The Professor is a recurring humanoid class in the Disgaea series first introduced in Makai Kingdom, then in Disgaea proper in Disgaea 4: A Promise Unforgotten.

Characteristics
Professors are demons who have taken an interest in human science and technology and are now studying in the field of Netherscience. Though the profession is rare at the moment, Netherscience is a constantly expanding field with many unproven areas. Professors are eternal searchers of truth, making them comrades with the Magic Knights. They are actually quite skilled in the art of modifying the abilities of others.
