Summary
The end of the world begins with the unrelenting anger of a boy who never truly grew up, and the desperation of another who wants nothing more than for them both to see a better future. While Izuku Midoriya hurtles towards the Coffin in the Sky and a fight he may originally have been destined to win, these two boys — brothers shrouded in fire and pain and bitter, bitter resentment — exchange blows that seal the fate of billions.
-
Izuku feels the blood drain from his face as he processes what it all means.
This is— this is impossible, but if he’s right then— holy shit, they have a chance, a real, actual chance, because if Uraraka doesn’t know him, and if she caught him when he fell, and if Eri’s quirk can rewind, rewind, rewind someone— something along its existence, then that can only mean—
“Today’s the Entrance Exam.”
-
Or:
Shoto's fight with Dabi goes sideways. This creates a ripple effect that decimates hero society.
Izuku's final confrontation with All For One saddles him with a ghost quirk. It, OfA and Rewind don't play nice — and Izuku finds himself back on the day of the Entrance Exam.
This time he'll make sure no one dies.

Summary
War had changed Hermione. Her idealism had been twisted into ruthless pragmatism in the face of death and destruction. Every day she questioned how far she would go to end the nightmare that had destroyed everyone she ever loved.
Being thrown back into the past into the lives of the Marauders would push her to her limits. Every moment she spent with them made her feel a little more alive, and less like the Serpent she needed to be. How could she learn to live with her choices in a world she was destined to die in?

What if the OG Trio were sent back in time? (Fire and Ice) by LuvvLucario
Fandoms: Warriors - Erin Hunter

Summary
The continuation of the first part of my what-if, covering the book of Fire and Ice.
This will spoil a LOT of things throughout the series, including how most characters die, and their relationships among other key plot points. If you don't care about that or already know, feel free to proceed. I'll be placing these in a series based on books, ie Into the Wild, Fire and Ice, Forest of Secrets, etc, etc. The major characters will also be referred to by their final names, such as Rusty, Firepaw, and Fireheart, being called Firestar regardless of what their actual names should be. The exception is when other characters are speaking to them.
Heavily inspired by The Amagi's Naruto series what-ifs of the same situation.
I own none of these characters or the franchise they're from, obviously.

Summary
Maul dies on Tatooine and wakes up over 40 years in the past. He quickly seizes the opportunity to change his fate and free himself from his Master, to save his brothers, including the one he doesn't yet know he has, and plot a new revenge against Darth Sidious with the advantages of time, foreknowledge and a surprisingly familiar Mandalorian face. It isn't only his own destiny that Maul's actions will change for the better, but that of Jango Fett and the entire Mandalorian people.
As far as the Force and the Ka'ra are concerned, healing hearts through the power of family and friendship will just be a nice side effect of saving the galaxy from its terrible future.

Summary
In the silence of the stars,
Two souls seek their path,
One dances to the breath of the winds,
The other paints the light with their hands.Between shadow and shine,
Realities bend and twist,
And in the symphony of colours,
A future yet unknown is forged.Series

Summary
What if Klay decided that being a married woman in this era was better than being branded as a loose woman who jumped from one man’s house to another?
What if instead of pushing to stay with Ibarra after she was thrown out of Maria Clara’s house by Padre Damaso, Klay took Fidel’s offer to stay at his casa, with an additional caveat - they would get married.
What if Maria Clara’s words to her struck Klay and she took it with a watpadder’s heart and decided to make her own fake marriage trope within the novel of Noli Me Tangere.
These are the consequences of her actions…

Summary
When the Battle of Hogwarts ended in defeat, the Golden Trio made a desperate, irreversible choice: to change the past. Ignoring Dumbledore’s grave warnings about the dangers of time travel, they gambled everything for a chance to save the people they loved.
They stopped Voldemort in 1981 — before the war ever truly began — and woke in a world that was both familiar and unrecognizably altered. Their memories of the original timeline remain intact, but everything else has shifted. The past was rewritten. So was their present.
But for Harry Potter, one truth still holds in this new reality: Hermione Granger is meant to be by his side.
*** I do not support any group that condones bully/bashing of Authors or their stories within their spaces. Fanfiction is free emotional labor, time, creativity, ect. Because of that, the way readers need to approach leaving feedback is different. We must be kind and supportive, or simply scroll on. Harmony spaces have been especially toxic to authors and as a shipping community we need to take a stand against such behavior. ***
