Joaquin

From Memory Alpha, the free Star Trek reference.

Joaquin was a genetically-engineered Augment from Earth's 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. (TOS: "Space Seed")

Joaquin was played by Mark Tobin. In Greg Cox's novels about the Eugenics Wars, Joaquin was a faithful bodyguard of Khan and the father of Joachim, who was one of Khan's crew in Star Trek II: The Wrath of Khan.
