A monster is a type of class featured in the Disgaea series. Unlike humanoid classes, monsters can only wield Monster weapons, and prior to Disgaea 5: Alliance of Vengeance, are unable to gain Weapon Mastery. There are various monster classes, the most famous being the Prinny race.
Monsters have at least four unique techniques that they learn as they increase in level.
Almost all monsters in Disgaea: Hour of Darkness have 100% aptitude in the eight basic stats, which is not shared by the humanoid classes who have varying apitudes in stats, while in Disgaea 2: Cursed Memories and later games they have varying apitudes as the human classes do.
Despite the name, some humanoid looking classes such as the Succubus are actually classified as monsters. In addition, some appear to use weapons in combat, while in gameplay all monster classes only equip monster weapons with no exceptions.
