Darth Kalos, born Rady, was a male Human Sith, son of Rocky. He lived a relatively solitary childhood on Nar Shaddaa, despite receiving a large amount of love from both of his parents. He felt that they did not love him enough, however, and this sentiment made it all the easier for Commander Fed and Darth Vader to exploit him into joining the Sith. He was employed by Vader and Palpatine to kill as many of the Jedi survivors of Order 66 as possible. He fought with Ricky Seneria during Ricky's Rebellion. During the Battle of Fondor, he was terribly mauled by Seneria after a terrible explosion.
