Summary
This is normal. This is all perfectly fine. Sure, Megatron's been more unpredictable than normal lately - more easily angered, almost as if he's only waiting for the slightest excuse - but it's fine. Starscream's been through worse. This isn't what's going to break him.
Besides...it's not like he has anywhere to go. -

Summary
Missions that involve infiltrating primitive planets are always tricky ones. When things go wrong, the Prime Directive can make rescue impossible. When Jim gets in trouble - because of course he does! - the question becomes not whether the Enterprise can save him, but whether they’re even allowed to try. Spock would give his very life to save Jim, but will he sacrifice everything Starfleet stands for?...

Summary
On his very first away team, Wesley was nearly killed by police, and Beverley could do nothing.
When Beverly was kidnapped she saw even more brutality first hand, and Wesley's attempts to find her had been hyjacked by the planet's police to hunt members of a resistance group.
**I thought both these episodes needed some retcons if their endings were ever to be even remotely satisfying**

Summary
This is Part 5 of my Star Trek saga. It follows “The Emptiness in this World”, so I recommend reading that one first for context.
When Jim, Spock, Bones, and Uhura beam down for a routine first contact mission, they expect the usual diplomacy and data gathering. But an unexpected encounter turns their visit into something far more thrilling and far more complicated than anyone could have anticipated.Series

Summary
After encountering yet another spatial anomaly and undergoing an event known as a Noodle Incident, the U.S.S. Enterprise-A crash-lands on a previously-undiscovered Class M planet.
After taking stock of their surroundings, the crew hastily work to get their ship up and running again, deciding that even the ability to stay in orbit of the planet would suffice.
After the Nusian Security Council catches wind of a UFO crashing in the plains of occupied Guesa, military forces are rapidly mobilized to secure the area and reverse-engineer any salvageable technology from the crash site.
Nusian drones have also picked up on the fact that there are survivors guarding the wreck, and while it is more than capable of overwhelming force, the Republic does not wish to risk losing its prize by smashing any possible resistance with the hammer that is the Nusian army.
They opt for the more surgical approach instead, deploying Fireteam-6 to get what they want.

Mariner the Apex Predator by FluffyLordoftheDead12 for FoeHammer
Fandoms: Star Trek: Lower Decks (Cartoon)
24 Mar 2025
Tags
Summary
The warp core four get stuck with Lt Jr Grade Castro on a pre-first-contact dieselpunk planet, ruled over by a not-entirely-benevolent god-queen with a taste for humanoid sacrifices. Castro should be taking the lead, but she's afraid of Mariner. Mariner is eager to take down the forces of evil, but it turns out when you defeat the god-queen, you become the new god-queen.
Overthrowing evil is easy; nation-building is hard.
This is a non-canonical spinoff of my fanfic, Hungry Hungry Mariner, but all you really need to know is that Mariner can vore people, everyone on the Cerritos knows about it by now, and she's in a relationship with Tendi while still being in a relationship with Jennifer. Written with care for my friend, Foehammer.
On the off-chance that you want to discuss this fic, we have a discord now! https://discord.gg/zKmNWSVGmE But comments are also a good way to discuss it. :)

Summary
Jim was kind of a Shakespeare fanboy. He’d read all of his plays multiple times, and could quote many of them by memory. So what did he do when on a Shakespeare themed planet? Try to piss off as many people as possible, of course!
Spock gave Jim a disapproving Vulcan side-eye. “Captain, please stop biting your thumb.”
