The Warrior (also known as the Fighter) is a recurring class in the Disgaea series. Most males in the Netherworld can become Warriors, though one must make a pact with the God of War Grandell to take on the title. Warriors wear light armor, but can harden their bodies instantly as a defensive measure. They are aggressive wandering soldiers with a low capacity for friendship, but respect those they deem worthy.
