Chandelure also uses Will-O-Wisp in Pokkén. Chandelure sends weak purple flames that either fly forward or remain in place if charged. The flames cannot be nullified by other projectiles, and upon contact, the opponent's Attack is lowered, similar to a burn.
Chandelure floats up to the opponent and starts spinning its body around. It then releases multiple light blue fireballs from its body at the opponent, or Chandelure starts spinning its body around and a light blue fireball forms in front of its body where it was facing before it started to spin. As it spins, the fireball grows bigger, and it launches the light blue fireball at the opponent. As it flies through the air, the fireball becomes surrounded in purple fire.
Mega Banette forms a fireball that is colored white, light-blue, purple, and dark-purple, in front of its mouth and two hands, it leans back a bit and then throws the fireballs at its opponent and they follow the opponent as they move.
Despite what its name would imply, and it being more closely associated with Ghost types, Will-O-Wisp is a Fire-type move. This is presumably due to it inflicting a burn. A similar situation occurs with Poison Powder.
Will-O-Wisp is the only status move capable of inflicting a burn.
Even though Will-O-Wisp is a status move, its depiction in the anime is similar to that of a damage-dealing move, never causing any burns at all, in one instance being shown to equal Flamethrower in terms of power.
In the dub versions of Jirachi: Wish Maker, when Butler calls for his Dusclops to use this attack, he calls it "Capitata" rather than "Will-O-Wisp". In the Japanese version, Butler says 'Onibi!' which is Will-O-Wisp's official Japanese name. It is unknown how the name "Capitata" got into the script or final product.
