Mascaïman

Black +2: They live buried in the sands of the desert. The sun-warmed sands prevent their body temperature from dropping.

White +2: It moves along below the sand’s surface, except for its nose and eyes. A dark membrane shields its eyes from the sun.

Black 2 / White 2: They live hidden under hot desert sands in order to keep their body temperature from dropping.

Sun: It submerges itself in sand and moves as if swimming. This wise behavior keeps its enemies from finding it and maintains its temperature.

Moon: It conceals itself in the sand and chomps down on the legs of any prey that unwarily walk over it. Its favorite food is Trapinch.

Ultra Sun: Alola, where it’s warm all year round, is a comfortable environment for this Pokémon. Sometimes you’ll even see it outside of deserts.

Ultra Moon: Sandile’s still not good at hunting, so it mostly eats things that have collapsed in the desert. It’s called “the cleaner of the desert.”

Sword: The desert gets cold at night, so when the sun sets, this Pokémon burrows deep into the sand and sleeps until sunrise.

Shield: Sandile is small, but its legs and lower body are powerful. Pushing sand aside as it goes, Sandile moves through the desert as if it’s swimming.
