Udo Karr was a human Jedi youngling that survived the attack on the Jedi Temple, through the efforts of Nathaniel Kenobi. He accompanied him and his fellow Bothan youngling Ada Fey'lya to Kamino. Later in his life, Udo would marry Ada and have a child with her. After Nathaniel left the colony, Udo became a prominent member of the order, until he was slaughtered by his own padawan during the Great Schism.
