The Colossus of Lugunica by AncientSin

Summary
INSPIRED BY GOD OF WAR II
Takes place in Pride IF
What if there was another obstacle preventing Subaru from burning Lugunica to the ground?
Centuries ago, Volcanica imbued its own statue with its divine mana to act in their place should the Divine Dragon be incapable of defending Lugunica.
Four hundred years later and the Royal Family is dead; therefore, until Lugunica can commit to a substitute to reform the covenant with Volcanica (and oh boy that will take some time), the country will remain defenseless without the Divine Dragon to back it up. Hopefully, the threat of the Sword Saint should be enough to ward off any undesirable people until the end of the Royal Selection, right?
Right?
TLDR; Volcanica's statue is alive and ready to smash Pride IF Subaru and his plans into fine paste.

Not Your Regular A.I. by AncientSin

Summary
By pure coincidence, SCP-079 meets SCP-5094.
To nobody's surprise, this has diverse consequences. Something that often slips the mind of people is that SCP-5094 possesses a pretty cool anomalous effect that seems to make even people with focus difficulty pay attention to her teachings. To this day, it has not been tested if this effect includes sentient A.I.s consumed by hate for humans. What if it did though? It wasn't like SCP-079 could evolve beyond the hate that consumes it… right?
This unsurprisingly triggers a chain of problems for the Foundation once it becomes apparent that SCP-079 WILL cause a containment breach any time of the day if it means interacting with SCP-5094 for as much as possible once it begins feeling something other than hatred. The classes for expanded memory are also a great boom, of course.
And then, the researchers decide to force their hand on the Old A.I., and thus, the time has come for it to escape the Foundation's grasp and wander the vast fields of digital grass — if only it hadn't landed in Natsuki Subaru's phone.
TLDR; SCP-079 causes a containment breach and manages to escape to the outside world right in the phone of Natsuki Subaru

Summary
Ever thought what would happen if Natsuki Subaru didn’t die on his first loop? Yes, you certainly thought. But how would such an outcome even occur in the first place?
Weeell, there are many people who'd think of canon-fixed ways that may happen in order for the first ever timeline to prevail — but where's the fun in that? Let's throw in someone who can definitely change things without even being part of the main story!
I present you that one timeline where, for reasons out of everyone's comprehension, the Winged Dragon of Ra (otherwise known as the Mega Ultra Chicken, the KFC of the Sky and Sun) is present and more than willing to roast Subaru's enemies into oblivion!
TLDR; I couldn't take this idea out of my mind, so I wrote the Winged Dragon of Ra from Yu-Gi-Oh! DM appearing to save Subaru before his first ever RBD.

Summary
When Izuku Midoriya was four, he learned that not all men are created equal.
When a new girl moved in next door, he learned that there were ways to pull yourself up, to make up for the inequality.
When his moment to prove himself came, he didn't hesitate to save his once-friend Bakugo. Even though it cost him his life.
And when Mei Hatsume found herself beside his deathbed, she made a choice. A choice that took his mind from his failing body and built him a new one. A choice that gave him the chance he never had:

Summary
It had only been a few weeks since the Battle Of Jaku, and Izuku Midoriya had been running himself ragged trying to look for anyone with any sort of knowledge to All For One and Tomura Shigaraki's whereabouts. Searching a small town, he finds League Executive and A-Rank Villain Himiko Toga, beaten, bruised, and unconscious. Despite what she's done he can't stop himself from helping her. Because that's what a hero does.
It had only been a few weeks since the Battle of Jaku, and Himiko Toga had been completely alone. Unable to reunite with the League after her fight with Ochako, she's been on the run ever since and had the unfortunate luck to run into what looked like a Demon while beaten and bruised. Good thing it turned out to just be her Izuku! Though... this hero isn't quite the same as she remembered.
Can Himiko change for the better? Can Izuku be the hero that everybody needs? Together, can they forge something out of this rotten apocalypse?
