Desco, short for Death/Extermination Submersible Combat Organism, is the prototype version of DES X and a man-made demon created by humans to be the ultimate weapon in Disgaea 4: A Promise Unforgotten. Left in Hades and sealed away to be contained, Axel released her in the hopes of commanding her to do his will. Unfortunately for Axel, she vaporizes him before being defeated by Valvatorez and begging to not be left alone.
Desco's dream is to become a final boss and is usually upbeat and excitable. She is heavily attached to Fuka, calling her "Big Sis", and along with Vulcanus the three often form a gossip circle. She sees Valvatorez as a mentor, often running to him when something goes wrong, but is afraid of Fenrich, often hiding behind Fuka when he is near.
