Sableye is a bipedal Pokémon with a dark purple body, armed with sharp teeth and claws. It has pale blue, gemstone-like eyes, which allow it to see in low light and sparkle in the dark. It also has a red gemstone on its chest, and its back has a blue and green gemstone as well as another red one. These gem-like eyes and adornments on its body are caused by its diet, which consists of rocks and raw gemstones. It also targets Carbink as prey, though they are usually taken by Gabite before Sableye can reach them. It is feared by people, since it is said to steal a person's soul if they look into its eyes. It is nocturnal and is rarely seen. It lives in caves.
As Mega Sableye, all the energy from its Mega Evolution is concentrated into the red jewel on its chest, causing it to detach from Sableye's body and significantly increase in size; the detached jewel leaves a small hole in Mega Sableye's chest. Its ears elongate, and it gains a spike on the top of its head. Its teeth turn from white to yellow, and its eyes also change from pale blue to a crimson red, with diagonal slits at their inner edges. Its back gains more gems: a second green one, a second red one and two small yellow gems. The enlarged jewel is said to boast such incredible hardness that no attack can even leave a scratch on it. During battle, Mega Sableye shelters itself behind the jewel, from where it can take advantage of any openings its target leaves exposed. However, being forced to support its massive jewel leaves Sableye unable to turn quickly, making it vulnerable from behind.
Pokémon Mystery Dungeon: Explorers of Sky: Six Sableye perform the same role as above, and in addition appear in Special Episode 5, which contains the events happening after Grovyle returns to the future with Dusknoir, and play a role in the episode's plot.
This Pokémon was unavailable prior to Generation III.
Sableye shares its category with Murkrow. They are both known as the Darkness Pokémon.
Sableye has the lowest base stat total of all fully evolved Dark-type Pokémon.
Mega Sableye is tied with Mega Mawile for having the lowest base stat total of all Mega Evolved Pokémon, at 480, and is tied with Mega Camerupt for having the lowest Speed stat of all Mega Evolved Pokémon, at 20.
Prior to the introduction of the Fairy type in Generation VI, Sableye (along with Spiritomb) had no elemental weaknesses under normal battle conditions (using Foresight can expose its Dark-type vulnerability to Fighting). As this occurred without the aid of an Ability, it was commonly hacked to have the ability Wonder Guard, making it immune to all direct damage. This hack is commonly referred to as Wondereye.
Mega Sableye is the shortest Mega-Evolved Pokémon, standing at 1'08" (0.5 m).
Sableye is a stylization of the Hopkinsville Goblin, a creature from an alleged Kentucky "alien encounter" described as having shining eyes, small legs, clawed arms and swaying hips (a movement that Sableye imitates in the 3D Pokémon games). The Hopkinsville aliens are most famous in Japan, where they have appeared in other anime and video games.
