The Hidiacs are the undead soldiers that serve Necrolai, and all other evil forces. They are equipped with blade weapons and can fire explosive plasma. The majority of the Hidiacs is destroyed when Leanbow "destroyed" the Underworld in "Heir Apparent" Part 2. The surviving are destroyed in "The Hunter".
- In the Power Rangers Mystic Force toyline, the Hidiacs are referred to as 'Evil Space Alien', instead of of their proper name, despite not being aliens from outer space or have anything to do with Rita and Zedd's group of villains. This is because 'Evil Space Alien' is a general term used by Bandai when releasing villains before they are explicitly named in the show.
