Summary
Thor watched as Thanos's merciless grip around his brother's throat tightened, the life draining from Loki's eyes as the mad Titan crushed his neck; pierced his best friend’s heart, slaughtered his people and took away the only family he still had left. He watched as the flames consumed his home, reducing everything he cherished to ashes, while the Grandmaster’s ship crumbled into oblivion.
He begged the Norns for a second chance as he clung onto his once-again-brother’s cold dead body, his cries for mercy swallowed by the inferno.
He wished, and when he opened his eyes back in his room in his long-destroyed home-land, six months after Loki’s fall into the void; he knew he had to change everything. He was given a second chance, and he wouldn’t live to regret it this time.
Although I appreciate your kindness, I’m really not interested in payed commissions! Pls stop spamming!

Summary
In the distant future, a child with a miraculous quirk to spin dreams into reality reads a certain comic book, gets attached to the ragtag main characters, and makes an innocent, imperfect wish. They decide the characters deserve a chance at a happier ending.
The league of villains wake up at Kamino with all of their memories from the war in tact. Given a do-over, they're all determined to get a better ending. Unfortunately, having knowledge about the future doesn't guarantee that their changes won't result in even more complicated, messier issues. They’re still villains, after all. But they’re together again, and that’s the one thing they refuse to lose this time. They’ll tear the timeline apart before they let it break them the same way twice.

Summary
**New chapter Thursdays!**
What if Megumi’s mother wasn’t dead?
Butterfly Effect follows canon from Megumi Fushiguro’s point of view but this time, he isn’t alone.
With Allura back in his life, Megumi grows up with a quiet, steady presence at his side: someone who cooks, listens, worries, and refuses to let him disappear into himself. As jujutsu society hurtles toward the events of canon, her presence doesn’t stop the tragedies, but it changes how they land.
A slower, character-driven rewrite of Jujutsu Kaisen that explores the spaces canon rushed past: training days, family dinners, grief, healing, and the bonds that form when survival isn’t something you face alone.
Canon events remain. The consequences do not.
A continuation of Blue Moon

Brynlee is reincarnated with a Gamer System and immediately bugs the hell out of it by requesting they add a gacha feature. But who cares about consequences, right? She's going to live her life to the fullest, make it everyone's problem, and save as many people as possible in the process!

Summary
Life for Izumi Midoriya had never been great, not since she was diagnosed as quirkless.
Singled out by everyone around her for her lack of a quirk, bullied by those she once called friends, ignored by her teachers, and told that she could not be a hero without a quirk by the hero she admired the most.
Broken and unable to take any more, she decides to end it all. But she was saved, not by a hero, but by a simple man who offered her help.
Now, despite still being broken, with people supporting her and the number one hero training her to help make amends for his actions, she is ready to achieve her dream of becoming a hero.
Even though the road ahead may be rocky, she will not be walking it alone. Early into her training, she finds a robot wolf, a relic from a madman's crusade a decade ago, capable of emulating quirks.
With the power of her newfound mechanical friend, coupled with that of One for All, Izumi sets forth on her journey to become a great hero. All the while, forces watch her from the shadows.

Summary
Sonic the Hedgehog, a franchise with plenty of debated Eras and even more Continuities, some far more dangerous then others for an isekai victim as human as the egg-headed main antagonist himself with no super-intelligence or cheats or systems to speak of. Just meta-knowledge, lots of it, and by extension, plenty he can do with it.
Sonic Films? Fine. Sonic X, Boom, and Prime? Manageable. Gameverse? Dicey, but doable. Archie and Fleetway Comics? No thanks. Sonic SatAM and Underground? Better than dealing with any EXEs, still wouldn’t even if his second life depended on it. Shame that he has no choice in the matter.
At least he can decide what to do after the fact, make the most of this situation he’s stuck in. So what to do then? Join GUN? As if. Go the Chris Thorndyke route? Pass. Babysit the cinnamon roll-haired hologram that got carried along for the ride? Meta supposes that, exploiting plot holes aplenty, and causing chaos for all things canon will have to do.
