The ???-type is a type that exists only in Generations II, III, and IV. It was removed in the Generation V games and has not returned.


The ???-type does not exist in Generation I. It exists in Generations II, III, and IV solely to be the type of the status move Curse; in Generation III, Eggs are also marked as ???-type. Unlike other types, the ???-type does not have any weaknesses or resistances.

If damaging moves are hacked to be of this type in the Generation II or III games, since it is considered neither a physical nor a special move, the damage dealt by a ???-type move is minimal, even if the move had the highest possible base power.


The move Curse was given the ???-type when introduced in Generation II, likely because of its mysterious nature: it is so far the only move which completely differs in its use between Pokémon of different types. It was retyped as a Ghost-type move in Generation V.


Pokémon Eggs are displayed as being ???-type in Generation III on their status screen, to maintain the fact that the identity of the Pokémon inside is supposed to be unknown. This does not appear in Generation II, which uses a special status screen for Pokémon Eggs different from that of normal Pokémon, and was removed in Generation IV, when the section of a Pokémon's status screen that displays type was separated from where it was met. From Generation IV on, Eggs are considered as Normal-type Pokémon by the game.

Weather Ball

Weather Ball XD Unknown

Castform using ???-type Weather Ball in Pokémon XD.

Weather Ball's type changes depending on the weather. If Weather Ball is used when the field is under the effect of Shadow Sky, Weather Ball changes to a ???-type move and will not have any weaknesses or resistances. Despite this, if a Pokémon with Color Change is hit with this move under these conditions, it will be changed to a Normal-type Pokémon.

This situation is the only way to legitimately encounter the type effectiveness of a ???-type move.
