Type change

Various mechanics, such as certain moves and , may cause a '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 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 via or via ) 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 or , 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 ed after gaining the or ; or conversely, an originally or 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 in Generation I only, , , or via ), the target's type changes are copied as well. If the target is currently typeless, the user will become a pure type. However, if the target was typeless and then gained a type via or , the user will have two types: Normal and the added one.
The type changes are not transferred via .

==In the spin-off games==
===Pokémon Mystery Dungeon series===
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 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 animation==
