demoniacal
Like Satan's servants
Demoniacal means of or resembling a demon—fiendish, frenzied, or seemingly possessed by evil spirits.
The word describes behavior or expressions that suggest supernatural malevolence or wild, uncontrollable fury: a demoniacal laugh, demoniacal energy.
It's the more literary variant of demonic, carrying an old-fashioned, Gothic flavor suited to horror fiction and dramatic description.
