Its special abilities are either Keen Eye or Stall. It hides in the darkness of caves. Its diet of gems has transformed its eyes into gemstones. As a Dark/Ghost-type, it has no weaknesses.
Sableye has deep, purple colored fur with little claws, pointed ears, and sharp teeth. It also had two big gemstones over its eyes, with a gem on its tummy and three gems on its back. It resembles a Hopkinsville goblin.
Pokémon Mystery Dungeon: Explorers of Time & Explorers of Darkness
In this game the Sableye are the servants of Dusknoir, and are constantly spying on and trying to capture the player Pokémon in the world of the future. However, when Dusknoir reforms in the special episode, they do so as well. They demonstrate this by first attacking Primal Dialga to protect Dusknoir (though they are easily blasted away by his Roar of Time) and later by locating Primal Dialga when he is searching for a Passage of Time.
Sableye is the first of the two Pokémon that cannot be hit with a super effective attack under normal conditions, Spiritomb being the other.
Because of this, if a cheat device is used to give Sableye the Wonder Guard ability, it will become invincible.
They can be beaten when a Pokémon uses Foresight and then another Fighting-type move.
The word Sable is an adjective commonly used to describe the black fur of some animals.
Sableye was a Pokémon exclusive to Sapphire version. Similarly, it is considered a HeartGold exclusive though it can be caught on the Pokéwalker route Rally, which is only available through means of an event.
