Joaquin was a genetically-engineered Augment from Earth's late 20th century, a follower of Khan Noonien Singh and survivor of the Eugenics Wars. Joaquin escaped Earth aboard the SS Botany Bay. In 2267, the USS Enterprise discovered the Botany Bay, on which Joaquin was one of the 72 surviving members of Khan's original group of 84, excepting Khan himself. When Khan revived his people on the Botany Bay and brought them to the Enterprise with assistance from Marla McGivers, he informed Joaquin that the battle had begun again, only they'd win more than a world. They'd win a universe.
