Flavor (Optional): Sableye get by with their favourite diet of stones and crystals, and as a result, many of the stones undigested by this Pokemon become part of its body, surfacing and staying on its skin. Through the power given off by the mega stone, the minerals inside its body and hardens around its skin, especially around its hands, causing them to become extremely sharp around its claws. It last gets a massive boost in its body strength and sight, allowing it to hunt for days without rest and even see in the dark, making for great thieves if they end up inside a city, though there they fight against any Weavile they encounter, typically slaying and eating their corpses without a worry thanks to its power. In the wild, they attack freely and without mercy, hunting down and killing Carbink without mercy. (Sun Pokedex entry)
Competitive Description: Bisharp with a better speed, no Swords Dance and Defiant in exchange for Elemental Punches and Tough Claws. Its status movepool is still the annoyance it will always be, with Hone Claws, Will-o-Wisp, Taunt, and so on. That, and U-turn, also allow it to be unique from other Tough Claw Megas, with it able to pull of a support role with pivoting abilities.
