Hudzen-10 was the last known line of model, and the most advanced, of the service mechanoids built and supplied by DivaDroid International. One particular Hudzen-10 became the only known mechanoid to have gone rogue, murderous and insane, a trait usually seen in Simulants. This was the individual which was intended to replace his predecessor Kryten, whom he spent three million years tracking from the Nova 5 to the Red Dwarf.
