Summary
Death should have been it. The End. Game Over. Instead, I was given a choice, quite a few choices actually... DxD was not the worst place to build a new life, a quiet life. I could just let the main cast deal with the world-ending troubles like they did in canon... wait, what do you mean crossover?! What do you mean the War in Heaven will restart?!
Follow this new story in the world of High School DxD, where power alone is never enough. Between the politics of devil society, the dangers of fallen angels, the schemes of the church, and the secrets buried in other worlds, Zyras must carve out his place in a universe teetering on chaos, with the shadow of God's return looming ever closer.

Harry Potter and the Mirror of... Noitcifnaf Enasni? by D_M_Nealey
Fandoms: Harry Potter - J. K. Rowling

Summary
Harry and Ron find and look into a very different mirror that Christmas holiday...
A collection of Harry Potter–themed one-shots and fanfic ideas that never went anywhere. Some are parodies, some were originally written for Reddit prompts, and some are half-finished stories that started strong but collapsed the moment I realized I had no idea what came next.
A fair few are just parodies or half-parodies that shouldn’t be taken too seriously. Harry and Ron certainly aren't going to!

Summary
They were told you were "An enigma from beyond the stars. An anomaly too lovely to ignore."
After all, in a universe so vast and infinite, there's bound to be some incredible anomalies out there somewhere. And you happen to be one of them. But what that exactly means... is up to all of them to figure it out.
As a huge fan of two of Hoyoverse's biggest and most beloved games, you find yourself using lore and characters from both as a means of escapism from your own dark, wretched world.
And after a various sequence of otherworldly events (courtesy of a cheery pink haired elf) you find that the cast of Genshin Impact have suddenly appeared in your house as you arrive home from classes.
Where they refuse to explain how they got there and why...
₊˚ ✧ ━━━━⊱⋆⊰━━━━ ✧ ₊˚
🫧Technically Reverse Isekai. But a crossover between Genshin and Honkai Impact. As the Abyss Order and the Honkai are key plot points.
🫧This is currently being edited, somethings may be different than the original
🫧Any events that appear similar to ones occurring irl are intentional and I have no shame to say it how it is.

Summary
Out of everything God has created, Humans are the most unique due to them gaining the ability to think like God, allowing them to have a vision of what they want to see, plan to achieve in making the vision, and ultimately, with enough time and effort, make the dreams they wanted come true. They lack God's power, however, and thus are incapable of simply creating something trough their own mindpower.
...Right?
Nobody has realized that far, FAR away from here, an anomaly that is beyond anything ever created has been unleashed and is making the rounds on the many worlds that it sets its sights on, causing havoc and destruction wherever it goes. The only one who can stop them is their own creator, who would definitely agree to set things right before his home is next...
if he wasn't so shy and hesitate about this situation, or too weak to start.But at least the unbelievably obscure cast that nobody would make the main characters of any massive multiplayer crossover of that are also the creator's favorites are here to help out, if they can get along, that is.

Tags
Summary
Dimension J-316 is home to angelic warriors of different kinds, tasked with protecting the Multiverse from threats in other dimensions. With the Archon Demons, and now Tarsa, free to cause destruction, every angel is on the fight to stopping these threats. One angel, Michael Celeste, finds himself meeting a team of Multiverse Heroes going by the name "The Sharp Gang" and offers his assistance.
As it turns out, the group has a few familiar faces for him. Some he's happy to see, some he's not... and one that's angry to see HIM. Turns out Michael has a past with one Jake Tagen that left the latter feeling furious with him, and the group starts to see just how much pain the young healer is actually dealing with... not physically, but mentally.
Multiverse Tales is a series owned by Christian Pearson, and most characters involved belong to him. This is in no way canon to Popcross Studios' actual canon of Multiverse Tales, and diverges after "Tarsa’s Archon Reunion".

Summary
After spending his entire life tirelessly dedicated to medicine, our protagonist dies with the deep regret of never having fulfilled his dream of becoming a doctor and, above all, not having enjoyed his life. However, fate grants him a second chance by transmigrating his soul into the body of PJ Duncan, a teenager who has just moved with his family to a small town in Texas.
In his new home, PJ finds himself surrounded by unique characters who will change his life forever. Among them is Sheldon Cooper, the genius son of the neighbors, whose intellect defies everyday logic. Additionally, PJ meets the enigmatic and brilliant Dr. Gregory House, a doctor whose unconventional skills and methods inspire him to pursue his old dream.
In this new life, PJ must not only adapt to his environment and understand the dynamics of the Duncan family but also face the challenges of adolescence while trying to make the most of this second opportunity. With his previous knowledge and new friendships, PJ has the chance to rediscover the meaning of living fully and, perhaps, finally become the doctor he always wanted to be.

Summary
In which a GF-fangirl wakes up to find herself in the body of a baby Bill Cipher before the events of canon happens. Welp, lets see how much she can fuck this up.
(Updates once every other week)
(Now canonically a shared universe with the Triplet AU, Dimension 46'/-A and One Way(to absolve his crime))
IMPORTANT NOTE: Ok, so I've decided to just put a warning right here about BlueBill from Dimension 46'/-A. He's not a good person, and is going to trigger a lot of people. Also putting up an angst warning for when things get super emotionally draining as a result of BlueBill and other terrible things making MizBill spiral into depression.
This is backstory, character exploration, slice of life and very much a cradle to the grave sort of thing. And... apparently the romance is finally coming up. Woop?
This is not meant to be taken seriously, it's just a stupid idea I'm writing for fun.Series

I own nothing but this fanfiction, Oneshot is created by Future Cat LLC, and I plan to have multiple crossovers. I die and end up with some powers, so of course I would use them to visit worlds, cause chaos and shenanigans and visit people that I missed dearly. And maybe also save some worlds, or at least give them a better ending. TLDR: Just a below average SI fic
