Various {{pkmn|battle}} mechanics, such as certain [[move]]s and {{Abilities}}, may cause a {{OBP|Pokémon|species}}'s [[type]] or the type of its moves to change or even be removed.

==In the core series games==
===Changing the type of a Pokémon===
Some moves and Abilities cause a Pokémon's [[type]]s to be temporarily changed, added, or removed in battle. The original types are still displayed in the Pokémon's [[summary]]. All type changes are undone when the Pokémon is [[Recall|switched out]], [[Fainting|faints]], or the battle ends.

Through type change, a Pokémon can have up to three types at once or no type at all:
* If a new type is added (such as {{t|Grass}} via {{m|Forest's Curse}} or {{t|Ghost}} via {{m|Trick-or-Treat}}) to a dual-type Pokémon, it will have three types at once. However, if Forest's Curse is used on a Pokémon affected by Trick-or-Treat or vice-versa, the new type will replace the previously added one.
* If one or more types are removed through {{m|Burn Up}} or {{m|Double Shock}}, and the Pokémon has no more types left, it will become [[typeless]] until it is switched out, faints, or the battle ends.

The type change can add or remove type-related immunities to [[status condition]]s, such that a Pokémon cannot be {{status|poison}}ed after gaining the {{type|Poison}} or {{type|Steel}}; or conversely, an originally {{type|Poison}} or {{type|Steel}} Pokémon can become poisoned after its type has changed (and will remain poisoned even after the battle ends). However, any status conditions the Pokémon already has are not influenced by the type change; for example, a poisoned Pokémon will retain this status condition even after becoming a Poison or Steel type.

If a Pokémon copies the types of another (by using {{m|Conversion}} in [[Generation I]] only, {{m|Reflect Type}}, {{m|Transform}}, or via {{a|Imposter}}), the target's type changes are copied as well. If the target is currently typeless, the user will become a pure {{t|Normal}} type. However, if the target was typeless and then gained a type via {{m|Forest's Curse}} or {{m|Trick-or-Treat}}, the user will have two types: Normal and the added one.

The type changes are not transferred via {{m|Baton Pass}}.

|}
|}

=====Terastallizing=====
{{main|Terastal phenomenon}}
After Terastallizing, a Pokémon will change from its original typing to its Tera Type. It will keep the {{STAB}} of its old type(s), but will also gain STAB for moves of its Tera Type. If a Pokémon's Tera Type matches one of its original types, STAB for moves of that type will be raised to a modifier of 2× (2.25× for a Pokémon with {{a|Adaptability}}). It is also the only way that a Pokémon can gain the [[Stellar (type)|Stellar]] type.

===Changing the type of a move===
There are a few moves that can change their type depending on various conditions.

==In the spin-off games==
===Pokémon Mystery Dungeon series===
{{incomplete|section|Confirm if a Pokémon that has changed type (such as from Conversion or Color Change) gains the terrain abilities, such as a Water-type Pokémon able to walk on water, or a Ghost-type Pokémon able to go through walls}}

In the [[Pokémon Mystery Dungeon series]], most of the available moves and Abilities that change a Pokémon's type simply work as in the [[core series]]. The temporary type changes last only in the current floor of the [[mystery dungeon|dungeon]].

Prior to [[Pokémon Mystery Dungeon: Gates to Infinity|Gates to Infinity]], the move {{m|Conversion 2}} caused the [[Status condition (Mystery Dungeon)#Conversion 2|status condition of the same name]] for 11 turns. If the Pokémon with this status condition is hit by a move, it will turn into a type that has the best matchup against it (even if it's a non-damaging move).

==In animation==
[[File:Arceus M12 Multitype.png|thumb|230px|{{OBP|Arceus|M12}} changing into a {{t|Ghost}} type with {{a|Multitype}}]]
[[File:Gladion Silvally RKS System Dark.png|thumb|230px|[[Gladion's Silvally]] changing into a {{t|Dark}} type with {{a|RKS System}}]]
===''Pokémon the Series''===
The possibility of changing types was rarely mentioned on-screen prior to {{aniseries|JN}}, with the notable exceptions of {{p|Arceus}} and {{p|Silvally}}, whose {{Abilities}}—{{a|Multitype}} and {{a|RKS System}}, respectively—are integral to the Pokémon's biology and, as such, were heavily featured in battle.

Several [[move]]s and Abilities that change Pokémon's types in the games have appeared, but are not known to do the same in {{aniseries|PTS}} include:
* {{m|Conversion}} (Japanese: テクスチャー ''Texture'') has the user copy the target's color and texture. While unconfirmed, Conversion appears to alter the way the user is affected by opposing attacks, as if its type also had changed.
* {{m|Transform}} has been used on multiple occasions by {{p|Ditto}} and {{p|Mew}}, turning them into a copy of the target, and allowing them to use [[move]]s from the Pokémon they copied.
* {{m|Camouflage}} and {{a|Color Change}} work similarly, turning the user invisible.
* {{a|Zen Mode}} changes {{p|Darmanitan}}'s form, but the type change included in this process has yet to be explicitly mentioned.
* {{m|Relic Song}} does not appear to deal damage, but still changes {{p|Meloetta}}'s forms, affecting its battle style and available moves, and it makes plants grow as well.
* {{m|Forest's Curse}} binds the targets with vines from below.

The type-changing Abilities {{a|Imposter}}, {{a|Protean}}, and {{a|Mimicry}}, as well as the moves {{m|Conversion 2}}, {{m|Roost}}, {{m|Reflect Type}}, {{m|Soak}}, and {{m|Magic Powder}}, have never been shown to be used in the series.

Despite Soak having not appeared in the series, its effect of turning the target into a pure {{type|Water}} to allow {{type|Electric}} attacks to hit Pokémon normally resistant or outright immune to them, like {{t|Ground}} types, have been directly referenced in ''[[SM109|A Grand Debut!]]'', after [[Ash's Pikachu]] drenched [[Hapu's Mudsdale]] in seawater, allowing him to finish the battle off with a {{m|Gigavolt Havoc}}. This effect can be traced even further back to ''[[EP005|Showdown in Pewter City]]'', prior to the move even debuting in the games, when Ash's Pikachu defeated [[Brock's Onix]] with an Electric attack after it had been doused by the sprinklers.

====''[[M12|Arceus and the Jewel of Life]]''====
In ''[[M12|Arceus and the Jewel of Life]]'', {{OBP|Arceus|M12}} changed between types with {{a|Multitype}}. This marks the first time a type change is confirmed to have happened in animated series-related media, as Arceus changed into a {{t|Ghost}} type to turn itself immune to {{OBP|Palkia|movie}}'s {{m|Aura Sphere}}.

===={{aniseries|SM}}====
In ''[[SM049|Mission: Total Recall!]]'', [[Gladion's Silvally]] changed type for the first time using the {{a|RKS System}}, turning into a {{t|Dark}} type with the [[Dark Memory]]. It did the same with other [[Memory|Memories]] throughout the rest of the series.

===={{aniseries|JN}}====
In ''[[JN068|Advice to Goh!]]'', a {{pkmn2|wild}} {{p|Moltres}} lost its {{t|Fire}} type after using {{m|Burn Up}}.

In ''[[JNS04|The Arceus Chronicles (Part 4)]]'', a wild {{p|Arceus}} changed into a {{t|Water}} type with {{a|Multitype}}.

In ''[[JN116|Pride of a Champion!]]'', [[Diantha]]'s {{p|Gourgeist}} used {{m|Trick-or-Treat}} and added the {{t|Ghost}} type to [[Lance's Gyarados]], allowing Gourgeist to deal more damage with its Ghost-type attacks. It also did the same with Lance's {{p|Hydreigon}}, though this didn't come into play at any point.

In ''[[JN129|A Flood of Torrential Gains!]]'', {{an|Leon}}'s {{p|Cinderace}} had its type changed by {{a|Libero}} for the first time: after using {{m|Scorching Sands}}, it became a pure {{t|Ground}} type, making it immune to Ash's Pikachu's {{m|Thunderbolt}}.

===''Pokémon Horizons: The Series''===
Similar to the games, {{Tera}}stallization has been used to change a Pokémon's type on multiple occasions, first being shown in ''[[HZ010|Nemona and Brassius and...]]'' when [[Brassius]] Terastallized his {{p|Sudowoodo}} into a {{t|Grass}} type.

==In the manga==
[[File:Gladion Silvally RKS System Adventures.png|thumb|230px|Silvally changing into a Rock type via the RKS System in [[Pokémon Adventures]]]]
===Pokémon Adventures===
===={{MangaArc|Yellow}}====
In ''[[PS077|Striking Golduck]]'', {{adv|Blue}}'s {{p|Porygon}} used {{m|Conversion}} to become a {{t|Ghost}} type and make [[Agatha's Gengar]]'s physical attacks ineffective against it.

===={{MangaArc|Gold, Silver & Crystal}}====
In ''[[PS160|Playful Porygon2]]'', [[Blue's Porygon2]] used {{m|Conversion 2}} to become a {{t|Dark}} type in order to resist the attacks from [[Silver's Sneasel]].

===={{MangaArc|HeartGold & SoulSilver}}====
In ''[[PS455|All About Arceus IV]]'', [[Archer]] used the [[Plate]]s gathered by {{adv|Silver}} to activate {{adv|Arceus}}'s {{a|Multitype}} and change its type several times as a demonstration of Arceus's powers.

===={{MangaArc|X & Y}}====
In ''[[PS591|Mewtwo Angered]]'', [[Emma|Essentia]]'s {{adv|Zygarde}} used {{m|Camouflage}} to change its type and blend into its surroundings while battling [[Blaine]]'s {{adv|Mewtwo}}.

In ''[[PS595|Magearna Moves]]'', [[Cassius]]'s {{p|Gourgeist}} used {{m|Trick-or-Treat}} to turn {{p|Magearna}} into a Ghost type and give it the type's weaknesses.

===={{MangaArc|Sun, Moon, Ultra Sun & Ultra Moon}}====
In ''[[PASM34|Destroy!! Results of the Training!]]'', [[Gladion's Silvally]] was revealed to have changed into a {{t|Fire}} type using its {{a|RKS System}} to free {{adv|Moon}} from the cell she was held in. Later, Moon used a [[Rock Memory]] to change Silvally into a {{t|Rock}} type to fight [[Ryuki]]'s {{p|Turtonator}} more effectively.

===={{MangaArc|Scarlet & Violet}}====
{{Tera}}stallization has been used to change a Pokémon's type in multiple instances, the first time occurring in [[PASV01]], where {{adv|Scarlet}} Terastallized her {{p|Pikachu}} into a {{t|Flying}} type while battling [[Nemona]]'s {{p|Pawmi}}. 

===Phantom Thief Pokémon 7===
In ''[[P7-11|Into The Hands Of Evil?!]]'', [[Io]]'s {{p|Porygon-Z}} used Conversion 2 to change its type.
