Black Hole Eclipse (Special) is a Dark-type Z-Move with varying power and 100% accuracy. It is derived from any damaging Dark-type move when a Pokémon is holding the Darkinium Z and has used the Z-Power. The power of Black Hole Eclipse depends on the base move it is based on; for instance, it ranges from 100 to 200. This Z-Move delivers a powerful attack that not only deals significant damage but also boasts full accuracy, ensuring it hits its target. Z-Moves like Black Hole Eclipse (Special) are a unique mechanic introduced in Pokémon Sun and Moon, allowing trainers to unleash a one-time powerful attack per battle, adding strategic depth to the gameplay.
