Never-Ending-Nightmare--Physical is a Ghost-type Z-Move with its power varying based on the base move it is formed from. The move targets a single opponent and essentially retains the accuracy of the base move. Never-Ending-Nightmare is unique as it can cause devastating damage when used in conjunction with a high-power base move like Shadow Claw. To perform this move, the user must hold a Ghostium Z and have a compatible Ghost-type physical move. This Z-Move is known for its dramatic visual animation and substantial increase in power, providing a strategic edge in battles by potentially overwhelming the opponent with a powerful ghostly attack.
