Type change

Type change is a mechanic available in Pokémon battles.

Effect

Some moves and Abilities cause a Pokémon's types 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 switched out, 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 Grass via Forest's Curse or Ghost via 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 Burn Up or 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 conditions, such that a Pokémon cannot be poisoned after gaining the Poison-type or Steel-type; or conversely, an originally Poison-type or Steel-type 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 Conversion in Generation I only, Reflect Type, Transform, or via Imposter), the target's type changes are copied as well. If the target is currently typeless, the user will become a pure Normal type. However, if the target was typeless and then gained a type via Forest's Curse or Trick-or-Treat, the user will have two types: Normal and the added one.

The type changes are not transferred via Baton Pass.

Terastallizing

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 Adaptability).

In spin-off games

Pokémon Mystery Dungeon series

Reason: 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 dungeon.

Prior to Gates to Infinity, the move Conversion 2 caused the 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 the anime

 
Arceus changing into a Ghost type with Multitype
 
Gladion's Silvally changing into a Dark type with RKS System
 
Leon's Cinderace with its type changed into Ground via Libero

In the anime, the possibility of changing types was rarely mentioned onscreen prior to Pokémon Journeys: The Series, with the notable exceptions of Arceus and Silvally, whose Abilities—Multitype and RKS System, respectively—are integral to the Pokémon's biology and, as such, were heavily featured when the Pokémon was battling.

Several moves and Abilities that change Pokémon's types in the games have appeared, but are not known to do the same, in the anime:

  • 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.
  • Transform has been used on multiple occasions by Ditto and Mew, turning them into a copy of the target and allowing them to use moves from the Pokémon they copied.
  • Camouflage and Color Change work similarly, turning the user invisible.
  • Zen Mode changes Darmanitan's form, but the type change included in this process has yet to be explicitly mentioned.
  • Relic Song does not appear to deal damage, but still changes Meloetta's forms, affecting its battle style and available moves, and it makes plants grow as well.
  • Forest's Curse binds the targets with vines from below.

The type-changing Abilities Imposter, Protean, and Mimicry, as well as the moves Conversion 2, Roost, Reflect Type, Soak, Magic Powder, and Double Shock, were never shown to be used in the anime.

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