémon in play can already evolve into the returned card.

The following is a list of cards that can induce devolution.
