Joachim was a male Augment who served under Khan Noonien Singh in 2285. That same year, he helped to escape Ceti Alpha V then commandeer and control the USS Reliant for Khan. (TOS movie, novelization & comic adaptation: The Wrath of Khan, ST website: StarTrek.com)

By one account, Joachim had been born on Ceti Alpha V, the son of Joaquin Weiss and Suzette Ling. When his parents died, Khan honored his old friends by raising their son. (TOS novel: To Reign in Hell: The Exile of Khan Noonien Singh) By another account, Joachim had been one of the Augments held in stasis on the SS Botany Bay, landing on Ceti Alpha V in 2267 and serving as Khan's lieutenant during their exile. (TOS comic: "Khan: Ruling in Hell")

Another account stated that Joachim was the offspring of Joaquin and a normal human female named Talia, and he was born before Khan's departure from Earth. When Khan was forced to flee in 1996, Joaquin and his son Joachim accompanied Khan on the SS Botany Bay. Because he was an Augment/normal hybrid, Joaquin faced significant discrimination from full Augment children. (KHA episode: Paradise)

Joachim was killed when the Reliant took heavy damage from the USS Enterprise. As Joachim lay dying, his final words to Khan were "Yours...is the superior..." Khan was enraged at Joachim's death and swore to avenge him. (TOS movie, novelization & comic adaptation: The Wrath of Khan, ST website: StarTrek.com)

Joachim was played onscreen by actor Judson Scott.
