 Khan appears in the 2013 film Star Trek Into Darkness, taking place in the alternate continuity established in Star Trek (2009). While the character ’ s backstory remains the same, Khan is revived by Starfleet Admiral Alexander Marcus rather than the crew of Enterprise. Marcus anticipates a war with the Klingons, and forces Khan to develop warships and weapons for Starfleet under the cover identity of "John Harrison", holding Khan's shipmates hostage. These developments include advanced long-range torpedoes and the warship USS Vengeance.
