Summary
In 2280, Obi-Wan is just another person who has been kidnapped and enslaved in post-nuclear-war Las Vegas. His life is awful and he just wants it to end. He can’t give up though, not when the Casino Boss has control over his little brother, Anakin.
Time is running out for Obi-Wan and Anakin, and just as everything is about to get so much worse, good luck strikes. Two men walk in who can’t keep their eyes off Obi-Wan and promise to do what they can to free Obi-Wan’s brother. But their help comes with a cost: Obi-Wan needs to help them take down the rich, powerful men enslaving him. Obi-Wan isn’t afraid to lose his life for a good cause, he just didn’t count on giving his heart, mind and body to these men along the way.
Or, the post-Nuclear apocalypse AU where Cody and Rex are trying to be the best of men, yet they can’t quite keep their hands off a very vulnerable Obi-Wan.
(Loosely based on the world of Fallout, you do not have to know anything about Fallout to understand this fic.)

I'm quite flattered by the interest, but I’m not looking to make a comic adaptation of this fic. Thanks for understanding! -

Summary
War. War never changes.
The America of the 21st century was defined by war. War with rival nations, war with its neighbours, even war with itself. It ended the only way it could’ve possibly ended – in a barrage of atomic fire that reduced the world to cinders. Most of those who escaped the bombs perished in the nuclear fallout, while the rest were forced to rebuild from the ashes. But those wealthy or lucky enough managed to escape to enormous underground bunkers, called Vaults, where they would spend the rest of their lives safe from the perils of the wasteland.
For one of these vault dwellers, life is about to change. Forced out of her Vault against her will, she will confront cruel raiders, mutated abominations and mad psychics as she tries to navigate her place in the wasteland.
This is the story of Luz Noceda.

Summary
The wasteland is a lawless, lonely place. Who can blame a girl when a chance encounter leaves you chasing after a man who dreams of more than just scraping by in a shitty settlement? Although there might be something more dangerous than deathclaws roaming around out there...

Gamma: Memoir of the Wasteland by Thunderstorm_of_Destruction94

Summary
Before the bombs fell, Kat Witherspoon had her doubts. About the world. About the war. About the man she married. But it wasn’t until she stepped out of Vault 111 that she realized the full weight of what she’d lost—and what she’d never had.
Not a tale of vengeance. But a story about rebuilding, grief, about finding purpose in a world that’s already ended. A character-driven retelling of Fallout 4 with heavy emotional depth, slow-burn bonds, and echoes of a much older story—one about heart, courage, and the long road to where the real home is.

Summary
In this second part of the Alternate Fallout, we explore the Fallout version of Harry’s life, a darker version. This story will set things up for the future, if I progress that far, and show how the ending not only leads to the next part but also to the rest of Alternate Fallout. You can skip this if you wish, but reading the ending will help in understanding the story ahead.
I've rated this as Mature to be safe.

Summary
Seriously, it was all Bakugou's fault. If he hadn't pissed off the commission, then they wouldn't all be in some sort of Wasteland with no food, no water, and no quirks, completely helpless. Their class wouldn't be separated through time and space, and they wouldn't have to eat whatever the heck that just crawled into the fire. As corny as it sounds, they will have to work together to survive post-war West Virginia until after the commission forgives them. Until then, they are dealing with each other, the scorched, whatever radiation beasts are hiding in the hills, and someone who calls themselves Knight Errant, though they seem to know far more than they initially let on.
