Emperor Yuri acquired his nickname by virtue (or vice) of being an extreme paranoid who was so worried about others stealing his power that he sent death squads to kill everyone within the Imperial Blood Line. Aral Vorkosigan witnessed Yuri's death squad execute his mother and other relatives when Emperor Yuri sent a squad to kill the Vorkosigan descendents of Prince Xav, Yuri's half-brother.

Following the murder of Aral's mother, Aral's father, Count Piotr Vorkosigan, joined forces with Ezar Vorbarra in opposition to Emperor Yuri, beginning what would become known as Emperor Yuri's Civil War. When Yuri was finally captured, Ezar orchestrated an elaborate execution for him in which the principal members of the insurgence collectively dismembered Yuri, with young Aral striking the first blow.

- Reign (unknown till Aral Vorkosigan was roughly 13 years old.)
