Alternate Star Trek History? Ooh boy there is a lot, even discounting the ones that were covered on the show.
1.)Star Trek IV. Kirk, McCoy and company get caught trying to rescue Chekhov from the hospital. Eventually the Bird of Prey is found. Earth History is changed a lot as a result from the Klingon Bird of Prey.
2.)Star Trek VI. The conspiracy goes through, the Klingon-Federation cold war continues.
3.)One I would have liked to see is if that Klingon didn't crash on Earth in 2151. Archer might not have been captain, T'Pol would not be a science officer.
4.)The Original Series. The Organians did not intervene, and the Klingon-Federation War starts.
The Next Generation: Three ideas here.
5.)One, Troi never crashed her shuttle in Season 1. Lieutenant Tasha Yar remains as security Chief. Imagine the results when Sela is introduced, "Hello Mother, It's been a while"
6.)Two, Cmdr. Riker accepts a post on the Melbourne and dies at the Battle of Wolf 359
7.)Three, In Season 7 Crusher and Picard start a romantic relationship after "Attached"
8.)Deep Space 9: Sisko doesn't see the Prophet, and DS9 remains in orbit of Bajor. How would the conflicts of the show resolve without the Dominion, or the wormhole being discovered?
9.)Voyager: Well one obvious one. Voyager doesn't get lost in the Delta Quad.
10.)More subtle, Bleana and Seven are able to figure out Quantum Slipstream.
11.)To make the series darker, the Think Tank offers Janeway a way to get home immediately, if Seven joins. Immediate results, Seven might volunteer for it, she has no family back on Earth, and her few friends on Voyager would reach home immediately if she sacrificed herself for her new collective.
More non-series PODs
12.)Romulans win the conflict on Vulcan, Vulcans are unified but with a militaristic expansionist edge
13.)Praxis explodes, but its the Romulans that bail out the Klingons, and they then ally together against the Federation.
14.)Ferengi are the ones that make first contact with Earth in 2063.
15.)No Treaty of Algernon. Federation has cloaking devices. Not only that but the Phased Cloak from "The Pegasus"
16.)What should have happened in Nemesis? No Argo, No B-4, No Shinzon.
1.) That would be very interesting! I can imagine that the Cold War is going to go on a while longer, that the whales will be made a priority for conservation, and that we will be the ones to land on Vulcan and not the other way around.
2.) See the episode of TNG where Guinan guides Picard to make a better choice with regards to the Enterprise-B or was it C?
3.) Interesting idea, how would that change the Temporal Cold War? (A war that always bugged me for its obvious problems)
4.) You would have to change what the Organians were doing really to make that happen I believe.
5.) Obviously the creature would never be discovered, Worf would probably transfer to another ship. I do not believe we would meet Selar as it creates a change in the time-incursion, or whatever you want to call that paradox.
6.) That really creates some big changes that would be hard to calculate without a lot of looking back into the series.
7.) Little baby sooner, and less desire and heartbreak if at all (meaning his family may not die in this timeline) when his brother and his nephew die in the fire. Changes events during the movie Generations.
8.) That would really change a large section of history. It would also leave less devestation and appearance of a depression inside the Federation for when the Borg come the second time.
9.) No series....
10.) Different homecoming and less Borg improvements. Probably more worlds destroyed when the Borg regroup and hit the Federation.
11.) Ouch, but still not as dark as what I think of SGU.
12.) No Terran Empire/Federation, it would be a Vulcan Empire! Klingons and humans may form an alliance instead if we are not immediately annexed after first contact. Andorians may also be part of the Federatio/Klingon alliace or whatever happens here.
13.) Why would they? They do not see advantages like that often. They would rather subvert people or act behind the curtain to meet their ends.
14.) Ferengi are far away, they would be our first aliens, but I see no alliance or anything beyond that we know they exist. Vulcans are the best thing to happen to us.
15.) Big boost to what we can do, and probably faster improvements has the Federation as a free thinking people have more advantages than the Romulans IMHO.
16.) Oh Nemesis, you destroyed the Romulans.
No Typhon Pact if there is no Shinzon.
