Protean (Ability)

Protean (Japanese: へんげんじざい Protean) is an Ability introduced in Generation VI. This Ability is exclusively obtained as a.

In battle
Immediately before using any move (except ), a Pokémon with Protean as its Ability will change its type to be the same type as the move it is using. Protean always causes the user to become a single-type Pokémon.

Because Protean activates prior to executing a move, the user will receive same-type attack bonus on every move it uses (except Struggle) regardless of the move's type, and will always hit with the move.

When using a (such as ), the type of the called move will be considered. When using a or if the move has been affected by  or, the type it changes to will be considered. When using a move that changes the user's type, such as, first Protean changes the user's type to the type of the move, then the move will either fail or change the user's type again. When using (unless its type is changed by ), if the user is not already  prior to the activation of Protean, Protean will change the user to Ghost-type, then the user will use the Ghost-type effect of Curse on itself (regardless of  and  or ).

Protean will not activate if the move fails (unless it fails due to the activation of Protean), if the execution is interrupted entirely (such as by the effect of infatuation or confusion), if the move is prevented by heavy rain or extremely harsh sunlight, or if the move is prevented by. Protean will activate even if the move misses, is blocked by a, or fails to affect the opponent. Protean will still change the user's type when using and, regardless of whether the move successfully executes or not.

The user's new type remains in effect until changed again or until the user is switched out; negating or replacing the Ability does not change the user back to their original type.

Outside of battle
Protean has no effect outside of battle.

Trivia

 * Since cannot be a  move and neither Kecleon nor Greninja's evolution line can know a Fairy-type move, no Pokémon that normally has Protean can use it to become Fairy-type.
