Jayo Cho-Leem was the youngest child of Thracia Cho-Leem and Jayo Chev'ris, and the brother of Rosala Cho-Leem, born in 27 BBY. Jayo was known for his enthusiasm, though was occasionally detached. He would sometimes say something wise, yet obvious, unexpectedly. Raised on Coruscant with loose connections with the Jedi Order, Jayo and his family was kidnapped by Separatist agents when he was seven years old and was given to the custody of Count Dooku, who killed his father. Later, they were rescued by the 1337 N00B5.
