The appearance of Succubi heavily bears a shape of attractive female humans and are completely nude. They have hind legs faintly resembling of goats, reddish lizard-like tails, vampiric fangs, and inhuman-looking arms possessing similarities to Onoskelises. On their backs is a pair of bone-structured stumps as if their wings are torn off.
Succubi also comes in many different varieties, with different-styled horns and appear with or without hair. Some even appear with their bodies covered with paint-markings made with blood.
The Succubi are seductive and lustful female demons that enjoy the suffering and sexual activities from both humans and demons. They are very manipulative and violent, as told in the notes throughout the story, they eat their victims while giving the victim "great pleasure". They also preform a lot of orgies, and is mostly filled with women and barely to no men; It is unknown if they prefer women or that they lack demon men in hell. In that case, their male equivalents (accurately known as Incubus) are nowhere to be encountered.
It's heavily implied in Agony that succubi are formed from the souls of those who served as the Red Goddess' priestesses in life, who now serve in Hell in a similar role, seducing men with the intent of devouring them just as how in life they seduced men only to enslave them in service to the goddess. Like all other souls in Hell, they possess few if any memories of their time on Earth.
In the Succubus Prologue bestiary, it's stated that the first, and presumably a number of subsequent, succubi were created from the souls of female sexual abuse victims, and that compared to other demons of Hell, they're a relatively new species, leading to resentment.
- A Succubus is a demon in female form, or supernatural entity in folklore (traced back to medieval legend), that appears in dreams and takes the form of a woman in order to seduce men, usually through sexual activity. The male counterpart is the incubus. Religious traditions hold that repeated sexual activity with a succubus may result in the deterioration of health or mental state, or even death.
