Summary
“What the fuck.” Is Danny’s only response as he stares dubiously up at the helmeted man in front of him.
Red Hood. The Crime Lord of Crime Alley. Needs a fake girlfriend to act as bait for his rival crime lords because several of them aren’t falling for his traps anymore.
It also just so happens that a woman named Miss Nightingale is incredibly pretty, hot to trot single, and not at all real except for a few forged documents and several singing gigs.
Danny cannot believe his fucking ears.
“You’re asking me to be your pretend girlfriend?”
“No, I’m telling you.” Red Hood informs him from where he’s had his feet propped up on the table for the last twenty minutes.
Otherwise known as: Red Hood blackmails a shapeshifter in Gotham into being his fake girlfriend.

Rocky hate Stark. by MountainShark
Fandoms: Andy Weir's Project Hail Mary - All Media Types, Marvel Cinematic Universe

Summary
When he initially came to this new reality, Rocky resolved that he would just be Grace's friend.
That opinion changed when Rocky looked for this individual named “Stark”. (He was not bitter, it was just basic research.) The supposed future mate of Ryland Grace. According to this universe's fate, they were set to be with one another.
It took all of Rocky’s fine motor control to prevent himself from snapping the cellular device in half. Of course the “world’s greatest engineer” of the humans was an overshelled pompous ♫♪ ♬♬♪ who was credited for his individual experiments and not his contributions to human society. Contributions that were easily replaced and mostly negative, in Rocky’s opinion.
This was NOT a mate for Grace.
Otherwise known as: Grace reincarnates into the MCU, Rocky follows!

Summary
In hindsight, Grace could very easily realize just how he accidently led Rocky down the path of thinking that humans were amphibians.
However, in his defense when you spend almost 4 years in a cramped spaceship with no proper showers or baths- the idea of going swimming starts to sound absolutely heavenly.
Otherwise known as: 7 times that the Eridians thought that Grace was an amphibian, and the one time he finally found out why there are so many water features in his enclosure.

Summary
My Hero! Adventures was, according to some people, the epitome of a perfect superhero manga.
It ticked all the classic boxes. Bullied protagonist turned strongest individual in the world? Check. Evil villains who preyed upon the downfall of society while claiming they just wanted to fix things? Check. Cute female classmate who totally wasn't interested in the protagonist and is just a good friend? Check.
Abusive childhood bully later defeated and turned into a two bit villain? Mega check.
All that taken into consideration- Katsuki would really like a refund. All that money he spent on the manga wasn't worth it anymore. Not only because of the bad ending, but because now he is the shmuck who gets his face punched in repeatedly before fading into obscurity.
[ That's not true host, the guidance that the My Hero! Series gave you in order to navigate this world is invaluable! (˶ᵔ ᵕ ᵔ˶) ‹𝟹 ]
"SHUT THE FUCK UP!"
Otherwise known as: Fanon Katsuki fucking hates canon.
(A/N: Little knowledge of MHA needed to read this. Just google who Izuku & Katsuki are and I’ll do the rest.)

Summary
“Hobbies and interests?” Damian asked like a robot. He was looking at Danny in the way someone would examine a painting they were writing a paper on. Bored, analytical, like they were expecting a C+.
“I like space, and um, engineering. Like NASA and-” Danny was promptly cut off.
“I like weapons and animals. What are your prospects for dating?” the boy asked, pen quickly noting down whatever it was that he decided from Danny’s response.
Prospects for dating?? A date, preferably???
Otherwise known as: Danny goes speed dating in Gotham. Damian Wayne is a person with a long list of expectations, but thankfully none of them say ‘No Ghosts’.

Surviving as a Villain- I'm Trapped in My Favorite Comic as the Worse Scum?! by Anonymous
Fandoms: Danny Phantom
19 Sep 2026
Tags
Summary
Dark Phantom is a runaway hit of an action comic, boasting sales that would make the Big Two grind their teeth in jealousy and a run that was long enough that the children born at the beginning could start drinking by the end.
Most people who read it would have been thrilled to find themselves in the world they loved, but most people weren't being transmigrated into the body of one scum villain called Vlad Masters.
Keeping to the plot means keeping himself alive, but that also means ruining a lot of lives in the process. He hopes that there's a better way to through this without dying, but with the way this world is written, does he even have a chance? And why does it seem like every character is acting OOC?

Accomplishments of a Doomed Crown Prince by quags1re

Summary
spoilers for hsr 3.3
When it comes to predatory, soul-sucking gacha games, Cosmic Impact Rail Zero was probably the worst of the worst. Did it have incredible characters? Yes. An engaging storyline? Double yes. Did it make Mydei want to blow his entire paycheck on weapons and skins and more rolls? Of course it did.
But it also killed off basically every character in the game, including the crown prince that shared Mydei's name– Mydeimos the Undying, Son of Gorgo. How the hell was that even possible?! He literally had undying in his title!?
So when the developers ask for feedback, Mydei goes off on a heated tangent– and finds himself reincarnated as his namesake. You know– the doomed prince, destined for a life of hardship? Destined to die?
Not if Mydei has anything to say about it.

Summary
“You…” Seungcheol says, between huffing for air, “You are so— did I accidentally marry a vampire? This is unbelievable. Sunlight makes you nauseous?”
“Baem… Baempaio?” Jeonghan says, choosing to ignore the rest of the sentence.
Seungcheol just had to accidentally declare to a crowd that he's going to marry the main love interest Yoon Jeonghan after the latter is pregnant and abandoned by the douchebag main character of the novel.
Pregnant? Main character? Love interest? Novel? Well, Choi Seungcheol — a simple salaryman — has transmigrated into an omegaverse Joseon period novel!!
