Star Trek Alternative Universes

TNG rejected plotline/AU where Alexander brings home the class Tribble for the weekend

AU where Terry Crews pitches all the AUs with him to Paramount or whoever and they all get merged into one TV show

An Alternate Universe where all ships have a Vulcan medical officer whose answer to everything medically is "I have to initiate a Mind Meld" before proceeding. All fellow medical officers, nurses, and staff roll their eyes in a "not again" implication.

First Contact AU where Worf tells Picard; "If you were a Tribble, I'd kill you where you stand"

An Alternate Universe where Miles, Keiko, Julian, and Kira all are in a complicated polyamorous relationship.

AU where Insurrection didn’t play out like like an TNG extended episode

AU where every Federation starship has at least one McDonalds, Starbucks, and Subway inside of it. Some have Orange Julius

All of the theme songs are replaced with Scooby Doo themes, and get similar opening sequences. DS9 gets Mystery Incorporated, and I guess TOS gets the original Scooby Doo theme, idk about the others

AU where it turns out that there are six Quarks. They call themselves Up, Down, Top, Bottom, Charm and Strange.

Worf's sash is actually a scouting sash covered in badges.

AU where each theme song is replaced with a hit song from the year the show came out -- Voyager's theme song is now "Gangsta's Paradise". DS9: "Whoomp! There It Is", TOS: "Paint It Black", Disco: "Believer" by Imagine Dragons. TNG's opening theme: "Never Gonna Give You Up"

AUu where they played the regular theme music at the opening of "In a Mirror, Darkly". It still has the altered video opening, though, so you've got "Faith of the Heart" playing over all the footage of military stuff

Au where Tribbles bounce- not all over the place like a ping pong ball but just more of a gentle bob.
