Shadow Half is a Shadow-type move with 0 power and 100% accuracy. It reduces the HP of all Pokémon in battle, including the user, to half of their current HP. This move is exclusive to Pokémon XD: Gale of Darkness and cannot be used outside this game. It has no effect on Pokémon with the ability Wonder Guard. Shadow Half is particularly notable for its tactical usage in double battles, where the user might aim to synchronize its effects with other strategies.
