I'm trying to come up with a time travel scenario for a story I'm writing, and I would like some suggestions.

They travel back in time to stop a horrific historic event thats about to happen. Somehow, in the present time, the past changes itself and they have to go back and fix it. Someone is taken to the past and trapped there.

I think that happened before.

Someone travels back in time to stop the invention of the time machine, and are somehow caught in a massive paradox, seeing as they can't go back to stop it if the machine was never invented.

I've always been partial to the idea that if you travel to the past, before the time machine was invented, it doesn't go with you and you become trapped.

Don't do time travel.

…

But if you do, make the logic unquestionable.
You need a 'Flux Capacitor'
Something vague enough that you don't have to invent time travel just to figure out an explanation, but specific enough to sound like it could be a thing.
Glowing, unexplainable things are a staple of sci-fi. We don't know how they work, but we know they do something.

You could do something where one character goes back in time to save the life of another character, but in the midst of everything, a different character dies.

Write about an assassin who is a master of the butterfly effect, and kills peple by going back in time

I do enjoy the one where someone goes back in time to save a family member or a friend or just lots of people, but then because they saved all these people that were supposed to die, someone else dies or another big thing happens that you can't control.
Also since people's immune system's strength and how it works changes over time to adapt to certain viruses, it's said that if you went back in time you'd kill everyone because they can't fight against any bacteria on you, but if you went forward in time you'd die because you aren't immune to the same things those people are. (kinda like the aliens in that one classical book I had to read in middle school and I'm blanking on the name now, but where the aliens could kill the humans just fine but they died because of the bacteria and germs and stuff)(war of the worlds? idk sorry).
