The Blue Skull is a recurring class in the Disgaea series. The male equivalent to the Blue Mage, these hooded demons are able to cast all levels of Ice elemental magic. They have a weakness to fire magic in all games, like the blue mages, and are strong against red skulls and red mages. They are useful from the beginning of the game as they quickly learn spells which can be used to dispatch or weaken several enemies at once. The Class has weak defense and weak attack, but this is easily made up for by the high res and extremely high intelligence at higher levels. A perfect character to use to kill enemies from a distance, like all the skulls and mages. This character should always be equipped with at least one orb and the highest level staff affordable; some players choose to equip them with a Muscle (despite their poor aptitude for HP) to increase the damage they can take, and some equip them with some sort of shoes, as their move is relatively poor without them.

They retain their role from the original Disgaea, however, they have a slightly higher DEF than their female counterparts at the cost of lower RES. They are also competent with Swords and Spears at later levels.
