The Succubus is a monster unit that has appeared in all five Disgaea games. Succubi are one of the few monster units in the Disgaea series that have an innate healing ability. Powerful and beautiful, Succubi live by seducing men and it is doubtful that any can resist their power. They get along with Nekomatas.

In the original Disgaea, Succubi, as evident in Chapter 5, are one of Laharl's big weaknesses, being very busty. Their abilities include both physical and magical ones. In the remakes, a Succubus named Antoire joins Etna's group in Etna Mode.

In Disgaea 2, Succubi first appear in chapter 5, in the Cavern of Evil. Their innate ability is to deal more damage against male opponents. They also have a high INT, which makes them one of the best monster casters in the game.
A Succubus named Elenor has a small history with Adell, as he went to her to find out more about his parents. However, she tricked him and nearly killed him, which resulted in the scars on his face. She later appears in Chapter 6, but was defeated by Adell.

In Disgaea 3, Succubi recieved a redesign, looking more slender. Their evilities have been changed around to give them a higher advantage against males, cutting their stats when in 1-panel range and receiving less damage. They are also a group in the Classroom Assembly, with their preferred bribery item being belts, although sweets also secure the deal. They vote favorably toward males.

Succubi are flying enemy who harry the Prinnies with heart-shaped attacks, mainly bombs (with lit fuses), but on occasion also throw out a large heart-shaped blast of energy that homes in on the Prinnies. In this game, there also appear Liliths, who appear to be younger versions of the Succubi, but in reality are actually incubi.
Succubi and Liliths reappear as enemies in Succubi Tower along with a new version of Succubi called Lillims that sometimes teleports around and often attack nude (but covered) with bats that homes in on the Prinnies.
