Summary
Bred to be humanity’s Messiah. Betrayed into becoming its greatest Demon. Kai Stormborn died after exacting revenge.
But death could not claim him.Reborn in the Primordial Tower. He carries a Glitch — a forbidden anomaly that lets him devour magical creatures, assimilate their abilities, and evolve.
To ascend beyond mortality, Kai must consume worlds, crush their champions, and rewrite their fates.He bends the Harry Potter timeline to his will. He manipulates the Great Houses of Game of Thrones like pawns. He fuses the very realities of Demon Slayer, Bleach, and more into his domain. His Breathing Style warps the laws of Reality Marbles. His mind becomes an Artificial Intelligence. His spirit wields the Will of D.
Dumbledore fears him. The Akatsuki hunt him. The Gotei 13, the Warlords, the Jedi—all have stood in his way. All have fallen.
Corpses stack like monuments in his wake and Timelines fracture as he upends the lores of the worlds. He does not follow Chaos. He does not obey Order. He bends Reality to his will.
This is not a story of redemption. It is the legend of a demonic being who rewrote the rules of existence itself.
But can you stomach what comes next?

Summary
Alan flees many things—death, his actions, and a past he doesn’t quite remember. Meanwhile, Gaipa chases his duty, his righteous cause, and a future he just might prevent. When these two meet on a battlefield across time itself, their shared past and destined future will finally catch up to them—and the fate of the whole world hangs in the balance.
Or: Join me as I attempt Whumptober in the most *me* way possible by stringing all the prompts together into one multi-chapter fic that’s almost certainly going to be 90% fluff, humor, and angst and about 10% actual whump.

Summary
Vahn was an atypical youth. Due to a rare mutation, his blood had the potential to target and attack ailments within the human body. Touted as a universal cure, people had elevated his status above the norm and given him the classification "Panacea". In the media, he was hailed as a great hero who would usher in a new era or human wellness. However, behind the scenes things weren't so bright. Vahn spent his entire youth locked up in a lab with various scientists and research teams using his body and blood to perform endless amounts of experiments. The only solace in his suffering was the various anime and manga made available to him between experiments. For years he nurtured the desire to be free, until at the age of 14 he died when an organization had tried to kidnap him from the lab...
"Finally, I don't have to suffer anymore..."
This was Vahn's last thought as he faded into the endless black abyss...
"You poor soul."

Summary
(A significant crossover fanfic that might be one of my lengthier stories)
"Wake up, Miss Rose... Your time has come again..."
Two decades have elapsed since the Resonance Cascade at Black Mesa, and a long-forgotten hero has resurfaced. Thrown into a train station with no recollection of her true history, 17-year-old Violet Rose accompanies her boyfriend, Aiden Calhoun, as they must navigate through City 17 armed only with sheer determination, adrenaline, a katana, a scythe, and a Snark as their pet. However, Violet quickly discovers that this reality contrasts deeply with the games she played during the False Reality imposed by the G-man. It's not solely the Combine she has to confront; they've allied with a faction once thought to be extinct.
The Patriots.
Now, her mission is to dismantle both of these threats and restore order, joining forces with individuals she never imagined she’d team up with, and discovering a new family after losing her old one. Additionally, she forges friendships with people from the past, some of whom seem oddly familiar.
