???

The ??? type (Japanese: ???タイプ ??? type), unlike the Bird-type, is a non-glitch elemental type in existence from Generation I onward. However, no Pokémon bears this type. Pokémon eggs are typed solely with this before they hatch, and by extension, bad eggs are also of the ??? type.

Weaknesses and resistances

The ??? type has neither any weaknesses nor resistances.

???-type Pokémon

There are no Pokémon of the ???-type except for the Egg.

???-type moves

Curse

Introduced in Pokémon Gold and Silver, Curse is a move with the ??? type.

Curse behaves differently depending on the type of the Pokémon using it; more specifically, if the Pokémon is of the Ghost-type, it will cut their HP in half and place a curse on the target Pokémon, while for any other type it will merely lower the Pokémon's Speed to raise Attack and Defense.

There is no actual purpose in Curse being a ???-type move besides its mysterious nature. If hacked to be of any other type, the move will still work as normal.

Shadow moves

Shadow moves are another kind of Pokémon attacks with the type ???.

In Pokémon Colosseum, Shadow Pokémon have the move Shadow Rush until they are purified. In Pokémon XD: Gale of Darkness, more Shadow moves are introduced. Starting in Pokémon XD: Gale of Darkness, these moves are super-effective against regular Pokémon and not very effective against other Shadow Pokémon.

???-type moves do not run exclusively off of the user's Attack or Special Attack stat, instead depending on the move. This would later be extended to moves of the rest of the types in Generation IV.

Non-Shadow moves

In every other game, ???-type offensive moves, although none exist, can be hacked in. Even with a base power of 255 (the highest that the game allows) the move will do almost no damage.

Arceus

Arceus's Multi-Type ability allows it to change types based on which plate it holds. Although there is no known plate that will make it a ???-type, the code for Diamond and Pearl has a sprite for ???-type Arceus. This may mean that there may be a way to get a plate that will change Arceus to this type via a future Nintendo event.
