3. Starfleet Officers Instigating War With The Klingons
The Enterprise seemed to always have run-ins with the Klingons throughout the Original Series, but these skirmishes were more minor incidents of a cold war than all out bloodshed. With Star Trek VI's destruction of the Klingon moon Praxis (also seen in Into Darkness, in orbit around Kronos) finally bringing both powers to the negotiating table however, there were those on both sides who weren't exactly thrilled at this prospect. Kirk and McCoy are sent to a Klingon penal asteroid for the assassination of Klingon High Chancellor Gorkon, and in what is essentially a murder mystery whodunnit in space, it is up to the crew of the Enterprise to discover who the real culprits are, and prevent them from further disrupting the peace talks. Assisted by Captain Hikaru Sulu (sound familiar?) of the USS Excelsior, the crew of the Enterprise obviously do manage to stop all of the actual perpetrators - both Starfleet and Klingons officers, and even a Romulan ambassador - and save the day. And possibly the galaxy. Big cheers to both crews all round, but it wasn't the first appearance of Sulu's eventual command....
