The treasures of ruin—Wo-Chien, Chien-Pao, Ting-Lu, and Chi-Yu—are a quartet of Legendary Pokémon first discovered in the Paldea region. They have been referred to as cursed treasures and Pokémon of Ruin. All of them are Dark-type. According to legend, these four Legendary Pokémon were once four ancient treasures, but were corrupted by negative human emotions. They came into the possession of an ancient king of Paldea. Eventually, the king's greed awakened them and unleashed disasters, resulting in these berserk Pokémon destroying the kingdom. All four were later sealed away in shrines by ancient Pokémon wielders after a fierce battle.
