He is one of the augments from the Botany Bay. Klingons came across the ship, activated the Khan pod, and Khan died from cardiac arrest because the Klingons didn't bring a medic aboard. John Harrison is woken up, and he and his surviving augments take over the ship and set course for outside the galaxy. Once they cross the galactic barrier, everyone is killed except Harrison (who develops incredible powers different from Mitchell, because of his enhanced genetic makeup), and he takes the ship back to it's point of origin, the Klingon Homeworld. He kicks ass there, and the Klingons quietly ask for help from the Federation because of this human who is kicking their butt. Enterprise arrives, and Harrison lets himself be caught, and they take him back to Earth.
...And that's where things get REALLY interesting...![]()
But where does he find his android sidekicks who believe that Eartmen killed their Creators?
