Joachim was eventually killed when the " Reliant " faced the " Enterprise " in battle in the Mutara Nebula , leading Khan to swear that he would avenge his death . ( ) Appendices . Background information . Joachim was played by an uncredited Judson Scott . According to the , the character might have been intended to be Joaquin , who was Khan ' s deputy in . According to Scott , there were several scenes for Joachim that ended up on the cutting room floor . " " They had three scenes in the beginning where it ' s just Ricardo and me on the planet , about 20 minutes long . Dramatically , they might have made the right decision by cutting those scenes . But for me , that ' s the reason I took the movie : Montalban and I talk and read " Moby Dick " and the other books you do see in a quick cut in the final print . They were the books that Khan tutored me with – and that ' s all I knew about life and why I react as I do to Khan ' s inner battle with guilt and revenge . " " When asked what the exact relationship between Khan and Joachim were , Scott smiles and says , " " He was my Daddy . " " ( " " # 71 , , p . 15 ) The vest worn by Joachim in " Star Trek II " was sold as Lot # 821 at the auction . The buyer paid US $ 5 , 040 for the lot , after winning it with a bid of US $ 4 , 200 . The catalog , which listed the lot as " Joaquim ' s Vest " , estimated a price of 600 to 800 dollars . Apocrypha . According to Greg Cox ' novel " " , Joachim is the son of Joaquin Weiss and Suzette Ling , who were married after Khan and his fellow Augments were left on Ceti Alpha V in 2267 . After Joaquin and Ling both die defending Khan in battle , Khan decides to raise Joachim as if he were his own son . Khan felt this is the least he could do after Joaquin ' s many years of faithful dedication in service to him . Also noted in the book was the fact that most of the followers of Khan found on Ceti Alpha V by Chekov and Terrell were much younger than Khan . This is explained in the novel that within six months of exile ( shortly before the explosion of Ceti Alpha VI ) , many of the colonists had paired off and several of the women were already pregnant . These children were born in the underground caves following Ceti Alpha VI ' s destruction and , because of their genetically altered status , they seemed to mature much faster than ordinary Humans . For example , when Joachim was ten in approximately 2278 , Khan noted in his journals ( which were found by Kirk on Ceti Alpha V in 2287 ) that he appeared already to be fifteen . By the time of their escape aboard the " Reliant " , all but a handful of the original Augments from the Eugenics Wars era had died due to disease , combat , accident or infection by the Ceti eel s . Consequently , most of Khan ' s crew , which according to Chekov , was only about two dozen people , were the children born after the exile .
