Blacephalon

Blacephalon (Japanese: ズガドーン Zugadoon) is a dual-type Fire/Ghost Ultra Beast Pokémon introduced in Generation VII, in Pokémon Ultra Sun and Ultra Moon. It is also known by the code name UB Burst. Blacephalon has a unique design, resembling a clown or circus performer with a detachable head that it uses to attack. Its body is primarily yellow with blue and pink stripes, along with white frills. Its head is a white sphere with colorful dots and star-shaped eyes. It tricks opponents by acting silly, then suddenly detonates its head, stealing their vitality. Blacephalon does not evolve and is known as the only Pokémon that can learn the move Mind Blown. It is a bizarre and powerful Ultra Beast that is not native to the standard Pokémon world.
