Hidoi (ひどい Hidoi) are the main monsters in Season Heart Pretty Cure!. They are created when a commander of the Dusk Area shoots a Shard of Darkness into a human's neck. The commander then shouts, "Come forth, Hidoi, and release the evil in your heart!" and the human is then turned into a Hidoi. When they are defeated, they say "so relaxing".
