Shadow Break is a Shadow-type move introduced in Pokémon XD: Gale of Darkness. It has 75 power and 100% accuracy. This move is unique as it is exclusive to Shadow Pokémon, which are corrupted by darkness and typically only appear in certain Pokémon games, notably the GameCube titles. Shadow Break has the distinct feature of being super effective against all non-Shadow Pokémon but is less effective against other Shadow Pokémon. It also causes recoil damage to the user, dealing damage equal to one-fourth of the damage inflicted on the target. This move is part of a broader mechanic in these games, where Shadow Pokémon can be purified through various means, after which they can no longer use Shadow-type moves.
