Joachim (also Joachin and Joaquin) is a genetically engineered character in the fictional Star Trek universe who appears as one of Khan Noonien Singh's henchmen in the Star Trek episode "Space Seed" and the film Star Trek II: The Wrath of Khan, in which he is played by Mark Tobin and Judson Scott, respectively. The official Star Trek site maintained by Paramount Pictures describes Joachim as a "genetically superior blonde-haired young man". The script for Star Trek II: The Wrath of Khan describes Joachim as "the largest and brightest of Khan's group". Name and identity In the text commentary for the Star Trek II director's edition DVD, Michael Okuda, co-author of The Star Trek Encyclopedia and a consultant on various Star Trek films and TV shows, points out that in "Space Seed", the character's name is Joachin (or Joaquin, according to the end credits of "Space Seed", as well as StarTrek.com) but that he was accidentally renamed Joachim in the film. In contrast, Greg Cox's non-canon novels The Eugenics Wars (Volume 1 & 2) and To Reign in Hell: The Exile of Khan Noonien Singh depict Joachim as the son of Joaquin and another SS Botany Bay survivor, Suzette Ling. In Cox's books, Joachim and the others who accompany Khan in Star Trek II were born in exile on Ceti Alpha V. Paramount Pictures' official Star Trek website maintains separate entries for Joaquin and Joachim. Portrayal Mark Tobin Mark Tobin played Joaquin in "Space Seed". He also played a Klingon in the episode "Day of the Dove". Judson Scott In Star Trek II: The Wrath of Khan, Joachim was played by Judson Scott. However, Scott's name does not appear in the credits. According to TV Guide, Scott's agent was in negotiations with Paramount Pictures to get Scott high billing, but the tactic backfired and Scott wound up with no credit at all. While this was one of several Star Trek roles for Scott, he: made his most memorable Trek appearance as Khan's son, Joachim, in Star Trek: The Wrath of Khan. Not only did he get a featured role in the best Star Trek movie ever, but he got to play opposite Ricardo Montalban. The two entered into a friendship which is still alive and well today. Recently, when Ricardo received a lifetime achievement award, Judson was the presenter. Scott also played a Brekkan in Star Trek: The Next Generation's
