Alolan Marowak is a dual-type Fire/Ghost Pokémon.
In the Alola region, Marowak was faced with an abundance of its natural enemies, Grass-type Pokémon. This harsh environment led it to bond closely with its friends, which is said to have created a sort of sixth sense and caused it to take a new form. Alolan Marowak's body is black and it has pale gray eyes. There is a dark, flamelike mark on its skull between the eyes. Compared to regular Marowak's squatter, thicker body, Alolan Marowak is relatively thin. White markings resembling shoulder blades, vertebrae, and hip bones are visible on its back. The bone Alolan Marowak uses is longer than the one regular Marowak uses. It customarily mourns its companions by burying them and dance in mourning.
Alolan Marowak rubs the bone it wields against its forehead to light the ends in a green flame, and then twirls the flaming bone. It specializes in an attack where it releases a weak ball of flame from its bone that will relentlessly pursue its foe. Alolans would fear it for a conjurer, due to its rarity and the fearful sight of it dancing with its bone. The dance is also used as a way of mourning for its lost allies. Once its flames have spread onto an opponent, they are impossible to put out with water. The flames are known to cause both mental and physical pain. Alongside retaining the ability to learn Bone Club and Bonemerang and use the Thick Club, Alolan Marowak is the only known Pokémon that can learn Shadow Bone.
