Shadow-Sky is a Flying-type move introduced in the series. It has a unique aspect where it alters the battlefield conditions rather than dealing direct damage. When used, Shadow-Sky creates a dark, turbulent sky for five turns. While active, this weather condition boosts the power of Ghost-type moves and has certain interactions with specific abilities and moves. However, it does not have any direct accuracy or power statistics because it modifies the weather. This move stands out for its strategic benefits, making it highly valuable in competitive play to create advantageous conditions for Ghost-type Pokémon and to disrupt opponents relying on other weather-based strategies.
