Desco

Desco is a living weapon created by Nguyen Khan that was sealed in the Netherworld once she became "obsolete." She is convinced that she is the Final Boss of BZPB, and most of her motivation comes from striving to be an excellent villain. However, she's essentially been adopted by Zev Raregroove. It is unknown how this will affect her goal of becoming an excellently evil Final Boss.

Biography
Desco is normally very upbeat and hyper, and prone to acting on impulse. She also has equivalent emotional control to a small child, easily being driven to temper tantrums and crying fits. Her driving motivation is to become a Final Boss worthy of BZPB; she's even studied from textbooks on the matter! While Nguyen Khan abandoned her, calling Desco "obsolete" and "useless," Desco still refers to him as "Daddy."

History
Desco was created by Nguyen Khan at an unknown point in time. He raised her to become a "Final Boss" - that is, a being capable of eradicating anything that stands in its way. However, other breakthroughs in Khan's research made Desco obsolete, and as a result, he imprisoned her in a cell of his own design in the Netherworld.

When Fenrich took Zev, Namah, Aisha, Yoruichi, and Hilda to the Netherworld, they came across Desco's cell, which was in the process of opening. Khan addressed them from a screen attached to the cell and explained that he had chosen to free the "Prototype" because she did not belong there. He gave no explanation for his change of mind, but told the group that he cared not what they did with it. Desco emerged from the cell and, after being laughed at by Aisha, blasted her with a beam of energy, causing the rest of her group to attack her. Desco put up a good fight, but was eventually beaten into submission and began to cry. She revealed to Zev her treatment by Khan and intense fear of being abandoned again, which warmed the Juraian's heart so much that he decided to adopt her.

Her current location is unknown, but it is likely that she is being kept somewhere safe by the Conquistadores.
