Generation VIII
Pokémon Sword and Shield

Alolan Marowak spins its bone and starts gathering purple flames in a circular fashion. As it does so, a blue aura flashes in the center of the circle. Then, it stops spinning the bone as the flames concentrate in one end of it before striking the opponent, creating a burst of purple and blue flames; or, Alolan Marowak spins its bone, lights its ends on purple fire, and strikes the opponent; or, Alolan Marowak holds its bone, which has both of its ends lit in a green flame, in front of it. Then, purple will-o'-the-wisps appear above the bone and enter the green flames, coloring them purple, before Alolan Marowak clubs the opponent, engulfing the target in purple flames.
